Development, survival, reproduction, sex ratios and population growth statistics of Dactylopius ceylonicus on Opuntia vulgaris at constant temperatures of 18, 22, 26, 30 and 34 ° C are reported. Populations of D. ceylonicus can increase at constant temperatures above 16.7 ° C and the rate of increase reaches a peak near 30 ° C. The most favourable temperatures for D. ceylonicus development, survival and reproduction were 26 and 30 ° C. The relevance of this to control of O. vulgaris and breeding of D. ceylonicus for field release are discussed.
