Collection transfer tube applicable to insect intercept net

Abstract

The invention relates to a collection transfer tube applicable to an insect intercept net. The collection transfer tube comprises a straight tube and an oblique tube, wherein one side of the middle part of the straight tube is provided with a transparent window, the oblique tube is connected to a position, corresponding to the transparent window, of the other side of the middle part of the straight tube, an included angle formed between the oblique tube and the straight tube is 45 degrees, and a transparent rainproof cover is arranged on the top end of the straight tube. The collection transfer tube applicable to the insect intercept net is made of a PVC (Polyvinyl Chloride) material and resistant to aging; the straight tube is provided with the transparent window, the insect has epitrophy and phototropism and can climb upwards along the oblique tube, after the insect enters the straight tube, the insect climbs towards the opposite side and a transparent insect separation plate, after the insect touches the insect separation plate, the insect can fall into a lower collection bottle, and a purpose of collecting the insect can be realized. By utilizing the upward-climbing habit of the insect, the phototropism of the insect is also considered, so that more insects can be collected.

Description

technical field [0001] The invention relates to a collection transfer pipe suitable for insect interception nets used in field investigation and specimen collection of agricultural and forestry insects. Background technique [0002] When studying insects in the biological field, it is usually necessary to use insect flight interception nets (usually Malai nets) to collect pests and their natural enemies. The flight interception net is composed of two parts, the net and the collector. Although the interception net has undergone many improvements and innovations over the years, its collection system is too simple. Currently, two white plastic collection bottles produced by Marris house are connected upside down. , the side opening of the upper collection bottle is directly connected to the intercepting net, or there is a very narrow connecting ring directly connected to the net. Such a collector has the following disadvantages, which seriously affects the collection effect: ...

AI Technical Summary

Problems solved by technology

Such a collector has the following disadvantages, which seriously affects the collection effect:

[0003] The collection bottle is too specific and difficult to replace, and the material is plastic, which is easy to age; due to the dark light in the plastic bottle, diurnal insects will linger on the top of the net front; the top of the net is close to the collection port or the distance is too close, once the insect antenna detects the smell of alcohol in the collection bottle, it can easily retreat, and will not fall into the trap by taking a step; moreover, this type of collection system is also fixed. The collection bottles connected upside down and upside down are designed with a fixed support frame, which can only be leaned against the corresponding thick and thin wooden piles or tree trunks, which is too rigid and extremely inconvenient to use in the field
