Is there hybridization between 2 species of the same genus in sympatry? —The genetic relationships between Anoplophora glabripennis, Anoplophora chinensis, and putative hybrids
A summary of morphological identification, population genetic analyses, and attempted hybridization, we demonstrate that the putative hybrid is morphologically different from the previous descriptions published for ALB and CLB populations. The genetic analysis strongly supports the phylogenetic conclusion that the putative hybrid is a morphological variant of ALB. AbstractAnoplophora glabripennis (Asian longhorn beetle, ALB) andAnoplophora chinensis (Citrus longhorn beetle, CLB) are native forest pests in China; they have become important international quarantine pests. They are found using the sameSalix aureo-pendula host...

Identification of an odorant receptor responding to sex pheromones in Spodoptera frugiperda extends the novel type ‐I PR lineage in moths
In this study, we investigated whether ORs of the pest mothSpodoptera frugiperda belonging to clades closely related to this novel PR lineage may also have the capacity to bind type-I pheromones and serve as male PRs. Among the 7 ORs tested, only 1 (SfruOR23) exhibited a male-biased expression pattern. Importantly,in vitro functional characterization showed that SfruOR23 could bind several type-I sex pheromone compounds withZ-9-tetradecenal (Z9-14:Ald), a minor component found in female sex pheromone glands, as the optimal ligand. In addition, SfruOR23 also showed weak responses to plant volatile organic compounds. Altog...

Larval development and voracity of Eupeodes americanus (Diptera: Syrphidae): comparison of the focal prey Aphis gossypii (Hemiptera: Aphididae) and the banker prey Rhopalosiphum padi (Hemiptera: Aphididae)
The American hoverflyEupeodes americanus (Wiedemann) could be a good a biocontrol agent to control the melon aphid (Aphis gossypii Glover), which induces a lot of damage in cucumber crops. Preimaginal development time, survival rate, and occurrence of deformation are similar on both the focal prey,A. gossypii, and the banker prey, the bird cherry-oat aphid (Rhopalosiphum padi L.). Third instar and pupal weight are higher for larvae fed with the banker prey. Thead libitum voracity of the syrphid larvae was very high and similar on both preys except for the third-instar larvae which consumed more focal prey. AbstractUnlike E...

Survival effects of antibiotic exposure during the larval and adult stages in the West Nile virus vector Culex pipiens
We analyzed adult survival effects of antibiotic exposure during mosquito development through a paired two-way factorial experimental design. Larval exposure to antibiotics significantly increased the survival rate of nontreated adult females. In addition, for both male and female mosquitoes, shorter larvalad libitum feeding periods rapidly reduced the survival rate of antibiotic-treated mosquitoes compared to those emerged later, while these differences disappeared in control adult mosquitoes. AbstractThe ability of mosquitoes to transmit a pathogen is affected, among other factors, by their survival rate, which is partly...

Gustatory responsiveness in Vespula germanica workers: exploring the interplay between sensory perception and task specialization
This study investigates the responsiveness to carbohydrates or proteins inVespula germanica workers and the interplay with task specialization. The research aims to describe the behavior of wasps and explore the underlying mechanisms behind the labor division strategy adopted by workers. The study establishes a protocol for measuring gustatory sensitivity in harnessed wasps and examines the perception and discrimination of sucrose and amino acids. The results reveal differences in responsiveness thresholds between preforaging and foraging workers, providing insights into the task specialization ofV. germanica. However, fur...

Cover Caption
Researchers and producers are exploring ways to repurpose organic waste. Larvae of the black soldier fly (BSF),Hermetia illucens, offer a solution for converting organic waste into high-quality protein and organic fertilizers. These saprophagous insects can fully utilize abandoned organic resources, promoting waste reduction. In order to make the BSF more efficiently use organic waste, scientific and technological workers have carried out a series of studies to solve various basic and transformational problems that BSF may face in its application (see pages 888-1021). Due to limited space, this issue only covers part of th...

Mitogenome ‐based phylogeny of mosquitoes (Diptera: Culicidae)
In this study, we reconstructed the phylogenetic relationships of 149 Culicidae species using mitochondrial genomes and estimated their divergence times. Our findings provide a basis for further research into the evolutionary biology of Culicidae. AbstractMosquitoes are of great medical significance as vectors of many deadly diseases. Mitogenomes have been widely used in phylogenetic studies, but mitogenome knowledge within the family Culicidae is limited, and Culicidae phylogeny is far from resolved. In this study, we surveyed the mitogenomes of 149 Culicidae species, including 7 newly sequenced species. Comparative analy...

Alternative relay regulates the adenosine triphosphatase activity of Locusta migratoria striated muscle myosin
The motor domain of locust striated muscle myosin heavy chain (MHC) contains 4 regions (N-SH3, ATP-lip, relay, and converter), which are encoded by alternative-splicing exons. FL1 and AB4, the 2 isoforms of MHC, have different motor activities, which are majorly regulated by the alternative relay encoded by exon-14a/c. AbstractLocust (Locusta migratoria) has a single striated muscle myosin heavy chain (Mhc) gene, which contains 5 clusters of alternative exclusive exons and 1 differently included penultimate exon. The alternative exons ofMhc gene encode 4 distinct regions in the myosin motor domain, that is, the N-terminal ...

Intraspecific scaling and early life history determine the cost of free ‐flight in a large beetle (Batocera rufomaculata)
Methodological restrictions limit our understanding of the scaling of flight energetics with body mass in free-flying insects particularly at the intraspecific level where variation in body mass is low. The tree-boring beetle,Batocera rufomaculata (i), exhibits a large intraspecific variation in adult size resulting from the condition of the host tree during larval growth (ii). We applied the13C stable isotope method to investigate the scaling of energetics with body mass during free-flight in an open environment of adults ranging in body mass from 1 to 7 g (iii). We show that flight metabolic rate scales with body mass to...

Both host and diet shape bacterial communities of predatory mites
Our research revealed that both host species and dietary variation modify the microbial composition of predatory mites. Although predatory mites had stable core microbiota, microbiome fluctuation indicated that predatory mites had weak dependence on their microbial communities which were greatly influenced by diet. The association is closely related to predatory mite species. AbstractMicrobial communities, derived from food, ambient, and inner, can affect host ecological adaption and evolution. Comparing with most phytophagous arthropods, predators may have more opportunities to develop specific microbiota depending on the...

Effect of short neuropeptide F signaling on larval feeding in Mythimna separata
RNA interference ofsNPF and its receptors inhibited food intake of larvae and further affected feeding-related developmental growth, which provided a potential target for pest control ofMythimna separata. AbstractMythimna separata is a notorious phytophagous pest which poses serious threats to cereal crops owing to the gluttony of the larvae. Because short neuropeptide F (sNPF) and its receptor sNPFR are involved in a diversity of physiological functions, especially in functions related to feeding in insects, it is a molecular target for pest control. Herein, ansNPF and 2sNPFRs were identified and cloned fromM. separata. B...
