Effect of environmental temperature on development, fecundity, survival and predation of the snail-predatorSarcophaga misera (Dipt., Sarcophagidae)

Effect of temperature (10°–45°C) on development, fecundity, survival, population parameters, and rate of predation on snail by the flySarcophaga (Parasarcophaga) misera has been studied under controlled laboratory conditions. Temperatures ranging from 25°–30°C effected higher rate of development, fecundity, and predation on the snailIndoplanorbis exustus, than at 15°, 20°, 35° & 40°C. Longevity was maximum at 20°C. Implications of the role of temperature in influencing the biology and predation by this fly are discussed.
