Abstract：Objective To study the blood-sucking and blood-engorging rates of different host-types of cat fleas in laboratory, and provided experimental materials for further study on the transmission of infectious diseases and vectorial capacity of cat fleas. Methods The newly emerged, 30-min and 1 to 4 days old cat fleas which have adapted to lab rat, lab mouse and cat were allowed to feed on their corresponding hosts. The blood-sucking and blood-engorging rates were observed at different time points, and statistical analysis was performed with SAS 9.4 software. Results There was no significant difference in the rate of blood sucking between the rat-and mouse-adapted fleas with ages of 1, 3, and 4 days old. The difference of the rate of blood engorging between 2-4 days old fleas was significant, i. e. χ2=136.206, P<0.001 in the rat-adapted fleas, χ2=219.709, P<0.001 in the mouse-adapted fleas. The blood-sucking and blood-engorging rates of rat-and mouse-adapted fleas all increased with the time of blood-sucking. The order of host preference to three feeding animals was cat > rat=mouse in cat-adapted fleas, rat > cat > mouse in rat-adapted fleas, and mouse=cat > rat in mouse-adapted fleas. Conclusion Different blood-sucking time and different blood-supplying hosts all had an effect on the blood-sucking rate and blood-engorging rate of cat fleas, suggesting that the fleas were highly adaptable and can shift their hot preference and alter their vectorial capacity.
