摘　　要：为了明确褐足角胸叶甲主要生物学特性，采用田间系统调查和室内饲养的方法，对玉米田褐足角胸叶甲成虫、幼虫、蛹的消长动态、成虫产卵习性及其生活史进行了研究。结果表明，褐足角胸叶甲在河北省保定、石家庄一年发生1代，以幼虫在5～15cm土层中越夏、10～15cm土层中越冬；次年4月，随着日期的推移，气温逐步升高，越冬幼虫从下部土层逐步向上移动至0～5cm土层，6月中旬在土中开始化蛹，蛹发生期长达40d；卵产在距地表1～3mm的表土层，或产在干枯的玉米叶片上，散产或呈块状，少的2～3粒，多的一块卵达32粒。In order to determine the main biological characteristics of Basilepta fulvipes, we investigated the population dynamics of adults, larvae, pupae, and adult oviposition habits and life history of Basilepta fulvipes by using the methods of field systematic investigation and rearing observation in laboratory. The results showed that Basilepta fulvipes has one generation per year in Baoding and Shijiazhuang regions of Hebei Province. The larvae over- summer in the soil layer of 5--15 cm and overwinter in the soil layer of 10--15 cm. In April the next year, with the gradually increase of air temperature, the larvae of Basilepta fulvipes moved from lower soil layer to upper soil layer of 0--5 cm. In mid-June, the larvae began to pupate in soil, and the pupae stage could be up to 40 days. The eggs were laid in the topsoil layer of 1--3 mm or on dry corn leaves, scattered or massive laid with 2 -3 eggs or32 eggs.
