Abstract
The optimum temperature range for development and survival of the predacious coccinellid Coleomegilla maculata and its parasite Perilitus coccinellae is 24° to 26.7°. Theoretical thresholds for development (t) of the pre-imaginal stages of C. maculata range from 9° to 13°. Total development (from oviposition to adult emergence) of the beetle requires an accumulation of 236 heat degree days (K) above 11.3° (i), whereas the development of P. coccinellae requires 395 heat degree days (K) above 9.8° (t). To predict the seasonal interaction between C. maculata and P. coccinellae, and to manage C. maculata efficiently as a biological control agent, it is vital to know the thermal and dietary requirements of the two species.
