Abstract

Studies on the biology of Phygadeuon trichops Thoms. (Hym., Ichneumonidae.) Studies on the biology ofPhygadeuon trichops Thoms. (Hym., Ichneumonidae). Biological data, which were pointed out with one or several couples of ichneumonids per testcage, are reported such as life-span, reproductive capacity, duration of larval development, sex ratio, rhythm of oviposition, duration of copulation, supra parasitying, number of exit holes in the host pupa and the ratio of the F1-progeny and real produced eggs. As host pupae for the ichneumonids pupae of the onion fly were used, which can be breeded easily in large scale.
