【摘要】以温室草莓中危害最严重的红蜘蛛为试验对象,分别选取除虫菊素和苦参碱2种生物农药及其混配药液(体积比1∶1),采用电动高压喷雾器对草莓叶片正反面进行喷雾,研究除虫菊素、苦参碱及其混配药液对草莓红蜘蛛的防治效果.结果表明,单独使用除虫菊素和苦参碱2种药剂对草莓红蜘蛛均有较好的防治效果;但是复配混用的效果更好,药后6d的虫口减退率和防治效果均在99％以上.在生产中,建议2种药剂复配混用.%The paper took the red mite,the most damaging pest to strawberry in greenhouse,as test object,two biological pesticides,such as pyrethrin and matrine,and their mixed solution (volume ratio 1 ∶ 1)were respectively sprayed to the front and back sides of strawberry leaf with electric high pressure sprayer,to study their control effects.The results showed that using pyrethrin and matrine alone had good control effect against red mite,but the control effect of the mixed solution was better.The worm reduction rate and the control effect were all above 99％at 6 days after the treatment.Therefore,in production,it is suggested to spray the mixed solution of two pesticides.
