目的在河北省承德地区采集蚊虫,探讨海拔高度、生境类型和成幼虫调查方法3个因素对蚊种调查的影响,为高效开展蚊媒调查,预防和控制蚊媒传染病提供参考。方法于2015年7-8月在承德地区不同海拔高度选取3类生境开展蚊种调查,成蚊采集使用诱蚊灯法和栖息蚊虫捕捉法,幼虫采集使用吸管法和勺捕法,采用多分类logistic回归进行多因素分析。结果本次调查蚊种构成为中华按蚊(45.12%)、淡色库蚊(27.44%)、骚扰阿蚊(11.03%)、朝鲜伊蚊(6.90%)、迷走库蚊(6.23%)、刺扰伊蚊(2.44%)、米赛按蚊(0.42%)和仁川伊蚊(0.42%),其中米赛按蚊为河北省的新纪录。海拔高度、生境类型和成幼虫调查方法是蚊种调查的影响因素。以淡色库蚊为参考类别,中高海拔更易出现迷走库蚊、中华按蚊、朝鲜伊蚊和刺扰伊蚊,中低海拔更易出现骚扰阿蚊;种植养殖区更易出现中华按蚊、骚扰阿蚊和朝鲜伊蚊,农村居民区更易出现中华按蚊,不易出现朝鲜伊蚊;采用幼虫调查方法更易捕获迷走库蚊、骚扰阿蚊、仁川伊蚊和朝鲜伊蚊。结论承德地区应特别关注中华按蚊在中高海拔地区、种植养殖区和农村居民区生境的种群和密度消长,对该蚊种易出现区域应采取适当的灭蚊措施,从而预防和控制当地疟疾等蚊媒传染病的发生。
Objective To collect mosquitoes in Chengde, Hebei Province, and to investigate the influence of altitude, habitat type and larva survey methods on mosquito species survey in order to provide reference for high mosquito vector investigation, prevention and control of mosquito-borne infectious diseases. Methods Three types of habitats were selected from different altitudes in Chengde Prefecture from July to August 2015 to carry out mosquito surveys. Mosquitoes were collected by mosquito lamp and perched mosquito, larvae were collected by straw and scoop method, Logistic regression was multivariate analysis. Results The mosquito species in this survey were 45.12%, Culex pipiens pallens (27.44%), Aries mosquito (11.03%), Aedes albopictus (6.90%) and Culex pipiens pallens (6.23%), Aedes albopictus (2.44%), Anopheles stephensi (0.42%) and Ae. Albopictus (0.42%), of which Anopheles stephensi was the new record in Hebei province. Elevation, habitat types and larvae survey methods are the influencing factors of mosquito species survey. Culex pipiens pallens were taken as a reference category, and Culex pipiens pallens, Anopheles sinensis, Aedes albopictus and Aedes albopictus were more likely to appear in the middle and high altitude, and mosquitoes were more likely to be harassed in the middle and low altitudes. And Aedes albopictus, the An. Sinensis is more likely to appear in rural residential areas, and the Aedes albopictus is less likely to appear. Larvae survey method is more likely to catch Culex pipiens and Hara mosquito, Ae. Albopictus and Ae. Albopictus. Conclusions Special attention should be paid to the population growth and density growth of Anopheles sinensis in habitats at medium altitude and high altitude, planting and breeding areas and rural residential areas, and appropriate mosquito control measures should be taken in areas prone to this mosquito so as to prevent and control local malaria, etc. Mosquito-borne infectious disease.
