Abstract:
Abstract. 1. The Mediterranean black scale Saissetia oleae (Olivier) was the most suitable host for the imported Metaphycus aff. stanleyi Compere and Metaphycus helvolus (Compere) and for the local Metaphycus flavus (Howard). 2. Difficulties were encountered in the mass rearing of the introduced parasitoids, particularly M. aff. stanleyi, on the hemispherical scale Saissetia coffeae (Walker) and on the brown soft scale Coccus hesperidum L., because many of the eggs were encapsulated. 3. Although all the eggs of M.aff.stanleyi were encapsulated shortly after being deposited in S.coffeae, some larvae developed, broke out of the capsule and developed normally. 4. The incidence of parasitized scales containing only encapsulated eggs of any of the three Metaphycus species, increased with the stage of the host. Copyright © 1977, Wiley Blackwell.
