在赤眼蜂体外培育中,由于人工蜡卵不具备自然卵壳保湿和透气的特性,在悬滴制片中发育的赤眼蜂多因氧气不足、水份调节差、营养过剩,多数幼虫不能化蛹,长期“泡”在培养液中,不再发育,且易于长霉;能发育成蜂的,也因蜂体沾满粘稠的培养液,影响展翅与活动。反之,若培养液过少,则不能满足其需要而干瘪死亡。其次,接蜂时蜂数多,每腊卵中的产卵数亦多,蜂卵过多,则不利于子蜂的发育,也极易长霉。因此有必要摸清蜂幼虫数与培养液量的最适比例以及通气需求。
Trichogramma cultured in vitro, artificial wax eggs do not have the natural moisturizing and breathable egg shell characteristics, Trichogramma developed in the hanging drop film due to lack of oxygen, poor water regulation, excess nutrients, the majority of larvae can not Pupae, long-term “bubble” in the culture fluid, no longer develop, and easy to mold; can develop into bees, but also because of stained with a thick bee culture medium, affecting the wings and activities. Conversely, if the culture solution is too small, it can not meet its needs and died of death. Second, the number of bee-bee-receiving beehives and the number of eggs laid per litter are also large. Therefore, it is necessary to find out the optimum proportion of bee larvae and the amount of culture fluid and the ventilation needs.
