The aim is to study the effect of gamma radiation producing from (Cs-137) at doses of (1-5 Gy) on the morphology and histology of female reproductive system of cowpea beetle, Callosobruchus maculatus (F.) and their malformations.

The obtained data are summarized as follows: The normal female reproductive system was containing two ovaries each consist six ovarioles, bursa copulatrix, two Calyx, two lateral oviducts, spermatheca, spermathecal gland and vagina.

The irradiated females ovaries from 1-day old eggs were consists of bursa appear, bursa enlarged, ovarioles reduced, no calyx (empty) with 1, 2, 3 and 5 Gy.

Moreover, the irradiated female ovaries form 3-days old eggs were consists of bursa appear, ovarioles reduced and calyx without mature eggs with 1, 2, 3, 5 and 10 Gy.
