Abstract

Varroa destructor is a kind of parasitic mite that seriously endangers the western honeybees. It has become the biggest pest threat to the agiculture of the world. At present, chemical drugs such as mite powders are worldwidely used to control the infection of Varroa destructor. While these anti-mite drugs may increase drug resistance of Varroa destructor and pollution of bee products. Although many biological methods have been adopted, the effect on mite control is not satisfactory. This paper discussses the use of plastic mould to modularize the movable honeycomb frame and make the modularized honeycomb into a biological trap. Based on the biological characteristics of Varroa destructor reproduction and its parasitic characteristics and reproductive regularity, a movable nest frame with plastic mould was modularized and made into a biological trap. Then the biological trap was set up in every colony to trap and kill Varroa destructor in a planned way, and the male pupae are harvested at the same time. The results showed that after a series of reciprocating trap, the trapping rate decreases geometrically, and the sex ratio was well controlled. This biological trap is of practical significance to reduce the damage of Varroa destructor to bee colony and to improve the economic benefits of bee farmers.

Highlights

  • Before its renaming in 2000, Varroa destructor was known as Varroa jacobsoni Oudemans

  • The third reason is that bees often twist their bodies after being parasitized by Varroa destructor to get rid of them, resulting in exhaustion and eventual death; Fourthly, the developing colony is weakened by the parasitic population of wasp mites; Fifthly, the bee colony is not treated in time before rearing winter bees of suitable age in autumn, and the bee colony is disturbed by Varroa destructor, which makes the bees unable to cluster and the bee colony can not survive winter safely, and even results in serious losses. [11]

  • Ambushing Time Let the Varroa destructor get into the biological trap as much as possible for 15-16 days, take it out and set up a new trap at the same place

Summary

Introduction

Before its renaming in 2000, Varroa destructor was known as Varroa jacobsoni Oudemans It is one of the most threatening bee diseases and insect pests in the world beekeeping industry. It belongs to the order Parasitic Mites and the family Vamitidae (hereinafter referred to as "Varroa destructor"). In our research, we have found a new practical method, which can kill Varroa destructor and harvest male pupae at the same time. This biological method is easy to operate and can efficiently reduce the damage of Varroa destructors to bee colony. It is worthy to spread worldwide to improve the economic benefits of bee farmers
