Experimentally induced interspecific matings between Heliothis virescens male and H. subflexa female moths result in sterile male and fertile female offspring. The fertile female progeny can be backcrossed with H. virescens males to produce more ster

Testes of adult Heliothis virescens, H. subflexa, and backcross males derived from crosses between H. virescens males and H. subflexa females were examined for the presence of virus-like particles (VLPs). These spherical 45- to 50-nm VLPs were first

When 2- to 3-day-old male Musca domestica L. (Diptera: Muscidae) were injected with 20 µg of 1,3 propanediol dimethanesulfonate, most sperm had dominant lethal mutations so the males were sterile in the initial matings. Testes sectioned at regular i
