目的查清东南沿海某军事演习区域蚊虫生态习性及危害状况,为蚊虫防治提供依据。方法采用CO2诱蚊灯诱捕和网捕法定期采集蚊虫,并分类鉴定统计,调查蚊虫种群组成及昼夜活动情况,观察蚊虫刺叮指数和了解驻地蚊虫叮咬反应及近5年来蚊媒传染病的发病情况。结果该军事演习区域蚊类共6属12种,优势种依次为三带喙库蚊(35.04%)、致倦库蚊(25.91%)、中华按蚊(18.54%)、骚扰阿蚊(10.17%)和白纹伊蚊(7.11%);蚊虫昼夜均有活动,活动高峰分别为日出前1h(05:00)和日落后1～2h(19:00-20:00);蚊虫的刺叮以日出前、日落后1h其活动高峰时为盛,蚊虫刺叮指数在日落后1h最高达14次/15min;蚊虫对人的主要危害是吸血刺叮骚扰,轻者引起虫咬性皮炎,重者出现全身过敏反应,而新进入人群66.74%症状较重,96.33%出现烦躁不安、易激怒等心理反应;在传播疾病方面驻地近5年无疟疾报告,但流行性乙型脑炎和登革热常有散在发生,对进驻部队有潜在威胁。结论部队进驻该区域军事演习或训练,蚊虫防治必须要采取以生态学为基础的综合防治策略。
Objective To find out the ecological habits and harm status of mosquitoes in a military exercise area along the southeast coast and provide the basis for the prevention and control of mosquitoes. Methods CO2 mosquito trap and net catching were used to collect mosquitoes regularly. The mosquito species composition and diurnal activity were investigated. The index of mosquito bites and mosquito bites were observed. The incidence of mosquito-borne infectious diseases in the past five years was also observed. Happening. Results There were 12 species of mosquitoes belonging to 6 genera in the military exercise area. The dominant species were Culex tritaeniorhynchus (35.04%), Culex pipiens quinquefasciatus (25.91%), Anopheles sinensis (18.54%), ) And Aedes albopictus (7.11%). The mosquitoes had activities both day and night with peak activity at 1h (05:00) before sunrise and 1 ~ 2h after sunset (19: 00-20: 00) Before sunrise, 1h after sunset its activity peak Sheng, mosquito bite index at 1h after sunset up to 14 times / 15min; mosquito on people’s main hazards are blood stab bites harassment, the light of insect bites dermatitis, Severe systemic allergic reaction, and the newly entered the population 66.74% of the symptoms heavier, 96.33% appear irritability, irritability and other psychological reactions; in the transmission of disease resident in the past 5 years without malaria report, but Japanese encephalitis and dengue fever Often scattered in the presence of potential threats to the presence of troops. Conclusion As the troops stationed in the region for military exercises or training, the prevention and control of mosquitoes must adopt a comprehensive ecology-based prevention and control strategy.
