| Abstract: | The toxicity and efficacy of a new insect growth regulator keyouniao to Ostrinia furnacalis (Guenee) were tested. LC 50 of keyouniao to first and second instar of O furnacalis was 2 39 mg/kg , and the effect of inhibiting hatch ability of O furnacalis eggs was distinct The efficacy of the mixture No 4 of keyouniao with other insecticides against O. furnacalis was 94 2% in fields |
