Abstract

Mosquito surveillance typically uses Centers for Disease Control and Prevention (CDC) mosquito light traps baited with CO2. From January 2013 to March 2015, we sampled seven field sites using three active mosquito-trapping techniques (two different aspirators and a sweep net) and the stationary CO2-baited CDC mosquito light trap to determine mosquito capture efficacy for each technique. Sampling occurred in four suburban backyards and three dog kennel facilities near Gainesville, FL, USA; species collection and relative abundance were measured. A total of 32 species and 70,090 individual mosquitoes were collected, including a new record for Alachua County, Florida, Aedes hendersoni (Cockerell). The dominant (>5% of total capture) mosquito species collected during the study included Aedes atlanticus (Dyar and Knab), Aedes infirmatus (Dyar and Knab), Anopheles crucians Wiedemann, Culiseta melanura (Coquillett), Culex erraticus (Dyar and Knab), Culex nigripalpus Theobald, and Uranotaenia sapphirina (Osten Sacken). The CDC trap captured the most species (29), followed by large aspirator (28), small aspirator (26), and the sweep net (23). All dominant species were captured with each sampling technique. Excluding Wyeomyia mitchellii (Theobald), all subdominant species (1-5% of total capture) were collected with each sampling technique. Future sampling should consider the utility (e.g., large numbers are readily collected) and limitations (e.g., personnel requirements) of aspirator collections when designing field-based mosquito sampling projects, especially those in residential areas or those focused upon species captured.

摘要

蚊虫监测通常使用美国疾病控制与预防中心(CDC)的二氧化碳诱捕式蚊虫灯诱捕器。2013年1月至2015年3月期间,我们在七个野外地点进行采样,采用了三种主动式蚊虫诱捕技术(两种不同的吸虫器和一个扫网)以及固定的二氧化碳诱捕式CDC蚊虫灯诱捕器,以确定每种技术的蚊虫捕获效果。采样地点位于美国佛罗里达州盖恩斯维尔附近的四个郊区后院和三个犬舍设施;对物种收集情况和相对丰度进行了测量。总共收集到32个物种和70090只个体蚊虫,其中包括佛罗里达州阿拉楚阿县的新记录物种——亨德森伊蚊(科克雷尔)。研究期间收集到的优势(占总捕获量>5%)蚊虫物种包括大西洋伊蚊(戴尔和克纳布)、虚弱伊蚊(戴尔和克纳布)、十字按蚊(维德曼)、黑尾库蚊(科基利特)、迷走库蚊(戴尔和克纳布)、致倦库蚊(西奥博尔德)和蓝宝石蓝带蚊(奥斯坦·萨克恩)。CDC诱捕器捕获的物种最多(29种),其次是大型吸虫器(28种)、小型吸虫器(26种)和扫网(23种)。每种采样技术都捕获到了所有优势物种。除了米切尔怀氏蚊(西奥博尔德),每种采样技术都收集到了所有亚优势物种(占总捕获量的1 - 5%)。在设计基于野外的蚊虫采样项目时,尤其是在居民区或针对捕获物种的项目中,未来采样应考虑吸虫器收集的实用性(例如,易于收集大量样本)和局限性(例如,人员需求)。
