In: Mansoura University Journal of Agricultural Sciences 2008.v.33(9)Summary: The efficiency of some insect parasitoids associated with the pink [Peclinophora gossypiella (Saund.) (PSW)] and spiny [Earias insulana (Soisd.) (SSW)] bollworms was evaluated under field conditions in Dakathlia Governorate. Bilqas district. throughout two successive cotton seasons (2006 and 2007). The present results revealed that, three hymenopterous parasitoids were recorded on PBW larvae, these parasitoids namely, Parasierola sp.. Habrobarcon sp. and Exeristes roberator (F.). While. on SSW larvae, only one parasitoid species (Habrobracon sp.) was recorded. The parasitoids showed low role of activity on both PSW and SSW larval populations.
