Silencing of odorant binding protein gene AlinOBP4 by RNAi induces declining electrophysiological responses of Adelphocoris lineolatus to six semiochemicals
Abstract Odorant binding proteins (OBPs) are believed to be important for transporting semiochemicals through the aqueous sensillar lymph to the olfactory receptor cells within the insect antennal sensilla. Here, we injected AlinOBP4‐siRNA into the conjunctivum between prothorax and mesothorax of the lucerne plant bug, Adelphocoris lineolatus and evaluated the silencing of AlinOBP4 by reverse transcription polymerase chain reaction (RT‐PCR) analysis, quantitative real‐time PCR (qPCR) test and electroantennogram (EAG) assay. The combination of RT‐PCR and qPCR analyses revealed that the levels of messenger RNA transc...

Honey bees are valuable for agriculture economy and important contributes to ecosystem services due to that they are the most efficient and economic pollinators. However honeybees are facing huge challenges due to degradation of vegetation, and due to honeybee pests and diseases. Apis mellifera syriaca exhibits a high degree of tolerance to pests and pathogens including varroa mites. This native honey bee subspecies of Jordan and most of the Levant region is expresses behavioral adaptations to high temperature and dry seasons typical of the region. Using the next‐generation sequencing (NGS) technology some genetic factor...

Metatranscriptome of the protistan community in Reticulitermes flaviceps
In this study, we used the juvenile hormone analog fenoxycarb to induce termite workers (Reticulitermes flaviceps) to differentiate into pre‐soldiers. A metatranscriptomic investigation of the protistan community was then performed by 454 pyrosequencing. From a thorough analysis based on 597 312 generated reads, we found that the starch and sucrose metabolism pathway was the most abundant pathway across the metatranscriptome. The current study demonstrates that the metatranscriptome of the protistan community in termites contains an abundance of lignocellulase, which plays a vital role in termite nutrition.

Pheromone ‐trapping the nun moth, Lymantria monacha (Lepidoptera: Lymantriidae) in Inner Mongolia, China
Abstract The nun moth, Lymantria monacha L., is one of the most important defoliators of Eurasian coniferous forests. Outbreaks during 2011–2015 in the natural/planted larch, and larch‐birch mixed forests of the Greater Khingan Range in Inner Mongolia, China, caused tremendous timber losses from severe defoliation and tree mortality. A series of trapping experiments were conducted in these outbreak areas to evaluate the efficacy of a synthetic species‐specific pheromone lure based on the female pheromone blend of European nun moth populations. Our results clearly show that the nun moth in Inner Mongolia is highly...

Cuticular protein LmTwdl1 is involved in molt development of the migratory locust
Abstract The cuticle, an essential structure for insects, is produced from cuticular proteins and chitin via a series of biochemical reactions. Tweedle genes are important members of the cuticular protein family and have four conserved motifs binding to chitin. Tweedle family genes have been found to play a profound effect on cuticle development. Here, we report that the cuticular protein gene LmTwdl1 of Locusta migratoria belongs to the Tweedle family. In situ hybridization showed that LmTwdl1 is localized to epidermal cells of the cuticle. The expression patterns of LmTwdl1 showed low expression in the cuticle during the...

Comparative morphometric and chemical analyses of phenotypes of 2 invasive ambrosia beetles (Euwallacea spp.) in the United States
Abstract The polyphagous shot hole borer (PSHB), Euwallacea sp., was first detected in 2003 in Los Angeles County, California, USA. Recently, this invasive species has become a major pest of many hardwood trees in urban and wildland forests throughout southern California. PSHB is nearly identical in morphology and life history to the tea shot hole borer (TSHB), Euwallacea fornicatus, an invasive pest of hardwoods in Florida, USA and many other parts of the world. However, molecular studies have suggested that the taxa are different species. We conducted morphometric and chemical analyses of the phenotypes of Euwallacea sp....

Transgenic cotton expressing CYP392A4 double ‐stranded RNA decreases the reproductive ability of Tetranychus cinnabarinus
Abstract As a polyphagous pest, Tetranychus cinnabarinus has the ability to overcome the defense of various hosts, and causes severe losses to various economically important crops. Since the interaction between pest and host plants is a valuable clue to investigate potential ways for pest management, we intend to identify the key genes of T. cinnabarinus for its adaption on cotton, then, with RNA interference (RNAi) and transgenic technology, construct a transgenic cotton strain to interfere with this process, and evaluate the effect of this method on the management of the mites. The difference of gene expression of T. cin...

Cumulative effects of volcanic ash on the food preferences of 2 Orthopteran species
Abstract Inert dusts are an early form of insecticide which is still in use. One of the most common inert dusts is volcanic ash. In order to study the reaction of rangeland grasshoppers, Dichroplus vittigerum (Acrididae) and a katydid, Burgilis mendosensis (Phaneropteridae), to the presence of volcanic ash in their food sources and how this reaction changed as a function of time, we conducted paired preference tests between clean leaves of their preferred host plant and leaves exposed to volcanic ash of different grain size. The behavioral response was measured as the rating on the Thurstonian preference scale of leaves wi...

Vespa velutina nest distribution at a local scale: An 8 ‐year survey of the invasive honeybee predator
Abstract Vespa velutina is an invasive species that was observed for the first time in France and Europe in 2004, which rapidly threatened domestic honeybees with active predation. For the first time in this study, we analyzed the distribution of V. velutina nests at a local scale to understand the pattern of nesting, and in 8 years of monitoring, a total of 528 nests were surveyed. With the exception of 2 years, the nests of V. velutina were randomly distributed within the monitored area, which suggested that intraspecific competition for nesting sites and/or food was unlikely. When the data for all years were combined, a...

The brown planthopper (BPH), the most serious rice insect pest in Asia, is monophagous and feeds only on the phloem sap of the rice plant. Microbial endosymbionts of BPH, including yeast‐like endosymbionts and bacterial endosymbionts, play important roles in insect‐plant competition, thereby facilitating the BPH's adaptation to its rice host. To better understand the interactions of microbe‐insect‐plant, a detailed description of the genomic features of the bacterial endosymbiont, Arsenophonus nilaparvatae, was provided in this issue (see pages 478‐486).

Large ‐scale gene expression reveals different adaptations of Hyalopterus persikonus to winter and summer host plants
In this study, the molecular mechanism of host alternation was explored through a large‐scale gene expression analysis of the mealy aphid Hyalopterus persikonus on winter and summer host plants. More than four times as many unigenes of the mealy aphid were significantly upregulated on summer host Phragmites australis than on winter host Rosaceae plants. In order to identify gene candidates related to host alternation, the differentially expressed unigenes of H. persikonus were compared to salivary gland expressed genes and secretome of Acyrthosiphon pisum.

Recombinant Helicoverpa armigera nucleopolyhedrovirus with arthropod ‐specific neurotoxin gene RjAa17f from Rhopalurus junceus enhances the virulence against the host larvae
Abstract A recombinant Helicoverpa armigera nucleopolyhedrovirus (HearNPV) expressing the insect‐selective neurotoxin (RjAa17f) from Cuban scorpion Rhopalurus junceus was constructed by replacing the UDP‐glucosyltransferase gene (egt) using λ‐red homologous recombination system. Another egt deleted control HearNPV was constructed in a similar way by inserting egfp gene into the egt locus. One‐step viral growth curve and viral DNA replication curve analysis confirmed that the recombination did not affect the viral growth and DNA replication in host cells.
