摘要
蔗根土天牛[D ory sthenes g ranu losus(T hom son)]是甘蔗主要地下害虫之一,近年来危害日趋严重。成灾原因主要是由于种植方式过于单一,防治意识淡薄,甚至不采取防治措施。了解其形态特征、生物学特性,采取综合防治方法,特别是利用有益生物绿僵菌(M etarrh iz ium an isop liae)及昆虫病原线虫防治天牛有较明显的效果。但在田间使用时受环境影响较大,尚需深入进行研究;灯诱成虫,消灭虫源,也是十分重要的防治措施。
Dorysthenes granulosus (Thomson) is one of important soil insect for sugarcane, which caused deeply damage to sugarcane in recent years. The reasons of damage are mainly because that the planting fashion of sugarcane is too unitary, the consciousness of control is weak and even don't take any measures to control by the growers. Integrated control should be taken to control D. granulosus by knowing about its morphological character and biological characteristics, and to apply beneficial organism such as Metarrhiziurn anisopliaeare and entomopathogenic nematodes which could have an obvious effect, but it is affected by environment in field and still needs to study deeply. To induce the imago by lamp and to eliminate sources is also a very important measure in controlling the pest.
