Abstract
Following the successful biological control of Florida red scale, Chrysomphalus aonidum (L.), in the main citrus-growing areas of Israel by an introduced parasite, Aphytis hotoxanthus DeBach, intensive efforts have been made in Israel during the past decade to improve the biological control of citrus pests and to develop an in tegrated control program. The review of these efforts includes the identification and appraisal of locally established natural enemies of citrus pests, introduction and liberation of exotic parasites and predators, and evaluation of pesticide selectivity.
