赤眼蜂是一种卵寄生蜂,自然群落常是分散的,在田间、林区和果园等地飞翔活动,寻找寄主卵,利用其产卵针管产卵寄生于许多种害虫卵内,使害虫卵的胚胎不能发育,从而取得消灭害虫的效果。赤眼蜂卵在害虫卵内进行胚胎发育,然后经过幼虫期、予蛹期和蛹期,生长发育到成虫,羽化后的赤眼蜂咬破寄主卵卵壳,从出蜂孔中爬出来,进行其成虫期的活动。由此可见寄主卵就是赤眼蜂发育的外界环境,也就是赤眼蜂生长发育的小生态环境。近年野外调查研究已证实杨雪毒蛾(柳毒蛾)卵、茶白毒蛾卵、蔚茸毒蛾卵和茶茸毒蛾
Trichogramma is an egg parasitic wasp, the natural community is often dispersed in the fields, forests and orchards and other places flying activities, looking for host eggs, the use of their spawning needle spawning parasitic eggs in many species of pests, the pests Egg embryos can not develop, so as to achieve the effect of eliminating pests. Trichogramma eggs in the pest eggs for embryonic development, and then after the larval stage, to the pupal and pupal stages, the growth and development to adults, eclosion after the trichogramma biting the egg egg shell, climb out from the bee hole, Carry out their adult stage activities. This shows that the host egg is the development of Trichogramma outside the environment, that is, Trichogramma growth and development of small ecological environment. In recent years, field studies have confirmed that the snow Xueye moth (Liunis moth) eggs, tea white poison moth eggs, velvet moth eggs and tea velvet moth
