Description

Technical Field

[0001] The invention relates to the technical field of bee genetic breeding, and in particular to a drone semen collector with a precision plunger pump. Background Art

[0002] Honey bees are typical social insects. A bee colony usually consists of a queen bee, thousands of drones, and tens of thousands of worker bees. Drones are haploid male bees that develop from unfertilized eggs and are responsible for mating with virgin queen bees. When artificially inseminating honey bees, it is necessary to force the drones to ejaculate. Drone semen is present in the mucus outer layer of the drone penis. The amount of drone semen collected from sexually mature bees is only 0.9-1.1 microliters per bee. The amount of semen is scarce, and the boundary between semen and mucus is extremely unclear. Novices often confuse semen with mucus. Once mucus is injected into the queen bee, it will cause the queen bee to die.

[0003] Sufficient and high-quality drone semen is a prerequisite for artificial insemination of honey bees, and drone semen collection tools are constantly improved with the development of artificial insemination technology. The syringes installed on the queen bee insemination instrument commonly used for current drone semen collection are most representative of the syringes of a queen bee artificial insemination instrument (CN201120324990.6), the fine-tuning syringe of a queen bee artificial insemination instrument (CN201520596874.8), and the micro-injector of a queen bee artificial insemination instrument with a precision three-dimensional guide rail and its use method (CN201510551609.2). The syringes in the above patents all rely on manually pushing the push rod of the sample injector to control the in and out of semen, and the minimum scale of the syringe is 1 microliter. There is a slight error in the force during manual operation, which is very easy to suck in mucus, affecting the quality of the collected semen.

[0004] In addition, the existing technology relies on fingers pulling the metal rod of the syringe to achieve semen collection. Conventional syringes are made of glass and the pull rod is made of metal. When the fingers pull, the metal rod will produce friction with the glass tube. In order to ensure the sealing of the syringe, the syringe manufacturer designs the metal rod to have a tight contact surface with the glass tube. Since the metal rod and the glass tube are made of different materials, the friction is relatively large. Based on the characteristics of drone semen being scarce and viscous, the operator must gently pull the metal rod when absorbing semen. It is necessary to find a balance between the pulling force and the friction force. This is difficult for beginners to master and requires users to practice repeatedly over a long period of time.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a drone semen collector with a precision plunger pump to solve the above technical problems.

[0007] The present invention is achieved in that:

[0009] The control system sends an electrical signal to start the plunger pump, and the suction of the plunger pump sucks the drone semen into the semen collection needle to achieve semen collection. The control system can realize the automatic operation of the drone semen collector, which has very low operating requirements for the operator and can master the semen collection technology without repeated practice. The use of a high-precision plunger pump can accurately control the amount of semen collected, avoiding the inaccuracy of existing semen collection devices, which easily mixes mucus with semen and causes the death of the queen bee.
