Rhythmic biosynthesis of sex pheromone modulates the calling and mating behaviors of Tuta absoluta (Lepidoptera: Gelechiidae)

New Plant Protection, Volume 2, Issue 4, December 2025.
The six‐step “morning flight–mating” behavioral sequence in Tuta absoluta is characterized by rhythmic behavior occurring from 05:30 to 08:00, with a peak from 05:30 to 06:30. This “morning flight–mating” rhythm in T. absoluta is regulated by the rhythmic release of sex pheromones.

Time Constraints Modulate the Effects of Predator Cues and a Metal Across Life Stages in a Damselfly

Evolutionary Applications, Volume 18, Issue 11, November 2025.
ABSTRACT Animals are increasingly exposed to multiple co‐occurring stressors. Environmental factors such as seasonal time constraints (TC), predation risk, and pollutants strongly influence fitness‐related traits in aquatic organisms. Yet, the interactive effects of such stressors, especially across life stages, remain unclear.
