Abstract

Background: In this study we examine the feeding efficiency of copepods locally found in Guatemala on first instar Aedes aegypti larvae. Copepods are a potential tool for Aedes vector control that has shown promising results in the laboratory and in community-based field trials.

Methods: Four different copepod species from different habitat types were included in the laboratory assays of this study.

Results: All four tested copepod species decreased the number of the first instar Aedes larvae that were inserted into the glass vessels compared with controls. However, average predation rates between the tested species were highly different, with Thermocyclops crassus and Mesocyclops longisetus achieving the highest, with 31.0% (standard deviation [SD] 18.9) and 28. 9% (SD 11.2), respectively.

Conclusions: The copepod species with identified high predation rates are potential candidates for planned and other future field trials for community-based Aedes vector control with copepods in the region.

评估危地马拉本地桡足类控制伊蚊病媒的潜力。

背景：在这项研究中，我们考察了危地马拉当地发现的桡足类对埃及伊蚊初孵幼虫的摄食效率。桡足类是一种潜在的伊蚊病媒控制工具，在实验室和社区实地试验中均显示出良好的效果：本研究的实验室试验包括来自不同生境类型的四种不同桡足类：结果：与对照组相比，所有四种受测桡足类动物都减少了伊蚊幼虫插入玻璃容器的初生数量。然而，受试物种之间的平均捕食率差异很大，其中以热环桡足类和中环桡足类的捕食率最高，分别为 31.0%（标准偏差 [SD] 18.9）和 28.9%（标准偏差 11.2）。结论：已确定的高捕食率桡足类物种是该地区计划中和未来其他实地试验中利用桡足类进行社区伊蚊病媒控制的潜在候选物种。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
