我营自1972年开展赤眼蜂防治松毛虫的工作,由于缺乏冷藏设备,不能大量繁蜂,1973年蜂卡贮藏曾采用挖山洞、放冰块等办法,但因湿度大遭到霉烂变质,另因温差不能控制,出蜂羽化和放蜂期配合不上,造成不应有的损失。思想上负担很大,错误地认为没有冷藏设备,赤眼蜂生产不能轻易扩大。 1974年营党委帮助赤眼蜂试验小组总结经验教训,提出大胆试验,土法上马,克服冷藏难关的要求。试验组的同志遵照毛主席关于“穷则思变,要干,要革命”的伟大教导,根据柞蚕母蛾喜在夜间黑暗下产卵,光照对产卵有影响的现象分析,蛾脑和产卵是有联系的。如果切断联系是否会失去产卵作用?于是进行了摘头试验。结果是摘头后不能再产卵,寿命也普遍得到了延长。这一实验的成功,给繁蜂生产带来了很多好处:
I battalion since 1972 Trichogramma Trichogramma prevention and control work, due to the lack of refrigeration equipment, can not be a large number of bumblebees, storming in 1973 used to dig the cave, put ice and other methods, but due to humidity, mildew metamorphism, The other due to temperature control can not control the emergence of a bee feather and the bee do not match, resulting in undue loss. Considerable burden on the idea, mistakenly think there is no refrigeration equipment, Trichogramma production can not easily be expanded. In 1974, the party committee helped the Trichogramma trial group to sum up experiences and lessons and put forward the requirement of boldly testing, launching the native soil law and overcoming the difficulties of cold storage. The comrades in the experimental group followed the great teachings of Chairman Mao on “changing from poverty to wanting to revolution”. According to the analysis of the phenomenon that spawning of the tussah moth in the darkness at night and the light affecting the spawning, Eggs are linked. If the cut off contact will lose the role of spawning? The result is that after the first pick can no longer lay eggs, life expectancy has also been generally extended. The success of this experiment has brought many benefits to bumblebee production:
