木通食植瓢虫Epilachna clematicola的生活习性研究初报

木通食植瓢虫,因取食毛莨科宿根攀援草本小木通而得名,目前已知分布于云南省的昆明、安宁、武定等滇中温暖地区及滇东南丘北等地。木通食植瓢虫成虫及幼虫取食小木通营养叶,发生多时能致寄主植物枯萎。此虫食性专一,是庭园、道旁、苗圃、菜圃等主要杂草小木通的有效控制因素。木通食植瓢虫成虫产卵及老熟幼虫化蛹都在寄主的叶片上。在昆明及其附近,木通食植瓢虫一年两代,以成虫在干缩叶片中、落于地被物中越冬。本文述及各虫态的经过及习性。对木通食植瓢虫的保护利用,是控制杂草小木通的途径。

A PRELIMINARY STUDY ON THE LIFE HISTORY AND HABITS OF Epilachna Clematicola(COLEOPTERA,COCCINELLIDAE)

Epilachna clematicola is the monophagus insect of the weed-Clematis armandii. The adults and larvae feed on the fresh leaves of this weed and wither up the plant. Eggs are deposited and the full grown larvae pupate on the leaves of the plant. The ladybeetle has 2 generations a year in Kunming and its vinicities. It overwinters in the crevices of the earth during adult stage with the twisted leaves. In this article, bionomics of all stages of the insect are given briefly. Epilachna clematicola shoald be protected and utilized as a kind of biological control agent of the weed-Clematis armandii.
