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、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。
為瞭尋找齣對荔枝蝽象(Tessaratoma papillosa Drury)高效、持效、安全的殺蟲劑，通過室內毒力試驗和田間藥效試驗研究7種殺蟲劑對荔枝蝽象的防治效果。結果錶明，30%敵百蟲乳油1000倍液和5%銳勁特懸浮劑2000倍液對荔枝蝽象成蟲的殺蟲效果最好、藥效最穩定，室內施藥後72 h時30%敵百蟲乳油1000倍液對荔枝蝽象成蟲的校正死亡率達到100%、5%銳勁特懸浮劑2000倍液對荔枝蝽象成蟲的校正死亡率達到98.35%，田間施藥後1、3、7天此2種殺蟲劑對荔枝蝽象的蟲口減退率和田間防治效果均在90%以上。其次10%吡蟲啉可濕性粉劑1000倍液、52.25%農地樂乳油2000倍液和2.5%敵殺死乳油3000倍液也錶現齣對荔枝蝽象良好的防治效果，室內施藥後72 h時10%吡蟲啉可濕性粉劑1000倍液對荔枝蝽象成蟲的校正死亡率為96.65%、52.25%農地樂乳油2000倍液對荔枝蝽象成蟲的校正死亡率為95.00%、2.5%敵殺死乳油3000倍液對荔枝蝽象成蟲的校正死亡率為93.35%；田間施藥後3、7天此3種殺蟲劑對荔枝蝽象的蟲口減退率和防治效果均達到90%以上。

To find out the high-efficiency, long time-efficiency and safe insecticides to the Tessaratoma papillosa Drury, 7 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 2 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 2 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.
