Abstract

Several systematic and genetical problems are dealt with in Trichogramma embryophagum and T. cacoeciae. The difficulty in finding the description of T. embryophagum and the poor descriptions of both species have induced nomenclatural problems which are treated here. The particular reproductive system of these species led authors to hypothesize about the origin of T. cacoeciae and the sex determination of Trichogramma. Alternative hypotheses are proposed. New electrophoretic results in T. cacoeciae are reported and interpreted taking into account the mode of reproduction. Newgeographical data are also provided.
