A population of Clitostethus arcuatus (Rossi), originating in Israel, was imported into California in 1989. Laboratory studies at three temperatures (21.1, 28.2, 32.2 degrees C) using Siphoninus phillyreae (Haliday) as prey indicated maximum developmental rates, survival, and fertility at 28.2 degrees C. At 28.2 degrees C, development from egg to adult required a mean of 15.6 d, egg-to-adult survival was 78%, sex ratio of surviving progeny was 1:1, females lived an average of 82 d and laid an average of 202 eggs. Developmental rates and fertility were slightly lower and survival was similar at 21.1 degrees C. Development was slower and survival and fertility were reduced substantially at 32.2 degrees C.
