Effect of gamma irradiation on fertility of potato tuber moth males and study of inherited sterility phenomena in partially sterile males

Abstract

Newly emerged adult males (0-18 h) potato tuber moth (PTM) phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) were irradiated with various doses of gamma irradiation ranging from 5 to 45 krad. Sterility in order of 91% was induced when males were irradiated with a dose of 45 Krad. Longevity of male PTM was not affected by the application of irradiation, while mating ability and frequency of mating of the males irradiated with 25, 35 and 45 Krad were decreased. The mean number of eggs laid by females mated with males irradiated at 35 and 45 Krad was lower than the control. When males PTM were irradiated with high doses their competitiveness values were reduced, while the competitiveness was increased when the sex ratio of irradiated males to normal males was increased, specially with ration 1 : 10 : 1 (Normal male: Irradiated males: Normal female). Application of 15 Krad dose permitted, the ability to obtain a desired level of male sterility with acceptable reduction in its competitiveness. The inherited sterility phenomena in partially sterile males irradiated with 10-15 and 20 Krad was studied. Sterility in F1 progeny was higher than that in their irradiated male parents. The sex ratio of F1 progeny  More>>
