摘要

PROBLEM TO BE SOLVED: To provide a device for collecting beneficial insects in a discriminating manner and a method for collecting beneficial insects in a discriminating manner capable of easily collecting beneficial insects while discriminating beneficial insects from other pests.SOLUTION: A device for collecting beneficial insects in a discriminating manner (1) for collecting beneficial insects (X) for pests (Y) by discriminating the beneficial insects (X) from other insects (Z) with different body length includes: a hollow body part (4); an open input part (8) communicated with one open end (6) of the body part (4) which is open for inputting the beneficial insects (X) and other insects (Z); a light source (10) provided at a position opposite to the open input part (8) in the body part (4) for emitting the light of a wavelength that shows attractiveness to the beneficial insects (X); and a mesh part (12) provided between the open input part (8) and the light source (10) in the body part (4) that partitions the inside of the body part (4) into an input side region on the open input part (8) side and a light source side region on the light source (10) side, in which meshes are formed in the size that allows one of the beneficial insects (X) and the other insects (Z) to pass through the meshes, and does not allow the other to pass through them.
