Abstract
Basic data on adult Asian corn borer (ACB), Ostrinia furnacalis (Guenne), emergence pattern and mating in support to IRM plan for Bt corn in the Philippines were generated under laboratory conditions and using small cage technique in the field. The emergence pattern of laboratory-reared adult ACB shows that the moths emerge in the early evening and peaked between 8:00 to 10:00 p.m. In the cage experiments in the field, the emergence pattern of adult ACB started in late afternoon, increasing at dusk, and peaked at about 8:00 p.m. for the female and between 8:00 and 9:00 p.m. for the male, and declined as it approached midnight. More males than females emerged from corn plants infested at 30 days after planting (DAP) and 40 DAP, although more individuals emerged from 40 DAP plants. The results did not show significantly different emergence patterns between male and female moths in both laboratory and field cage experiments. There is strong support or basis for random mating of ACB in the field, which reduces the risk of asynchronous emergence of ACB, if it ever happens, in Bt corn and refuge fields, within an Insect Resistance Management (IRM) program.
