Studies of two parasites of olive scale,<i>Parlatoria oleae</i>(Colvée): II. The biology of<i>Coccophagoides utilis</i>Doutt (Hymenoptera: Aphelinidae)

Abstract

Coccophagoides utilis is arrhenotokous. The females develop as internal primary parasites of Parlatoria oleae whereas the males develop adelphoparasitically on the prepupal and pupal stages of their own species. A significant aspect of the life history of C. utilis is a mechanism of retarded development in certain female progeny which ensures that the males on emerging meet with females.
