Abstract:
Pink bollworm, Pectinophora gossypiella (Saunders), mating began 6 to 7 h after the last light in controlled-temperature cabinets. Moth pairs remained in copula 56 to 77 min. The average number of spermatophores transferred to females ranged from 0.9 for pairs confined for 1 night to 3.3 for pairs confined for 6 nights, and 84 to 100% of the pairs mated. Native moth pairs mated less frequently than laboratory-reared moth pairs. Laboratory-reared and native males mated an average of 8.9 and 0.9 times, respectively, during their life span when confined with virgin females each night. Male moths mated only once each night, whereas females (8%) mated twice each night when confined with two males. Female pink bollworm moths were less receptive to mating a second time on the night after the first mating.
