摘要
为迅速控制金龟子等地下害虫的严重为害,采用灯光诱杀和低毒化学药剂防治相结合的技术,采取产研合作模式对金龟子等地下害虫进行治理。两年的大面积示范结果表明：金龟子的为害情况得到有效控制,蔗龟枯心苗平均相对防效达76.75%~82.17%;金龟子虫口密度下降率分别达69.47%和93.86%;可留宿根面积占当年收获面积比例分别提高到60.8%和64.32%;甘蔗平均单产、蔗糖分和产糖率均有不同程度提高。
This project aimed to control the considerable damage of the sugarcane beetle and other soil pests as soon as possible, and to achieve sustainable control purposes, by using light trapping and low-toxicity pesticides, being the cooperation of production and scientific research. After two years in large-scale demonstration ,the beetle damage has been effectively controlled. The results showed that the mean relative control effect of dead heart seedling caused by beetle was 76.75%-82.17%. The decline rates of beetle population density were 69.47% and 93.86% respectively. The proportion of the ratoon areas of the total harvested areas increased to 60.8% and 64.32% respectively. The average sugar cane yield, sucrose and sugar rates were increased in these two years.
