1997～ 1 998年 ,应用二化螟性诱剂对越冬代二化螟进行了田间诱捕试验。结果表明 ,载体为橡皮塞的二化螟性诱芯田间诱杀持续期达 34d以上。每公顷设 30、45和 90个诱盆的诱杀区卵块量均比对照区下降 6 0 %～6 8% ,卵量下降 74% ,枯心率也随之下降
From 1997 to 1998, a field trapping experiment was carried out on the overwintering squamous stem borer, Chilo suppressalis (Walker). The results showed that the duration of the trapping and killing of the rice stem borer Chilo suppressalis with the carrier rubber plug was above 34 days. The number of eggs in the trapping area of 30, 45 and 90 larvae per hectare decreased by 60% ~ 68% and the amount of eggs decreased by 74% and the dry heart rate also decreased
