Insect responses to drought events and salinity stress: unveiling direct and indirect effects

The future holds a projection of escalated occurrences of extreme climate events, which are expected to affect insect life substantially. Extensive research efforts in this field have witnessed rapid expansion despite significant gaps in knowledge. This review article addresses a deeper understanding of the impacts of severe climate events on insects that outline promising avenues for future research in this field. Drought has emerged as one of the predominant forms of extreme climate events that have extensively influenced insects, as frequently documented in the literature. The significance of drought occurrences on insects is crucial within the climate change scenario. Furthermore, the increasing occurrence and intensity of drought episodes, which are associated with changes in the climate, can result in elevated salinity levels in water bodies and soils. These changes have far-reaching implications for ecosystems, including impacts on biology, survival, and insect behavior. This review aims to analyze developments in information acquisition with anticipated climate change implications, particularly drought and salinity, on various aspects of insect life.
