摘　　要：为筛选防治蓟马的有效植物源杀虫剂,以缓解目前黄瓜生产中存在的适用杀虫剂品种少和抗药性严重等问题。对3种植物源杀虫剂的2个浓度梯度防效进行了大田比较试验。结果表明,1%苦参碱可溶液剂和0.5%藜芦碱可湿性粉剂的防效表现较好,药后7 d防效达90%以上,能够有效控制田间蓟马的为害。另外,苦参碱(500倍液)和藜芦碱(600倍液)低浓度施用时的防效与吡虫啉和多杀菌素等常用杀虫剂防效相当。苦参碱和藜芦碱均具有较好的速效性和持效性,可在早期发生较轻时代替吡虫啉等常规化学药剂,且生产上推荐使用低浓度用药量。Several effective botanical insecticides were screened out in order to alleviate the problems of few insecticides and serious resistance in current thrips control.The field trail of three botanical insecticides in 2 concentration gradients were conducted.The results suggested that 1%matrine soluble concentrate and 0.5%veratrine wettable powder displayed high effects,whose control effects could reach above 90%7 days later,indicating they were able to effectively control the damage of thrips.In addition,the control effect of matrine(500 times dilution)and veratrine(600 times dilution)at low concentrations were equivalent to that of commonly used insecticides such as imidacloprid and spinosyn.Matrine and veratrine had good quick-acting and lasting effect,both of which could replace chemical pesticides such as imidacloprid in the early mild stage.And low concentrations of these two insecticides were recommended to use.
