Field multifunctional insect detaining and collecting test tube device

Abstract

The invention discloses a field multifunctional insect detaining and collecting test tube device. One end of an insect detaining tube is open, the other end of the insect detaining tube and the top end of an insect storage tube are in threaded connection, and the bottom end of the insect storage tube, a ventilating screen and a generator are in threaded connection. An opening and closing baffle is arranged in the insect detaining tube, the ventilating screen is arranged at the joint of the insect storage tube and the generator, a ventilating screen hole plate is arranged on the ventilating screen, small screen holes are formed in the plate, and cotton is placed in the generator. The device has the advantages that all the parts are convenient to detach and replace; re-escape of insects is effectively avoided; drop resistance is achieved, and it is avoided that the appearance integrity of small insects is damaged due to the fact that plastic materials generate static; the insects in the tube can be paralyzed through alcohol gas to be in a coma, the active degree of the insects is reduced, limb damage and deficiency caused by space competition fight among the insects are reduced, DNA of insect specimens saved after alcohol fumigation is not prone to degradation, molecular relevant experiments can be carried out, and meanwhile later insect shape classification work is also promoted.

Description

technical field [0001] The invention relates to a field multifunctional insect collection test tube device, which belongs to the technical field of insect collection devices. Background technique [0002] At present, the collection of wild insects provides important research materials for insect classification. During the collection process, the living habits of different insect species can be understood. A collection technology of . At present, there are two main methods of insect collection, namely active collection (net capture method, shock drop method and search method, etc.) [0003] With the continuous development of entomology, exchanges and cooperation with international entomologists are increasing, and the processing methods for collected insects are more refined. According to literature review and daily field collection experience, some deficiencies and defects of current insect collection are simply listed: 1. In the field collection, insects escape again seri...

AI Technical Summary

Problems solved by technology

According to literature review and daily field collection experience, some deficiencies and defects of current insect collection are simply listed: 1. In the field collection, insects escape again seriously; , most of the insects will jump out and escape, which will greatly reduce the collection efficiency; 2. The insect limb structure (such as front and rear wings, front, middle and rear feet, etc.) is seriously damaged, which is not conducive to the development of classification based on morphology; 3. In the wild The post-collection treatment of insects is too simple, which is not conducive to the comprehensive utilization of multiple disciplines and fields; for example, once live insects are poisoned with camphor balls or soaked in alcohol, the former will easily lead to DNA degradation, which is not conducive to carrying out molecular experiments, and the latter's appearance and color will easily fade. It is not conducive to the development of morphological classification

[0004] Nowadays, in order to improve the efficiency of insect collection in the wild, insect extractors (electric and artificial) are mostly used for insect collection, and insects of different sizes are often mixed into plastic insect collection bottles for later use. Although this method greatly improves The number of collected insects is reduced, but because the plastic tube wall is prone to static electricity (causing small insects to adhere to the tube wall) and insect space competition and fighting (insect body "missing arms and legs") is serious, the gain outweighs the gain

[0005] In summary, the current outdoor insect collection tools and methods are still not perfect
