摘要
目的 研究印鼠客蚤实验室种群的性比和羽化规律，为蚤类生长发育、生态习性、传病机制、生理毒理和防制药剂开发等的研究奠定基础。方法 用人工饲料和小白鼠分别喂饲印鼠客蚤的幼虫和成蚤，在饲养过程中记录幼虫的化蛹和羽化过程，并鉴别羽化成蚤的性别。结果 印鼠客蚤的平均羽化率为（78．7±7．5）％，羽化成虫的性比雌：雄为1．55：1。羽化的第1～5天、第6～17天和第18～20天雌蚤分别占（96．2±3．5）％、（61．0±6．4）％和（10．0±8．7）％，相互间差异有统计学意义；有（82．3±2．1）％的蚤在第6～17天羽化，此时是羽化高峰期。结论 印鼠客蚤实验种群中雌性个体较雄性个体多，蛹的羽化率较高。
Objective To provide basic information for the study of oriental rat flea＇s （Xenopsylla cheopis ） development, ecological habit, mechanism of disease transmission, physiology and toxicology, and insecticide exploitation et al., the sex ratio and adult eclosion activity of X. cheopis were studied in laboratory population. Methods The larva and adult rat flea were reared with artificial diet and white mouse respectively. The process of larva pupation and adult emergence were recorded, and the sex ratio was calculated during the flea development. Results The average eclosion ratio was （78.7 ± 7.5 ） %, and the sex ratio was ♀：♂=1.55 ： 1. Female adult was account for （96.2 ± 3.5 ） % , （61.0 ± 6.4 ） % and （ 10.0 ± 8.7） % for the 1st-5th, 6th-17th and 18th 20th eclosion days respectively. The adult emergence peak was from the 6th to 17th days, and there were （82.3 ± 2.1 ） % pupae turned in adults at this time. Conclusion The result shows X. cheopis has a relative higher eclosion ratio. In laboratory population of X. cheopis the female adult is more than the male.
