摘要
狭冠网蝽是甘肃省云杉上发现的新害虫,为了给化学防治提供理论依据,选取2.5%功夫乳油、50%抗蚜威可湿性粉剂、20%氰戊菊脂乳油、2.5%溴氰菊脂乳油4种药剂进行药效试验。结果表明:2.5%功夫乳油3000倍溶液对成虫防治效果较好最好,药后防效达到了93.9%,2.5%溴氰菊脂乳油3500倍溶液防治效果最差;20%氰戊菊脂乳油3000倍溶液对狭冠网蝽若虫的防治效果最好。
Stephanitis angustata is a new pest found on Picea asperata in Gansu province. In order to provide theoretical basis for chemical control, compare with 2.5% Cyhalothrin cream, 50% Pirimicarb wettable powder, 20% Fenvalerate cream and 2.5% Deltamethrin cream. The result showed that the mortality of Stephanitis angustata adult amounted to 93.9% after 3 000 dilution of 2.5% Cyhalothrin cream, the least effective solution was 2.5% Deltamethrin cream, 3 500 times solution;the best control effect on the nymphal of Stephanitis angustata was 20% Fenvalerate cream solution of 3 000 times.
