摘要
为了减少化学农药的使用,探索林业有害生物无公害防治新途径,推广新药剂药械,2009年在林间进行了应用撒布器施放阿维菌素、Bt、森得保粉剂灭虫药包防治落叶松红腹叶蜂试验。结果表明:森得保防治效果89.32%以上,阿维菌素防治效果82.26%以上,Bt防治效果86.25%以上;非靶性昆虫施药前后数量波动幅度小,对天敌杀伤力小;其防治成本是人工防治的2倍,但效率是人工防治的3倍,效益是人工防治的1.5倍。证明该产品对害虫具有较高杀伤力,对非靶性生物影响小;使用机动灵活,适合于山区地形复杂、人员不易到达地区的林业有害生物防治,能降低防治人员的劳动强度。
In order to reduce the use of chemical pesticides, explore new ways for non-pollution pre-vention of forestry pests and the promotion of new pharmaceutical, the experiment was carried out on the spray of pesticide bomb in-eluding Abamectin, Bt and Sendebon against Pristiphora erichsonii with dispenser in the forest in 2009. The results showed that control effect Sendebon of was 89.32%, control effect of avermectins was over 82.26% and control effect of Bt was more than 86.25%; non-target insects no toxicity; the development of insects are a normal state, the control cost is two times of the cost of artificial control, hut the efficiency is 3 times of artificial control, the efficiency is 1.5 times of the artificial control, the product of mass destruction pests have lesser effects on of non-target organisms; the flexi-bility for complex mountainous terrain, personnel is not easy to reach areas of forest pests and diseases control, preven-tion and treatment can reduce the labor intensity.
