米螟Corcyra cephalonica Stainton是仓库害虫之一,现已用来繁殖赤眼蜂、草蛉等.利用赤眼蜂防治农林害虫,在我国广为应用,并取得一定成效.在赤眼蜂大量繁殖工作中,必须具备有大量中间寄主(即鳞翅类的大粒卵和小粒卵)、人工模拟卵和悬滴培养液.目前,在育蜂中最常用的中间寄主有蓖麻蚕、柞蚕和米螟.但是,我省闽北地区蓖麻蚕和柞蚕在饲养繁殖中都存在一些具体问题.因此,有必要另外寻找中间寄主米螟.1977年我们向广东移植米螟,并与当地仓库蛾类进行筛选.1977～1979年我们在沙县对米螟生活习性及繁殖技术进行研究,现把其结果整理如下.
Corn borer Corcyra cephalonica Stainton is one of the warehouse pests, is now used to breed Trichogramma, tadpoles, etc. The use of trichogramma pests control of agriculture and forestry, widely used in our country, and achieved some success in Trichogramma multiplication , There must be a large number of intermediate hosts (lepidopteran large-sized eggs and small-sized eggs), artificial mimic eggs and hanging drop culture medium.At present, the most commonly used intermediate host in breeding bee silkworm, tussah and rice beetles However, there are some specific problems in feeding and breeding of the castor silkworm and tussah in the northern Fujian province, so it is necessary to find the intermediate host rice borer in 1977. In 1977, we transplanted the rice borer to Guangdong and performed with the local warehouse moths Screening 1977 to 1979 we Shaxian rice borer living habits and breeding technology research, the results are summarized below.
