Abstract

Cybocephalus nigriceps nigriceps (J. Sahlberg),C. micansReitter,C. aegyptiacusEndrody-Younga, andC. binotatusGrouvelle were able to develop and reproduce while feeding on the California red scale,Aonidiella aurantii (Maskell), or on the Florida red scale,Chrysomphalus aonidum (L.). The ivy scale,Aspidiotus hederae (Vallot), was not suitable as a diet for the reproduction, developmen and survival of any of the 4Cybocephalus species. However, the suitability to the prey as a diet varied among the 4 species, being greatest withC. n. nigriceps and least withC. micans.

Pollen ofCarpobrotus, eggs of some moths, and non-armoured scales, as well as various stages of a whitefly, an aphid, and a red spider mite, did not enable development or reproduction ofC. micans.

Résumé

Cybocephalus nigriceps nigriceps (J. Sahlberg),C. micansReitter,C. aegyptiacusEndrody-Younga etC. binotatusGrouvelle, peuvent se développer et se reproduire en s'alimentant soit de la cochenilleAonidiella aurantii (Maskell), soit duChrysomphalus aonidum (L.). La cochenilleAspidiotus hederae (Vallot) n'a pas permis la reproduction, le développement et la survie de 4 espèces deCybocephalus. Cependant une variabilité entre ces 4 espèces concernant la valeur nutritive de cet hôte a été constatée. Elle était la plus haute pourC. n. nigriceps et la plus basse pourC. micans.

Le pollen deCarpobrotus, les œufs de quelques Lépidoptères et de cochenilles sans armure, ainsi que les différents stades d'un aleurode, d'un puceron et d'une araignée rouge n'ont pas abouti au développement et à la reproduction deC. micans.
