A device for collecting virgin fruit flies

Abstract

The invention discloses a virgin fruit fly collection device, and relates to a genetic experiment device, which solves the problems of complicated structure, high cost and trouble collection process in the existing virgin fruit fly collection device. The virgin fruit fly collection device comprises an insect feeding pipe, feed and an air ventilation pipe plug, wherein the feed is put at the bottom part of the insect feeding pipe, and the air ventilation pipe plug is embedded in the end opening of the feeding pipe. The virgin fruit fly collection device is characterized in that a virgin fruit fly collector is arranged in the middle part of the insect feeding pipe, is formed by sleeving a plurality of circular pipes, and is fixedly connected by a cross frame; the distance between the two adjacent circular pipes is slightly smaller than the height of an adult fruit fly; a center shaft which is positioned in the circular pipe at the center of the collector is inserted into a center hole of the cross frame, and enters the feed. The virgin fruit fly collection device is used for collecting the virgin fruit flies, and has the advantages that the structure is reasonable, the operation is simple, and the collection accuracy of the virgin fruit flies is high.

Description

technical field [0001] The invention relates to a genetic experiment of fruit flies, in particular to a device for collecting fruit fly virgin flies. Background technique [0002] Drosophila is a classic model organism with advantages such as short life history, many offspring, easy breeding, small number of chromosomes, and comprehensive genetic tools. It is widely used in the scientific research of genetics and developmental biology. Many important scientific discoveries are accomplished with the help of fruit flies, so fruit flies are a good experimental material. [0003] Drosophila genetic experiments require crossing different mutant or transgenic strains. The most critical step in hybridization is to select unmated virgin flies and then hybridize them with males of other lines. Selecting virgin flies is a very arduous task, which seriously restricts the efficiency of genetic experiments. [0004] At present, the method for collecting Drosophila virgins is mainly to...
