Effect of temperature on life cycle and behaviour of Aedes aegypti (Diptera: Culicidae)

In this study, effect of increasing temperature on life cycle, mortality, and behavior the mosquito species, Aedes aegypti was evaluated. Heat shock applied at 32°C, 37°C 42°C for 20 minutes, 1 hour 2 hours each to egg, 2nd instar, 3rd instar pupal stage separately changes in cycle pattern recorded a routine basis. The control 27°C which reared. When heat-shock eggs, developmental period found be inversely proportional rise. shortest embryonic larval stages were (2h). full development also No hatching 42°C. While heat larvae, larvae pupae, similar decreased observed. 100% viability observed upon (2nd instar) pupae 32°C. case 37°C, decreased. egg hatched 42°C, while few instars survived. Lowest rate counted Change movement gradually with temperatures pupae. change irregular larvae. highest 32°C 27°C, respectively lowest Bangladesh J. Zool. 49 (3): 369-379, 2021
