Biological research auxiliary device for catching insects and screening size of wings

Abstract

The invention relates to the technical field of biology, and discloses a biological research auxiliary device for catching insects and screening the size of wings. The biological research auxiliary device comprises a collecting box, wherein the lower part of a curved sliding groove comprises a high sliding rail and a low sliding rail; a first magnet is arranged in a fixing groove; a first negativeplate is arranged at the middle part of the collecting box; a second negative plate and a corresponding positive pole electroplate are arranged on the left side of the lower part of the collecting box; and a plurality of classification bottles are arranged at the lower end of the collecting box. According to the biological research auxiliary device disclosed by the invention, insects passing through the first negative plate are applied with negative charges; when the insects are moved between the second negative plate and the positive pole electroplate, the sliding speed of the insects is reduced caused by the adsorption force of the positive pole electroplate; and the heights of the high sliding rail and the low sliding rail at the lower part are different, the insects at a lower speed slide off to a classification bottle on the leftmost side, and the insects at a higher speed slide off to a classification bottle on the rightmost side, so that through the adoption of the structure disclosed by the invention, the problem that a conventional insect catching and screening device cannot screen insect wings of different sizes is solved.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a biological research auxiliary device used for catching insects and screening the size of wings. Background technique [0002] Insects are also called arthropods. They belong to the arthropods among the invertebrates and are the most numerous animal groups on the earth. Until the beginning of the 21st century, there were more than 1 million species of insects known to humans, but there are still many species yet to be discovered. . Insects play an important role in the biosphere. Entomophilous flowers need the help of insects to spread pollen. Most insects can be used as specimens, which are good biological resources that humans can use. [0003] People need to capture and classify insects in the process of studying their body postures. At present, there are many devices for catching and classifying insects. Centrifugal force), etc., cannot screen insects with different ...
