| 摘 要： | 通过室内饲养和田间定点观察的方法,对苦参野螟(Uresiphita prunipennis)的形态及生物学特性进行了调查研究。结果表明,苦参野螟在吉林市1年发生3代,以茧蛹在枯枝落叶下或表土中越冬。每年5月中旬越冬代成虫开始羽化,幼虫分别于6月上、中旬,7月中、下旬,8月下旬至9月上旬严重为害苦参,老熟后分散于地被物下或表土层中结茧化蛹。针对苦参野螟提出了防治建议。

| Abstract: | Morphological and biological characters of Uresiphita prunipennis (Butler, 1879) were investigated by the methods of indoor rearing and field fixed point observation. The results showed that U.prunipennis has 3 generations per year in Jilin, and overwinters as a pupa encased in a thick cocoon under the fallen leaves or the ground. The adult emerges in the middle of May while the larvae make great damage to Sophora flavescens in early/mid-June, mid/late July, late August or early September. The mature larvae move downward to the ground cover or pupate under the topsoil. The suggestion on control measures is also put forward |
