Oviposition and development of the mealybug parasitoid Anagyrus pseudococci (Girault) at different constant temperatures.
Oviposition and rate of development of Anagyrus pseudococci, a parasitoid of Planococcus citri, were determined at constant temperatures of 18, 21, 24, 27, 30 and 33°C in the laboratory. Most progeny were produced at 27 and 30°C. The developmental rate for both the sexes showed a good fit to a linear regression model over a wide range of temperatures. Males developed faster than females at all temperatures. The lower developmental threshold was estimated to be 13.06 and 12.57°C for males and females, resp. The estimated thermal requirement for development was 195.50 degree-days for males and 219.59 degree-days for females.
