| 摘 要： | 双斑恩蚜小蜂EncarsiabimaculataHeratyetPolaszek是烟粉虱Bemisiatabaci(Gennadius)的主要寄生性天敌之一。作者对双斑恩蚜小蜂的形态特征进行了描述。在实验室条件下,对双斑恩蚜小蜂的生活习性、寄生行为进行了观察。双斑恩蚜小蜂成蜂26℃时平均寿命约为7d,每雌产卵量273粒,雌蜂比例占据绝对优势,雌雄性比约为8∶1。双斑恩蚜小蜂的寄生过程大致分为寄主定位、寄主检查、穿刺、产卵、清扫、梳理和休憩等几个阶段。

| Abstract: | Encarsia bimaculata Heraty et Polaszek is one of the dominant parasitoids of Bemisia tabaci (Gennadius) in China. The morphological characters of En. bimaculata were described in this paper. The observation of life habits showed that the average longevity and fertility of En. bimaculata adult at 26℃was about 7?d, 27.3 eggs per female, and the sex ratio of ♀∶♂ was about 8∶1, respectively.The parasitizing behavior and life habits of this wasp were observed in the laboratory.The parasitizing behavior included host location, host examination, ovipositor probing and drilling,oviposition, cleaning and rest, etc. |
