Abstract

The invention discloses application of lotus corniculatus in the aspect of insect ecological regulation and control and an insect regulation and control method of the lotus corniculatus, and belongs to the technical field of pest prevention and control. On the one hand, application of the lotus corniculatus in insect ecological regulation and control is provided, and on the other hand, an insect regulation and control method based on lotus corniculatus is provided, namely, lotus corniculatus is planted in a target area where alfalfa thrips need to be regulated and controlled. The lotus corniculatus can obviously improve the density of orius minutus which is the natural enemy of thrips, a good shelter can be provided for the orius minutus, the thrip density is increased after the alfalfa area revives, and the thrip density can be controlled to not rebound to the high density before initial harvesting by means of the high-density natural enemy orius minutus preserved in the lotus corniculatus shelter, so that the aim of regulating and controlling thrip can be achieved.
