Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that in the existing paederus paederus secretion collection technology, the living insects are easily damaged when the secretions are collected manually, which leads to the decrease of the survival rate of the insects, the inability to repeatedly take poison and the secretion of toxins from the insect body In order to solve the problems of less collection, low efficiency, and easy pollution of the environment, a device and method for collecting secretions of living paederus grandis are provided.

Embodiment 1

[0033] Embodiment one, such as figure 1 , figure 2 , image 3 As shown, the embodiment of the present invention provides a large paederus secretion collection device, comprising a collection bottle 1, a collection body 2, a live worm inlet section 3, a live worm outlet section 4, and a crawling passage (inclined section 5, Single one-way section 6), carbon support film 7, manual pressing mechanism 8, ceramic piezoelectric device 9, conductive plate 10, wherein the collection body 2 is provided with live insect entrance section 3, live insect exit section 4, and the interior of the collection body is equipped with There is a crawling passage that runs through the entrance section of live insects and the exit section of live insects. The crawling passage located at the exit section of live insects is equipped with a pressing mechanism and a secretion collection structure. The pressing mechanism presses the insect's head or chest to make its tail secrete defensive secretions T...

Embodiment 2

[0042] Embodiment 2. The collection body of this embodiment is roughly the same as that of Embodiment 1. The difference between the two is that the pressing mechanism of this embodiment is an automatic pressing structure, including an infrared induction relay, a miniature electromagnet, and a silicone pad at the front end of the iron core. When the worm crawls to the infrared sensing area, it can trigger the miniature electromagnet core to press down and lift it up after 5s. By using the infrared sensing relay, once the live insect is detected, the infrared relay receives the signal and the relay switch is automatically closed (switch and relay k are packaged in one device), after the power is turned on, the micro electromagnet is powered on through the power supply interface to press live insects, refer to Figure 4 circuit schematic diagram.

[0043] The working principle of the present invention is as follows: the negative pressure suction provided by the vacuum cleaner suc...

Abstract

The invention relates to a cryptopterus salmoides secretion collecting device and method. The device comprises a collecting body, a live insect inlet section and a live insect outlet section are arranged on the collecting body; a crawling channel penetrating through the live insect inlet section and the live insect outlet section is arranged in the collecting body, the crawling channel located atthe live insect outlet section is provided with a pressing mechanism and a secretion collecting structure, the head or the chest of an insect is pressed through the pressing mechanism, the tail of theinsect secretes defensive secretion, and the secretion collecting structure is used for adsorbing and collecting the secretion. The width of the crawling channel of the live insect outlet section only allows one insect to pass through. The device has the advantages that the device is simple in structure and easy to operate, insect bodies can be effectively prevented from being damaged when secreta are manually collected from living cryptopterus salmoides, the toxin collection amount can be effectively increased, the toxin collection efficiency is high and toxins are not prone to polluting theenvironment.

Description

technical field [0001] The invention relates to the technical field of laboratory biological culture and manufacturing equipment, in particular to a device and method for collecting paederus grandis secretions used for quantitative analysis of biological active components. Background technique [0002] The large paederus is an insect belonging to the family Staphylinidae of the order Coleoptera, and it is one of the largest species in this group. There is a defensive gland that can be turned out at the end of the abdomen of the adult paederus. When under stress and attack, the adult will bend its tail and turn the gland out at the same time, secreting a strong sour smell from the end of the tail. A milky white liquid with a strong odor, which is used to smear or threaten predators by vigorously wagging its tail. Early data show that the liquid contains volatile compounds, mainly containing chemical components such as dihydronepetalactone, iridodial, actinidine, (E)-8-oxocit...
