Abstract:

Male pupae of Heliothis virescens (F.) reared on diets containing 0.1% (wt/vol) reserpine and then exposed to 15 or 20 krad of gamma irradiation, all substerile doses for the strain, gave rise to P1 males that transmitted delayed sterility to their F1 and F2 progeny. This delayed sterility had its greatest expression in the F1 ♀ progeny. Irradiation of the ♂ pupae with 10, 15, 20 or 25 krad adversely affected the emergence of F1 females, and the greater the dose, the fewer females produced. Oviposition, egg fertility, and the number of F1 progeny produced per female were not dependent on mating frequency.
