Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

Insect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope

Integrative Zoology, EarlyView.
The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

Integrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

Integrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

The amino terminal domain of the human α7 nicotinic acetylcholine receptor subunit leads to the functional expression of human/insect receptors

British Journal of Pharmacology, EarlyView.
Human α7 receptors have been characterised in terms of pharmacological properties. Insertion of the N‐terminal domain of the human α7 subunit leads to honeybee and cockroach chimeric receptors activated by ACh and inhibited by α‐Bgt. Insertion of the human cys‐loop leads to cockroach chimeric receptors modulated by PNU.
