Abstract
Three species of Trichogramma; T.pretiosum, T.minutum and T.evanescens have been tested in order to study their development on factitious host eggs of two important pests in Egypt (black cutworm and potato tuberworm) as an initial step for the use in IPM programs. Several biological parameters were evaluated such as, parasitism %, emergence rate, development duration, longevity, sex ratio and number of embryos/egg. T.evanescens was very promising as a biocontrol agent for both pests.
