Problems solved by technology

However, due to the influence of many factors such as the dormant environment and the bumblebee queen's own resistance, the survival rate of bumblebees overwintering is low, which leads to a low annual colony establishment and cannot meet the needs of artificial breeding and pollination.

Embodiment 1

[0052] A method for improving the overwintering survival rate of bumblebees, comprising the steps of:

[0053] 1. Virgin queen bee mating

[0054] Place the sexually mature virgin queen bee in the mating cage, put 1-2 drones, and mate;

[0055] 2. Prepare beehives for overwintering

[0056] Prepare beehives for overwintering (multiple independent small beehives can be used; or use beehives with multiple independent units, each unit is isolated from each other, and each unit has vents, feeding ports, etc.), clean up.

[0057] Weigh the following raw materials: Acanthopanax 35g, mint 25g, honeysuckle 25g, licorice 25g, houttuynia cordata 8g and purslane 8g, mix and crush through a 10-mesh sieve, add 1200g of water, heat and extract for 4 hours, during the heating process, the beehive Suspended in traditional Chinese medicine steam for fumigation.

[0058] After the fumigation, the beehives were ventilated for 3 days, dried, and dry filter paper was placed in the box, and plac...

Embodiment 2

[0088] Use the method of Example 1 to carry out the overwintering experiment of Bombus grandis, and set the control group:

[0089] Control group 1: the feed was replaced with rapeseed pollen and 40% sucrose water, and the rest of the steps were the same as in Example 1.

[0090] Control group 2: Feed for 10 days before overwintering, take out the worker bees, directly lower the temperature to 4°C, and enter dormancy; when recovery is required, directly raise the temperature to 14°C, and then rise to 28°C after 1 day, and the rest of the steps are the same as in the example 1.

[0091] After recovery, the feeding was continued and observed, and the experimental results of dormant queen bee survival rate (the number of successfully recovered queen bees / the number of dormant queen bees) and the colonization rate (the number of normal spawning queen bees after recovery / the number of dormant queen bees) were counted, as shown in Table 1.

[0092] Table 1

Abstract

The invention discloses a method for improving the overwintering survival rate of bumblebees. The method includes the following steps that (1) virgin queen bee mating is carried out, specifically, thevirgin queen bee is placed in a mating cage to enable the virgin queen bee to mate with a drone; (2) feeding before overwintering is carried out, specifically, the queen bee after mating is moved ina fumigated beehive, feeding is carried out at 26-30 DEG C and the relative humidity of 50-70% for 1-2 weeks, and a feed is daily changed; (3) dormancy of the queen bee is carried out, specifically, the temperature in the beehive is gradually lowered to 2-5 DEG C at a temperature lowering rate of 1-2 DEG C / day to enable the queen bee to be a dormant state; (4) after-overwintering feeding is carried out, specifically, when the outdoor temperature is greater than 15 DEG C or before the flowering period of crops in a greenhouse, the temperature in the beehive is gradually increased to 26-30 DEG Cat a temperature increasing rate of 1-2 DEG C / day, feeding is carried out, the feed is daily changed, so that the queen bee nests to lay eggs, and a new bee colony is established. According to the method, the overwintering survival rate and colonization rate of the bumblebee can be improved.

Description

technical field [0001] The invention relates to the technical field of bumble bee breeding, in particular to a method for improving the overwintering survival rate of bumble bees. Background technique [0002] Bumblebee is an insect of Hymenoptera, Bee superfamily, Bombus genus, and is an important pollinator of various plants, especially leguminous and solanaceous plants. [0003] The bumble bee queen usually leaves the original bee colony in autumn and goes dormant, and wakes up in May of the following year when the weather warms up, builds a nest and lays eggs, and establishes a new bee colony. However, due to the influence of many factors such as the dormant environment and the bumblebee queen's own resistance, the survival rate of bumblebees overwintering is low, which leads to a low annual colony establishment and cannot meet the needs of artificial breeding and pollination. [0004] Therefore, how to improve the overwintering survival rate of bumble bees is an urgent...
