方形黄鼠蚤松江亚种的实验养殖

Laboratory breeding of the ground squirrel flea

蚤类养殖技术始于19世纪初,以后 Boxton(1948)等诸位学者对蚤类的生物学特性进行了多方面的研究,Smith-Eddy(1954)、Vaughan-Coombs(1979)等介绍了养蚤方法。在国内关于蚤类养殖的报道甚少,王敦清(1957)、肖伯林(1985)曾报告普通实验室的养蚤方法。

From April 1982 to August 1985,we explored the laboratory breeding tech-niques of ground squirrel flea Citellophilus tesquorum sungaris Roths,Bothmixed and separate rearing methods of adults and immature were used,the latterwas much better.46 generations were breeded in this period.A generationrequires 24 days or so.The egg stage is 2-3 days.The immature stage is 6-8days.The pupae stage is 8-14 days。Adults begin egg-lay on the second dayafter sucking-blood.We have explored the regular as standard breeding tecnhniquesof C.t.sungaris.Quality determining results of general breeding and regularbreeding are as the following separately:1,The fecundity are 0.77±0.14 adults/♀.day;1.16±0.20 adults/♀.day.2,The average longevity of un-sucking blood adults are 14.3±1.0 days;13.1±1.8 days.3,The average weight of new emergence adults are ♀ 0.42±0.03mg,0.46±0.04mg;♂0.33±0.03mg,0.35±0.03mg。The fluctuations of quality determining results among generations wereslight,therefore it showed that the breeding quality was stable and the breedingtechniques were reliable and practical.Regular fleas used in the experiment maybe provided under a well-conceived plan breeding.A good laboratory populationfor standard breeding of C.t.sungaris has been established.
