Abstract:

Moths of the bollworm, Heliothis zea (Boddie); and the tobacco budworm. H. virescens (F.); collected from 1966 through 1969 in insect traps equipped with a black-light lamp were sexed, and samples were dissected to determine the degree of depletion of the fat body, the development or depletion of the ovaries, and the number of spermatophores per female. Captured bollworm moths averaged 49.7% female (range 32.6-68.4%); captured tobacco budworm moths averaged 28.3% female (range 17.3-60.0%), Of 2189 female bollworm moths dissected, 57.9% were unmated; of 123 female tobacco budworm moths dissected, 55.3% were unmated. Mated females of both species had mated 1 time most frequently, but some had mated as many as 6 times.
