Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of insect breeding, and more specifically, particularly relates to a device for obtaining fruit flies of different insect ages. Background Art
[0002] Fruit flies are a species of the genus Drosophilidae in the order Diptera. Females are 2.5 mm long, and males are smaller. Fruit flies are widely found in temperate and tropical climates around the world, and because their staple food is rotten fruit, they can be found in human habitats such as orchards and vegetable markets. Most species feed on rotten fruit or plants, while a few only feed on fungi, tree sap or pollen.
[0003] Fruit flies have a short life cycle, are easy to raise, reproduce quickly, have few chromosomes, many mutants, and are small in size, making them a very good material for genetic experiments. The study of fruit flies has played a key role in the development of genetics and evolutionary developmental biology, and has also promoted the development of many basic and applied disciplines such as neurobiology and cell biology.
[0004] In scientific research on fruit flies, ordinary test tubes or beakers are usually used for breeding. It is difficult to separate larvae, adults or pupae of different ages. Usually, they are picked up with a brush, which is not easy to operate. Summary of the invention
[0005] In order to solve the above technical problems, the utility model provides a device for obtaining fruit flies of different ages. By configuring the breeding device to be divisible into three sections, fruit flies of different ages can be obtained at different positions. The device structure is relatively simple and can be disassembled, and it is also convenient to assemble and use, thereby effectively solving the above technical problems.
[0006] The utility model discloses a device for obtaining fruit flies of different ages
[0007] The purpose and effect are achieved by the following specific technical means:
[0008] A device for obtaining fruit flies of different ages comprises an upper shell, a middle shell and a lower shell, wherein the upper shell is connected to the upper part of the lower shell through the middle shell, the lower shell is a cup-shaped structure, the upper and lower ends of the middle shell extend into the upper shell and the lower shell respectively, and the upper shell is a conical structure with a small upper part and a large lower part, and the top end is an open structure.
[0009] The middle shell is a straight cylinder structure with open ends at the upper and lower ends and two symmetrical vertical longitudinal seams in the middle.
[0010] The upper shell includes a cone top section, a cone bottom section and a connecting section. The cone top section and the cone bottom section are fixedly connected by the connecting section. The cone bottom section is cylindrical and placed on the top of the middle shell. The cone top section is a cylindrical structure with an opening at the top of the cone top section.
[0011] A method for using a device for obtaining fruit flies of different ages, the method comprising the following steps: 1. placing fruit fly larvae and feed in a lower shell; 2. inserting a middle shell symmetrically in two pieces into the lower shell, and then buckling the large end of an upper shell on the top of the middle shell. After the device is assembled, the flies can be raised; 3. adult fruit flies can be obtained from an opening by driving them from the bottom, while pupae will adhere to the wall of the middle shell and can be taken out by disassembling the middle shell. The fruit fly larvae are located in the lower shell and can be taken out by disassembling the middle shell.
[0012] The utility model at least has the following beneficial effects:
[0013] By setting the feeding device into a structure that can be divided into three sections, fruit flies of different ages can be obtained at different positions. The method for using the device is simple and easy to understand, does not require complicated operating steps, and can quickly complete the feeding and acquisition of fruit flies. Through the method for using the device, fruit flies of different ages can be obtained at the same time, which improves the experimental efficiency. The device can accurately separate fruit flies of different ages, avoiding confusion and errors that may occur in traditional methods. The method for using the device can prevent fruit flies from escaping and contaminating the laboratory environment, ensuring the safety of the experiment. The device can be reused, reducing the cost of the experiment, and also reducing waste during the experiment. BRIEF DESCRIPTION OF THE DRAWINGS
