甘蔗异背长蝽是甘蔗的重要害虫,在江西泰和县一年发生完整的二代,部分三代,主要以卵在蔗蔸、土表层、枯鞘残茎和蔗种叶鞘内越冬,尚有少部分成虫在宿根蔗蔸和枯鞘叶中过冬。全年有两个为害严重期,第一次在五六月甘蔗苗期,第二次在八九月甘蔗伸长期。一代若虫孵化较整齐,且低龄若虫集中在心叶内吸食,是药剂防治的关键时期。成虫多群集在蔗株下部枯鞘与蔗茎间隙内栖息、取食和交配。卵成块产于叶鞘边缘内侧,以叶鞘抱茎松紧度适中的叶位分布最多,二代成虫9月间产的卵,当年可以孵化并发育为三代成虫越冬;10月初以后产的卵,当年不再孵化而滞育越冬。
Sugarcane long-legged Lygus is an important pest of sugarcane. In Taihe County of Jiangxi Province, a complete second generation and some three generations occur in winter, mainly with eggs in wintering in the sheath of sugarcane, soil surface, Some adults live in winter in cane mulching and dusky. There are two serious damage throughout the year, the first time in May and June sugarcane seedling stage, the second time in August and September cane elongation. A generation of nymphs hatch more neat, and nocturnal nymphs concentrated in the heart leaf absorption, is a key period of drug control. Adult multi-cluster habitat, feeding and mating in the lower sheath of the cane and the cane stem space. Eggs into pieces in the leaf sheath edge medial to the leaf sheath embolism tightness of the leaf position most distribution, the second generation of adult eggs produced in September, the year can be hatched and developed into three generations of adults overwinter; early October after the egg, the year No longer hatch diapause winter.
