Actin dynamics controlled by IqgC, a RasGAP at the crossroads between the IQGAP and fungal GAP1 families

FEBS Open Bio, Volume 16, Issue 2, Page 268-278, February 2026.
IqgC is a RasGAP from Dictyostelium discoideum. IqgC binds RasG via its RasGAP domain and deactivates it on macroendocytic cups, thereby suppressing the uptake of fluid and particles. IqgC has a positive effect on cell‐substratum adhesion, and its RGCt domain is required for recruitment to ventral foci.

Pheromone binding proteins enhance the sensitivity of olfactory receptors to sex pheromones in Chilo suppressalis

Scientific Reports, 2015
Sexual communication in moths offers a simplified scenario to model and investigate insect sensory perception. Both PBPs (pheromone-binding proteins) and PRs (pheromone receptors) are involved in the detection of sex pheromones, but the interplay between

The Effect of Differing Levels of Intrasexual and Intersexual Selection on Survival and Reproduction Under a Heatwave

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Precopulatory mating behaviour, are important for fitness and can be disrupted by heatwave's. Here we assess how differing levels of intrasexual and intrasexual selection in precopulatory mating behaviours impacts fitness responses to heatwaves. We find that the likelihood of having a brood is impacted by differences in intrasexual and intersexual ...

Sex matters: European urban birds flee approaching women sooner than approaching men

People and Nature, Volume 8, Issue 2, Page 316-326, February 2026.
Abstract Flight initiation distance (FID) is a metric often used to study an individual's perceptions of risk when facing a predatory threat. Longer FID indicates lower risk‐taking, while shorter FID identifies bolder individuals who tolerate greater risk.

Bed bug preferences for host odor or aggregation odor are differentially modulated by physiological state in various odorscapes

Pest Management Science, Volume 82, Issue 2, Page 1426-1436, February 2026.
The bed bug olfactory system is highly tuned to two odor sources with dedicated odor information‐processing pathways that are modulated by the satiety–hunger state. Understanding the dynamic nature of switching odor preferences at different phases of blood digestion will contribute to the development of lures with host kairomones and aggregation ...

Initial studies of mating disruption of the tomato moth, Tuta absoluta (Lepidoptera: Gelechiidae) using synthetic sex pheromone

Journal of the Brazilian Chemical Society, 2000
The potential of the synthetic major component of T. absoluta (Meyrick) sex pheromone for mating disruption was studied in small plots (0.01 hectares) with fresh-market tomato crop.

Attack density negatively affects reproductive success but not fecundity or offspring body size in a bark beetle

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 76-81, February 2026.
Neither gallery length nor eggs per female varied significantly with attack density, suggesting P. proximus adults disregard galleries constructed by conspecifics and continue to lay eggs irrespective of attack density. Number of adult offspring per female decreased significantly as attack density increased, indicating that intraspecific competition ...

From beginning to end: the synecology of tree‐killing bark beetles, fungi, and trees

Biological Reviews, Volume 101, Issue 1, Page 314-335, February 2026.
ABSTRACT Over a century of research has revealed an amazing complexity of behaviours and physiological adaptations that allow tiny bark beetles to overcome large trees, sometimes resulting in outbreaks that kill millions of trees. Turning a tree into a home and successfully raising offspring involves constant interactions among the beetles, the tree ...

Reproductive Status of Boll Weevils During Season and Off‐Season of Cotton in the Cerrado of Brazil

Entomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 113-122, February 2026.
Cotton boll weevils were monitored continuously and counted weekly over two agricultural years in the Brazilian Cerrado. The survey resulted in a total of 94 519 adults captured in approximately similar percentages of females and males during both the growing and off‐seasons.
