Abstract

Ctenocephalides felis is an ectoparasitic flea species commonly found on dogs and cats. The current study verified the in vitro virulence of conidia of the entomopathogenic fungus Beauveria bassiana produced under different color LED light (red, blue, purple, green, yellow, and white) to adults of C. felis. The fungal isolates were cultivated on malt extract agar (MEA). Bioassay treatments used aerial conidia in test tubes. Adult fleas were obtained from a house cat in Chiang Mai province, Thailand. The experiments were composed of one control and eleven treatment groups. All of the treatments with B. bassiana conidia caused adult mortality after an exposure of 12 h. Among the conditions used in this study, B. bassiana cultured under red LED and fluorescent light were the most effective in causing mortality (100 %) in adult fleas after 36 h. The experimental results indicate that these aerial conidia of B. bassiana have promising potential for use in control of C. felis adult stages.

LED光下球孢白僵菌气生分生孢子对猫蚤的毒力

猫头蚤是一种常见于狗和猫的外寄生蚤。本研究验证了在不同颜色LED光(红、蓝、紫、绿、黄、白)下产生的球孢白僵菌(Beauveria bassiana)分生孢子对猫毛线虫成虫的体外毒力。分离真菌在麦芽提取物琼脂(MEA)上培养。试管中气生分生孢子的生物测定处理。从泰国清迈省一只家猫身上获得成蚤。实验分为1个对照组和11个治疗组。所有处理均在暴露12 h后导致成虫死亡，其中在红色LED和荧光条件下培养的球孢白僵菌在暴露36 h后的成虫死亡率最高(100%)。实验结果表明，球孢白僵菌气生孢子在控制绒蚤成虫阶段具有良好的应用前景。

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.
