这些卵很快孵化成幼虫。
因为通常只有一只雌性在一个特定的幼虫中产卵，所以它只会产生一只雄性，因为这只雄性可以在孵化时使它所有的姐妹受精。
Since only one female usually lays eggs in a given larva, it would pay her to produce one male only, because this one male could fertilize all his sisters on emergence.
这样，那些没有被寄生蜂寄食的虫卵的幼虫在孵化出来后，会食用自己卵的剩余部分，也吃下了那些致命的病毒。
After hatching, any pest larvae that have not been parasitised feed on the remains of their eggs and ingest the lethal virus.
