利用赤眼蜂防治农林害虫在国内已有不少地区开始大量应用,并取得了显著的效果。但赤眼蜂在生产上能否大量推广,常与寄主卵的供应情况有直接关系。目前常用的繁殖赤眼蜂的几种寄主如柞蚕和蓖麻蚕,受地区、季节等条件影响较大,群众不能广泛饲养,有一定的局限性,这给赤眼蜂的大量应用和推广带来了困难。因此,寻找适应性强,群众能广泛大量饲养的繁殖赤眼蜂的新寄主,就成为生产上迫切需要解决的问题。
The use of Trichogramma to prevent and control agricultural and forestry pests in many areas in the country have begun a large number of applications and achieved remarkable results. But trichogramma in the production of a large number of promotion, often with the host egg supply has a direct relationship. At present, several species of Trichogramma species that are commonly used to breed Trichogramma, such as tussah and castor silkworm, are greatly affected by the regional and seasonal conditions and can not be widely reared by the public, which has some limitations. This gives a great deal of application and promotion of trichogramma It’s difficult. Therefore, it is urgent to find a new host breeding Trichogramma that is adaptable and can be widely and widely reared by the masses.
