摘　　要：[目的]筛选防治茶园斜纹夜蛾的高效药剂。[方法]采用喷雾和浸叶饲喂的方法,研究6种药剂对茶园斜纹夜蛾的田间和室内防效。[结果]茶园喷施药剂3和7d后,短稳杆菌防效分别为76.24%和88.09%;氟啶脲为58.82%和90.48%;氯虫苯甲酰胺为55.88%和84.13%。室内药效测定结果表明,所有供试药剂药效均优于田间药效。短稳杆菌药后1和3d防效分别为93.33%和100%;甜核·苏云金、氯虫苯甲酰胺和氟啶脲药后7d防效为100%;茶核·苏云金和苏云金杆菌药后14d防效分别为92.85%和100%。[结论]短稳杆菌具有高效性和速效性,是理想的防治药剂,值得推广;其余所有药剂都有高效性,但速效性较差,需在斜纹夜蛾发生早期施用。[Objective]To screen out efficient pesticides against S.litura in tea garden.[Method]By spraying and leaf soaking, the field and laboratory control effects of 6 insecticides on S.litura were determined.[Result]After 3 and 7 days of spraying, the control effect of Brevibacterium was 76.24% and 88.09%, respectively, Chlorfluazuron was 58.82% and 90.48%;Chlorantraniliprole was 55.88% and 84.13%.By laboratory efficacy test,the control effects of Brevibacterium were 93.33% and 100% respectively after 1 day and 3 days.After 7days, the control effects of SeMNPV&.BT, Chlorantraniliprole and Chlorfluazuron were all 100%.And 14 days,EgNPV&BT and BT were 92.85% and 100% respectively.[Conclusion] Brevibacterium is an ideal insecticides against S.litura because of its high efficiency and rapidity in field and laboratory. All other agents are all highly effective, but less rapid,so they could be applied in the juvenile stage of S.litura.
