Title

Effect of gamma radiation on the black cutworm Agrotis ipsilon (Hufn.): irradiation of eggs and larvae.

Year

1985

Source

African J. Agric. Sci., 12(1-2):155-162).

Abstract

The mortality of eggs of the noctuid A. ipsilon exposed in the laboratory to gamma radiation was directly related to the increase in dose or the decrease in age of the eggs. When 3rd instar larvae were exposed at 20 - 300 Gy, all those treated at 150 Gy died during the larval stage, whereas at 80 Gy about 30% of the larvae pupated and 40% of the pupae gave rise to malformed adults. When fully-grown larvae were exposed to 200 Gy, they died during the larval stage, but 80 Gy permitted 40% of the larvae to pupate, although none of the pupae gave rise to adults. Mortality increased with dosage, and irradiation resulted in delayed development and an adult sex ratio that favored males.
