Abstract
Trissolcus djadetshkoe (Hym.: Scelionidae) is an inferior egg parasitoid of sunn pest Eurygaster integriceps Puton
(Hem.: Scutelleridae) in Iran wheat fields. This is reason that why this species is less considered in biological control as well as
research programs. However a parasitoid with a minor effect is not necessarily an unimportant species. Although this species is an
eligible mortality factor in many parts of Iran, it is the second abundant species of northwest of Iran. Its efficacy was studied in terms
of life history parameters in laboratory (26±1 ºC, 50±10% RH, and 16: 8 h photoperiod). The sex ratio, net replacement rate and
intrinsic rate of increase were 0.57±.03, 39.8±2.9 and 0.212±0.004 respectively. Efficacy of this species was compared to other
egg parasitoids of the sunn pest.
