Sterility and mating competitiveness of male ceratitis capitata as affected by gamma radiation and di methane insecticide. Vol. 4

Abstract

In the present work, the effects of pupal gamma-irradiation (50, 70, 90 Gy), or adult treatment with dimethoate insecticide (0.93 ppm) on the male sterility and mating competitiveness of the medfly, ceratitis capitata (Wied.) were studied. Results indicated that treatment of the adult medfly with dimethoate had no clear effect on male fertility whether this male mated with treated or normal females. However, gamma irradiation drastically decreased hatch ability of eggs laid by normal or treated (dimethoate) females, when mated with irradiated males all gamma doses. This reduction in egg hatch ability increased increased with increasing gamma dose. Irradiated females did not lay eggs at any of the gamma doses used. At all mating combinations, the male mating competitiveness was decreased especially when irradiated males were confined with treated males for mating with normal or treated females. Results are indicated and discussed in the text. 4 figs.
