摘　　要：目的了解宁夏某训练场蚊虫种群构成、密度情况,为有效控制蚊虫肆虐及蚊媒疾病传播提供科学依据。方法 8月在宁夏某训练场选取具有代表性的不同生境的3个地点作为调查点,并采用二氧化碳诱蚊灯诱捕法进行蚊虫采集。结果共捕捉成蚊2 285只,分为2属5种,其中背点伊蚊占74. 49%,淡色库蚊占21. 88%,里海伊蚊占2. 28%,黄背伊蚊占0. 70%,凶小库蚊占0. 65%。背点伊蚊为该训练场区周边优势蚊种。在捕获的成蚊中,饱血蚊占0. 93%,背点伊蚊与淡色库蚊吸血率比较无统计学意义(X^2=0. 146,P=0. 723> 0. 05)。背点伊蚊在营区的吸血率与在水塘的相比较具有统计学意义(X^2=26. 37,P=2. 81×10-7)。蚊虫活动高峰期出现在20:00—22:00和04:00—06:00这两个时段,捕捉数量占总数的46. 89%。结论初步摸清了宁夏某训练场蚊虫种群构成、密度及活动规律等情况,为后续蚊虫防控提供了科学参考。Objective To find out the mosquito species and density in at raining ground in Ningxia,and provide scientific basis for the effective control of mosquito and mosquito-borne disease.Methods Selecting three investigation points with differently characteristic ecosystem and taking CO2 trapping lamp method to collect mosquitoes in August.Results A total of 2 285 mosquitoes were trapped with CO2 trapping lamp method,classified as 2 genus and 5 species.74.49%of the total captured mosquitoes were Aedes dorsalis,21.88%Culex pipiens pallens,2.28%Aedes caspius,0.70%Aedes flavidorsalis and 0.65%Culex modestus.Aedes dorsalis was the dominant species.Blood-sucking mosquitoes accounted for 0.93%.The difference of blood-feeding rates between Aedes dorsalis and Culex pipiens pallens was little different(Х^2=0.146,P=0.723>0.05),while the blood sucking rates of Aedes dorsal in camp and in pool was significantly different(Х^2=26.37,Ρ=2.81×10^-7).Time period of 20:00-22:00 and 04:00-06:00 were the peak periods of mosquito activity,46.89%of the total of mosquitoes were collected in the time periods.Conclusion The species composition,density and activities of mosquitoes in a training ground in Ningxia were attained,providing a scientific suggestion for the further prevention and control of mosquito.
