In order to investigate the effects of cyantraniliprole on the behavior and lethality of the worker ants of Solenopsis invicta,cyantraniliprole solutions with the concentrations of 1 mg/L and 5 mg/L were used for the experiments. Lethal effect of cyantraniliprole on Solenopsis invicta was investigated by water tube method. The result showed that after 12 hours of treatment,corrected mortality rates of the worker ants were 34.74% and 62.82% at the extract concentration of 1 mg/L and 5 mg/L respectively,which were higher than that of the mortality of control (16.67%). Treated by 0 mg/L,1 mg/L and 5 mg/L for 12 hours,the corrected grabbing rates were 80.00%, 68.05% and 30.43%,respectively the corrected climbing rates were 80.00%,58.45% and 30.38%,the corrected walking rates were 91.67%,70.97% and 0,the walking speed were 2.07 cm/s,1.07 cm/s and 0,respectively the corrected aggregation rates were 92.86%,86.35% and 39.40%,respectively. These results indicate that cyantraniliprole possesses lethal effect against the worker ants of Solenopsis invicta under indoor conditions,which can inhibit behaviorial function of the worker ants of Solenopsis. Cyantraniliprole is a promising chemical ageut against Solenopsis invicta become the new chemical agent to control Solenopsis invicta.%为了研究溴氰虫酰胺对红火蚁工蚁的致死作用及活动能力的影响,采用水试管法测定溴氰虫酰胺对红火蚁工蚁的毒杀活性和行为影响.结果表明,1 mg/L和5 mg/L溴氰虫酰胺处理12 h后,工蚁校正死亡率分别为34.74%和62.82%,高于0 mg/L对照(16.67%).0 mg/L(对照)、1 mg/L和5 mg/L处理12 h后,工蚁校正攀附率分别为80.00%、68.05%和30.43%,校正抓附率分别为80.00%、58.45%和30.38%,校正行走率分别为91.67%、70.97%和0,行走速率分别为2.07、1.07 cm/s和0,校正聚集率分别为92.86%、86.35%和39.40%.溴氰虫酰胺对红火蚁工蚁具有较好的毒杀活性,可显著抑制工蚁的行为活动能力,在红火蚁防控中具有广阔的应用前景.
