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.COPYRIGHT: (C)2016,JPO&INPIT【課題】本発明の目的は、より簡便に益虫を他の害虫から分別して採集可能とした益虫分別採集装置及び益虫分別採集方法を提供することにある。【解決手段】害虫(Y)に対する益虫(X)を、該益虫(X)と体長の異なる他の虫(Z)と分別して採集するための益虫分別採集装置(1)であって、中空状の本体部(4)と、本体部(4)の一方の開口端(6)と連通され、益虫(X)及び他の虫(Z)を投入するために開口された開口投入部(8)と、本体部(4)内において、開口投入部(8)と反対側の位置に設けられた、益虫(X)に対する誘引性を示す波長の光を発することが可能な光源(10)と、本体部(4)内で開口投入部(8)と光源(10)との間に設けられ、本体部(4)内を、開口投入部(8)側の投入側領域と、光源(10)側の光源側領域とに区画すると共に、益虫(X)又は他の虫(Z)のいずれか一方を通過させ、他方を通過させない大きさに目を形成したメッシュ部(12)とを備えることを特徴とする。【選択図】図1
