选择不同杀虫剂、不同防治时期、施药方法和次数防治小麦吸浆虫的试验表明,在小麦吸浆虫化蛹率达50%时,应用50%甲胺磷乳油、50%甲基异柳磷乳油、50%对硫磷乳油和6%林丹粉剂配成毒土于麦田撒施,均可有效控制小麦吸浆虫危害,穗、粒被害率均比对照降低80%以上;在小麦吸浆虫成虫羽化始盛期,用55%林丹胶悬剂0.4g/66.7m2、0.6g/66.7m2防治,防效达91.86%、94.95%,在这几种杀虫剂中防效最好;小麦播种前施药防治小麦吸浆虫幼虫效果并不理想。小麦吸浆虫的药剂防治策略应是蛹期防治为主,成虫期扫残。
The experiment of choosing different insecticides, different control periods, application methods and the number of times to prevent and control wheat midge insects showed that 50% methamidophos EC, 50% 50% parathion EC and 6% lindane powder mixed with toxic soil in the wheat field spreading, can effectively control the harm of wheat midge, ear and grain damage rates were reduced by more than 80% over the control; With 55% Lindane suspension 0.4g / 66.7m2, 0.6g / 66.7m2 control, control effect of 91.86%, 94.95%, the best of these insecticides control effect; Larvae effect is not ideal. Synechocystis sp. Medicine control strategy should be based on prevention and treatment of pupal stage, adult stage of the disabled.
