1973年,湖北省随县采集避债蛾(蓑蛾)茧共8万多头,饲养金小蜂120万头,释放在1,000多个生产队棉仓内,防治红铃虫的死亡率达80％以上。具体做法是: 采集树上悬挂的避债蛾茧,选取雄茧备用。因雌茧内幼虫皮厚,金小蜂不易寄生。一般雌茧比雄茧大三分之一,雌茧黑褐色,雄茧黄白色,雌雄幼虫的体色均与其茧色一致,可作区别。
In 1973, a total of more than 80,000 cocoones of shelter moths (moths) were collected in Suixian County, Hubei Province. There were 1.2 million golden beekeepers and more than 1,000 production team cotton bins. The mortality rate of red bollworm was 80 %the above. The specific approach is: collecting hanging trees hanging moth cocoon, choose the cocoon standby. Because of female cocoon larvae thick, golden bees are not easy parasitic. Female cocoon generally one-third larger than male cocoon, dark brown cocoon, male and female cocoon yellow-white, male and female larvae body color are consistent with the cocoon color, for distinction.
