  • Phenotypic Evaluation of Heritability, Agro-Morphological and Yield
           Characters of Sixteen Amaranthus Linn. Genotypes

    • Abstract: The field experiment was conducted to evaluate the heritability, genetic variance, agro-morphological and yield characters of Sixteen Amaranthus genotypes. The seeds of the sixteen (16) genotypes of Amaranthus evaluated in this study were; NG/AA/MAY/09/027, NG/AA/03/11/010, NG/AO/11/08/042, NG/AO/11/08/039, NG/SA/DEC/07/0423, NG/SA/DEC/07/0412, NGB01667, NGB01601, NGB01283, NGB01271, NGB01276, NGB01259, NGB01644, NGB01234, NGB01613 and NGB01662. The results showed that there were variability performances in growth and yield characters of Amaranthus genotypes. NG/AA/MAY/09/027 and NG/AO/11/08/039 had the best growth characters while NG/AO/11/08/042 had best yield performance compared to other genotypes. The stem length recorded the best heritability estimate of 95.5% while weight of dry leaf, weight of fresh and dry inflorescent had least (47.7%). The plant height had a positive significant correlation with number of leaf (r = 0.53), leaf width (r = 0.57), number of branches (r = 0.56) but a strong positive correlation with stem length (r = 0.97), stem girth (r = 0.75), number of inflorescent (r = 0.68), inflorescent length (0.64) and inflorescent width (r = 0.72). Prin. 1 accounted for the highest variation in growth and yield characters with proportion of 0.3376 and eigen value of 4.7269, while Prin. 14 was the least with proportion of 0.0003 and eigen value of 0.0038. Therefore, there could be genetic improvement of NG/AA/MAY/09/027 and NG/AO/11/08/039 genotypes for further improvement of Amaranthus.
       
  • Botany, Ecology and Diversity of Acacia koa in the Hawaiian Islands

    • Abstract: Acacia koa (koa) is a valuable leguminous timber-wood tree endemic to the Hawaiian Islands. Over the past century, conversion of some native forests for agriculture and ranching, uncontrolled spread of invasive plant species and outbreak of a deadly fungal wilt disease severely reduced A. koa forests. However, recently there has been a growing interest in re-establishing A. koa as an agroforestry tree because the tree has significant importance in economy, ecology and culture of Hawai‘i. This review presents the current knowledge on A. koa, including its ecological roles, various morphological forms, genetics, evolution and development of methods for seedling selection and propagation. A better understanding and awareness of the nature of A. koa will help successful development of wilt-resistant A. koa trees with high wood quality that can support Hawaii’s ecology, economy and culture.
       
  • Winter Forage Program Benefitted Small-Scale Goat Producers

    • Abstract: Small and limited resource farmers are raising goats on pastures in the southeast USA. Nevertheless, many of these farms do not have productive and quality pastures to support the nutrient requirements of their animals. Information on forages that are suitable to improve goat pastures and sustainably grazing those pastures with goats is still lacking. Study objectives were to (1) find winter forages suitable for goats, (2) evaluate the productivity and quality of these forages and (3) assess the benefits farmers would receive from pasture improvement and grazing management. Two separate studies were conducted, one in Selma and another in Phenix City, Alabama, USA in 2012 and 2013 (September/October-April). Each study was designed as a randomized complete block with three replications. Five legumes: Arrowleaf clover (Trifolium vesiculosum Savi), berseem clover (Trifolium alexandrinum L.), crimson clover (Trifolium incarnatum L.), hairy vetch (Vicia villosa Roth) and winter peas (Pisum sativum L.) were grown with Marshall ryegrass (Lolium multiflorum Lam.) in 40:60 legume: Grass ratio on separate strips. A sole Marshall ryegrass strip was planted as a control. Goats’ preference for and productivity and quality of forages and benefits associated with winter pasture and grazing were evaluated. Goats readily grazed all forages but winter peas at the very first exposure; from the second exposure onwards, goats grazed winter peas well. The mixtures of crimson clover and Marshall ryegrass and hairy vetch and Marshall ryegrass produced the most. The cost of goat production was significantly reduced because of the development and management of winter pastures. Raising goats on pastures can be much more beneficial than raising them on purchased feeds.
       
  • Effect of Phosphorus Application and Arbuscular Mycorrhizal Fungi
           Inoculation on the Growth of American Jointvetch and Greenleaf Desmodium

    • Abstract: This study examined the growth and Arbuscular Mycorrhizal (AM) colonization of two tropical forage legumes, namely, American jointvetch (Aj) and Greenleaf desmodium (Gd), at two phosphate application rates (0 or 10 g P m-2 yr-1; -P or +P), with or without AM (+AM or -AM) in a pot experiment. AM inoculation and P application promoted the growth of both species. AM inoculation in the early growth stages promoted colonization in both species, but P application did not. Nitrogen and phosphorus concentrations were affected by neither AM inoculation nor P application. Nitrogen uptake in both Aj and Gd, however, was affected by both AM inoculation and P application. Phosphorus uptake was affected by AM inoculation in Aj and by P application in Gd. The results suggest that both P application and AM promoted legume growth and AM colonization was not suppressed by P application. Nevertheless, plant responses to the treatments varied with species and growth stage. 
       
  • Global Status of Herbicide Resistance Development: Challenges and
           Management Approaches

    • Abstract: Chemicals are widely recommended for the suppression of weed in crop land. This paper attempts to a greater integration of ideas into the development of herbicide resistance. This may lead researchers to focus less on simply defining herbicide resistance and more towards comprehensive investigations of the resistance development. Weed expert in collaboration with plant biologists can work in synergy to come up with better approach and innovation aimed to curtain herbicides resistance challenges. Chemical herbicides exert undue pressure on weed fitness and the diversity of weed community’s changes over time in response to both herbicides and other strategies imposed on them. Repeatedly and intensively, the regular application of herbicides with similar effect may swiftly result in population shifts to tolerant, difficult to suppress and ultimately result to weed community that is herbicide resistant, particularly in absence of using herbicides with different modes of action. Weed expert and evolutionary biologists have to work in synergy toward an improve and broader knowledge of plant resistant development. This collaboration is likely to proffer innovative solutions to the herbicide resistance challenges.
       
  • Weed Management in Sesame Field (Sesamum indicum L) Using Wheat Straw and
           Tillage or no Tillage Systems

    • Abstract: A field trial was achieved to test the response of weed and sesame crop to use wheat straw and tillage or no tillage systems. The experiment treatments were include; no tillage without straw, tillage without straw, tillage with straw, incorporated with soil and straw as cover crop (no tillage). The result shown that weed density and biomass have high significantly suppression when wheat straw applied as cover crop and without tillage soil compared with soil tillage without straw treatments, while no significant different noticed between treatment that no tillage without straw and tillage with straw incorporated with soil treatments. Using wheat straw as cover crop significantly improved sesame yield and yield components about 50% more than using wheat straw as incorporated with soil treatment and no tillage without straw treatment. This increase in sesame yield can be attribute to amended of capsules number per plant (53.2 capsules) and number of seed per capsule (54.6 seed) compared with 18.1 capsules per plant and 53.6 seed per capsule in tillage without straw treatment . The results of this study have led to the conclusion of possibility using wheat straw hopeful approach to amended sesame planting when used as cover crop.
       
  • Susceptibility of Mango Varieties to Anthracnose Fruit Rot in South West
           Nigeria

    • Abstract: Anthracnose fruit rot is the most devastating postharvest disease of mango fruits in Nigeria. This study, investigated the susceptibility of mango varieties commonly grown in South West Nigeria to fruit anthracnose. Four locations (Ayetoro, Ibadan, Ogbomosho and Agege) in South west Nigeria, which fall along mango production belt, were selected for this study. Physiologically matured mango fruits freshly harvested separately from Alphonso, Julie and Ogbomosho varieties were ripened at room temperature for 16 days under alternating 12 h light and dark periods to assess the incidence and severity of fruit anthracnose in each variety. In addition, freshly harvested healthy fruits were deliberately inoculated with spores of Colletotrichum gloeosporioides to evaluate the degree of susceptibility of the tested varieties. Results showed that Ogbomosho variety had the lowest percentage of 66.7% disease incidence and 44% disease severity. Similarly, lesion diameter was highest in Alphonso variety (1.18 cm) with the least (0.91 cm) in Ogbomosho variety. The study found Ogbomosho variety less susceptible to anthracnose and consequently recommended it to farmers.

  • Improving Farmers' Income and Soil Environmental Quality through
           Conservation Agriculture Practice in Bangladesh

    • Abstract: The study was accomplished for assessing conservation agriculture practice's impact on farmers' income and soil environmental quality in Bangladesh. Majority of the farmers were within the late majority group in terms of adopting this farming practice. Average annual agricultural income of focal farmers was increased at a higher rate compared to proximal and control farmers after adopting this practice. Most of the focal and proximal farmers stated about improved soil environmental condition where majority of control farmers stated about constant soil environmental condition in this regard. Minimum tillage operation, permanent organic soil cover and application of compost and vermicompost were found significant factors under conservation agriculture affecting soil environmental quality. The problems faced by the farmers included high price of inputs, lack of institutional credit, lack of knowledge about conservation agriculture, etc. Input support, incentive, training programmes and extension services should be well executed by different government and non-government organizations for building consciousness and enhance the knowledge of the farmers on conservation agriculture practice.
       
  • Diallel Analysis and Evaluation of Parents and F1 Progenies of Maize (Zea
           mays L.) for Tolerance to Drought and Striga hermonthica (Del.) Benth in
           the Guinea Savanna Agro-Ecological Zone of Ghana

    • Abstract: Field studies were conducted to evaluate 6 parents and 30 F1 hybrids of maize for tolerance to drought and Striga hermonthica in Nyankpala, Ghana during the 2014 and 2015 cropping seasons. These genotypes were evaluated for two years on single-row plots of three replicates, in a randomized complete block design. The control plants were planted in July each year which is the normal and usual time of planting of maize in the study area, whilst the water-stressed plants were planted six weeks later to ensure that their growth period coincides with the drought period. The Striga hermonthica infested plants were also planted at the normal time of planting maize in the study area. Results showed that highly negative significant GCA effect for the parent populations was observed in TAIS03, KOBN03-OB, DT-STR-W-C2 and IWD-C3-SYN-F2 for majority of the traits. The four parents were good general combiners for majority of the traits observed. For the F1 hybrids, KOBN03 × DT, DT × TAIS03, TAIS03 × KOBN03, IWD × GUMA03, GUMA03 × DT, GUMA03 × SISF03 and SISF03 × TAIS03 gave the highest negative significant SCA effect for most of the traits studied and are good specific combiners for the traits observed. The highly significant negative GCA and SCA effects of parents and F1 hybrids for majority of observed traits showed that those genotypes were highly tolerant to drought and/or Striga hermonthica. Drought rating, leaf-rolling rating, striga rating, striga count and Anthesis-Silking Interval (ASI) had been reduced significantly when plants were watered throughout the experimental period (control) as compared to the water-stressed and striga-infested plants. However, grain yield, hundred-grain weight, number of ears harvested, plant height, ear height, days to 50% anthesis, days to 50% pollen shed and days to 50% silking were significantly higher (p<0.05) for the normal (control) plants as compared to the water-stress and striga-infested plants. In drought-prevalent or striga-infested geographical areas like Northern Ghana, parent and F1 hybrid populations such as (TAIS03, KOBN03-OB, DT-STR-W-C2 and IWD-C3-SYN-F2) and (KOBN03 × DT, DT × TAIS03, TAIS03 × KOBN03, IWD × GUMA03, GUMA03 × DT, GUMA03 × SISF03 and SISF03 × TAIS03) respectively, can be used for increased grain yield.
       
  • Stable Nitrogen Isotopic Changes in Winter Wheat (Triticum aestivum L.)
           Induced by its Growth Temperature

    • Abstract: The nitrogen dynamics of plants can be quantified using the variation in their δ15N level. This reveals details of plant physiological characteristics and the relationship between plants and their growth conditions. To better understand plant nitrogen dynamics and the effects of external temperature changes on their nitrogen isotopic composition, we investigated the δ15N characteristics in Triticum aestivum and its mother soils during the plant's life cycle. We found that under field conditions, the plant's leaves and roots δ15N significantly changed. The δ15N values in Triticum aestivum changed from -1.6‰ to -8.1‰ for leaves and from -2.0‰ to -8.8‰ for roots, respectively. δ15N values for both, the leaves and roots were positively correlated with temperature. However, the foliar δ15N corresponded more strongly to air temperature, while the root δ15N corresponded to soil temperature. δ15N values of leaf and root both changed around 0.2‰ in response to a 1 degree change in temperature. Plant roots or shoot material cannot reflect the whole plant δ15N values due to a considerable difference between the δ15N values of root and leaf. However, the variations in leaf and root δ15N provide useful proxies to trace seasonal plant nitrogen cycles.
       
  • Identifying Factors Influencing Production and Rice Farming Income with
           Approach of Path Analysis

    • Abstract: This research analyzes direct and indirect factors that potentially affected rice quality, rice price at the farmers' level, rice production and farming income. The target population in this research were farmers who farmed on rice land area ranging from 0.5 to 2.0 ha. A multistage, stratified cluster sampling was used in this research. This research employed a survey of 300 household heads, chosen randomly. Results showed that NPK fertilizers (Nitrogen, Phosphorus, Potassium), organic fertilizers and labor had a direct effect on rice production. Rice quality had a direct effect on its price at the farmers' level, while organic fertilizers and labor directly affected rice quality. Labor had a negative correlation to rice quality, showing that technologies were very much needed to improve. Rice price at the farmers' level and production had a direct effect on the income of rice farming, while the organic fertilizers had an indirect effect. These results have the potential to help the government and agricultural professionals design effective agricultural interventions to increase rice quality, price at the farmers’ level and production so that farming income could increase.
       
  • Determinants Factors of Agricultural Extension Services Performance and
           Impacts on Farmers' Behavior

    • Abstract: Agricultural extension plays an important role in improving the quality of human resources, also it function as a learning process for the main actors so that farmer will be able to help and organize themselves in accessing market information, technology, capital and other resources. Problem that arise among stakeholders have been widely debated.  Since then, determinant factor of Agricultural Extension Services (BPP) performance should be identified and how it will impact on farmers behaviour. There is a strong assumption that, BPP performance will affect agricultural development, but it is very difficult to determine by factors. The research objectives were to analyze determinants of BPP performance and impact on farmers behaviour. This research was conducted in South Sulawesi Province, Indonesia by selecting 109 BPP based on Slovin Method. The analysis analized with Structural Equation Modeling (SEM) using LISREL software. The results showed that development of  BPP; management BPP, human resources, assisted farmers, resource of BPP, adaptation of BPP are positively affect Action Program of BPP. In addition, these determinants affect farmers behaviour in terms of farmers competency and participation through indirectly action program. This leads to argue that in order to improve farmers behaviour (improving competency and participation), it is needed to step up performance of BPP (making action program properly, in other words) through extension program improvement, groups activity plan and operational cost management.
       
  • The Single and Combined Effect of MC4R and GH Genes on Productive Traits
           of Pigs

    • Abstract: The aim of our work is to identify the single and combined effect of MC4R and GH polymorphism genes on growth and reproduction traits of pigs. The study was carried out on 204 crossbred F1 females (?Landrace ? ?Large White) of the Breeding Farm in Russia. The analyzed productive traits were: The number of Days to 100-kg (Days to 100 kg), Length of Body (LB), Backfat Thickness (BF) and Number of piglets Born Alive (NBA). The G1426A of MC4R and G316A of GH polymorphism were determined by PCR-RFLP method. The results showed a significant additive effect of MC4R (G1426A) on all analyzed traits and dominant effect on LB and NBA. With better Days to 100 kg associated genotype AA/MC4R, but the best indicators LB, BF and NBA installed for genotype GG/MC4R. The single effect of GH was determined to BF (dominant effect) and NBA (additive effect). The effect of genotype AG/GH on BF was observed in combination with genotypes of MC4R. In our studies we observed only six combinations of MC4R and GH genes instead of nine theoretically expected. The detected genotypes were following: AA/MC4R - AG/GH, AA/MC4R - GG/GH, AG/MC4R - AA/GH, AG/MC4R - AG/GH, AG/MC4R - GG/GH, GG/MC4R - GG/GH. The combination effect is defined for genotype AA/MC4R with genotypes of GH. The best means for all studied productivity traits were observed for the combination AA/MC4R-AG/GH. The combined effect of genotype AG/MC4R with genotypes of GH was not identified, but it was observed independently influence of MC4R on Days to 100 kg and NBA and GH on BF. The genotype GG/MC4R was detected only in combination with GG/GH genotype, which does not allow evaluating the combination effect of other GH genotypes.
       
  • The Occurrence of Entomopathogenic Fungi on Mineral and Peat Soils in
           Peninsular Malaysia

    • Abstract: The aims of this study are to isolate and identify Entomopathogenic Fungi (EPF) from mineral and peat soils in relation with the soil physico-chemical parameters. The mineral soil was sampled from the MPOB Research Station Hulu Paka in Terengganu, whereas peat soil was sampled from the MPOB Research Station Teluk Intan in Perak. Isolation of these fungi was carried out using a selective medium. Morphological characteristics of fungi were studied by observing the mycelium and conidia grown on agar plates using a light microscope. Soil physico-chemical parameters such as pH, water content, carbon and nitrogen content were also determined. Two species of EPF isolated from both types of soils were identified as Isaria amoenerosea and Metarhizium anisopliae. On potato dextrose agar, the colony of I. amoenerosea was pink in colour and slow growing with floccose mycelium which producing conidiophores with 3 to 4 phialides. The conidia were subglobose or irregular shapes between 2.0-3.0 &micro;m long &times; 1.7-2.0 &micro;m wide. The colony of M. anisopliae was whitish yellow and turned to dark green when matured; slow growing with floccose mycelium. The conidia were cylindrical with the dimension ranging from 6.0-7.0 &micro;m long &times; 2.0-2.8 &micro;m wide. The result shows that the occurrence of I. amoenerosea was more dominant than M. anisopliae. In mineral soil, out of 30 samples, I. amoenerosea was isolated from 25 soil samples (83%), while the M. anisopliae was only found in 15 samples (50%). In peat soil, out of 36 samples collected, 26 samples (72%) were found with I. amoenerosea, while the fungus M. anisopliae was isolated from eight samples (22%). In this study, the occurrence of EPF on mineral soil was higher than from peat soil, which was possibly due to low water content, high soil temperature and low C/N ratio.
       
  • Effect of Sticky Trap Color and Height on the Capture of Adult Oriental
           Fruit Fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) on Chili
           Pepper

    • Abstract: Oriental fruit fly, Bactrocera dorsalis, (Hendel) (Diptera: Tephritidae) is a destructive pest to many major crops, including chili pepper (Capsicum frutescens L). The insect can cause yield loss up to 100% in the absence of any control measures. One control tactic commonly used by pepper growers to control the fruit fly is sticky trap to capture the adults. The purpose of the current study was to elucidate the effect of trap color and height on the fly capture. The results showed that yellow trap was consistently the most attractive trap amongst the other trap colors tested with an overall average of 62.6 adults per trap during the study. The second most attractive traps were white and green traps with overall averages of 45.2 and 40 adults per trap, respectively. The attractiveness levels of the red and blue traps were comparable each other with overall averages of 29.4 and 25.4 adults per trap, respectively. The least attractive trap was black trap with an overall average of 17.1 adults per trap, which was significantly lower than the other trap colors. In addition, traps set up at 25 and 50 cm above the ground captured significantly more adults (187.8 and 171.9 per trap, respectively) compared to those set up at 75 and 100 cm above the ground (60.8 and 37.1 per trap, respectively). When the combination of the color and height of the traps were analyzed, the yellow, white and green traps set up at 25 and 50 cm above the ground caught the highest numbers of adult fruit flies and they were not significantly different each other. Thus, these combinations should be recommended to the pepper growers to control the insect in their plantations.
       
  • Validation of SSR markers associated with Submergence Tolerance in Rice
           (Oryza sativa L.)

    • Abstract: The present work is devoted to the validation of SSR markers associated with submergence tolerance (Sub1A) QTLs in rice. It was shown that only microsatellite markers RM 7481 differentiates donor lines and recipient variety. Based upon the results of DNA analysis with the marker of the RM 7481 of the F2-plants, the 14 homozygotes by the locus Sub1A, 40 samples carried Sub1A in the heterozygous state, 22 plants inherited only alleles from the recipient variety Novator were identified. Survival analysis of parental and hybrid plants (21 days after germination) showed that the most submergence tolerance forms were donor lines of Sub1A loci and F2-plants carrying Sub1A locus in homozygous and heterozygous state according to the data of molecular genetic analysis. Thus, it was shown that RM 7481 microsatellite marker is effective for breeding of submergence tolerance rice using Russian elite cultivars.
       
  • An Empirical Analysis of Supply Response of Rubber in Malaysia

    • Abstract: Supply response of rubber to changes in economic incentives is analysed using co-integration approach. Time series data is taken for the period 1990 to 2014 and the vector error correction model framework has been applied. The empirical results confirmed the existence of a unique long-run equilibrium relationship among planted acreage, the relative price of rubber and price of fertilizer. Further, the estimates suggested that rubber supply is significantly influenced by the relative price of rubber and the price of fertilizer. The estimated short- and long-run elasticities of acreage with respect to relative price are respectively 0.04 and 0.77, while the short- and long-run elasticities of acreage with respect to fertilizer price are -0.20 and -0.28 respectively. The study recommends the design of an appropriate economic incentive structure to stimulate output and hence the income of farmers.

  • Evaluation of Antiviral Activity of Different Medicinal Plants against
           Newcastle Disease Virus

    • Abstract: Newcastle Disease (ND) is a highly contagious viral disease that has a tremendous negative impact on the poultry industry worldwide. Plant extracts were prepared from five different medicinal plants and applied against Newcastle Disease Virus (NDV) to evaluate the antiviral replication in Specific Pathogen-Free (SPF) chicken embryos. Three dilutions from each plant extract were prepared and mixed with a fixed titer (104 EID50/mL) of virulent NDV strain Herts 33. The mix was inoculated into nine-day-old SPF chicken embryos that were monitored for five days. Real-time PCR and hemagglutination tests were conducted to evaluate the activity of NDV and its viral RNA titer. Some plant extracts showed a complete inhibition of NDV evidenced by the absence of embryo deaths, the absence of HA titer and viral RNA in the allantoic fluid. These plant extracts were from Moringa peregrina (leaves), Acacia cyanophylla (leaves), Eucalyptus camaldulensis (fruits) and Pistacia atlantica (leaves and stems). Other plant extracts showed partial inhibition of NDV, such as Ceratonia siliqua (leaves) and Eucalyptus camaldulensis (leaves). This experiment shows the potential of using medicinal plants as antiviral agents.
       
  • Using the Environmental Kuznets Curve to Study the Mutual Effects between
           CO2 Emissions and Economic Growth in Jordan

    • Abstract: This study analyzes the dynamic relationship between economic growth and CO2 emissions in Jordan using the Environmental Kuznets Curve. The study looks at the direction of the causal relationship both in the long and short-run to determine the mutual effects between the two variables during the 1980-2010 period. Using the ARDL bound testing approach and the Vector Error Correction Model (VECM), the study shows that the results are consistent with the Environmental Kuznets Curve (EKC) hypothesis. Furthermore, the study shows the existence of a bidirectional causal relationship, both in the long and short run, between economic growth and CO2 emissions. Based on that, the authors conclude that environmental issues must be taken into consideration when formulating economic policies, as well as using environmentally friendly technologies in the manufacturing and transportation sectors.

The production of mutant kidney bean was between 3.97 tons/ha up to 5.28 tons/ha and the average production was 4.71 tons/ha. The average production of control was 2.60 tons/ha, in order that the production was significantly increased by 44.80%.
       
  • The Resistance Evaluation of Dry Subtropics Brown Soils to Heavy Metal and
           Oil Contamination by Biological Indicators

    • Abstract: Contamination of brown calcareous soils with Cr, Cu, Ni, Pb and oil leads to deterioration of their biological properties. There is a reduction in activity of catalase and dehydrogenase, an abundance of Azotobacter genus bacteria, cellulolytic activity and the length of radish roots. As a rule, there is a direct relationship between the content of contaminant in the soil and degree of deterioration of biological properties of the soil. According to the degree of negative impact on the biological properties of brown soil heavy metals form the following series: Cr > Cu > = Pb > = Ni. The pattern that chromium is more toxic and copper, lead and nickel have less and similar to each other degree of toxicity was established earlier in research conducted by the same method, with other soils in southern Russia. According to the degree of resistance brown soils are close to chestnut soils, they are less stable than chernozems and more stable than brown semi desert soils. Regional standards of Cr, Cu, Ni, Pb and oil content in brown soils of Ciscaucasia dry subtropics Ciscaucasia are proposed.
       
  • Phenomenon of Thrips (Thysanoptera) Attack on Chili Plant (Capsicum annuum
           L.)

    • Abstract: Phenomenon of Thrips (Thysanoptera) Attacks on Chili Plant (Capsicum annuum L.). Thrips are insects that damage agricultural plants such as chili plants (Capsicum annuum L.). The attacks which was caused by the thrips starting from mild to severe attacks. In Jambi province there was not any report about the attacks phenomenon of thrips on chili plants. The research aimed to analyze the phenomenon of thrips attack on chili plant. The study was conducted by observing the attacks of thrips on the leaves chili plant. First, observations were done on 160 chili plants in the infested cage thrips which obtained from chili plantation, cucumbers and squash. Observations were carried out at the part of affected leaves, color, shape and location of the attack, leaf structure, chlorophyll content and the content of nitrogen, fats and carbohydrates of affected leaves. Besides, tests Elisa was also done on the affected leaves. Second, observations of thrips population and the attack percentage, as well as the abundance of predators were performed on 400 chili plants in the field experiment in Jambi University. The thrips attack was allowed to happen naturally without spraying plants by insecticide. Observations in captivity found that thrips attack occurs on the upper leaf surface, occurs at the base, the middle and the edges with silvery attack. Thrips attacks on chili plant lower chlorophyll content and damage the structure of the leaf cells. Levels of nitrogen, fats and carbohydrates of chili leaf which attacked by thrips were not significantly different from control leaves at the level of 5%. Elisa test results showed that the leaves were attacked by the thrips which derived from chili plantation and host plant do not contain Tospovirus. Results of research in the field shows that the population of thrips, the percentage of the attack and the abundance of insect predators of thrips fluctuate and the highest is at the age of 8 mst chili plants. There are 15 species of predatory thrips were found in the field experiment of Jambi University. The members of Sphecidae, Araneidae, Theridiidae and Coccinellidae were found mostly.
