福建省烟粉虱寄生蜂的调查与常见种类鉴别

对福建省大田作物的烟粉虱寄生蜂种类进行调查,采获和鉴定寄生蜂6种,即:蚜小蜂科(Aphelinidae)的双斑恩蚜小蜂(Encarsia bimaculata)、日本恩蚜小蜂(Encarsia japonica)、索非亚恩蚜小蜂(Encarsia sophia)、蒙氏桨角蚜小蜂(Eretmocerus mundus)、瑞加桨角蚜小蜂(Eretmocerus rajasthanicus)和广腹细蜂科(Platygasteridae)的1种埃密细蜂(Amitus sp.),简述它们的形态鉴别特征。同时,从其他粉虱寄主或扫网等的调查中,还采获另外10种恩蚜小蜂和桨角蚜小蜂,根据国内外文献报道也可寄生烟粉虱,在此本研究一并进行了讨论。

Investigation of Bemisia tabaci Parasitoids and Identification of Their Common Species in Fujian Province of China

The parasitoids of Bemisia tabaci on the crops in Fujian province of China were investigated and identified. The six parasitoids of B. tabaci, e. g. Encarsia bimaculata, En. japonica, En. sophia, Eretmocerus mundus, Er. rajasthanicus(Hymenoptera: Aphelinidae), and Amitus sp.(Hymenoptera: Platygasteridae), were briefly described and illustrated. Moreover, the other 10 parasitoids of Encarsia and Eretmocerus collected from other whitefly hosts or by sweeping and yellow pan trap were dealt with and discussed in this paper, because they were recorded as parasitoids of B. tabaci in the literatures.
