产卵蚊虫监测装置现场应用效果观察

目的通过实验室模拟现场和野外现场实验，观察、评价产卵蚊虫监测装置对产卵蚊虫诱集效果。方法分别在实验室模拟现场和野外现场观察产卵蚊虫诱集器晚间12h诱蚊效果，诱集物为生态水（取自试验现场生境的自然水体）和脱氯自来水。结果实验室模拟现场：当供试蚊虫为雌性时，诱捕率可达到56．5％；当供试蚊虫为雌雄各半时，对雌雄蚊虫的诱捕率分别是40．0％和4．0％。野外现场：在建筑物和人群密集区对蚊虫的诱集效果显著；在草丛及人群稀疏地区对雌性蚊虫的选择性诱集效果显著（t=4．916，P〈0．05）。生态水的引诱效果优于脱氯自来水。结论产卵蚊虫诱集器在实验室模拟现场和野外现场对蚊虫的诱捕作用明显；在野外现场对雌性蚊虫的选择性诱集效果与生境条件、气象因素、蚊种的生态习性和雌性蚊虫的生殖营养节律以及诱集器的放置位置、放置时间等因素有关。

Field application of monitoring devices for spawning mosquitoes

Objective To evaluate alluring effects of monitoring devices on spawning mosquitoes under simulated and field settings. Methods Alluring effects were recorded for 12 h (overnight) in laboratory stimulated and field environments with ecological water (from the field habitats) and dechlorinated tap water as the baits. Results In the stimulated scenario, the trapping rate was 56.5% for female mosquitoes, and in a 50/50 subject group 40.0% and 4.0% for female and male mosquitoes, respectively. In the field, obv...
