摘要
选用0.26%苦参碱水剂、1.8%阿维菌素乳油、0.3%印楝素乳油和2.5%高效氯氰聚酯乳油防治酸枣食芽象甲,结果表明:除对照(2.5%高效氯氰聚酯乳油)外,0.26%苦参碱水剂600倍液和1.8%阿维菌素乳油的防治效果明显,1.8%阿维菌素乳油持效性较好,大田药效试验3 d后防效达到73.08%,对酸枣食芽象甲的取食行为有较好的抑制作用,生产中可以大面积推广应用。
The control effects of three biological pesticides on Scythropus yasumatsui were investigated： 0.26% aqeous matrine, 1.8% abamectin EC, 0.3% azadirachtin and 2.5% of high-performance polyester closantel EC. The results showed that except for referencing pesticide （2.5% of highkperformance polyester closantel EC）, 0.26% aqeous matrine and 0.3% azadirachtin had better effects to control S. yasumatsui, 1.8% abamectin EC had better lasting effect. In field efficacy experiments, the control efficiency was still 73.08 % three days after using abamectin EC, which exhibited better antifeeding effect on S. yasumatsui, indicating that abamectin EC can be used in large area in production.
