Abstract:Laboratory studies were conducted with Musca autum- nalis De Geer to determine the number of times a female usually mates and the competitiveness between untreated males and chemosterilized males. Two methods were used to study female mating habits: In one, untreated virgin females were mated to treated virgin males (fed 0.005% or 0.01 % tepa) and then caged with untreated virgin males. If the female successfully mated again, an in crease in pupal production should have occurred. In the other method, untreated females were mated with treated males and then caged with untreated males as in the first method. However, any female which appeared willing to mate with an untreated male was immediately checked to see whether she had received any sperm from the treated male. This method was feasible, because in all the tests the average time a pair remained in copulation was about 65 min. Resu1ts indicated that most females mated only once, and that females attempting to mate again were those that had not received any sperm during the first mating. A study of competitiveness involved using different ratios of untreated males, sterilized males, and untreated females. Results indicated that an 8: 1 ratio of sterilized males to untreated males reduced pupal production 94% and that lower ratios were proportionally less effective.
