Abstract:
Low (0°-4°C) and high (40°-48°C) temperatures to which two scales insects:Saissetia coffeae (Walker) and Coccus hesperidum L. (Homoptera: Coccidae) were subjected, before exposure to the encyrtid Metaphycus aff. stanleyi (Compere), reduced egg encapsulation of the parasitoid in the two hosts. Consequently the mass rearing of M. aff. stanleyi was greatly improved. © 1976 Birkhäuser Verlag.
