摘要
目的观察簇鬃客蚤在实验室饲养条件下的生活史。方法在温度(26±0.5)℃、相对湿度(70±5)%条件下,以子午沙鼠为供血动物,采用常规饲养和平皿中培育相结合的方法进行观察。结果簇鬃客蚤属全变态昆虫,其全部生活史分为卵、幼虫、蛹(茧)和成虫4个阶段;簇鬃客蚤(♂)发育各历期(卵-幼虫、幼虫-蛹、蛹-成虫及卵-成虫)的发育天数分别为(5.65±0.49)、(10.78±0.67)、(7.52±0.95)和(23.96±1.49)d,簇鬃客蚤(♀)发育各历期的发育天数分别为(5.49±0.51)、(10.20±0.78)、(4.90±1.04)和(20.59±1.14)d;簇鬃客蚤的孵化率(卵-幼虫)、化蛹率(幼虫-蛹)、羽化率(蛹-成虫)及成长率(卵-成虫)分别为91.0%、85.7%、82.1%和64.0%;簇鬃客蚤羽化后的雌雄性比为1.8:1;簇鬃客蚤饥饿状态下的寿命为(4.17±1.11)d(♂)和(5.31±1.69)d(♀),簇鬃客蚤供血状态下的寿命为(13.56±2.56)d(♂)和(20.50±8.31)d(♀);簇鬃客蚤每组(以15雄10雌为一组)每日平均产卵数为23.46粒,一生平均产卵数为(624.00±5.76)粒,每日平均产卵数(n)与产卵时间(d)之间的非线性回归方程为y=e[4.548-0.140(x-2)](x≥3)。结论簇鬃客蚤生活周期短、繁殖力强,有利于传播和促进动物鼠疫流行。
Objective To observe the life cycle of Xenopsylla skrjabini under laboratory conditions.Methods Meriones meridianus was served as blood-supplying animal under the conditions of（26±0.5）℃ and 70%±5% RH with routine breeding and plate culture.Results The entire life cycle of holometabolic X.skrjabini could be divided into 4 stages（egg,larva,pupa/cocoon and adult）.The development periods（egg-larva,larva-pupa,pupa-adult and egg-adult） were 5.65±0.49 d,10.78±0.67 d,7.52±0.95 d,and 23.96±1.49 d for the male,respectively;5.49±0.51 d,10.20±0.78 d,4.90±1.04 d and 20.59±1.14 d for the female,respectively.The hatching rate（egg-larva）,pupation rate（larva-pupa）,emergence rate（pupa-adult） and growth rate were 91.0%,85.7%,82.1% and 64.0%,respectively.The sex ratio after emergence was 1.8：1.The longevities were 4.17±1.11 d for the male and 5.31±1.69 d for the female under starvation,13.56±2.56 d for the male and 20.50±8.31 d for the female under supplying blood.The average number of laying eggs per day（15 males and 10 females as a unit） was 23.46,and the average lifetime number was 624.00±5.76.The non-linear regression equation between the average daily number of laying eggs（n） and oviposition time（d） was y=e[4.548-0.140（x-2）]（x≥3）.Conclusion The short life cycle and high productivity of X.skrjabini were in the favor of transmission and prevalence of animal plague.
