Abstract

Under laboratory condition the developmental periods of Cryptolaemus montrouzieri was reduced to an extent of 22.7 days at 35°C when fed with Planococcus citri while it was maximum (39.0 days) at 20°C. The adult longevity ranged from 47.4 to 51.2 days at 25°C and was less (37.6 days) at 35°C for both the sexes. The number of eggs laid per female (328.5) and feeding potential (182.6 nos) were maximum at 30°C than at 20°C and 35°C.
