摘要
友恩蚜小蜂是松突圆蚧的重要优势寄生蜂,已广泛应用于松突圆蚧的生物防治。经2008年观察发现:在广东省惠东县大岭镇文布种蜂地,友恩蚜小蜂一年出现两个数量高峰,第一个高峰出现在3～6月,第二个小高峰出现在10～11月。在罗定市苹塘镇林间,友恩蚜小蜂一年发生11代,世代重叠。
As an important dominant parasitoid of Hemiberlesia pitysophila Takagi, Encarsia amicula Viggiani et Ren was extensively applied in biological controlling H. pitysophila Takagi. One year＇s investigation in Daling and Huidong indicated that the parasitoid had two population peaks, the first peak appeared from March to June, the second appeared from October to Novemeber. In the forest in Pingtang town, Luoding, there were 11 generations per year and overlap of generations was obvious.
