Abstract:

The effects of 60Co γ-ray irradiation on male sterility of indoor-reared Apriona germari were studied. The results showed that the male adults of A. germari irradiated with 60Co γ-ray of 100, 150, 200, and 250 Gy maintained the normal levels of feeding, excretion and mating. The male adults successfully mated the female adults without irradiation, and the mated females were able to cut grooves and oviposit normally. Additionally, the longevity of the irradiated male adults were not affected except for that with the highest dosage of 250 Gy that decreased obviously the insect longevity. The mated female adults with the mail adults irradiated with 60Co γ-ray of 150, 200, 250 Gy had the normal eggs, but the eggs failed to hatch. Thus, the dosages of 150, 200, 250 Gy were considered to be sterile irradiation of A. germari. In addition, the 100 Gy irradiated males also largely reduced the larvas hatching rate to only 0.76%, showing that this dosage could be considered sub-sterile irradiation of A. germari. In terms of the cost and effect, the dosage of 150 Gy was recommended for practical usage.

Key words: Apriona germari, 60Coγ-ray, irradiation, effect, male sterility
