Preparing the frame of larvae for grafting is a delicate process that requires attention to detail to ensure the larvae remain healthy and viable for queen rearing. The key steps involve carefully removing the frame from the breeder colony, ensuring optimal lighting conditions for visibility, and selecting only the youngest larvae floating on ample royal jelly. Proper handling and the use of specialized tools are crucial to avoid disturbing the larvae during transfer.
Key Points Explained:
-
Removing the Frame from the Breeder Colony
- Gently brush bees off the frame to avoid agitation and damage to the larvae.
- Transport the frame carefully to the grafting location to prevent jostling.
-
Positioning the Frame for Optimal Visibility
- Place or lean the frame so that light illuminates the cells, making it easier to see and access the larvae.
- Avoid direct sunlight, which can overheat and harm the larvae.
-
Selecting Suitable Larvae for Grafting
- Only choose larvae that are under 24 hours old—these are the most viable for queen development.
- Ensure each larva is floating on a sufficient amount of royal jelly, indicating good health and nutrition.
-
Using the Correct Grafting Technique
- A grafting tool must follow the natural curve of the cell to gently lift the larva without touching it.
- The tool should slide under the larva’s back, keeping it undisturbed on its "raft" of royal jelly.
-
Maintaining Hygiene and Comfort
- Work in a clean environment to prevent contamination.
- Position the frame ergonomically to allow smooth, comfortable grafting without strain.
By following these steps meticulously, beekeepers can maximize the success rate of grafting and ensure strong, healthy queen bees.
