Relative importance of long ‐term changes in climate and land‐use on the phenology and abundance of legume crop specialist and generalist aphids
AbstractInsect populations are prone to respond to global changes through shifts in phenology, distribution and abundance. However, global changes cover several factors such as climate and land ‐use, the relative importance of these being largely unknown. Here, we aim at disentangling the effects of climate, land‐use, and geographical drivers on aphid abundance and phenology in France, at a regional scale and over the last 40 years. We used aerial data obtained from suction traps betwe en 1978 and 2015 on five aphid species varying in their degree of specialization to legumes, along with climate, legume crop area and g...

Comparative susceptibility and immune responses of Asian and European honey bees to the American foulbrood pathogen, Paenibacillus larvae
In this study, we examined susceptibility, larval mortality, survival rate and expression of genes encoding antimicrobial peptides (AMPs) includingdefensin,apidaecin,abaecin, andhymenoptaecin inA. mellifera andA. cerana when infected withP. larvae. Our results showed similar effects ofP. larvae on the survival rate and patterns of AMP gene expression in both honey bee species when bee larvae are infected with spores at the median lethal concentration (LC50) forA. mellifera. All AMPs of infected bee larvae showed significant upregulation compared with noninfected bee larvae in both honey bee species. However, larvae ofA. ce...

Discovering genes responsible for silk synthesis in Bombyx mori by piggyBac ‐based random insertional mutagenesis
AbstractSilkworm mutants are valuable resources for both transgenic breeding and gene discovery. PiggyBac ‐based random insertional mutagenesis has been widely used in gene functional studies. In order to discover genes involved in silk synthesis, a piggyBac‐based random insertional library was constructed usingBombyx mori, and the mutants with abnormal cocoon were particularly screened. By this means, a “thin cocoon” mutant was identified. This mutant revealed thinner cocoon shell and shorter posterior silk gland (PSG) compared with the wild type. The messenger RNA (mRNA) levels of all the three fibroin ge...

Intraseasonal asynchrony as a factor boosting isolation within a metapopulation: The case of the clouded apollo
This article discusses the influence of phenology ‐related intraseasonal asynchrony on metapopulation dynamics and stability. As the part played by intraseasonal asynchrony is as yet unclear and poorly described, greater account of it should be taken in both metapopulation research and conservation practice. The subpopulations of theParnassius mnemosyne metapopulation studied here are strongly isolated because of the phenological shift between them, despite the relatively small physical distances between them.  This isolation is the result of a significant temporal shift in the species’ flight periods in ...

Plasticity of mycangia in Xylosandrus ambrosia beetles
AbstractInsects that depend on microbial mutualists evolved a variety of organs to transport the microsymbionts while dispersing. The ontogeny and variability of such organs is rarely studied, and the microsymbiont's effects on the animal tissue development remain unknown in most cases. Ambrosia beetles (Coleoptera: Curculionidae: Scolytinae or Platypodinae) and their mutualistic fungi are an ideal system to study the animal –fungus interactions. While the interspecific diversity of their fungus transport organ—mycangia—is well‐known, their developmental plasticity has been poorly described. To determin...

Dispersing male Parnassius smintheus butterflies are more strongly affected by forest matrix than are females
AbstractDispersal is a central aspect of the ecology, evolution, and conservation of species. Predicting how species will respond to changing environmental conditions requires understanding factors that produce variation in dispersal. We explore one source of variation, differences between sexes within a spatial population network. Here, we compare the dispersal patterns of male and femaleParnassius smintheus among 18 subpopulations over 8 years using the Virtual Migration Model. Estimated dispersal parameters differed between males and females, particularly with respect to movement through meadow and forest matrix habitat...

Sperm limitation affects sex allocation in a parasitoid wasp Nasonia vitripennis
AbstractInsect reproduction is influenced by various external factors including temperature, a well ‐studied constraint. We investigated to what extent different levels of sperm limitation of males exposed to different heat stresses (34 and 36 °C) affect females’ offspring production and sex allocation inNasonia vitripennis. In this haplodiploid parasitoid wasp attacking different species of pest flies, we investigated the effect of the quantity of sperm females received and stored in their spermatheca on their sperm use decisions, hence sex allocation, over successive ovipositions. In particular, we compared t...

Insecticide toxicity associated with detoxification enzymes and genes related to transcription of cuticular melanization among color morphs of Asian citrus psyllid
AbstractThe Asian citrus psyllid (Diaphorina citri Kuwayama) is known to exhibit abdominal color polymorphisms. In the current study, susceptibility to four insecticides was compared among orange/yellow, blue/green and gray/brown color morphs of field collectedD. citri. The LD50 values and 95% fiducial limits were quantified for each insecticide and color morph combination and ranged between 0.10 ng/ μL (0.06–0.10) and 6.16 ng/μL (3.30–12.50). Second, we measured the detoxification enzyme activity levels of orange/yellow, blue/green and gray/brown color morphs for cytochrome P450, glutathioneS‐transfera...

An unsettling explanation for the failure of skatole ‐baited ovitraps to capture Culex mosquitoes
AbstractCulex mosquitoes are primarily found in temperate and tropical regions worldwide where they play a crucial role as main vectors of filarial worms and arboviruses. In Recife, a northeast city in Brazil, high densities ofCulex quinquefasciatus are often found in association with human populated areas. In marked contrast to another part of the city, field tests conducted in the neighborhood of S ítio dos Pintos showed that trapping of mosquitoes in skatole‐baited ovitraps did not differ significantly from captures in control (water) traps. Thus, classical and molecular taxonomic approaches were used to analyz...

When parasitoids deal with the spatial distribution of their hosts: consequences for both partners
AbstractInsect parasitoids developing inside hosts face a true challenge: hosts are scattered in the field and their localization and selection require the use of complex and sometime confusing information. It was assumed for a long time that small ‐brained organisms like parasitoids have evolved simple and efficient behavioral mechanisms, leading them to be adapted to a given ecological situation, for example, the spatial distribution of hosts in the habitat. However, hosts are not static and their distribution may also vary through generat ions and within the life of parasitoid individuals. We investigated if and how p...

From laboratory to the field: consistent effects of experience on host location by the fruit fly parasitoid Diachasmimorpha kraussii (Hymenoptera: Braconidae)
AbstractAssociative learning is well documented in Hymenopteran parasitoids, where it is thought to be an adaptive mechanism for increasing successful host location in complex environments. Based on this learning capacity, it has been suggested that providing prerelease training to parasitoids reared for inundative release may lead to a subsequent increase in their efficacy as biological control agents. Using the fruit fly parasitoidDiachasmimorpha krausii we tested this hypothesis in a series of associative learning experiments which involved the parasitoid, two host fruits (tomatoes and nectarine), and one host fly (Bact...

Effects of seed mixture sowing with transgenic Bt rice and its parental line on the population dynamics of target stemborers and leafrollers, and non ‐target planthoppers
In this study, we examined the potential effects of intra‐specific seed mixture sowing with transgenicBt rice (Bt) and its parental non ‐transgenic line (Nt) (100%Bt rice [Bt100], 5% Nt+95%Bt [Nt05Bt95], 10% Nt+90%Bt [Nt10Bt90], 20% Nt+80%Bt [Nt20Bt80], 40% Nt+60%Bt [Nt40Bt60] and 100% Nt rice [Nt100]) on target and non ‐target pests in a 2‐year field trial in southern China. The occurrence of target pests,Sesamia inferens,Chilo suppressalis andCnaphalocrocis medinalis, decreased with the increased ratio ofBt rice, and the mixture ratios with more than 90%Bt rice (Bt100 and Nt05Bt95) significantly increased the pes...

Direct and indirect effects of light pollution on the performance of an herbivorous insect
AbstractLight pollution is a global disturbance with resounding impacts on a wide variety of organisms, but our understanding of these impacts is restricted to relatively few higher vertebrate species. We tested the direct effects of light pollution on herbivore performance as well as indirect effects mediated by host plant quality. We found that artificial light from streetlights alters plant toughness. Additionally, we found evidence of both direct and indirect effects of light pollution on the performance of an herbivorous insect, which indicates that streetlights can have cascading impacts on multiple trophic levels. O...

Glycosylation on proteins of the intestine and perimicrovillar membrane of Triatoma (Meccus) pallidipennis, under different feeding conditions
AbstractTrypanosoma cruzi, the causative agent of Chagas disease, interacts with molecules in the midgut of its insect vector to multiply and reach the infective stage. Many studies suggest that the parasite binds to midgut ‐specific glycans. We identified several glycoproteins expressed in the intestine and perimicrovillar membrane (PMM) ofTriatoma (Meccus)pallidipennis under different feeding conditions. In order to assess changes in protein ‐linked glycans, we performed lectin and immunoblot analyses on glycoprotein extracts from these intestinal tissues using well‐characterized lectins, and an antibody, which col...
