The competitiveness of boll weevils, Anthonomus grandis Boheman, sterilized by three methods was measured in isolated 0.2 ha plots of cotton in 1981. Weevils sterilized by feeding on a diet containing 0.1% of an ecdysteroid, 3,514α-trihydroxy-5-cholest-7-en-6-one, followed by either irradiation (10 krad in N2) or fumigation (100 min at 30°C in bisazir) were significantly more competitive than those sterilized by feeding on a diet containing 100 ppm diflubenzuron and irradiated (10 krad in N2). Laboratory quality control tests conducted in conjunction with the field tests indicated that the ecdysteroid-fed, irradiated males had a higher mating capability, lived longer, and were just as sterile as the difluhenzuron-fed irradiated males. All three treatments caused complete or near complete sterility in females.
