摘　　要：对甘蔗异背长蝽(次年的主要虫源)越冬卵的分布场所、不同越冬场所的孵化进度及若虫在蔗株上的分布规律,作了调查分析。对药剂防治策略和技术进行了全面的研究,提出了“主攻甘蔗异背长蝽,兼治甘蔗二点螟,狠抓一代低龄若虫防治”的策略,并采用敌敌畏加杀虫双混合液,集中喷施蔗苗心叶及基部叶鞘间隙的防治技术。经1991年在100 ha蔗田防治示范和1992年在1044.7ha大面积推广应用,收到了“一次施药,控制全年危害”的明显效果。每年每公顷可节省农药和用工费194元,每公顷增鲜蔗7980～10620kg,含糖量绝对值提高0.81％～0.85％,经济效益显著。The Distribution places of hibernating eggs of Cavelerius sacchrivorous, their hatching speeds in various places, and the distribution pattern of their nymphs in sugarcane were investigated and analyzed. On the above basis the control strategy and technique were proposed, that is, control mainly of C, Sacchrivorous, concurrently of Chilo in fusecatellus snellen, Vigorous measures to control the first instar nymphs of C. sacchrivorous of the first generation, and mass spray of the solution of dichlorvos (DDVP) mixed with.Upon the heart leaves and intervals of foot leaf sheathes of sugarcane seedlings. The effectiveness of the strategy and technique, was obvious which was proved by spraying the mixed solution once a year but controlling the damage through the year in the demonstration control in 100 hectares of sugarcane fields in 1991 and in the extended application in 1066.7 hetares of sugarcane fields in 1992. For per hectare per year, 194 Yuan of pestcide and labor costs could be saved; 7980～10620 kilograms of fresh sugarcanes could be increased; and 0.81～0.85% of absolute sugar content could be raised.
