Insect phototaxis behavior testing device and application thereof

Abstract

The invention relates to an insect phototaxis behavior testing device. The insect phototaxis behavior testing device is composed of a light isolation box, a transparent insect receiving pipe and a light blocking cover plate. The light isolation box is composed of a plurality of single light source chambers, a plurality of dark chambers and a response chamber. The single light source chambers communicate with the response chamber through the dark chambers, and light of the single light source chambers can be transmitted into the response chamber through the dark chambers. The insect receiving pipe is composed of a main pipe and a plurality of branch pipes. The main pipe is a hollow pipe with an upward opening, and one end of each branch pipe communicates with the main pipe. The main pipe and the branch pipes of the insect receiving pipe are embedded into the response chamber and the dark chambers of the light isolation box respectively, and the other ends of the branch pipes communicatewith the single light source chambers. The light blocking cover plate is detachably fixed to the upper portions of the dark chambers and the upper portion of the response chamber. The insect phototaxis behavior testing device is simple in structure and convenient to operate, the taxis behavior response of insects on light sources with different wavelengths can be studied simultaneously, a contrast test is carried out, the optimal sensitive wavelength of the insects can be screened conveniently, the phototaxis response test of the insects on the multiple light sources can be carried out conveniently, and insect biology study is facilitated.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to an insect phototaxis behavior testing device and its application. Background technique [0002] Pest control is an important part of agricultural production. Pest control usually includes chemical control, agricultural control, biological control and physical control. Among them, the behavioral characteristics of insects, such as phototaxis, are used in physical control to control pests, which can greatly reduce the use of chemical pesticides. The response of insects to light and move toward the light source is called phototaxis. It is one of the main behavioral characteristics of insects. It plays an important role in various behaviors of insects, affecting insects' feeding, mating, reproduction, etc. wait. Most insects have phototaxis, but different insects respond differently to light waves. By studying the responses of insects to light of different wavelengths and s...

AI Technical Summary

Problems solved by technology

The research on phototaxis of insects at home and abroad has a long history and has good practical application value. However, the phototaxis behavior testing devices used in the research are relatively simple, and only one wavelength of light can be measured at a time. The reaction of the experiment is time-consuming, and there are many interference factors, which affect the accuracy of the experiment.
