摘　　要：通过室内饲养和田间调查,对香蕉褐足角胸叶甲的形态特征及生物学特性进行观察和研究。结果表明,褐足角胸叶甲在云南省河口县一年发生3代,世代重叠,以幼虫在土中越冬,次年3月中下旬在土中化蛹,其中8月下旬成虫最多。褐足角胸叶甲卵多为聚产,主要产于表土层和枯枝落叶下,每块有卵6～30粒,有的多达60多粒。卵约经过7.95天后开始孵化,最迟12.54天后孵化。The biological characteristics of Basilepta fulvipes were studied by laboratory breeding and field investigations. Larva of B. fulvipes could be observed to overwinter in soil and pupate during late March with 3 generations and overlapping generation each year in Hekou, Ytmnan province. The eggs were laid in surface soil and old leaves, mostly together. The numbers of eggs were from 6 to 30, maximum to 60. The eggs began to hatch after 7.95 days, the last after 12.54 days.
