摘　　要：使用化学农药导致烟粉虱抗性迅速增强,而生物源农药抗性增长缓慢,以农药的速效性、持效性作为判定指标,比较3种生物源农药对烟粉虱的防效。试验结果表明,2%苦参碱水剂1000倍液田间防效最佳,可推荐作为烟粉虱高效防治药剂,适宜大面积推广。the resistance of Bemisia tabaci to chemical pesticides increased rapidly,while the resistance of B.tabaci to bio-pesticides increased slowly.The quick-acting and persistent-acting of pesticide were used as indexes to compare the control efficacy of three bio-pesticides on B.tabaci.The test results showed that 1000 times liquid of 2%matrine aqueous solution had the best field control efficacy,which could be recommended as an efficient control agent for B.tabaci and suitable for large-scale promotion.
