  • Insecticidal and Repellent Activities of Four Essential Oils Against
           Camponotus Compressus and Dolichoderus Affinis

    • Free pre-print version: Loading...

      Abstract: Abstract Ants are one of the serious household pests continuing their destruction in household products ranging from food stores to furniture. For controlling such household pest, attention needs to be given on edible, medicinal, plant-based essential oils (EOs) for fixing safety issues of constant contact and indirect consumption by human after indoor application. In the present investigation, we evaluate the insecticidal and repellent activities of edible, medicinal, plant-based EOs of Allium sativum, Curcuma longa, Ocimum sanctum and Syzygium aromaticum against two household ant species, namely Camponotus compressus and Dolichoderus affinis. Among the four essential oils, Allium sativum oil showed the most potential insecticidal effect with LC50 value of 1.71 µl/250 mL air against Camponotus compressus and 2.32 µl/250 mL air against Dolichoderus affinis, while Syzygium aromaticum oil showed the highest repellency against both the targeted ant species. From the findings, we could infer that the selected plant EOs are potential candidates for household ant control as they are effective, extracted from edible products and hence safe for consumption.

      Abstract: Aim To characterize Th1/Th2/Th17 cytokine profile (IL-2, IL-4, IL-6, IL-10, TNF-α, IFN-γ, and IL-17A) among different stages of COVID-19 infection. Methods This was a cross-sectional study which included six healthy individuals and 68 patients who were admitted with COVID-19 in the Department of Medicine, at All India Institute of Medical Sciences, New Delhi, from July 2020 to September 2020. Patients were categorized into mild, moderate, and severe COVID-19 groups, and serum samples were drawn for the measurement of Th1/Th2/Th17 cytokines (IL-4, IL-6, IL-10, TNF-α, IFN-γ, and IL-17A) which was done by BD™ Cytometric Bead Array. Results All the cytokines showed dynamic expression in the COVID-19 group, of which only IL-6 was statistically significant. Among the three severity groups of COVID-19, increased severity did not transform into increased cytokine level, with the exception for IL-6, which was statistically significant. Conclusions In our small sample study, six cytokines expressions were evaluated however most of them were elevated in COVID-19 patients but were not statistically significant except IL-6.

  • Extension of the Known Range of Chinkara and its Conservation Importance
           in Karnataka, India

    • Free pre-print version: Loading...

      Abstract: Abstract Chinkara (Gazella bennetti) is a widespread antelope in the arid and semi-arid regions of Deccan Peninsula, but it is relatively unfathomed in the southern part of its distribution range. We report the first photographic evidence of chinkara from Ballari district of Karnataka that comprises six camera-trap records representing six different individuals from Chiribi Reserved Forest. During June–August 2019, chinkaras were detected through camera trapping surveys in a single forest patch, with predominately dry scrub forest. This finding adds information on the extended distribution range of the species  across the globe. Presence of a fawn indicates the existence of a viable population with breeding pairs, which is a positive indication in terms of conservation importance of the region. An extensive occupancy survey in this forest patch and neighboring areas would help in acquiring a better understanding of the distribution of this elusive species and facilitate protection, conservation and restoration of its critical habitat for sustaining their population.

  • Promotion of Food and Nutrition Security Through Farm Technologies and
           Behavioural Change Communication, Targeting Women

    • Free pre-print version: Loading...

      Abstract: Abstract Dietary diversification through crop diversification in a farming community is a useful low-cost strategy for combating micronutrient (Mn) deficiencies (hidden hunger) in Indian diets. With advocacy and awareness, even farmers with small and marginal land holdings can be persuaded to divert small pieces of land from traditional crops, to MN-dense crops like vegetables, fruits, pulses, and millets. Backyard poultry with high egg-yielding birds is a good option to promote, since eggs are highly nutritious. To ensure that this farm produce is primarily consumed at home and only excess sold, there has to be a robust strategy of behavioural change communication. Educational intervention/technology transfer can be through a combination of centralised training programmes, hands-on training in farms, as well as through distribution of simple educational pamphlets. Since nutrition security goes beyond food security and includes safe environment, drinking water, and health care, the educational package should be a holistic one. Pregnant women and mothers with under 24-month-old children (the first 1000 days after conception) are the most effective group to target. Recent studies including the one reported here in a tribal community show that such a strategy can help crop diversification, as well as marked improvement in the mothers’ understanding of health, food, and nutrition. Significant improvement in household vegetable consumption can also be achieved.

  • CRISPR/Cas9-Based Genome Editing as a Way Ahead for Inducing Production of
           Bioactive Metabolites in Endophytes

    • Free pre-print version: Loading...

      Abstract: Abstract Natural product research from plants has a long history of contribution in agriculture, human medicine and animal health. The success of targeting and screening novel bioactive secondary metabolites has been elevated manifold with increasing endophyte-related research and development. Numerous studies have documented synthesis of many plant-originated compounds from endo-microbiomes. Genomic editing based on CRISPR/Cas9 technology (CCT) has emerged as a useful tool for enhancing yield of desired metabolites derived from filamentous fungi particularly. With such appropriate genomic insight, biosynthetic genetic cluster can be tagged and identified at an accelerated pace in beneficial microbes. The CCT system concurrently edits multiple genes; thereby making multiple site mutations possible in lesser number of experimentation. This fast-tracked transformation procedure exorbitantly improves the low efficiency of previously known genomic editing methods.

    • Free pre-print version: Loading...

      Abstract: Abstract The Kumbh Mela is the largest religious and spiritual mass gatherings on the Earth. In this way, it remains a source of fascination for vast numbers of Hindus throughout the world. Around 240 million pilgrims participated during Kumbh Mela 2019. The Crowd management and the strategy for Security and surveillance have become a big challenge for such huge gatherings. This paper tries to find out the various risk factors and its management. It examines the role and responsibilities of various stakeholders in crowd management. Despite of some difficulties like lack of knowledge of number of people, crowd psychology and its behaviour pattern, this paper provides a comprehensive approach for risk analysis, preparedness, management and mitigation. The purpose is to make spiritual mass gathering events incidence free and enhance user experience by applying design thinking approach. Although this paper tried to cover all the aspects of crowd management and strategies for security and surveillance during mass gathering events, still many more approaches are there which can be further explored. The mega tent city that accommodates nearly millions of pilgrims in the river bed is significant not only for India, but also for mass gathering research at international level to draw policy. This provides the multifunctional issues to study the mega crowd events. This provides the opportunity to generate the field level evidence and document base for disaster management.

    • Free pre-print version: Loading...

      Abstract: Abstract Phytochemical analysis and antioxidant activity in leaves of Cassia fistula, Cassia javanica, Cassia siamea and Cassia suratensis were performed. Dried leaves of C. species were extracted in different polarity gradient solvents for qualitatively of primary and secondary metabolites. Quantitative estimation of phenolics and flavonoids was carried out using FCR and antioxidant activity by DPPH scavenging assay. Phytochemical screening reveals that maximum metabolites are present in ethanol extract in all species as compared to other solvent extracts. Maximum phenolic content was detected in leaves of C. suratensis (200 ± 0.046 GAE/g) followed by C. siamea, C. fistula and C. javanica, respectively. Highest flavonoids were present in C. suratensis and C. siamea (75 ± 0.025 QE/g), respectively. Percentage inhibition (0.02–0.10 mg/ml) was found in C. suratensis (39.72 ± 0.020–91.31 ± 0.001 mg/ml) that is significant. Cassia suratensis was found to be a good source of antioxidants for preventing oxidative stresses-related disease and utilization in therapeutic uses.

  • First report on chromosomal analysis of freshwater prawn, Macrobrachium
           kistnense (Decapoda: Palaemonidae) from Jammu region of Outer Himalayas,
           India

    • Free pre-print version: Loading...

      Abstract: Abstract The genus Macrobrachium, despite having immense nutritional, medical, and ornamental importance, is least explored cytogenetically. One of its species M. kistnense from J&K is an eligible candidate for commercial culturing and can enhance the dietary protein content and economic standard of local inhabitants. There is no previous record of chromosome number and karyotype of this species. Therefore, in the present study, the diploid number and karyotypic characteristics of M. kistnense were worked out by using conventional Giemsa staining and chromosome banding techniques. The diploid chromosome number was found to be 2n = 74 with karyotypic formula (54m + 14sm + 4st + 2t). The characteristic banding patterns were also obtained after Ag- NOR and G-banding. The present study will aid to solve taxonomic ambiguities within the family Palaemonidae and also in general understanding of the course of evolution in order Decapoda.

      Abstract: Abstract The present study records the incidence of Nipaecoccus viridis (Newstead) on Tulsi; Ocimum sanctum from Odisha, India for the first time. Critical observation revealed that infestation starts with the appearance of first and second instar nymphs on the tender portion of the plants. Later, they spread whole shoot and leaves of the tulsi plant. Leaves of highly infested plants become yellowish, gradually dry and later fall down. Two ant species namely Paratrechina longicornis and Solenopsis geminata were associated with this mealybug. Plants grown in shady areas are more prone to this pest infestation and severe infested plants become dried within 1 to 2 months after infestation. Beside O. sanctum, it also infested Euphorbia hirta, Citrus spp. and Rosa spp. Proper care and management practices should be taken as and when this pest being observed on this important medicinal plant.

           Pradesh

    • Free pre-print version: Loading...

      Abstract: Abstract Dynamics of water in the soil has similar importance as other physiological properties in agricultural crop production. We sampled the soil from the vegetative lands of Bundelkhand region upto the depth of 0–15 cm and determined for moisture content, bulk density (BD), rate differential equation, instantaneous loss of moisture and correlation among these parameters. The observation invokes that maximum loss of moisture occurred from the L4, while minimum from the L1 followed 4th and 1st ordered rate differential loss equation. The moisture content followed to vary from 5.39% (L5) to 16.94% (L2). However, the BD values ranged from 1.33 (L4) to 1.14 gm/cc (L3). Apart from this, the moisture content was found to be highly significantly correlated with BD (r =  − 0.359**) and rate loss (r = 0.460**). Therefore, the proper use of land can be intimated by proper selection of plant species as per availability of moisture and its dynamics losses.

  • Estimating the Effect of Bt Cotton on Input Expenditure and Yield: An
           Indian Perspective

    • Free pre-print version: Loading...

      Abstract: Abstract Though it is almost two decades since it was first introduced for commercial cultivation, the scientific community seems not to have reached a consensus yet on the success or failure of Bt cotton in India. In this context, we attempt to find out the effects of Bt on input use and yield in cotton crop using a panel data for 21 years from the nine major cotton-growing states of the country. The results suggested higher yield and lesser input expenditure due to the adoption of Bt cotton. Though the short-run economic benefits due to Bt cotton is well documented in the literature, our finding that the Bt cotton has a beneficial effect even after 18 years of its commercialisation in the country gives reason for remaining optimistic about this technology at least in the near future.

      Abstract: Abstract This article highlights the studies on the influence of coating parameters along with surface roughness on the coating thickness and microhardness. The thickness of the coating was found to increase by 112.72% with increase in surface roughness. The increase in microhardness is found to be 40.20% and 65.13% with increase in particle concentration and current density, respectively. The maximum MH is noticed at higher bath temperature and current density of 50 °C and 2 A/dm2, respectively. The maximum thickness is achieved at the higher particle loading of 6 g/l at roughness of 0.48 μm and 1 A/dm2 of current density.
