目的比较诱蚊灯法和人工小时法在现场捕获蚊虫的效果,为制定科学合理的病媒生物监测方案或蚊虫调查提供依据。方法选择茂名市城区居民、公园、医院、城郊结合部农户及牲畜棚5个点,同时使用2种方法捕蚊,对捕获的蚊虫进行分类鉴定并进行统计分析。结果诱蚊灯法在5种环境共捕获成蚊3属5种14 509只,致倦库蚊、三带喙库蚊和白纹伊蚊分别占捕获蚊总数的97.98%、0.99%和0.88%,中华按蚊占0.12%,其他蚊种占0.02%。人工小时法在4种环境共捕获成蚊4属7种6 583只,致卷库蚊、白纹伊蚊和三带喙库蚊分别占90.11%、6.09%和3.11%,中华按蚊占0.30%,其他占0.38%。不同环境类型蚊种构成比不尽相同,以牲畜棚的蚊密度最高。2种方法监测结果显示成蚊密度季节消长趋势基本一致,3月份开始升高,5~6月达到高峰,7~8月逐渐下降,9~10月有所回升,11月蚊虫进入越冬状态。结论人工小时法和诱蚊灯法均能用于蚊虫调查和监测,但各有长处及短处,人工小时法对采集靶标蚊虫、嗜吸人血的蚊虫和发现更多蚊种有较大优势;诱蚊灯法则更适合于蚊媒哨点长期监测,既节省劳力,又避免人为的主观性影响及人蚊接触感染相关传染病。
Objective To compare the effect of mosquito lamp and artificial hour method to capture mosquitoes in the field and provide the basis for establishing a scientific and rational vector bio-monitoring program or mosquito survey. Methods Five sites of residents, parks, hospitals, rural households and livestock sheds in urban areas of Maoming were selected. Two methods were used to catch mosquitoes, and the captured mosquitoes were identified and analyzed statistically. Results The larvae of Culex pipiens pallens, Culex tritaeniorhynchus and Aedes albopictus accounted for 97.98%, 0.99% and 0.88% of the total number of captured mosquitoes, respectively, in 5 environments, , Anopheles sinensis accounted for 0.12%, other mosquito species accounted for 0.02%. The artificial hour method captured 6 583 mosquitoes, 4 genera and 7 species in four environments, and the numbers of Culex pipiens, Aedes albopictus and Culex tritaeniorhynchus were 90.11%, 6.09% and 3.11% respectively, while Anopheles sinensis accounted for 0.30 %, Others account for 0.38%. Different types of mosquito composition of different environmental types, to livestock shed highest mosquito density. The monitoring results showed that the density of adult mosquitoes had basically the same trend of increasing and decreasing in the season, beginning to increase in March, reaching the peak in May to June, decreasing gradually from July to August and recovering from September to October. The mosquitoes entered the wintering state in November. Conclusion Artificial hours and mosquito lamp method can be used for mosquito surveys and monitoring, but each has strengths and weaknesses, artificial hours method for the collection of target mosquitoes, addicted to absorb blood of mosquitoes and more mosquito species have greater advantages; The mosquito lamp rule is more suitable for the long-term monitoring of mosquito melalese sentinels, which not only saves labor, but also avoids the subjective influence of human and mosquito contact infection-related infectious diseases.
