摘要
详细地描述了蚜虫的一种专一捕食性天敌———贵州食蚜瘿蚊本地品系的形态特征,并研究了它的生活习性。食蚜瘿蚊从卵到成虫的有效积温和发育起点温度分别为273. 82日度和8. 35℃。一头食蚜瘿蚊幼虫一生平均可杀死豌豆修尾蚜59. 6头。
The morphological and biological characters of Aphidoletes aphidimyza were studied in the laboratory in Guizhou.The developmental threshold temperature is 8.35℃ and the effective cumulative temperature is 273.82 day degree.
