摘要: 缨小蜂是假眼小绿叶蝉的主要卵寄生蜂,本文结合田间观察和室内实验,对缨小蜂的生物学特性进行了初步的研究。结果获知:缨小蜂成蜂的活动与温度、光照密切相关,该蜂可兼营两性生殖和孤雌生殖,但孤雌生殖未见雌性后代。在25℃条件下,缨小蜂从卵到成蜂羽化的发育历期为21.40±0.26 d,以10%蜂蜜水作为补充营养能显著延长雌蜂寿命。微小裂骨缨小蜂单雌平均怀卵量36.83±0.81粒,叶蝉三棒缨小蜂单雌平均怀卵量22.33±0.48粒。同时,采用共景深成像系统拍摄了2种缨小蜂各虫态发育过程及其形态特征。

Abstract: Investigations on the egg parasitoids of tea leafhopper, Empoasca vitis (Göthe), were conducted both at tea plantations and in laboratory of Fujian Agriculture & Forestry University, Fuzhou. Two dominant egg parasitoids, Stethynium empoasca Subba Rao and Schizophragma parvulas Ogloblin, in Mymaridae have been found in Fujian tea plantations. Studies on the biology showed that the adult activity, longevity and oviposition of the two mymarids were significantly affected by temperature and light. These two mymarids can reproduce in both ways of amphigony and arrhenotoky. Under 25℃ condition, the lifecycle from egg to adult emergence lasted for about 21.40±0.26 days. After 10% honey water solution was supplied as supplementary nutrition, the female longevity could be proplonged significantly. The average reproductive capacity in Schizophragma parvulas (about 36.83±0.81 eggs per female) was much more than which in Stethynium empoasca (about 22.33±0.48 eggs per female). The photomicrographs for general morphological characteristics of the two mymarids from egg to adult were provided as well.
