对外来入侵植物薇甘菊天敌昆虫安婀珍蝶的生物学及其寄主专一性进行了研究。在温度2 6℃、RH80 %的人工气候箱内饲养 ,安婀珍蝶一个世代历期 92～ 1 0 2d,卵产于薇甘菊叶片上 ,幼虫在四龄前群聚生活 ,六龄后在支持物上化蛹 ,蛹期约 1 1d ,成虫存活约 8d。选择 42科 86种植物进行寄主专一性测定 ,结果表明 :安婀珍蝶对薇甘菊的嗜食程度明显高于其他供试植物 ,且仅能在薇甘菊、飞机草上完成世代
The biology of the invasive alien plant Myzus and its host specificity were studied. In the temperature of 26 ℃, RH80% of the artificial climate box feeding, Andelinaceae a generation of 92 ~ 102d, eggs produced in the leaves of Mikania micrantha, the larvae in the age group before the age of four, six years after the support The material on pupation, pupal period of about 1 1d, adult survival of about 8d. Host plants of 86 families and 42 families were selected for host specificity test. The results showed that the feeding preference of A. chinensis to Mikania micrantha was significantly higher than that of other tested plants, and only the generation of Mikania micrantha
