Hyperparasites (Xyphigaster pseudococci, Homalotylus flaminius, Prochiloneurus pulchellus) have been found attacking Anagyrus, Exochomus and Coccodiplosis species.

Abstract

Summary The occurence of several predators, parasites and hyper-parasites is reported and their relationship is studied in detail. A new species of the genus Anagyrus is recorded. Several Coccinellids (Exochomus flaviventris, E. concavus, Hyperaspis senegalensis hottentotta), Cecidomyiids (Coccodiplosis citri, Dicrodiplosis sp.), Lycaenid (Spalgis lemolea) and Anthocorid (Cardiasthetus exiguus) are involved in the natural regulation of the pest population. Hyperparasites (Xyphigaster pseudococci, Homalotylus flaminius, Prochiloneurus pulchellus) have been found attacking Anagyrus, Exochomus and Coccodiplosis species. An additional Encyrtid (Cheiloneurus cyanonotus) develops upon the hyperparasite Homalotylus. Data are given on the dynamics of the entomophagous insect populations, the time of their intervention, the rate of parasitism and predatism.
