  • Insecticidal activities of monoterpenes and phenylpropenes against
           Sitophilus oryzae and their inhibitory effects on acetylcholinesterase and
           adenosine triphosphatases
    • Authors: Mona M. G. Saad; Hamdy K. Abou-Taleb; Samir A. M. Abdelgaleil
      Pages: 173 - 181
      Abstract: In the present study, six monoterpenes [(−)-citronellal, p-cymene, (−)-menthone, α-pinene, α-terpinene, and (−)-terpinen-4-ol] and two phenylpropenes [trans-cinnamaldehyde and eugenol] were evaluated for their contact and fumigant toxicities against Sitophilus oryzae adults. The effects of these compounds on the mortality of S. oryzae adults in stored wheat and their inhibitory effects on acetylcholinesterase (AChE) and adenosine triphosphatases (ATPases) were examined. The tested compounds showed varying degrees of contact toxicity, with trans-cinnamaldehyde (LC50 = 0.01 mg/cm2) being the most potent compound, followed by (−)-menthone (LC50 = 0.013 mg/cm2) and eugenol (LC50 = 0.015 mg/cm2). In a fumigant toxicity assay, the monoterpenes α-terpinene, p-cymene, and (−)-menthone showed the highest toxicities (LC50 = 50.79, 52.37, and 54.08 μl/L air, respectively). Trans-cinnamaldehyde, (−)-citronellal, and eugenol were the least toxic (LC50 > 100 μl/L air). In general, the oxygenated compounds exhibited high contact toxicities while the hydrocarbon compounds exhibited high fumigant toxicities. When tested for their insecticidal activities against S. oryzae in stored wheat, trans-cinnamaldehyde was found to be the most potent compound, with 73.9% mortality at an application rate of 0.5 g/kg and complete mortality (100%) at 1 and 5 g/kg after 1 week of treatment. All of the tested compounds showed AChE inhibition, although (−)-citronellal and trans-cinnamaldehyde presented the strongest enzyme inhibition, with IC50 values of 18.40 and 18.93 mM, respectively. On the other hand, (−)-terpinene-4-ol exhibited the highest inhibition of ATPases, followed by α-pinene and α-terpinene.

  • Laboratory and simulated-field bioassays for assessing mixed cultures of
           Lysinibacillus sphaericus against Aedes aegypti (Diptera: Culicidae)
           larvae resistant to temephos
    • Authors: Paula A. Rojas-Pinzón; Juan J. Silva-Fernández; Jenny Dussán
      Pages: 183 - 191
      Abstract: Aedes aegypti (L.) is the main vector of tropical diseases such as dengue, chikungunya and Zika. Due to the overuse of insecticides, Ae. aegypti resistant populations have increased. Biological control with Lysinibacillus sphaericus (Ahmed) has been used against Culex sp. and Anopheles sp. Although Ae. aegypti is refractory to the binary toxin of L. sphaericus spores, vegetative cells have been shown to be effective against Ae. aegypti larvae. In this work, the effect of L. sphaericus vegetative cells on Ae. aegypti temephos-resistant larvae was assessed under lab and simulated field conditions. L. sphaericus caused about 90% mortality of insecticide-resistant Ae. aegypti larvae under simulated field conditions. Likewise, Ae. aegypti larvae were more sensitive to mixed cultures of L. sphaericus than to individual strains; then, the most effective mixed culture exhibited an LC50 of 1.21 × 105 CFU/mL with Rockefeller larvae and 8.04 × 104 CFU/mL with field-collected larvae. Additionally, we found that mixed cultures composed of two L. sphaericus strains were more effective than a culture formed by the three strains. Our results suggest that mixed cultures comprising L. sphaericus vegetative cells could be useful for controlling temephos-resistant populations of Ae. aegypti, as evidenced by the effectiveness demonstrated under laboratory and simulated field conditions.

           Tortricidae), in traps baited with host-plant volatiles in Chile
    • Authors: Wilson Barros-Parada; Byrappa Ammagarahalli; Esteban Basoalto; Eduardo Fuentes-Contreras; César Gemeno
      Pages: 193 - 204
      Abstract: Studies in Australia and China identified host-plant volatile blends from peach and pear that captured relatively high numbers of Grapholita molesta (Busck). To determine if these blends are attractants in other countries and relative to each other, the two host-plant blends, a laboratory blend identified in Switzerland, and a new “total blend” made by mixing components of all three blends, were field-tested in Chile for the first time. The same solvent type, concentrations, and dispensers as in the original studies, plus an additional concentration and solvent, were used. Only the Swiss blend at the low n-hexane concentration captured significantly more males than the solvent traps, albeit in very low numbers (1.46 ± 1.46, mean ± SEM males/trap/week). Furthermore, host-plant blends decreased male captures in sex pheromone traps, and the effect was dose-dependent for the Chinese and total blends. A laboratory flight tunnel test confirmed the lack of G. molesta male response to the Australian, Chinese, and Swiss plant blends. In the flight tunnel, however, the males responded sooner and in higher numbers to mixtures of sex pheromone with host-plant blends than they did to the sex pheromone alone.

  • Chemical and molecular identification of the invasive termite Zootermopsis
           nevadensis (Isoptera: Archotermopsidae) in Japan
    • Authors: Toshihisa Yashiro; Yuki Mitaka; Tomonari Nozaki; Kenji Matsuura
      Pages: 215 - 221
      Abstract: Numerous termite species have been introduced outside their native ranges by human transport, and some have become invasive. The dampwood termite Zootermopsis nevadensis (Hagen), which is native to western North America, has been introduced to and become established in Kawanishi City, Hyogo Prefecture, Japan. Zootermopsis nevadensis is subdivided into two subspecies based on cuticular hydrocarbon (CHC) phenotypes: Z. nevadensis nevadensis and Z. nevadensis nuttingi (Haverty and Thorne). Here, we identified Z. nevadensis in Japan as hybrids between the two subspecies. Chemical analysis showed the presence of 7,15-dimethylhenicosane and 5,17-dimethylhenicosane in the CHCs of Z. nevadensis in Japan, corresponding to the CHC phenotype of Z. n. nevadensis. Conversely, all mitochondrial cytochrome c oxidase subunit I sequences of Z. nevadensis in Japan were identical to sequences from Z. n. nuttingi and hybrids between the two subspecies from a native hybrid zone in California, USA. In addition, phylogenetic analysis showed that Z. nevadensis in Japan formed a clade with Z. n. nuttingi and hybrids between the two subspecies. Our results show discordance between the chemical and genetic features of Z. nevadensis in Japan, indicating that individuals of Z. nevadensis in Japan are hybrids between the two subspecies.

  • Application of the LAMP assay for the detection of the Argentine ant,
           Linepithema humile (Hymenoptera: Formicidae), from captures of pan traps
    • Authors: Tatsuya Ide; Natsumi Kanzaki; Hayato Masuya; Kimiko Okabe
      Pages: 275 - 279
      Abstract: We applied the loop-mediated isothermal amplification (LAMP) assay to monitor invasions of Linepithema humile (Mayr), the Argentine ant, a notorious invasive insect worldwide. Species-specific LAMP primers were designed on the basis of the partial sequence of the cytochrome c oxidase subunit I region of L. humile. The species specificity and sensitivity of these primers were determined in the laboratory and considered adequate for practical use. We also confirmed that the assay successfully detected L. humile from captures of pan traps, which contained L. humile and several non-target ant species. The assay detected the target species even when the captures contained only a leg or an antenna. Since the LAMP assay is simple and rapid, this assay will contribute to the early detection and accurate identification of L. humile.

  • Response of the wheat rhizosphere soil nematode community in wheat/walnut
           intercropping system in Xinjiang, Northwest China
    • Authors: Peng-hua Bai; Qi-Zhi Liu; Xing-yue Li; Yan-bin Liu; Lin-lin Zhang
      Abstract: Intercropping Persian walnut (Juglans regia L.) and wheat (Triticum aestivum L.) have been widely applied in the Xinjiang Uygur Autonomous Region in Northwest China as a means of reducing soil and water losses and improving both land-use efficiency and economic returns. To understand how changes in soil conditions and nematode community structure can contribute to the evaluation of wheat–walnut intercropping systems from the view of soil fauna, we studied the soil nematode community in wheat rhizosphere soil under both monoculture and intercropping systems for 2 years. The results showed that the pH and total nitrogen and organic matter contents in intercropping systems with walnut trees were decreased compared with those of system with wheat alone. The nematode communities differed significantly between intercropping and monoculture plots, e.g., Rhabditis and Dorylaimus were dominant only in monocultures, whereas Tylenchus was dominant only in intercropping systems. Moreover, intercropping systems resulted in decreased nematode abundance, increased proportions of plant-feeding nematodes, and decreased omnivores/predators, particularly in the second year (2012). The decrease in diversity indices (H′) and ecological indices (WI, EI, and SI) of the nematode communities indicated high disturbance and low soil fertility in intercropping systems. Overall, wheat intercropping with walnut had a significant negative effect on wheat rhizosphere soil conditions.

  • Host suitability of the Mediterranean flour moth for rearing Meteorus
           pulchricornis (Hymenoptera: Braconidae), a polyphagous endoparasitoid of
           pest lepidopteran larvae
    • Authors: Soko Nakano; Jing-Je Gau; Kaoru Maeto
      Abstract: We investigated the host suitability of the Mediterranean flour moth Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) for a polyphagous koinobiont endoparasitoid Meteorus pulchricornis (Wesmael) (Hymenoptera: Braconidae), a common natural enemy of various pest lepidopteran larvae. The estimated probability of adult wasp emergence was 80% or higher when eggs were laid in nearly fully grown larvae of E. kuehniella (fresh weight, > 20.0 mg). The body size of emerged adult wasps increased with the initial weight of the host larvae at oviposition. The fresh weight of adult wasps reared on E. kuehniella was approximately 60% of that when reared on a natural host Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae), and the lifetime fecundity of wasps reared on E. kuehniella was approximately half of that when reared on S. litura. Ephestia kuehniella was shown to be a positive host candidate for the mass rearing of M. pulchricornis, but further investigation is needed to increase the body size of wasps for more practical use of this species as a biocontrol agent.

  • Antipredator response of pea aphids Acyrthosiphon pisum (Hemiptera:
           Aphididae): effects of predation risks from an alternative patch on a
           current patch
    • Authors: Kazuhiko Tamai; Yasuyuki Choh
      Abstract: To escape from predators, herbivorous prey could leave their current patch and relocate to an alternative patch. However, when other predators are present on the new patch, prey are again exposed to predation risk. Thus, patch leaving might be affected by the other predators. We studied patch leaving of pea aphids Acyrthosiphon pisum Harris (Hemiptera: Aphididae) in response to ladybird larvae Harmonia axyridis Pallas (Coleoptera: Coccinellidae) on broad bean Vicia faba L. shoots that were offered as patches for aphids. We tested whether shoot leaving was affected by the presence of predators on alternative shoots under laboratory conditions. Odors from alternative shoots were evaluated as possible cues used by aphids to assess predation risk on the shoots. We exposed aphids to odors from alternative shoots with conspecifics plus either adult or larval ladybirds or larval green lacewings Mallada desjardinsi Navas (Neuroptera: Chrysopidae). Shoot leaving was reduced only when adult ladybirds were present on the alternative shoots compared with controls (i.e., no predators on the alternative shoots). Odors of both adult ladybirds and of conspecifics being attacked by ladybird larvae were required for reduced leaving. Hence, predation risks on current and alternative patches might affect the antipredator responses of aphids.

  • Genetic diversity of the melon aphid Aphis gossypii (Hemiptera: Aphididae)
           in a diversified vegetable growing area
    • Authors: Zhaoke Dong; Yifan Li; Shuang Liu; Zhiyong Zhang
      Abstract: The melon aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a highly polyphagous species. To investigate its genetic diversity among seasonal host plants, we conducted a field study in a diversified vegetable growing area in Beijing, China. The molecular marker mtDNA COI (1563-bp long) was used to analyze the genetic diversity of aphid populations collected from eight plant species belonging to families Malvaceae, Cucurbitaceae and Rosaceae. A total of 33 haplotypes were identified, five of which were shared haplotypes, while the remaining 28 were unique haplotypes. At least one haplotype was shared by all eight A. gossypii populations. Aphid populations showed high levels of nucleotide and haplotype diversity. The genetic diversity indices were maximal on the hibiscus (the primary host), whereas minimal on cucumber and strawberry (the secondary hosts). The analysis of molecular variance showed that most of the variance was distributed within populations. Based on the genetic distances, the eight populations can be divided into two groups, associated with primary and the secondary host plant, respectively. The aphids possibly migrated from Hibiscus to watermelon, thereafter dispersed from watermelon to other secondary host plants. Watermelon was an important host probably due to its early growing season and large planting area. Our results highlighted the need to target the population dispersal for effective control.

  • Comparisons of seasonal fluctuations in Uroleucon nigrotuberculatum
           (Hemiptera: Aphididae) densities between 2003–2004 and 2015–2016 in
           northern areas of its distribution range in Japan
    • Authors: Shuhei Adachi; Takashi Kidokoro; Michio Chiba; Makoto Tokuda
      Abstract: Seasonal fluctuations in herbivore densities are affected by various factors. Solidago altissima was introduced from North America and has spread widely over Japan. Then, an aphid Uroleucon nigrotuberculatum and a lace bug Corythucha marmorata, both associated with S. altissima, invaded Japan in the late 1980s and 2000, respectively. In Miyagi, northeastern Japan, U. nigrotuberculatum and C. marmorata were established in the 1990s and 2012, respectively. We conducted periodic surveys of U. nigrotuberculatum in 2003–2004 and 2015–2016, and of C. marmorata in 2016 in Miyagi. Then, a competition experiment was performed to examine the relationship between them. In 2003, the average maximum daily temperature did not exceed 30 °C and the aphid was continuously confirmed on S. altissima during the census period. In other census years, the temperature exceeded 30 °C and the aphid disappeared in summer. At these sites, C. marmorata was continuously found on S. altissima. The presence of C. marmorata did not negatively affect U. nigrotuberculatum in the competition experiment. In addition, peak densities of U. nigrotuberculatum were higher in 2015–2016 than in 2003–2004. Based on these results, we conclude that U. nigrotuberculatum populations were at least partly affected by high temperature during the summer, but not by C. marmorata invasion in Miyagi.

  • Spatio-temporal variation of strawberry aphid populations and their
    • Authors: María F. Cingolani; Nancy Greco
      Abstract: Aphids are common herbivores in the strawberry crop that can reduce plant vigor and fruit quality and also transmit viruses. Aphid species prefer diverse plant organs, which represent particular habitats of different quality for aphids and for the development of natural enemies’ populations. Different habitat units (young leaves, mature leaves, buds, flowers) of strawberry were sampled fortnightly during all seasons. We identified seven aphid species, namely Chaetosiphon fragaefolii, Aphis gossypii, and Macrosiphum euphorbiae, the most abundant. During the autumn, C. fragaefolli and M. euphorbiae were scarce and A. gossypii was denser on mature leaves, while during summer M. euphorbiae was absent. During the winter, C. fragaefolii predominated on buds and young leaves, A. gossypii on flowers, and both species on mature leaves. During the spring, C. fragaefolii was even more abundant on buds, A. gossypii predominated on mature leaves, and the three species were equally abundant on flowers and young leaves. Parasitoids emerged from A. gossypii, M. euphorbiae and Myzus persicae, but not from C. fragaefolii. Three Aphidius and two Aphelinus species were recovered. All primary parasitoid species emerged from A. gossypii, and secondary parasitoids emerged only from this aphid. Aphis gossypii parasitism on mature leaves was markedly higher in winter and summer than in autumn and spring. Parasitism of A. gossypii was independent of its density, and the number of parasitized aphids was never higher than six. Our results contribute to define the most appropriate sample unit to estimate aphid density of different species and provide information about seasonal natural parasitism.

    • Authors: Aye T. Win; Tetsu Kinoshita; Kazuki Tsuji
      Abstract: The mutualistic association between ants and hemipterans is often facultative and can be affected by the availability of other food sources. In the present study we tested whether the tending behavior of the big-headed ant, Pheidole megacephala (Fabricius), had a negative impact on the pink pineapple mealybug, Dysmicoccus brevipes (Cockerell), when alternative food sources: (1) sugar solution, (2) purified water + mealworms and (3) sugar solution + mealworms versus with purified water (control) were provided to the ant colonies. We found that the frequency of ant tending on D. brevipes decreased when ants were provided with alternative food sources. However, we did not see any aggressive behaviors and predation of ants on D. brevipes. Also, the survival of D. brevipes was not different among food condition treatments. These results suggest that the decreased tending frequency of ants can lead to the decline in ant protection service to mealybugs.

    • Authors: Tanzila Afrin; Asuka Kounosu; Mohammad-Masum Billah; Kazunori Murase; Taisei Kikuchi
      Abstract: Studies on host-associated microbial communities using faecal samples has been providing important insights into the health, ecology and evolution of various animals. Many gut microbiome studies currently use manual kit-based DNA extraction methods, yet new methods that allow high-throughput sample processing are in demand. In this study, we evaluated magnetic cellulose bead-based DNA extraction methods, which can be automated in a work station, using mouse, Mus musculus (Linnaeus), and bovine, Bos taurus (Linnaeus), faeces as a model. Our data showed that those methods can provide good quantity and quality of extracted DNA suitable for 16S-rRNA-based microbiome analyses for a wide variety of samples, comparable to or more efficiently than the widely used standard method. The automated extraction requires less time and fewer manual steps, which makes these methods suitable for high-throughput faecal microbiome analyses.

      Abstract: Diet mixing is a common feeding habit among polyphagous insect herbivores and is believed to be advantageous for performance-related factors like growth, survival and oviposition. However, relatively little is known about the influence of artificial diet or their mixtures on the performance of edible insects. We examined the effects of artificial diet mixtures on the developmental and reproductive performance (survival, developmental time, fresh adult weight and female fecundity) of an edible grasshopper, Ruspolia differens (Orthoptera: Tettigoniidae). We raised individuals from eggs and reared newly hatched nymphs to adult stage on six different dietary treatments consisting of a single diet, and mixtures of two, three, five, six and eight artificial diets. More diversified diets resulted in shorter development time and greater adult fresh weight and female fecundity compared to the single diet or less diversified diets. Even with slight diet diversification, survival to adult stage was greatly improved. Overall, these results highlight the potential of diet mixtures in achieving maximum adult weights and female fecundity and shortening development time, information which could be used when designing mass-rearing programs for this edible grasshopper.

      Abstract: The edible grasshopper Ruspolia differens (Orthoptera: Tettigoniidae) gathered seasonally from the wild is a highly valued and an economically important edible insect, particularly in East Africa. To reduce the pressure on wild populations, a sustainable mass production technique needs to be developed. Unfortunately, however, basic biological know-how on feeding habits of R. differens is poorly understood, which poses a constraint on the development of mass-rearing technology. Here, we evaluated the acceptance and feeding preference of R. differens for 16 cultivated or processed foods using no-choice and multiple-choice laboratory bioassays. The results indicated that adult R. differens can eat a wide variety of foods but does not necessarily accept all the foods equally. Furthermore, our experiments showed that R. differens has high ability to select diet among those available. The order of decreasing preference was wheat bran > germinated finger millet > rice seed head > finger millet seed head > chicken feed egg booster > sorghum seed head. Finally, our study indicated that sex and color morph are not associated with the order of acceptance and preference of diets in R. differens. These results show potential foods that could be utilized for developing future mass-rearing methods for R. differens.

  • In vitro analysis of DIMBOA catabolism in the Asian corn borer Ostrinia
           furnacalis (Lepidoptera: Crambidae)
    • Authors: Tran Thi Thu Phuong; Masanobu Yamamoto; Takashi Matsuo; Takeshi Fujii; Yukio Ishikawa
      Abstract: Larvae of the Asian corn borer Ostrinia furnacalis (Guenée) must cope with 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA), a major toxic allelochemical present in its host plant, maize Zea mays L. UDP-glucosyltransferase (UGT), which conjugates glucose to various lipophilic toxic compounds and thereby makes them more hydrophilic for easier excretion, has been suggested to be involved in the detoxification of DIMBOA in several insects. Our previous in vitro assays using O. furnacalis midgut homogenates demonstrated that DIMBOA was catabolized only when UDP-glucose, a glucose donor for UGT activity, was included in the reaction mixture; however, DIMBOA glucoside, the expected product of UGT activity, was only detected in trace amounts in assay products. The present study revealed that DIMBOA glucoside was produced, but was immediately degraded by unidentified enzymes in the midgut homogenate that do not require UDP-glucose for their activities, suggesting the presence of a novel route for DIMBOA catabolism in O. furnacalis.

  • Potency of the mosquitocidal Cry46Ab toxin produced using a 4AaCter-tag,
           which facilitates formation of protein inclusion bodies in Escherichia
    • Authors: Tomoaki Okazaki; Junya Ichinose; So Takebe; Toru Ide; Tohru Hayakawa
      Abstract: A Cry46Ab toxin derived from Bacillus thuringiensis strain TK-E6 shows mosquitocidal activity against Culex pipiens pallens Coquillett (Diptera: Culicidae) larvae as well as preferential cytotoxicity against human cancer cells. In B. thuringiensis cells, Cry46Ab is produced and accumulates as a protein crystal that is processed into the active 29-kDa toxin upon solubilization in the alkaline environment of the insect midgut. The Cry46Ab protoxin is 30 kDa, and is therefore thought to require an accessory protein such as P20 and/or ORF2 for efficient crystal formation. In the present study, the potency of the 4AaCter-tag was investigated for the production of alkali-soluble inclusion bodies of recombinant Cry46Ab in Escherichia coli. The 4AaCter-tag is a polypeptide derived from the C-terminal region of the B. thuringiensis Cry4Aa toxin and facilitates the formation of alkali-soluble protein inclusion bodies in E. coli. Fusion with the 4AaCter-tag enhanced both Cry46Ab production and the formation of Cry46Ab inclusion bodies. In addition, upon optimization of protein expression procedures, the Cry46Ab–4AaCter inclusion bodies showed mosquitocidal activity and stability in aqueous environments comparable to Cry46Ab without the 4AaCter-tag. Our study suggests that use of the 4AaCter-tag is a straightforward approach for preparing formulations of smaller-sized Cry toxins such as Cry46Ab in E. coli.
