1975～1985年,在赤眼蜂体外培育过程中,用同一培养基培养了10种赤眼蜂。试验表明:培养基的选择与蜂种的差异无关。体外培育的成功率取决于赤眼蜂雌蜂能否在人造寄主卵上产卵,以及产卵量的多少,这就决定于各种赤眼蜂产卵管的大小及产卵行为。我们清楚地观察到,赤眼蜂雌蜂每穿刺一次人造塑料卵所产下卵的多少是不同的,每完成一次穿刺和产卵所花时间也是不同的。在人造寄主卵中产的卵越多,培养基可被蜂幼吃的越多,营养充 From 1975 to 1985, Trichogramma was cultured in the same culture medium in vitro. The experiment shows that the choice of medium has nothing to do with the difference of bee species. The success rate of in vitro culture depends on whether or not Trichogramma can lay eggs on the artificial host eggs and how much they lay, which is determined by the size and oviposition behavior of various Trichogrammas. We clearly observed that the number of eggs laid by Trichogramma was different for each piercing of an artificial plastic egg and the time spent per lancing and spawning was different. The more eggs produced in the artificial host egg, the more the medium can be eaten by the bee, nutrition charge
