Abstract：Objective To rear Xenopsylla cheopis, and to observe and record its morphological changes and characteristics in various stages of life cycle. MethodsXenopsylla cheopis was reared and bred using wet filter papers combined with petri dishes. Stereomicroscope and microscope imaging system were used to collect, observe, and record the morphological changes and characteristics of X. cheopis in each life-stage. Results The images of morphologic changes of X. cheopis in "egg-larval-pupal-adult" stages were obtained. The period from the eggs being laid to the offspring emerging as adults lasted 26-35 days, including 2-7 days of egg stage, 6-19 days of larval stage, 10-22 days of pupal stage, and 26-60 days of adult stage. The number of eggs laid and the number of larvae hatched followed the circulation mode of "peak-trough" with the time of blood supply. Conclusion There are time-points of morphological changes and developmental stages in the life cycle of X. cheopis, which can provide targets for its precise control.
