戴云鳃金龟是甘蔗上的重要地下害虫之一,以二、三龄幼虫越冬。5月上旬至7月下旬是甘蔗苗期和伸长期,也是三龄幼虫严重为害时期。发生地区的植被组成,产卵及孵化期内的降雨量和土壤水分是影响种群分布和种群数量分布以及种群变动的主要因素。越冬二龄幼虫春季要上移为害,夏季三龄幼虫在伸长期为害,因此,必须抓好下种期和低龄幼虫两次防治。采用50％辛硫磷,亩用0.6～0.75kg;3％甲基异柳磷、3％地虫磷颗粒剂,亩用4～5kg,有明显的治虫增产效果,已在生产中应用。
Dai Yun gill beetle is one of the important underground pests on sugarcane, with the second and third instar larvae overwintering. Early May to late July is sugarcane seedling and elongation, but also the third instar larvae seriously damaged period. Vegetation composition in the area of occurrence, rainfall during the spawning and hatching periods and soil moisture are the main factors affecting population distribution, population distribution and population changes. Overwintering second instar larvae to move up in the spring, the third instar larvae in the summer elongation damage, therefore, must do a good job of the next seedling stage and two prevention and control of larvae. The use of 50% phoxim, mu with 0.6 ~ 0.75kg; 3% methyl isofenphros, 3% comfrey phosphorus granules, mu with 4 ~ 5kg, there is a clear effect of pest control, has been applied in the production.
