【摘要】 通过野外防治实践,最终筛选出了适合防治不同种类园林刺吸式害虫的高效低毒农药种类:防治蜡蝉类刺吸式害虫可考虑用敌杀死和印楝素;防治蚜虫类刺吸式园林害虫可优先考虑用蚧宝、蓟蚜虱净、百虫杀;防治网蝽类园林刺吸式害虫可考虑应用吡虫啉[3]、苦参碱、阿维菌素、敌杀死等4种农药;防治螨类园林植物刺吸式害虫时可考虑应用阿维菌素、苦参碱及克螨净这3种高效低毒化学农药及生物农药。防治时具体施用浓度需根据害虫的种类、寄主种类、使用时间及环境条件来确定。更多还原

【Abstract】 Experiments to control phloem-sucking pests in landscaped forests by high efficiency and low toxicity pesticides was carried out,it indicated that: pesticides such as Deltamethrin and azadirachtin have good control effects on plant hopper,Methidathion,acetamiprid and nicotine also have effects on plant louse.But pesticides imidacloprid,matrineand,avermectins and deltamethrin have effects on lace controlling and avermectins,matrine and pyriden have effects on mites controlling.The control density of different pesticides should be chosen according to the species of pests and hosts,application time and environmental condition.更多还原
