利用赤眼蜂防治农作物和森林害虫在省内外已广为应用,成为农林生产上防治害虫的一项重要措施。赤眼蜂在生产上的大量被利用,与育蜂有着直接的关系,其关键则在于育蜂寄主。目前赤眼蜂应用最广泛的育蜂寄主是蓖麻蚕,但有它的局限性:在我省的气候条件下,以蓖麻叶养蚕须到五月初才有叶子供应,特别是稻螟赤眼蜂不能在蓖麻蚕卵上寄生,给大量繁殖这种卵蜂带来一定困难。一九七二年我们在临武县汾市公社南岸大队黑光灯下发现,桑灰灯蛾是赤眼蜂的较好寄主,它的卵几种赤眼蜂都喜欢寄生,特别是二化螟猖獗,需用稻螟
The use of Trichogramma repellent to control crops and forest pests has been widely used inside and outside the province and has become an important measure for pest control in agriculture and forestry. Trichogramma is widely used in production, and has a direct relationship with the breeding of bees, the key lies in the breeding bee host. At present, Trichogramma is the most widely used silkworm bee host, but it has its limitations: in the province’s climate conditions, the sericulture of ricinus leaves has no supply until the beginning of May, especially the rice borer Trichogramma can not parasitize eggs in the castor silkworm eggs, to give birth to a large number of breeding this egg bee certain difficulties. In 1972, we found that black moth was the best host of Trichogramma under the black light in the south bank of Fen commune in Linwu County. Its eggs had many parasites, especially Trichogramma Rampant, need to use rice borer
