在开展赤眼蜂防治松毛虫的试验工作中,我们根据柞蚕母蛾喜夜间黑暗下产卵,光照对产卵有影响的现象分析,认为蛾头和产卵是有联系的。设想,如果切断这种联系,是否会失去产卵能力?于是我们进行了摘头试验。经观察,摘头后,雌蛾即不能再产卵,寿命也普遍得到了延长,这给繁殖赤眼蜂,防治松毛虫,带来了很多好处。
In carrying out Trichogramma Trichogramma test work, we based on the tussah moth Xi night darkness spawning, light on the spawning phenomenon, that the moth head and spawning are linked. Imagine, if you cut off this link, will lose the ability to lay eggs? So we carried out the first test. After the observation, after removing the head, the female moth can no longer lay eggs, life expectancy has also been generally extended, which gives breeding Trichogramma, prevention and treatment of pine caterpillars, brought a lot of benefits.
