The utility model discloses an electric mosquito-suction device, which is used for collecting medical vector organisms. The device comprises a power supply module, a motor, a fan, a shell, a container, a filter net and an illumination device, wherein the motor is electrically connected to the power supply module to obtain power supply; the fan is arranged on a rotating shaft of the motor and is rotated under the driving of the motor, and the wind direction of the fan faces the motor; the shell is used for accommodating the power supply module, the motor and the fan; the container at least comprises an air suction inlet and an air outlet, and the air outlet of the container is connected to the air suction inlet of the fan; the filter net covers the air outlet end of the container; and the illumination device is arranged on the surface of the shell or the surface of the container. Due to the arrangement of the illumination device in the electric mosquito-suction device, the illumination for a night collection work field is convenient to realize, vector organisms, such as mosquitoes, are simultaneously attracted to the collection work field by utilizing the phototaxis of the vector organisms, so that the efficiency of collection work is effectively improved.
