摘要
通过田间监测、室内生测等方法,研究了上海地区小猿叶甲的发生规律以及多种药剂对该虫的毒力大小及田间防治效果。结果表明:上海地区小猿叶甲一年发生3代,存在春秋2个发生高峰,设施栽培条件下可越冬,设施栽培和露地栽培发生规律相似;多种药剂对小猿叶甲室内毒力结果显示,0. 6%苦参碱的毒力最高,为0. 0781 mg/L,3%啶虫脒、2. 2%甲维盐和10%虫螨腈毒力次之,分别为0. 4824 mg/L、1. 7444 mg/L、2. 6286 mg/L,40%辛硫磷对小猿叶甲的毒力最小,为23. 0373 mg/L;田间防治试验结果显示,综合考虑药剂的速效性和持效性,0. 6%苦参碱6 mg/L、20%呋虫胺200 mg/L、10%虫螨腈100 mg/L、10%溴氰虫酰胺50 mg/L和60 g/L乙基多杀菌素60 mg/L防效较好,药后3—7 d的防效均达到95%以上。22%氟啶虫酰胺、20%啶虫脒和25%噻虫嗪药后3 d的防效也能达到90%以上,可与上述药剂轮换使用防治小猿叶甲。
The population dynamic of Phaedon brassicae Baly in Shanghai area,several kinds of insecticides to P. brassicae toxicity and field control efficiencies were investigated in both indoor and field tests. The results showed that the beetles reproduced three generations a year with two peaks in spring and autumn. The population dynamic of Phaedon brassicae Baly in greenhouse was similar with that in outdoor. The toxicity of 0. 6% matrine was the highest followed by 3% acetamiprid,2. 2% emamectin benzoate and 10% chlorfenapyr. And 40%phoxim had the least virulence to the beetles. Field control test results indicated that the control effects of 0. 6%matrine,20% dinotefuran and 10% chlorfenapyr,10% cyantraniliprole and 60 g/L spinetoram were better considering the rapidity of response and persistence of effect. 3-7 d after spraying the control effects had reached more than 95%. The control effects of 22% flonicamid,20% acetamiprid and 25% thiamethoxam could reach more than 90% after 3 days. These insecticides could be applied alternately to control the pests.
