摘要
甘蔗细平象ＴｒｏｃｈｏｒｈｏｐａｌｕｓｈｕｍｅｒａｌｉｓＣｈｅｖｒｏｌａｔ是云南甘蔗上的一种毁灭性地下害虫，以幼虫和成虫在地下蔗头内为害，为害期８－１０个月。据１９８９年调查，受害蔗每亩损失５００—３０００ｋｇ，严重的无收。此虫１年发生互代，以成虫在蔗头内越冬，有喜湿性，不能飞翔，主要通过沟河流水传播。在河川坝地，沙壤土中虫口较多Ｚ宿根年限越长的甘蔗受害越重。建议蔗稻轮作；缩短甘蔗宿根年限；早春翻把有虫蔗烧毁；结合新植蔗下种，宿根蔗松培土施用甲基异柳磷或铁灭克等颗粒杀虫剂进行防治。
This paper reports the results of a study on the sugar cane weevil Trochorkopalut humeralic Chevrolat, the most destructive soil-inhabiting pest of the sugarcane stumps in Yunnan. The study was conducted mainly in Luxi County, Yunnan Province, during 1989- 1991. Data obtained from both laboratory observa,tions and field purvey show that the weevil passes one generation a year and over winters in adult stage in the host stumps. The biological characteristics and behaviour of the different stages are described. Recommended control measures are mainly agrotechnical practices such as crop rotation between sugarcane and rice, keep.ing off two-year old rhizome of ratoon which should be ploughed out and burned &lup in early spring (before mid March), etc. Applying insecticidal granules such as 3% Isofenphos-methyl or 5% Temik into the planting ditch near the host roots is also effective.
