摘　　要：采用水试管喂毒法,研究了唑虫酰胺对红火蚁(Solenopsis invicta Buren)工蚁行为的影响。5、10和20 mg/L唑虫酰胺处理10 h后,红火蚁小型工蚁死亡率分别为58.3%、97.5%和83.3%,显著高于对照组10%的死亡率,红火蚁中型死亡率分别为51.7%、86.7%和60.0%,显著高于对照组3.3%的死亡率。0、5、10、20 mg/L唑虫酰胺处理10 h后,红火蚁小型工蚁行走率分别为93.3%、31.7%、0、3.3%,抓附率分别为93.3%、21.7%、0、3.3%,爬杆率分别为93.3%、21.7%、0、3.3%;红火蚁中型工蚁行走率分别为96.7%、63.3%、8.3%、31.7%,抓附率分别为96.7%、46.7%、5.0%、20.0%,爬杆率分别为96.7%、55.0%、5.0%、26.7%。The effects of tolfenpyrad on the behavior of worker ants of Solenopsis invicta Buren were studied by using water tube to feed poison method.After 10 h treatment with 5,10 and 20 mg/L tolfenpyrad,respectively,the mortality rate of the small worker ants was 58.3%,97.5%and 83.3%,much higher than that of the control group with only 10%of the mortality rate.The medium mortality rate of red fire ants was 51.7%,86.7%and 60.0%,respectively,which was significantly higher than that of the control group with 3.3%.After 10 h treatment of 0,5,10 and 20 mg/L,the walking rates of small red imported fire ants was 93.3%,31.7%,0,3.3%,the grasping rate was 93.3%,21.7%,0,3.3%,and the climbing rate was 93.3%,21.7%,0,3.3%,respectively.The walking rate of red fire ants was 96.7%,63.3%,8.3%and 31.7%,the grasping rate was 96.7%,46.7%,5.0%and 20.0%,and the climbing rate was 96.7%,55.0%,5.0%and 26.7%,respectively.
