Peter, 
YOu are right that their are many interconnected factors.


1. treatments in general across te board that breach the co-dependency working relationships within a beehive of various mircro-organisms that have beent here for milions of years, besides breaching the food digestibility.
2. Artificial pollens.
3. Artificial syrup feeds.
4. Arificiial inbreeding parameters instead of old fashionied line breeding.
5. Migratory beekeeping so bees have no permanent home base for working out of.
6. Wrongful cell size that changes the breeding paramentes and foraging for food and propolis parameters. 
7. having to puty up with pesticide sprayings outside of a bee coloney.
8. NOt enough room for adequately being allowed to work and buildup for production.
