Host –pathogen interaction after infection of Galleria mellonella with the filamentous fungus Beauveria bassiana
AbstractThe filamentous fungusBeauveria bassiana is a natural pathogen of the greater wax mothGalleria mellonella. Infection with this fungus triggered systemic immune response inG. mellonella; nevertheless, the infection was lethal if spores entered the insect hemocel. We observed melanin deposition in the insect cuticle and walls of air bags, while the invading fungus interrupted tissue continuity. We have shown colonization of muscles, air bags, and finally colonization and complete destruction of the fat body —the main organ responsible for the synthesis of defense molecules in response to infection. This destruc...

The endoparasitoid Psyllaephagus arenarius benefits from ectoparasitic venom via multiparasitism with the ectoparasitoid Tamarixia lyciumi
AbstractAs solitary nymphal parasitoids ofParatrioza sinica, the ectoparasitoidTamarixia lyciumi and the endoparasitoidPsyllaephagus arenarius act as effective biocontrol agents. Thus, it is necessary to facilitate mass productions of both species. Despite showing an excellent parasitic ability,Ps. arenarius is often trapped fatally inside 5th ‐instar nymphs ofPa. sinica due to strong host immunity. To improve the emergence rate ofPs. arenarius, we evaluated whetherPs. arenarius could utilizeT. lyciumi venom via multiparasitism, so the parasitism characteristics of both species were examined between separate ‐existence...

BmSd gene regulates the silkworm wing size by affecting the Hippo pathway
In this study, the function ofBmSd which has been characterized as one of the Hippo ‐pathway‐related genes was analyzed for silkworm wing development. We found thatmats,warts, andhippo expression levels were higher in u11 compared to p50 wing discs.BmSd (scalloped) expression, which encodes a prominent transcriptional partner to Yorkie (Yki), gradually decreased during the wandering stage in u11, but exhibited the opposite expression pattern in p50. WhenBmSd was knocked down by small interfering RNA during the wandering stage in the p50 strain, 57.9% of the individuals showed minute wings. Additionally,ex,kibra, andwin...

What do we know about biological nitrogen fixation in insects? Evidence and implications for the insect and the ecosystem
AbstractMany insects feed on a low ‐nitrogen diet, and the origin of their nitrogen supply is poorly understood. It has been hypothesized that some insects rely on nitrogen‐fixing bacteria (diazotrophs) to supplement their diets. Nitrogen fixation by diazotrophs has been extensively studied and convincingly demonstrated in termit es, while evidence for the occurrence and role of nitrogen fixation in the diet of other insects is less conclusive. Here, we summarize the methods to detect nitrogen fixation in insects and review the available evidence for its occurrence (focusing on insects other than termites). We distingu...

Co ‐infection of Wolbachia and Spiroplasma in spider mite Tetranychus truncatus increases male fitness
In this study, we explored the influence of the two symbionts on male mite host fitness and used RNA sequencing to generate the transcriptomes ofT. truncatus with four different types of infection. In total, we found symbiont ‐infected lines had a higher hatch proportion than the uninfected line, and the development time of the uninfected line was longer than that of the other lines. Co‐infection changed the expression of many genes related to digestion detoxification, reproduction, immunity and oxidation reduction.

Diversity and seasonal variation of ground and understory spiders from a tropical mountain cloud forest
AbstractWe made intensive samplings to study the seasonal response of spiders across different forest strata (ground and understory) in a tropical mountain cloud forest from Mexico. We sampled spiders from ten plots in six sampling events during the dry and rainy season, to analyze their abundance, structure (distribution of abundance among species), diversity and the response of the five dominant species at each stratum. Results demonstrated that seasonal patterns of spider communities differed among strata, revealing a complex spatiotemporal dynamic. Abundance, structure, diversity of ground spiders, as well as the respo...

MicroRNA ‐2738 regulates gene expression in the sex determination pathway in Bombyx mori
AbstractMicroRNAs (miRNAs) are a class of short, non ‐coding transcripts that bind to 3′‐untranslated regions to trigger messenger RNA degradation or translational inhibition. Here we explored how miRNAs regulate sex determination inBombyx mori, a lepidopteran model insect. Genes known to be involved in sex determination,BmPSI,Bmdsx, andBmMasc, are predicted targets of the species ‐specific miR‐2738. Using a dual luciferase reporter assay in HEK293T cells, we confirmed that miR‐2738 suppressed transcription ofBmPSI,Bmdsx, andBmMasc. The levels ofBmPSI andBmMasc were significantly down ‐regulated inB. mori...

Identification of the ryanodine receptor mutation I4743M and its contribution to diamide insecticide resistance in Spodoptera exigua (Lepidoptera: Noctuidae)
In this study, we identified one of the known RyR target site resistance mutations (I4790M) in a field ‐collected population ofSpodoptera exigua. The field ‐collected WF population ofS. exigua exhibited 154 fold resistance to chlorantraniliprole when compared with the susceptible WH ‐S strain. Sequencing the transmembrane domains ofS. exigua RyR (SeRyR) revealed that the resistant WF strain was homozygous for the I4743M mutation (corresponding to I4790M in PxRyR), whereas the G4900E allele (corresponding to G4946E of PxRyR) was not detected. The 4743M allele was introgressed into the susceptible WH ‐S strain by cro...

Female competition for availability of males in insects: the Nezara viridula (Linnaeus, 1758) model
AbstractMultimodal communication in solitary stinkbugs enables them to meet, mate and copulate. Many plant ‐dwelling species exchange information during the calling phase of mating behavior using substrate‐borne vibratory signals. A female‐biased gender ratio induces rivalry and competition for a sexual partner. Female competition for males, first described among Heteroptera in three stinkbug speci es, revealed species specific differences and opened the question of plasticity in individually emitted temporal and frequency signal characteristics during calling and rival alternation. To address this question and gain ...

Behavioral evidence for contextual olfactory ‐mediated avoidance of the ubiquitous phytopathogen Botrytis cinerea by Drosophila suzukii
In this study adults ofDrosophila suzukii Matsumura, an invasive larval frugivore, showed reduced attraction to the odor of raspberry fruit, a food tissue, when infected withBotrytis cinerea Pers., a ubiquitous phytopathogen, in favor of odors of uninfected raspberry fruit. Moreover,D. suzukii oviposited fewer eggs on infected raspberry fruit relative to uninfected raspberry fruit. Larval survival and adult size after eclosion were significantly reduced when reared onB. cinerea ‐infected raspberry relative to uninfected fruit. Interestingly, when the behavioral choice experiment was repeated usingBotrytis ‐infected vs....

Identification of a PP2A gene in Bombyx mori with antiviral function against B. mori nucleopolyhedrovirus
AbstractSer/Thr protein phosphatase 2A (PP2A) is one of the type 2 protein phosphatases, which is required for many intracellular physiological processes and pathogen infection. However, the function of PP2A is unclear in silkworm,Bombyx mori. Here, we cloned and identifiedBmPP2A, aPP2A gene fromB. mori, which has two HEAT domains and a high similarity to PP2A from other organisms. Our results showed that BmPP2A is localized in the cytoplasm and highly expressed in silkworm epidermis and midgut, and thatBombyx mori nucleopolyhedrovirus (BmNPV) infection induces down ‐regulation of BmPP2A expression. Furthermore, up‐reg...

AbstractContinuous jumping behavior, a kind of endurance locomotion, plays important roles in insect ecological adaption and survival. However, the methods used for the efficient evaluation of insect jumping behavior remain largely lacking. Here, we developed a locomotion detection system named JumpDetector with automatic trajectory tracking and data analysis to evaluate the jumping of insects. This automated system exhibits more accurate, efficient, and adjustable performance than manual methods. By using this automatic system, we characterized a gradually declining pattern of continuous jumping behavior in 4th ‐instar ...

Molecular and functional characterization of three odorant ‐binding proteins from the wheat blossom midge, Sitodiplosis mosellana
AbstractSitodiplosis mosellana, a periodic but devastating wheat pest, relies on wheat spike volatiles as a cue in selecting hosts for oviposition. Insect odorant ‐binding proteins (OBPs) are thought to play essential roles in filtering, binding and transporting hydrophobic odorant molecules to specific receptors. To date, the molecular mechanisms underlyingS. mosellana olfaction are poorly understood. Here, threeS. mosellana antenna ‐specificOBP genes,SmosOBP11,16 and21, were cloned and bacterially expressed. Binding properties of the recombinant proteins to 28 volatiles emitted from wheat spikes were investigated usi...

Identification of two clip domain serine proteases involved in the pea aphid's defense against bacterial and fungal infection
In this study, we identified five clip domain serine proteases in the pea aphids. The messenger RNA levels of two of them, Ap_SPLP and Ap_VP, were upregulated by Gram ‐positive bacteriumStaphylococcus aureus and fungusBeauveria bassiana infections. Double ‐stranded RNA‐based expression knockdown of these two genes resulted in reduced PO activity of the aphid hemolymph, higher loads ofS. aureus andB. bassiana in the aphids, and lower survival rates of the aphids after infections. Our data suggest that Ap_SPLP and Ap_VP are involved in PPO activation pathway in the pea aphid. (Source: Insect Science)
