It takes more than just introducing VSH queens into your operation. 
Colonies change their queens often. The drones they mate with have to 
carry VSH genes if the trait is to continue and be of use in your 
apiary. To do that takes years. Doable but not overnight.

I began with VSH in 2004 and now I'm getting pretty good results. I have 
all the apiaries in the area but 1, and they have good bees that I want 
in my mix. I've been introducing productive daughters of pure VSH queens 
into my mating area for the drone source and various vsh and carni 
daughters selected for production etc as the breeder queens. I'm looking 
forward to the next 5 years to see what happens as the selection process 
moves along.
