| Abstract: | "Sterilization by irradiation was studied in 0-24 hour old males of Cadra cautella (Ephestia cautella) exposed to 40 Krad of gamma radiation from a 60 cobalt source at a rate of 2250-2200 rad/minute in the presence of female sex pheromone. This radiation dose failed to induce the desired degree of sterility in the absence of pheromone. Pheromone was extraced from the virgin females and applied to filter paper at doses of .1, .5, and 1 female equivalent which was then introduced into containers containing 15-18 males 3 minutes prior to irradiation. Excitation and increased activity of the insects was observed when compared to the controls without the pheromone. The proportion of low percentage hatch increased with increased pheromone presence. The difference between absence and presence of pheromone was marked. It is concluded that these results are evidence of the value of this approach of preconditioning to irradiation when induction of sterility is the objective. eng" |
