There is a high cost of not responding to the threat of predation; therefore, organisms have evolved different risk avoidance strategies. Animals use different cues (e.g., alarm calls, kairomones, refuge density) in their surroundings to save themselves from predators. They may also use past encounter experiences to improve their antipredator responses. Such carry-over effects can benefit the same individual or subsequent generations where animals occupy the same ecological niche. In a complex life cycle, every life stage differs morphologically, physiologically and functionally. These stages occupy different ecological niches and experience different selection landscapes. In such life cycles, every life stage is separated by a tissue remodelling event. Given these evolutionary and physiological constraints, do past predator encounters carry over to the next stage and influence its behavioural response? Or do they respond according to their immediate environment?   In the first chapter of my thesis, we answered these questions using a mosquito model system Aedes aegypti. Aedes aegypti has four major stages- egg, larva, pupa, and adult. We examined the effect of predation risk experience across larval and pupal stages. Larval and pupal stages differ in morphology, physiology and function but share the same habitat and, therefore, similar threats. We manipulated the threat of predation experienced by larvae and investigated its influence on pupal behaviour. I will present my findings during the talk and an overview of my PhD work progress.
