Bidirectional selection device for behavior determination of thrip pests

The utility model discloses a two-way selection device for behavior determination of thrip pests. The two-way selection device comprises a device frame structure and application methods of different behavioral experiment researches. The device is used for observing and researching taxis of visual organs of thrips to different light qualities and light intensities, behavioral experiments of the thrips in different light environments and avoidance behavioral experiments of olfactory organs to volatile substances; the release box (1), the first processing signal box (6) and the second processing signal box (7) in the device are formed by splicing full-spectrum light-transmitting quartz glass plates with the thickness being 2 mm, the device has the advantages of being multifunctional, simple, economical, applicable and the like, the efficiency and simplicity of behavioral research on thrip pests are improved, and the device is suitable for popularization and application. Effective observation and fundamental rese
