Heat-shock mortality and induced thermotolerance in larvae of the mosquito Anopheles albimanus.

Temperature effects on Anopheles albimanus larval survival were investigated. Larvae were exposed to 30 min heat shocks at various temperatures. Almost no mortality was observed at 40 degrees C, but was complete at 43 degrees C. Increased larval thermotolerance could be induced by higher rearing temperature or by a 30 min exposure to 37 degrees C.
