摘  要:
研究不同杀虫剂在不同时期对小麦吸浆虫的防治效果,结果表明:在秋季麦播前进行土壤处理,防效不理想;在吸浆虫蛹期、羽化高峰期防治虽能获得较好的防治效果,但需要专业技术人员掌握发育进度,不适合指导群防群治;而小麦抽穗70%~80%时,正值吸浆虫产卵始盛期,此期防治能获得事半功倍的效果,这一物候现象群众容易掌握,因此把小麦抽穗70%~80%作为吸浆虫的防治适期符合当前的生产现状。

摘  要:
Control effect of different pesicides to wheat midge in different periods was carried out.The results showed that the control effect of soil treated in fall before sowing wheat was not ideal.In the period of nymph stage and ecdysis peak,the control effect was better,but it needed highly professional technique and not suitable for guiding farmer to control the midges.The best control period was in wheat earing stage with 70%-80% wheat ears appear and the period of wheat midge laying ovals peak,because most adults ecdysising just before or after this period were not effective pest source and the biotemperature phenomenon was easy to grasp by most farmers.So,it is applicable that determining the period when 70%-80% wheat is coming into ear as the suitable control time under present production situation.
