1984—1987年在黑龙江、辽宁等4省9个市县,对松毛虫、杨毒蛾等7个虫种进行6274 ha大面积防治试验取得成功。不论地面和飞机防治均取得了90％以上的理想效果。灭幼脲Ⅰ号是抑制昆虫几丁质合成的药剂,经测定可抑制松毛虫几丁质合成达11—30％。该药能使昆虫在蜕皮或变态中产生障碍而致死。对人、畜安全;对环境无公害;对鱼类、鸟禽类、蜜蜂等均无杀伤作用。对天敌昆虫较安全,由于保护了天敌,增强了森林自控能力,促进了生态平衡。它是目前取代有机氯杀虫剂,克服害虫对有机磷和菊酯类抗药性的一种仿生药剂,可以在害虫综合治理(IPM)中广泛推广使用。
1984-1987 in Heilongjiang, Liaoning and other 4 provinces and 9 cities and counties, the Dendrolimus, Yang poison moth and other 7 species of large-scale control of 6274 ha success. Both the ground and aircraft control achieved more than 90% of the desired effect. Chlorbenzuron No. 1 is an agent that inhibits the synthesis of insect chitin. It has been determined that the synthesis of chitin in the pine caterpillars can be inhibited by 11-30%. The drug can make insects molt or metamorphosis in the resulting obstacles and death. It is safe for people and animals; it is harmless to the environment; it has no killing effect on fish, birds and birds, bees and so on. Natural enemies of insects more secure, due to the protection of natural enemies, enhance the ability of forest self-control, and promote ecological balance. It is currently a biomimetic agent that replaces organochlorine pesticides and overcomes the resistance of pests to organophosphorus and pyrethroids, and can be widely used in Integrated Pest Management (IPM).
