Abstract: The observations on the life cycle and ecological characteristics of Monopsyllus anisus show that under the temperature of 21±1℃ and humidity of 80%±5%, the average growth period from eggs to imagoes is about 23.54 days. The duration of eggs is 3.48 days; incubation rate is 80.18%; duration of larvae: lstinstar is 3.20 days, 2nd instar is 4.11 days and 3rd instar is 7.91 days; duration of pupae is 9.34 days; emergence rate is 97.18%. The observations were also carried out on the size of imagoes, weight and quantity of sucking blood; mating, oviposit and incubation; bloodthirsty and blood sucking rate; blood supply concern with oviposit and life-span; the effect of growth metamorphosis on the period of low temperature preserve of eggs and cocoons. The posibility of mating fertilization of the new emergence flea before blood sucking and the phenomenon and the couses of long-term laying fertilization eggs that the ♀ flea is once being mating have been discussed. The knowledge on the biology and ecology of Monopsyllus anisus has been develped and deepened.
