The utility model relates to an artificial blood feeding system for adult mosquitoes. The artificial blood feeding system comprises a constant-temperature water bath kettle and feeders, and is characterized in that an inlet and an outlet are formed in the constant-temperature water bath kettle; a plurality of feeders are connected in parallel between the inlet and the outlet through hoses; a main valve is arranged on the hose at the outlet of the constant-temperature water bath kettle; branch valves are respectively arranged at the inlet ends and outlet ends of the feeders of the parallelly connected pipelines; each feeder comprises a mosquito cage; a blood feeder is fixed at the upper end of each mosquito cage; a blood feeding film wraps an opening in the lower end of each blood feeder; the blood feeders have sleeve type structures and comprise inner-layer pipe walls and outer-layer pipe walls; a cavity is formed between each inner-layer pipe wall and each outer-layer pipe wall; a blood inlet is formed in the upper end of each inner-layer pipe wall and is communicated with the opening in the lower end of each blood feeder; and a water inlet and a water outlet are formed in each outer-layer pipe wall and are communicated with the corresponding cavity. The artificial blood feeding system can be used for selectively preserving heat of the blood feeders; and resources can be saved.
