【摘要】 【目的】研究褐足角胸肖叶甲的生物学特性,为害虫防治提供科学依据。【方法】2009～2011年采用室内饲养和大田系统调查法,对褐足角胸肖叶甲的生物学特性进行观察和研究。【结果】褐足角胸肖叶甲在广西南宁1年发生5代,世代重叠,3月底～4月初成虫开始活动,交配产卵,卵产于寄主根部10～15mm的疏松土层。成虫取食香蕉未完全展开的嫩叶和刚抽蕾的嫩果皮,严重影响香蕉叶片光合作用和果实的外观品质和商品价值。【建议】清除无用的吸芽苗、假茎枯叶和田边杂草,恶化害虫栖息环境;利用害虫的假死习性人工捕杀;适时采用化学药剂防治,并注意轮换用药。更多还原

【Abstract】 [Objective]The study was made to investigate the biological characteristics of Basilepta fulvipes fed on leaves and fruits of banana(Musa spp.) in order to develop scientific measures for its control.[Method]From 2009 to 2011,the biological charateristics of B.fulvipes were studied by laboratory breeding and systematic field investigations.[Result]Mating of B.fulvipes could be observed during late March and early April with 5 generations and overlapping generation each year in Nanning(Guangxi) .The eggs were laid in about 10-15 mm loosen soil in banana rhizosphere.Adult B.fulvipes fed on unexpanded young leaves of banana and its young pericarp,which severely affected the photosynthesis and the quality and commodity value of banana fruits.[Suggestion]The following measures for controlling B.fulvipes were recommended:(1) Removal of useless sucker plants,dead leaves and false stem of banana,and weeds in order to worsen the habitat of B.fulvipes;(2) Artificial killing according to the feign death habit of B.fulvipes;(3) Control and prevention of B.fulvipes alternatively by using chemical control agents.更多还原
