【摘要】：目的了解云南省疟疾疫情不稳定地区重要传疟媒介按蚊生态习性的变化。方法在景洪市、元江、绥江和龙陵县4个疟疾不稳定区,采用诱蚊灯人(畜)房通宵捕获蚊虫,通宵人工诱捕观察蚊虫夜间活动节律,应用多重PCR方法检测蚊虫胃血血源。结果 4个调查点共捕获18种44 635只按蚊,其中中华按蚊26 468只,微小按蚊2428只,雷氏按蚊100只,昆明按蚊1620只,其他按蚊14 019只,分别占所获按蚊总数的59.30%、5.44%、0.22%、3.63%和31.41%。景洪市微小按蚊夜间活动高峰在23:00-00:00;景洪市和元江县的中华按蚊夜间活动高峰为20:00-21:00;绥江县的中华按蚊夜间活动高峰为02:00-03:00;昆明按蚊夜间活动高峰主要在22:00之前;中华按蚊、微小按蚊和昆明按蚊日预期寿命较高,均在0.90~1.00之间;中华按蚊人血指数为0.30,微小按蚊为0.50,昆明按蚊为0.30。结论微小按蚊、中华按蚊和昆明按蚊生态习性发生了变化,是否引起当地疟疾流行特征发生改变,有待于进一步调查。
[Abstract]:Objective to investigate the changes of ecological habits of important malaria vectors Anopheles mosquitoes in the unstable areas of malaria epidemic situation in Yunnan Province. Methods the methods are in 4 unstable areas of malaria in Jinghong City, Yuanjiang City, Suijiang County and Longling County. Mosquitoes were captured overnight in human (livestock) house and observed the rhythm of mosquito activity at night by artificial trapping. Results A total of 44 635 Anopheles species of 18 species were captured in 4 sites, 26 468 of them were Anopheles sinensis and 2 428 were Anopheles minimus (Anopheles minimus). There were 100 Anopheles Lei's, 1620 Anopheles Kunming and 14 019 other Anopheles, which accounted for 59.305.440.22% of the total number of Anopheles. 3.63% and 31.41. The peak of nocturnal activity of Anopheles minimus in Jinghong City was 2300-00: 00; The peak of nocturnal activity of Anopheles sinensis in Jinghong City and Yuanjiang County was 20: 00-21: 00; The peak of nocturnal activity of Anopheles sinensis in Suijiang County was 02: 00-03: 00; The peak of nocturnal activity of Anopheles repens in Kunming was before 22:00. The life expectancy of Anopheles sinensis, Anopheles minimus and Anopheles Kunming was higher than that of Anopheles sinensis. The human blood index of Anopheles sinensis was 0.30, Anopheles minimus 0.50, Anopheles Kunming 0.30.Conclusion the ecological habits of Anopheles minimus, Anopheles sinensis and Anopheles Kunming have changed. Whether or not the endemic characteristics of malaria in the region have changed remains to be further investigated.
