The invention discloses a parallel type aphis feeding and transferring device and a method for transferring and collecting aphides. The device comprises two rectangular box bodies which are arranged front and back in an adjacent mode and have the same structure. A top plate of each rectangular box body is a transparent face plate. Gauzes are arranged on four side plates of each rectangular box body. Two adjacent side plates of the two rectangular box bodies are sliding side plates which are in sliding connection with the box bodies. Sealing devices are arranged on the contact faces of the two rectangular box bodies and are connected with the two rectangular box bodies through clamping devices. A side plate gauze, except for side plate gauzes on adjacent sliding side plates, on each of the two rectangular box body is connected with one end of a communication device, and the other end of the communication device is connected with an aphis collecting device. An insect inducing collecting lamp is arranged on one side of the aphis collecting device. Aphides can be collected easily and conveniently during feeding, aphis collecting efficiency is improved, damage to aphis bodies is avoided, during living body plant replacing, aphis escaping can be effectively avoided, and ecological safety is guaranteed.
