5. Acceptance of bee larvae
The key factor is acceptance of bee larvae. The experienced workers/beekeepers can transfer bee larvae well. Acceptance of transferred bee larvae can reach 95% or higher. It is to say, that among 100 transferred bee larvae 95 of them can be accepted by bees. The accepted bee larvae will be fed with royal jelly. Bee larvae not accepted will be never fed. So it is very important that the royal jelly producer/beekeeper employs young experienced workers to transfer bee larvae or the technique of transferring themselves is very good.
