在我们大队,粟灰螟是造成谷子减产的主要害虫。为把害虫密度压低到不致使作物受害而减产,我们总结了过去防治害虫的经验教训,提出了以防治粟灰螟为主的综合防治措施。刨烧谷茬粟灰螟在谷草和谷茬中越冬,据前年春调查,百茬含虫3.2头,占越冬虫数的91.4%。只要彻底刨烧谷茬,就可大量消灭虫源,减轻田间虫害发生。用拖拉机耕地、人工刨茬,一般是先耕地后拾茬,不易拾净。秋深耕时把谷茬埋入土中,有利于害虫越冬,春浅耕时再把谷茬翻出来,又有利于害虫羽 In our brigade, the rice borer is the main pest that causes the reduction of millet production. In order to reduce pest density to a level that will not cause crop damage, we summed up the experiences and lessons learned from pest control in the past and put forward the integrated prevention and control measures based on the control of the corn borer. Burning stubble corn stalk Smolders and winter stubble wintering in winter, according to the survey of the previous spring, stubble contained 3.2 insects, accounting for 91.4% of the number of wintering insects. As long as thoroughly burned stubble, you can eliminate a large number of insect sources and reduce pests in the field. Tillage with tractors, manual planing, usually after the first plow of cultivated land, not easy to pick up the net. Autumn deep plowing the stubble buried in the soil, is conducive to pests overwintering, spring tillage and then stubble out, but also conducive to pest feather
