Abstract:For cytogenetic study, testes of the larvae of corn earworm, Heliothis zea (Boddie), and tobacco bud worm, H. virescens (F.), were collected on St. Croix, U.S. Virgin Islands, from natural populations that had been subjected to daily releases of irradiated moths. Of the corn earworm larvae examined, 26.9% had at least one chromosome translocation, a fact which indicated some success in introducing inherited sterility into the population. In contrast, only one tobacco budworm out of 442 examined had a possible chromosome abberration. Either the budworm population was unaffected by the releases, or there was no survival of progeny from the partially sterile moths released. The hatch of field-collected eggs showed virtually no suppression of the bud worm population that could be attributed to the releases. The study shows that a population can he sampled and examined cytogenetically to assess population suppression through genetic manipulation.
