摘　　要：应用刻度图示法研究了荒草地红火蚁Solenopsis invicta工蚁群体活动性规律.结果表明,最高爬升高度、平均爬升高度、工蚁恢复平静时间与蚁巢体积大小无显著相关;不同蚁巢被干扰后标尺上工蚁数量随干扰时间的延长,先快速增加,45～60 s时达到最大,随后缓慢减少直至标尺上无工蚁.通过分析建立了红火蚁工蚁平均数量与干扰时间关系的多个模型.提出了红火蚁工蚁活动性综合评价指标：工蚁活动性评价指标=工蚁累计数量×0.4＋工蚁最高爬升高度×0.1＋工蚁平均爬升高度×0.3＋工蚁恢复平静时间×0.2.Ruler-mark method was used to research the worker activity of red imported fire ant,Solenopsis invicta Buren,in wasteland in Shenzhen,Guangdong Province.The result showed that the highest and average heights which workers reached and the duration for workers to come back to silence on ruler had no significant correlation to mound volume.After different mounds were disturbed,the amount of workers on ruler increased quickly at first,reached the peak at time of 45-60 s,decreased slowly after then till no workers on ruler.Several models were constructed between the quantity of workers on ruler and time after disturbing.A integrated index was introduced to evaluate the activity of red imported fire ant worker,and its formula was：the accumulation of workers number× 0.4＋the highest reached height×0.1＋average height×0.3＋time consumption for workers to come back to silence×0.2.
