摘要： 为了寻找出对荔枝蝽象(Tessaratoma papillosa Drury)高效、持效、安全的杀虫剂，通过室内毒力试验和田间药效试验研究7种杀虫剂对荔枝蝽象的防治效果。结果表明，30%敌百虫乳油1000倍液和5%锐劲特悬浮剂2000倍液对荔枝蝽象成虫的杀虫效果最好、药效最稳定，室内施药后72 h时30%敌百虫乳油1000倍液对荔枝蝽象成虫的校正死亡率达到100%、5%锐劲特悬浮剂2000倍液对荔枝蝽象成虫的校正死亡率达到98.35%，田间施药后1、3和7天此2种杀虫剂对荔枝蝽象的虫口减退率和田间防治效果均在90%以上。其次10%吡虫啉可湿性粉剂1000倍液、52.25%农地乐乳油2000倍液和2.5%敌杀死乳油3000倍液也表现出对荔枝蝽象良好的防治效果，室内施药后72 h时10%吡虫啉可湿性粉剂1000倍液对荔枝蝽象成虫的校正死亡率为96.65%、52.25%农地乐乳油2000倍液对荔枝蝽象成虫的校正死亡率为95.00%、2.5%敌杀死乳油3000倍液对荔枝蝽象成虫的校正死亡率为93.35%；田间施药后3、7天此3种杀虫剂对荔枝蝽象的虫口减退率和防治效果均达到90%以上。

Abstract: To find out the high-efficiency, long time-efficiency and safe insecticides to the Tessaratoma papillosa Drury, seven kinds of insecticides were evaluated through both laboratory toxicity tests and field trials. The results showed the 1000 times of 30% trichlorfon EC and the 2000 times of 5% regent (fipronil) suspension possessed comparatively satisfied and stable effects on Tessaratoma papillosa Drury. After using these two pesticides in the laboratory for 72 h, the corrected mortality of Tessaratoma papillosa Drury adults amounted to 100% and 98.35% respectively. After using these two insecticides for 1 d, 3 d and 7 d in the field, Tessaratoma papillosa Drury's population decline rate and field control effect were above 90%. Also, the 1000 times of 10% imidacloprid WP, the 2000 times of 52.25% chlorpyrifos and the 3000 times of 2.5% deltamethrin EC showed a good control efficiency on Tessaratoma papillosa Drury, which could make the correct mortality reached to 96.65%, 95.00% and 93.35% respectively after used for 72 h in the laboratory. Meanwhile, the effects of these three insecticides on Tessaratoma papillosa Drury’s population decline rate and field control efficiency were above 90% after used for 3 d and 7 d in the field.
