Problems solved by technology

At present, the breeding of bee species resistant to chalk disease is mainly judged by detecting the direct occurrence rate of chalk disease in the bee colony, and the direct incidence rate of chalk disease in the bee colony is determined by detecting the num

Embodiment 1

[0025] Embodiment 1: the detection of the clearance rate of the dead capper between the chalk disease patient colony and the healthy bee colony

[0026] In the experimental bee farm of Huajiachi Campus, Zhejiang University, three colonies of chalky bees (experimental group) and three colonies of healthy bees (control group) with basically the same colony were selected, and each colony was cut with a special honeycomb cutter. Four small capped spleens of 6.5*3.5 cm were taken out, and after being soaked in water for 24 hours, frozen at -20°C for 24 hours, liquid nitrogen, and needled, they were put back into the original group, and the remaining number of capped spleens was observed and recorded every 24 hours. Observed three times in a row. The t-test was used to statistically analyze the significance of the differences between the different treatment methods.

[0027] The percentage of dead caps cleaned by bees in the experimental group and the control group within 24h, 48...

Abstract

The invention discloses a method for testing the chalkbrood disease-resisting capability of swarms. The method includes the following steps: a sealed brood comb is cut from a tested swarm, soaked in water or frozen and then put back in the original place of the original swarm, the rate of the water-soaked or frozen sealed brood removed by the tested swarm is calculated after 24 to 48 hours, the chalkbrood disease-resisting capability of the swarm is strong if the removal rate is high, consequently, swarms with chalkbrood disease-resisting capability can be screened out, and the method can be used for breeding new bee varieties with the chalkbrood disease-resisting trait. The method has important application value, can predict the chalkbrood disease-resisting capability of a breeding queen bee or drone by testing the rate of the water-soaked or frozen sealed brood removed by the tested swarm, increases the accuracy of the choice of good chalkbrood disease-resisting queen bees and drone mating, and greatly increases the efficiency of breeding chalkbrood disease-resisting bees.

Description

technical field [0001] The invention relates to the technical field of bee breeding, in particular to a method for detecting the ability of bee colonies to resist chalk disease. Background technique [0002] With the progress of society, the value of bees to human beings has been paid more and more attention. The irreplaceability of its pollination and the nutritional value of corresponding bee products have also made people pay more and more attention to the development of beekeeping. Pests and diseases have always been a threat to beekeeping. biggest problem of industry development. The use of chemicals such as antibiotics can control the disease to a certain extent, but long-term use has weakened the resistance of bees, enhanced the drug resistance of pathogens, and forced people to increase the dosage, thus forming a vicious circle, endangering the environment, and also Causes drug residues in bee products. With the continuous improvement of people's requirements for f...
