Starvation-Induced Disruption of Nocturnal activity in the tropical house cricket, Gryllodes sigillatus

Feeding state potently modulates foraging behavior and locomotor activity. Here, we examined activity patterns across developmental stages in the nocturnal tropical house cricket or banded cricket, <i>Gryllodes sigillatus</i> . Adult males and females exhibited robust nocturnal behavior, with nocturnality emerging earlier in females during development. Starvation significantly reduced overall activity and abolished nocturnal activity patterns in females, but not in males. These results reveal sex-dependent differences in the developmental and feeding-state regulation of nocturnal behavior in <i>G. sigillatus</i> and lay the groundwork for future studies on how nutrient stress modulates behavior in this species.
