| 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. |
