摘　　要：为明确红火蚁蚁群结构及发生动态,2016年采用计数法和称重法对昆明宜良县红火蚁的蚁群结构及发生动态进行调查。结果表明,2016年蚁巢地上部分,职能蚁和生殖蚁的数量分别为98.15%、1.85%,职能蚁以工蚁和兵蚁成虫的数量最多为83.38%,生殖蚁以卵、幼虫和蛹的数量最多为52.15%。2016年红火蚁发生高峰期在6—9月,8月数量最多,以职能蚁为主;生殖蚁发生高峰期在6—8月,成虫发生高峰期在6月,卵、幼虫和蛹发生高峰期在8月,因此红火蚁防治的关键时期在5—9月。2016—2017年冬春季红火蚁蚁群中职能蚁数量最大为99.34%,生殖蚁数量为0.66%;蚁巢地下部分红火蚁的数量高于地上部分的数量,地下部分红火蚁数量占59.19%,地上红火蚁数量占40.81%。研究结果可为当地红火蚁防控技术提供依据。In order to clarify the community structure and dynamics of Solenopsis invicta,the community structure and occurrence dynamics of S.invicta in Yiliang County of Kunming City were investigated by counting method and weighing method in 2016.The results showed that the sterile ants and sexual ants of the above-ground parts of nests accounted for 98.15%and 1.85%respectively,in 2016.Among the sterile ants,the number of adult worker ants and soldier ants was the largest,accounting for 83.38%.In the sexual ants’group,the number of eggs,larvae and pupae was the largest,accounting for 52.15%.In 2016,the peak duration of S.invicta’s dynamics was from June to September,with the largest number in August,mainly on sterile ants.The peak period of sexual ants’dynamics was from June to August;for adults,the peak was in June;and the peak period of eggs,larvae and pupae occurred in August.Therefore,the key period for S.invicta control is from May to September.In the winter and spring of 2016-2017,the proportion of maximum number of sterile ants was 99.34%,and that of sexual ants was 0.66%.The number of S.invicta in the underground part of the nest was higher than that in the above-ground part.The number of S.invicta in the underground part accounted for 59.19%,and that in the above-ground part accounted for 40.81%.It provides a basis for the local control technology of S.invicta.
