侧柏毒蛾Parocneria furva生物学特性及防治

侧柏毒蛾在福建一年发生3代,以卵越冬。幼虫5—6龄,幼虫期27—63天,蛹期8—22天,成虫寿命3—10天。每雌平均产卵量92粒。一般发生年份可于4月上旬在林间施放白僵菌粉炮,大发生时选用20％杀灭菊酯3000倍液、80%敌敌畏、50％甲胺磷1000倍液喷雾防治2—3龄幼虫,均有良好防治效果。

A STUDY ON THE BIONOMICS OF Parocneria furva AND ITS CONTROL

Parocneria furva Leech reproduces three generations in Fujian province and over-winters as eggs. There are 5 ?6 instars for the larve which last 27 ?63 days. Pupae last 8 ?22 days, and adult last 3 ?10 days. Female adults laies 92 eggs in average. Using Beauveria bassiana dust in April is effective to control when it emerging generally. At the time of serious e-merging year, spraying 1 : 3000 of 20% fenvalerate, 1 : 1000 of 80% DDV and 50% metharnidophos is effective.
