  • External morphology of the leaf-tying larva and pupa of the Neotropical
           micromoth Eccopsis razowskii (Lepidoptera: Tortricidae)
    • Authors: Marcelo Vargas-Ortiz; Luis E. Parra; Héctor A. Vargas
      Pages: 19 - 27
      Abstract: Abstract Eccopsis razowskii Vargas (Lepidoptera: Tortricidae: Olethreutini) is a Neotropical micromoth native to the Atacama Desert with leaf-tying larvae that feed on Acacia macracantha Willd. (Fabaceae). The external morphology of its last instar and that of its pupa are described and illustrated for the first time with the aid of light and scanning electron microscopy. The morphology of each of these life stages is highly similar to that of the only sympatric congeneric, the pest species E. galapagana Razowski & Landry, the larvae of which feed on Prosopis spp. (Fabaceae). The pupae of the two species cannot be separated based on morphology; they can only be accurately separated based on the form of the mandible. The findings are discussed in terms of their significance for the taxonomy and systematics of Eccopsis. In addition, a comparison with the two other Tortricidae associated with A. macracantha in the Atacama Desert is provided.

  • Bacillus thuringiensis Cry11Ba works synergistically with Cry4Aa but not
           with Cry11Aa for toxicity against mosquito Culex pipiens (Diptera:
           Culicidae) larvae
    • Authors: Tohru Hayakawa; Naoya Yoneda; Kouji Okada; Ayuko Higaki; Mohammad Tofazzal Hossain Howlader; Toru Ide
      Pages: 61 - 68
      Abstract: Abstract A 2,175-bp modified gene (cry11Ba-S1) encoding Cry11Ba from Bacillus thuringiensis subsp. jegathesan was designed and the recombinant protein was expressed as a fusion protein with glutathione S-transferase in Escherichia coli. The recombinant Cry11Ba was highly toxic against Culex pipiens mosquito larvae, being nine and 17 times more toxic than mosquitocidal Cry4Aa and Cry11Aa from Bacillus thuringiensis subsp. israelensis, respectively. Interestingly, a further increase in the toxicity of the recombinant Cry11Ba was achieved by mixing with Cry4Aa, but not with Cry11Aa. These findings suggested that Cry11Ba worked synergistically with Cry4Aa, but not with Cry11Aa, in exhibiting toxicity against C. pipiens larvae. On the other hand, the amount of Cry toxin bound to brush border membrane vesicles (BBMVs) did not significantly change between individual toxins and the toxin mixtures, suggesting that the increase in toxins binding to BBMVs was not a reason for the observed synergistic effect. It is generally accepted that synergism of toxins is a potentially powerful tool for enhancing insecticidal activity and managing Cry toxin resistance in mosquitoes. The mixture of Cry4Aa and Cry11Ba in order to increase toxicity would be very valuable in terms of mosquito control.

  • Effects of a mud snail Cipangopaludina chinensis laeta (Architaenioglossa:
           Viviparidae) on the abundance of terrestrial arthropods through rice plant
           development in a paddy field
    • Authors: V. K. Dewi; S. Sato; H. Yasuda
      Pages: 97 - 106
      Abstract: Abstract The effects of a mud snail, Cipangopaludina chinensis laeta (Martens) (Architaenioglossa: Viviparidae), on terrestrial arthropods through rice plant development in a paddy field were investigated in 2013 and 2014 by a field experiment. There were no significant differences between treatments in the abundance of aquatic organisms, which comprised several functional feeding groups in both years. The presence of mud snails did not significantly affect plant height and soil plant analysis development values, either, except in June 2014, when tiller number and biomass of the rice plants tended to be larger in plots with snails versus those without. Significantly higher abundances of terrestrial organisms, including phytophagous pest insects and other insects, but not natural enemies of the pest insects, occurred in plots with snails. As shown by principal component analysis, the community structure of the terrestrial organisms was significantly different between the two treatments in both years. The results of this study indicate that mud snails play an important role in the paddy field ecosystem, in which they influence the biomass production of rice plants and the abundance of organisms in terrestrial ecosystems through direct and indirect interactions at different trophic levels.

  • The number of stripes on the compound eyes reflects each instar in
           Acromantis satsumensis (Mantodea: Hymenopodidae)
    • Authors: Hiroshi Nakamine; Kazuhisa Yamasaki; Hideshi Naka
      Pages: 135 - 138
      Abstract: Abstract The praying mantis genus Acromantis is characterized by its compound eyes with stripe patterns in the Japanese Mantodea. In the laboratory, we observed that the 1st instar nymphs of Acromantis satsumensis Matsumura had a single stripe on their compound eyes, and one more stripe appeared on both of their compound eyes when they became 2nd instar nymphs. Likewise, the 3rd instars had 3 stripes, the 4th instars had 4 stripes, and so on. These results suggest that the stripe patterns on the compound eyes increase one by one with each molt in A. satsumensis.

  • Characterization of 14 polymorphic microsatellite loci developed for an
           Afrotherian species endemic to southern Africa, Elephantulus myurus
           (Macroscelidea: Macroscelididae)
    • Authors: Sasha Hoffmann; Heather J. Webster; Peter R. Teske; Heike Lutermann; Nigel C. Bennett; Bettine Jansen van Vuuren
      Pages: 139 - 145
      Abstract: Abstract Fourteen microsatellite loci were developed for the eastern rock sengi, Elephantulus myurus Thomas & Schwann, 1906 by incorporating genetic diversity from across its range in South Africa. Sengis are small mammals belonging to the order Macroscelidea, which comprises 19 species, all of which are endemic to Africa. The loci were amplified in 66 individuals from six localities. An average of 10.5 alleles per locus were identified, with observed and expected heterozygosity values ranging from 0.081 to 0.909 and 0.404 to 0.911, respectively. We also investigated cross-species amplification within the family and found variation in amplification success for five different species. The preliminary results from these amplification efforts could aid further studies into aspects of species diversity and biology. The markers described here represent the first set of variable nuclear markers for the genus Elephantulus, and together with a set of 8 recently developed markers for Rhynchocyon petersi, Bocage 1880, the first markers for the order Macroscelidea.

  • Molecular diagnostics of the R81T mutation on the D-loop region of the β
           1 subunit of the nicotinic acetylcholine receptor gene conferring
           resistance to neonicotinoids in the cotton aphid, Aphis gossypii

      Abstract: Abstract Aphis gossypii Glover is a cosmopolitan and polyphagous aphid species. When neonicotinoid-resistant clones of A. gossypii were recently found in Japan, it was subsequently discovered that a point mutation (R81T) in the D-loop region of the β1 subunit of the nicotinic acetylcholine receptor gene had conferred this resistance. To quickly identify this neonicotinoid-resistant allele, we developed a molecular diagnostics test using a multiplex polymerase chain reaction method that targeted the R81T mutation.

  • Suppression of population growth of the Japanese mealybug, Planococcus
           kraunhiae (Hemiptera: Pseudococcidae), by using an attractant for
           indigenous parasitoids in persimmon orchards
    • Authors: Mayumi Teshiba; Jun Tabata
      Pages: 153 - 158
      Abstract: Abstract We previously reported that two parasitic wasps, Anagyrus sawadai Ishii and Leptomastix dactylopii Howard, are strongly attracted to (2,4,4-trimethyl-2-cyclohexenyl)methyl butyrate (cyclolavandulyl butyrate, CLB), a cyclization product of the sex pheromone of the Japanese mealybug, Planococcus kraunhiae (Kuwana). These wasps attacked more P. kraunhiae in the presence of CLB in our field experiments. In the present study, we showed that these CLB-attracted wasps parasitized and suppressed the mealybug population increase in field persimmon orchards, which would lead to reducing mealybug damage on commercial products. Although many attractants for natural enemies are reported, compounds such as CLB that suppress pest population growth in fields are scarce. Moreover, to the best of our knowledge, this is currently the only example to demonstrate that the “non-natural” enemy that does not typically attack the pest under natural conditions can be enrolled in biological control by using its attractant.

  • Invasion dynamics of Asian hornet, Vespa velutina (Hymenoptera: Vespidae):
           a case study of a commune in south-west France
    • Authors: Daniel N. Franklin; Mike A. Brown; Samik Datta; Andrew G. S. Cuthbertson; Giles E. Budge; Matt J. Keeling
      Abstract: Abstract Asian hornet, Vespa velutina Lepeletier nests were discovered in 2007 in Andernos-les-Bains on the south-west coast of France, 3 years after the first reported sightings in France. The number of nests increased in the commune over the following 7 years, despite local authorities enacting a destruction policy. The nests existed in close proximity to one another leading to a high density of over 10 nests per square kilometre in urban areas. New information on the chosen habitat for nests is presented, and the differences between primary and secondary locations are evident, with primary nests mostly occupying buildings and man-made structures, while secondary nests were found on trees. Using Bayesian inference methods, we fit a basic model to the observational data, which allows us to estimate key demographic parameters. This model fit is highly informative for predicting V. velutina spread and colonisation of other at-risk regions, and suggests that local control has a limited impact on the spread of V. velutina once established within a region.

  • Soldiers are differentiated from male larval stages in incipient colonies
           of Nasutitermes takasagoensis (Isoptera: Termitidae)
    • Authors: Kouhei Toga; Chieka Minakuchi; Kiyoto Maekawa
      Abstract: Abstract In phylogenetically ancestral taxa of termites (the so-called lower termites), at least one soldier emerges and is maintained longitudinally in each incipient colony. However, in apical taxa (the so-called higher termites), the developmental pathway and regulation of soldiers in incipient colonies currently remain unknown. We therefore examined soldier and worker development in incipient colonies of higher termites (Nasutitermes takasagoensis Shiraki). Developmental stages and castes were successfully discriminated by head width in incipient colonies 4 months after colony foundation. Furthermore, differences were observed in the number of bristles on antennae between first- and second-instar larvae. In N. takasagoensis, there was more than one soldier in each incipient colony 4 months after its foundation. Presoldiers in the incipient colonies were differentiated from an earlier instar (male second-instar larvae), whereas, in mature colonies, they were differentiated from male third instars (= minor workers). The developmental period of the former (7 days) was markedly shorter than that of the latter (14 days). All female second-instar larvae molted into workers. The developmental processes shown here are useful for obtaining a clearer understanding of the mechanisms of soldier/worker differentiation in higher termites.

           green bugs, Plautia stali (Heteroptera: Pentatomidae), using male flower
           production of sugi, Cryptomeria japonica (Pinales: Cupressaceae), and

    • Authors: Toru Ohtani; Tosaku Mihira; Toshiyuki Kawana; Shigeki Fukushima; Ken Shimizu
      Abstract: Abstract The abundance of the adult brown-winged green bug, Plautia stali Scott, varies annually. During outbreaks, P. stali causes severe damage to various fruit crops. Therefore, predicting its abundance beforehand is important. In this study, we constructed multiple regression models to predict the abundance of overwintered adult P. stali in Chiba Prefecture, Japan, by using the accumulated aggregation-pheromone-trap captures of P. stali and the male flower production of sugi Cryptomeria japonica (Thunb. ex L.f.) D. Don, which relates to cone production, from 1998 to 2016. The abundance of overwintered adults in the present year can be predicted by male C. japonica flower production and the abundance of P. stali adults in the previous year. The models are highly precise and can calculate estimates in August for the abundance in the next year, which is far enough in advance for the application of control measures. These models also indicate intraspecific competition for food resources in P. stali.

  • Do the amount of sex pheromone and frequency of calling behavior in
           females affect the mate-searching behavior of males in Dasylepida
           ishigakiensis (Coleoptera: Scarabaeidae)'
    • Authors: Hiroe Yasui; Nao Fujiwara-Tsujii; Seiji Tanaka; Sadao Wakamura; Norio Arakaki
      Abstract: Abstract The white grub beetle Dasylepida ishigakiensis Niijima et Kinoshita (Coleoptera: Scarabaeidae) is a serious sugarcane pest on the Miyako Islands, Okinawa, Japan. Because this beetle stays underground for most of its lifetime, mating disruption using a synthetic sex pheromone has been suggested as a promising control measure. The amount of pheromone (2-butanol) released by the females is known to decrease drastically as they repeat calling each day. In this study, we determined the response of males to different concentrations of (R)-2-butanol, both in the laboratory and in the field. Males showed typical pre-mating behaviors and they were attracted to (R)-2-butanol even at a concentration 1/100 of the amount typically emitted by a female during the 1st period of calling. We examined whether female attractiveness to males was reduced with the frequency of calling, by counting the number of males attracted to females that had called during zero to five periods beforehand. Our results indicated that a high level of female attractiveness was maintained even after three periods of calling. Based on these findings, we propose that releasing synthetic sex pheromone shortly before the start of the mating season and into the late mating season may be optimal for disrupting the mating of this beetle.

  • Invasion of Japan by exotic leafminers Liriomyza spp. (Diptera:
           Agromyzidae) and its consequences
    • Authors: Yoshihisa Abe
      Abstract: Abstract Identifying patterns and causes of species displacement is important from the viewpoints of ecology and evolutionary biology as this phenomenon affects community structure. Here I review the species displacement between Liriomyza trifolii (Burgess) and Liriomyza sativae Blanchard (Diptera: Agromyzidae) in Japan. These two species and Liriomyza huidobrensis (Blanchard) originated from the New World and are considered to have invaded Japan from around 1990 to the early 2000s. During this period, L. trifolii was apparently displaced by L. sativae, but the direction of displacement in Japan has been contrary to that observed between the same two species in the USA and China. While the displacement of L. sativae by L. trifolii in these two countries can be attributed to the lower insecticide susceptibility of L. trifolii there, species displacement in the opposite direction in Japan is probably due to the relatively high fecundity of L. sativae and differential effects of the introduced parasitoid Dacnusa sibirica Telenga (Hymenoptera: Braconidae) on both Liriomyza species, except in the south of the country.

  • Trypsinized Cry1Fa and Vip3Aa have no detrimental effects on the adult
           green lacewing Chrysopa pallens (Neuroptera: Chrysopidae)
    • Authors: Intazar Ali; Shuai Zhang; Muhammad Iqbal; Samina Ejaz; Jin-jie Cui
      Abstract: Abstract An exposure bioassay was established for green lacewing Chrysopa pallens (Rambur) (Neuroptera: Chrysopidae) adults using a suitable artificial diet and honey–water solution (20%) to assess the toxicity of trypsinized Cry1Fa and Vip3Aa. Lethal and sub-lethal life table parameters were unaffected after C. pallens adults were given honey–water solutions containing Cry1Fa and Vip3Aa (50 µg/ml) and an artificial diet. In contrast, life table parameters of C. pallens adults were significantly affected when boric acid was mixed with the honey–water solution as a positive control. The uptake, temporal stability and bioactivity of Cry1Fa and Vip3Aa before and after C. pallens access to honey–water were confirmed using double antibody sandwich enzyme-linked immunosorbent assays and a bioactivity verification bioassay. The results prove that trypsinized Cry1Fa and Vip3Aa are safe for C. pallens adults, thus it is speculated that transgenic crops expressing Cry1Fa and Vip3Aa have no detrimental effects on lacewings and are compatible with biological control programs. This study describes a robust experimental design for evaluating the potential toxicity of alkaline gut-activated Bacillus thuringiensis (Bt) proteins on C. pallens adults which can be used to determine the potential toxicity of other Bt proteins on this species.

  • Assessment of genetic diversity and differentiation of Liposcelis

           sequence repeat (ISSR) fingerprinting
    • Authors: En-Tao Sun; Yi-Nan Wang; Kang Wang; Shu-Jun Xu; Dan-Yang Nan; Wen-Jie Chen; Ying-Ying Zhang
      Abstract: Abstract Liposcelis bostrychophila (Psocoptera: Liposcelidae) is a widely distributed pest that can cause considerable economic losses and pose human health risks. Rapid development of insecticide resistance has made L. bostrychophila increasingly difficult to control. To obtain information potentially useful for pest management, genetic diversity and differentiation of L. bostrychophila from five geographic locations in China was studied using inter-simple sequence repeat (ISSR). A total of 104 loci were found by ISSR markers and amplified using 9 selected primers. The percentage of polymorphic bands (PPB) was 91.4%. Shannon’s information index (I) and Nei’s gene diversity (He) indicated high genetic diversity at the species level. Population differentiation (Gst = 0.484) was average in these populations. Analysis of molecular variation (AMOVA) indicated that genetic variation was mainly distributed within populations. Gene flow (Nm = 0.534) was moderate. Cluster analysis showed that genotypes isolated from the same locations displayed higher genetic similarity and permitted the grouping of isolates of L. bostrychophila into three distinct clusters. The correlation between genetic distance and geographic distance was not significant.

      Abstract: Abstract A method to estimate proportions of the G4946E mutation in the ryanodine receptor gene, a major mechanism of diamide insecticide resistance, was developed for Plutella xylostella Linnaeus populations using quantitative sequencing (QS). Using the QS-based method, the relationship between proportions of the G4946E mutation and mortalities for diamide (flubendiamide) was examined using field-collected populations. Results showed that the populations might be classifiable as diamide resistant.

  • Evaluation of easy, non-destructive methods of DNA extraction from minute
    • Authors: Kazuki Miura; Yoshimitsu Higashiura; Kaoru Maeto
      Abstract: Abstract Although it is important to identify species of pest and natural enemy insects in agriculture, morphological identification alone is often difficult. Because a combination of morphological identification and DNA barcoding is very important for identifying indiscriminable species, there is a need to develop non-destructive DNA extraction methods. Here, we compared three general methods of DNA extraction—the Chelex method, PrepMan® Ultra Reagent, and DNeasy® Blood and Tissue Kit—in the search for a rapid, simple, and non-destructive method of DNA extraction from pest and natural enemy specimens. Amplification of PCR production was achieved with the Chelex method and the DNeasy® Blood and Tissue Kit. However, not all specimens tested by the PrepMan® Ultra Reagent method yielded amplification products. Observation of the morphological features of dried Encarsia formosa specimens revealed that all heads and leg segments remained intact after DNA extraction by each of the three methods. Almost all samples treated with the PrepMan® Ultra Reagent method had large, discernible morphological changes, in particular, of the antennae and forewings, which are important features for identifying minute wasps. In contrast, the antennae and forewings of specimens on which we used the Chelex method suffered little damage. Use of the DNeasy® Blood and Tissue Kit method did not alter the forewing features, but strong wrinkles appeared in the antennae. We discuss the DNA extraction techniques from the perspective of these results.

  • The influence of feeding and host deprivation on egg load and reproduction
           of an aphid parasitoid, Aphidius gifuensis (Hymenoptera: Braconidae)
    • Authors: Ming-Zhen Pan; Li Wang; Chen-Yang Zhang; Lin-Xi Zhang; Tong-Xian Liu
      Abstract: Abstract With a view to improving the establishment of Aphidius gifuensis Ashmead, a potential natural enemy for suppression of aphids on vegetables, the effects of host deprivation and honey feeding before release on the parasitoid’s egg load and reproduction were studied under laboratory conditions. Host deprivation significantly affected mummy production and survival rate of female parasitoids. A. gifuensis produced more mummies when exposed to a short period (1 and 2 days) of host deprivation, but when host deprivation lasted for 3 days, their mummy production sharply decreased. Offspring produced by parasitoids that had been deprived of hosts for 2 days were much heavier than those produced by parasitoids deprived of hosts for 1 and 3 days. However, host deprivation did not affect emergence rate or offspring sex ratio; the emergence rate was always above 80%, and the offspring sex ratio was always female biased irrespective of whether the host-deprivation period was 1, 2, or 3 days. Honey feeding greatly increased egg load, longevity and decelerated oosorption of A. gifuensis when hosts were absent, and significantly increased parasitoid mummy production in late age. We discuss the results in the context of augmentative biological control, with the view to understanding how to increase parasitoid performance after they are released.

  • Establishment and yearly/seasonal occurrence of the exotic coccidophagous
           ladybird Cryptolaemus montrouzieri (Coleoptera: Coccinellidae) in citrus
           groves in Shizuoka City, central Japan: a 5-year survey on adult numbers
    • Authors: Shuji Kaneko
      Abstract: Abstract Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) is a ladybird native to Australia, preying on mealybugs and soft scales, and has been utilized worldwide as a biological control agent. It has long been recognized that C. montrouzieri that was introduced into the main island of Japan had failed to become established. The present study monitored yearly and seasonal occurrence of C. montrouzieri adults in citrus groves at Shizuoka Prefectural Fruit Tree Research Center in Shizuoka City, central Japan in 2008–2012 by using sticky traps and beating citrus trees. Adults of C. montrouzieri were continuously captured for 5 and 4 years in a pesticide-free citrus grove and a neighboring reduced-pesticide grove, respectively. Larvae of C. montrouzieri were observed consuming a cottony scale, Pulvinaria aurantii Cockerell, on citrus trees. These results provide unequivocal evidence for the ladybird’s establishment in central Japan. The number of trapped ladybird adults exhibited four peaks a year: in mid-April, early to late June, mid-August, and late September to early October. Adult numbers in each grove varied largely across years, showing a great increase followed by a rapid decline during a period of 4 years. Factors affecting the seasonal/yearly occurrence of C. montrouzieri adults in citrus groves are discussed.

    • Authors: Rachid Hamidi; Philippe Couzi; Khalid Khfif; Didier Rochat
      Abstract: Abstract The invasive red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera: Dryophthoridae) has become the main pest of palms. Because of the cryptic habits of the adult, little is known about the precise movements on palms and the actual dispersal capability in a population. Such data would help to improve risk assessment and management. Miniature radio tags have been increasingly used to monitor movements of animals. In this study, we evaluated the resistance of passive radio frequency identification (RFID) and active radio-transmitters (comprising an antenna) to the burrowing behavior of the insect and their effects on the flight activity. Tagged weevils were placed in boxes filled with fibrous plant material. After 1 week, ca. 90% of insects kept the tag but 83% of the radio-transmitters had a broken antenna. In a screen cage, 100% of insects equipped with RFID flew normally, in contrast to the 17% of insects equipped with active tags. RFID-tagged insects inserted in palm tissue could be easily identified. RFID glued to the thorax affected neither mating behavior nor oviposition. In conclusion, RFID tags appear to be the most efficient tool for tracking the displacement of the weevil in young palms and present new opportunities for promoting studies about gregarious behavior of the red palm weevil on young infected palms.
