Opening type insect wavelength selector

The utility model relates to an insect phototaxis study device, in particular to an opening type insect wavelength selector. The problem that currently, an insect phototaxis study device cannot be used in a natural environment, and a plurality of light sources can cause interference easily is solved. The opening type insect wavelength selector comprises a base. At least three partitioning plates which are arranged in a radial mode are arranged in the vertical direction on the base. An opening space is formed between adjacent partitioning plates and the base and is used as an insect inducing zone. Power grids and light sources with different wavelengths are arranged in the insect inducing zones. The opening type insect wavelength selector has the advantages that the selector can be directly placed outdoors and be used for a greenhouse, and manual insect catching putting is of no need; light wavelengths between the insect inducing zones does not interfere with each other, and study results are accurate and reliable; the structure is simple, and manufacturing cost is lowered; and the opening type insect wavelength selector can be directly used as a lamp for inducing, capturing and killing insects.
