Method and device for efficiently separating beneficial and harmful insects

Abstract

The invention discloses a device for efficiently separating beneficial and harmful insects. The device comprises an insect collecting box, a device base and an internal box, wherein the top of the insect collecting box is provided with a funnel-shaped insect inlet, the wall of the insect collecting box is encircled by a netlike object, and the wall of the internal box is also encircled by a netlike object; the internal box is fixed on the device base in the center of the insect collecting box; and the bottom of the insect collecting box is connected with the upper part of the device base, and a plurality of natural enemy escape holes are formed at the connected position. According to the device, the aims of killing pests and separating beneficial insects are fulfilled by the way that the pests are eaten by natural enemies of the pests, so that the survival rate of the beneficial insects is greatly improved; and eggs laid by lepidoptera insects provide hosts for the propagation of trichogramma, so that the cost of indoor bee propagation is reduced to a great degree. The natural enemy number of the pests in fields is remarkably increased, so that the number of the pests in the fields is effectively controlled, and the use of chemical agents is reduced and even eliminated; and the device is an indispensable professional insect attracting facility for the development of ecological agriculture.
