| Popis: | The effect of a benzyl-1,3-benzodioxole derivative (BBD), J3230 (5-propyl-1-en-3-oxy-6[1-(4-methyoxyphenyl)ethyl]-1,3-benzodioxole) on reproduction of the oriental fruit fly, Bactrocera dorsalis (Hendel), was investigated by exposing late 3rd instars to topsoil treated with this chemosterilant. Adult emergence and subsequent egg hatch were significantly reduced. J3230 affected primarily the reproduction of male oriental fruit fly when the mature larvae were exposed to treated soil. When untreated females were mated with males that had emerged from treated soil, the subsequent egg hatch was decreased. This decrease was retained longer with increasing J3230 concentrations. The number of spermatozoa in spermathecae of females mated with males that had emerged from treated soil was significantly reduced. Histological sections further showed aberrant flagella and sperm bundles in testes from the treated group. J3230 activity was reduced when the treated soil was incubated at 25, 35, and 45°C for extended periods; however, its activity could be retained in the soil for > 1 mo at 25 and 35°C. Short-wave length UV light (254 nm) and soil moisture were also found to affect the activity of this chemosterilant. |
