Tobacco budworm: behavioral studies of the sterile hybrid backcross in field releases in Puerto Rico
Environmental Entomology 13 (3), 701-707
Abstract: When tobacco budworm (TBW), Heliothis virescens (F.), males are mated with H. subflexa (Guenée) females, the male progeny are sterile and the female progeny are fertile. Backcrossing the hybrid females to TBW males also results in sterile male and fertile female progeny, a condition that persists through successive generations. Results from field releases of laboratory-reared backcross insects into the native TBW population in Puerto Rico indicate that the backcross insects mate with the wild insects and that there is good potential for the infusion of the sterility factor into the native population.
