Abstract

The name Trichogramma pretiosum Riley is removed from synonomy with T. minutum Riley on bases of morphological and behavioral differences between the species. The early differentiation of these 2 species merely on the basis of host relations is confirmed. T. euproctidis Girault also is removed from synonymy.
