Nesting type wasp grafting breeding method

Abstract

The invention discloses a nest-dividing type wasp grafting breeding method, which belongs to the technical field of breeding, and can shorten the nesting time of other bee colonies through a bee colony nesting growth gap by utilizing a group of wasps with good growth vigor, and can directly lay eggs and expand nests on grafted honeycombs. In addition, the sick wasp colony with sick larvae can be saved, and if the sick wasp colony is not subjected to grafting breeding, the sick wasp colony grows slowly and even dies. According to the method, the breeding period of the wasps is shortened, and the breeding efficiency is improved.

Description

Technical Field

[0001] This invention belongs to the field of ecological aquaculture technology, specifically relating to a method for grafting and raising swarming wasps. Background Technology

[0002] Traditional wasp farming suffers from low reproductive efficiency, with weak colonies growing slowly or becoming diseased, resulting in low survival rates and economic losses. Current wasp grafting techniques mainly focus on multi-queen colony farming or grafting *Hypericum spp.* onto *Hypericum concaveum*. These grafting techniques are primarily for single colonies, resulting in only one colony after grafting, not multiple colonies. Furthermore, multi-queen colony farming often involves fighting between different wasp groups, leading to mortality and low survival rates. Therefore, there is an urgent need to develop efficient and standardized wasp grafting techniques. Summary of the Invention

[0003] The purpose of this invention is to provide a method for grafting and breeding swarming wasps.

[0004] The objective of this invention is achieved by including the following steps: (1) Single-crown grafting: Single-queen grafting is suitable for grafting early-stage bees into their hives. For example, early-stage bees have two layers of comb in their hives before they are wilded in late March or early April each year. First, collect the queen bee and worker bees with a collection cage, remove the larger layer of comb, divide it into four equal parts, and glue the smaller combs to the top of the nesting box with hot melt glue. Then, put the queen bee and worker bees into the nesting box. Select four other colonies of queen bees that have just built nests and are about to lay eggs. Collect the queen bees, remove the newly built nests, and then glue the honeycomb, which is divided into four equal parts, to the top of the nesting box where the nests were just removed, using hot melt glue. Continue to feed them for 15 days, and you can raise four small bee colonies, each with 15 small worker bees. Or (2) grafting larvae onto bee colonies: Grafting of colonies that have lost a large number of larvae after the emergence of worker bees is suitable for colonies. If a colony of worker bees suffers from acute larval loss disease, meaning all the uncapped larvae have fallen off, then a well-developed, wild-raised colony should be selected for brood division and grafting. Specifically, take a colony with 3-4 layers of comb, remove the largest two layers of comb, and divide them for grafting. Each division should contain 8-10 capped and 8-10 uncapped larvae. The removed two layers of comb should be used for grafting. Twenty small combs can be separated and glued to the top of the nesting box with hot melt glue (the nesting box should be thoroughly disinfected with a fungicide before grafting). Then, the queen and worker bees of the colony that has lost larvae can be placed into the nesting box containing the small combs. In this way, one healthy colony can quickly and efficiently save 20 colonies that have lost larvae after leaving the worker colony. When the number of worker bees in the grafted colony reaches 13-15, selective rewilding can be carried out depending on the weather conditions.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a swarm of healthy wasps. By leveraging the differences in nest-building and growth among the colonies, it can shorten the nest-building time of other wasp colonies, allowing them to lay eggs directly on grafted combs and expand their nests. Furthermore, it can rescue wasp colonies that have lost larvae due to disease. Without grafting and rearing sick wasp colonies, their growth is slow or they may even die. This invention shortens the wasp rearing cycle and improves rearing efficiency. Detailed Implementation

[0006] The present invention will be further described below with reference to embodiments, but this is not intended to limit the present invention in any way. Any modifications or substitutions made based on the teachings of the present invention shall fall within the protection scope of the present invention.

[0007] Example 1 (Single King Grafting Technique) In early April, a swarm of healthy wasps with two layers of comb was selected and collected using a suction-type wasp trap. The combs were removed, and the largest layer was divided into four equal parts. The smaller layer of comb and the four divided comb parts were glued to the top of the nesting box using hot glue. The collected queen bees and worker bees were placed in the nesting box with the smaller layer of comb. Four newly built queen bees, ready to lay eggs, were placed in the nesting cells containing the four comb parts. After 20 days of feeding, each nesting box contained one queen bee, 15 worker bees, and a number of eggs and larvae. On May 20th, the five colonies were released into the wild for rearing. All five colonies survived and thrived. In early September, the first harvest of bee pupae was conducted, yielding about 4 jin (2 catties) of pupae per hive. In late September, the second harvest of bee pupae was conducted, with an average yield of about 5 jin (2.5 catties). In late October, the third harvest of bee pupae was conducted, with an average yield of about 4 jin (2 catties).

[0008] Example 2 (grafting onto a colony of bees that has lost larvae) Twenty wasp colonies that were sick and had just lost larvae were selected. Twenty nesting boxes were prepared, and before grafting, they were thoroughly disinfected with a 2ml solution of chlorothalonil diluted in 0.5kg of mineral water and then dried. A colony with 3-4 layers of healthy comb was selected, and the largest two layers of comb were removed and divided into 20 smaller sections. Each section contained 8-10 capped larvae and 8-10 uncapped larvae. The combs were glued to the top of the nesting box using hot glue. The queen and worker bees from the colony that had lost larvae were then placed into the nesting boxes containing the smaller sections of comb. Honey and locusts were introduced as feed. After 30 days of rearing, 18 colonies survived, a survival rate of 90%. These 18 colonies were then released into the wild, and all 18 colonies survived and thrived.
