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.
