枣掌铁甲生物学特性研究

Study on the Biological Characteristics of Platypria melli

通过野外采集和室内饲养的方法,对枣掌铁甲的生物学特性,包括其寄主植物、潜道特征、各虫态特征及其生活史进行了系统研究。结果表明:枣掌铁甲在江西省井冈山地区1a发生1代,以幼虫潜食鼠李科枳椇叶片,老熟幼虫在叶脉处形成U型蛹室准备化蛹;枣掌铁甲形成不规则斑块状潜道,严重影响叶片的光合作用。该研究可为枣掌铁甲的预报和防治提供理论基础。

Biological characteristics of Platypria melli Uhmann （Coleopotera. Hispidae） were systematically studied and their host plant, leaf mine, larva morphology, pupa morphology and life history were described in detail. The results showed that it had one generation per year in Jingangshan of Jiangxi, P. melli larva mined in the leaves of Hovenia acerba Lindl. （Rhamnaceae） and mature larva would make a U-shape mine near main vein to pupate. P. meUi made irregular blotch mines,which seriously affected leaf photosynthesis. Theoretical bases had been provided for the prediction and control of P. melli.
