摘要
双纹须歧角螟TrichophysetiscretaceaButler是茉莉花的重要害虫之一。对它的生物学特性、生活史以及防治进行了研究。该虫在广西南宁年发生 1 4代 ,幼虫有 4个龄期 ,完成 1个世代需 1 4～ 2 2d ,其中产卵前期 2～ 3d,卵期 2～ 4d ,幼虫期 5～ 1 0d ,蛹期 5～ 8d。世代重叠 ,发生高峰期在 6～ 9月。采用综合防治方法 ,其中包括使用阿维菌素系列农药效果较好。
Trichophysetis cretacea is an important pest of Jasmine. The bionomics, life history and control methods for this pest were studied. This borer insect had fourteen generations a year in Guangxi and needs 14 to 22 days to complete one generation. The larval stage consists of four instars. The duration of the preoviposition stage is 2 to 3 days, that of the egg stage 2 to 4 days, the larval stage 5 to 10 days, and the pupal stage 5 to 8 days. Generations overlap. Peak occurrence is from June to September. Effective control methods are discussed.
