Insect Science, EarlyView.In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.

Insect Science, EarlyView.Overview of the mindset and long‐term goals with the approach suggested in this study. We provide a first proof of concept that male‐killing endosymbionts can be used to establish female biased populations with higher production efficiency than populations with a 50/50 sex ratio. This biological tool can have marked positive impact on future commercial

Insect Science, EarlyView.Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Insect Science, EarlyView.The Australian giant wood moth (Endoxyla cinereus) feeds within the galls of scale insects (Apiomorpha) before transitioning into its wood‐boring eucalypt larval phase. This transitionary phase may be key to its multi‐year development, at the end of which it can produce over 100 000 eggs.

Aphid and endosymbiont sensitivity to heatwaves is misaligned across life stages
Insect Science, EarlyView.Aphids depend on the obligate symbiont Buchnera aphidicola, which may constrain thermal tolerance. Using a factorial heatwave experiment, we exposed nymphs and adults to moderate or extreme temperatures and measured fitness and symbiont responses.

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.

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females
Integrative Zoology, EarlyView.We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

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 ...
