摘　　要：2017年4月29日至2019年2月19日对西昌市的红火蚁(Solenopsis invicta Buren)蚁巢数量、工蚁诱集量的消长动态进行了监测,并且根据2017、2018年观察到的共21次婚飞,结合气象资料分析其规律。结论如下:西昌市安宁河谷的气候总体适宜红火蚁生存;3月至5月中旬为防治关键时期;3月至12月可选择合适的天气防控。工蚁诱集量与一定范围内的旬平均气温、月平均气温和旬降水量存在显著相关性。可据此选择合适的天气施用毒饵,提高防控效果。Dynamics of the changing numbers of imported red fire ant(Solenopsis invicta Buren)nests and worker ants attracted together was monitored from April 29,2017 to February 19,2019 in Xichang,and their nuptial flight was observed for 21 times in 2017 and 2018.Then the regularity of the dynamics of S.invicta population was analyzed in combination with the meteorological information.The results indicated that the climate in Anning Valley,Xichang was generally suitable for the survival of imported red fire ant,and March to mid-May was the key period for control.In addition,control of S.invicta is feasible during March to December while weather is appropriate.There is a significant correlation between the number of worker ants attracted together and the ten-day average temperature within a certain range,the monthly average temperature and the ten-day precipitation within a certain range.Based on these,we can choose suitable weather and use poison bait to improve the control effect.
