Interesting discussion..
In many respects the answer is the small scale Beekeeper .. New Zealand and EFB would be one example .. it was the beekeepers who decided that something need to be done in the absence of any Government program after they removed it.
Getting a consensus may prove difficult
I'm willing to throw my hat into this ring .. I had volunteered some sites for a recent university study but they weren't quite in the right locations.
Logically small scale producers have the potential for a higher overall impact.
Several points to consider.
Wild populations are more likely to be influenced genetically by small scale producers....
The reasoning behind this is wild/semi wild populations near small scale producers, are more likely to come into contact with genetics from the keepers Bees. A large number of small scale producers have 'day jobs', therefore a limited amount of days in a week in which to visit the hive. This may be one reason a small scale producer is more likely to experience a 'swarm', the increase in swarm probability directly affects the probability of genetic influence on wild/semi wild populations near by.
Wild populations are notorious as acting as reservoirs for pathogens, even though the population itself is often capable of surviving a larger infestation than a 'domestic' colonie.
Conversely while the small scale producer has a more limited number of days to attend hives, the mean time spent inspecting a hive tends to be higher than that of a commercial operation. This often leads to quicker detection of problems, in a commercial operation of any meaningful size, there is often not the luxury of time to sit and watch Bees! Small scale producers are far more likely to 'Bee gaze!'.
It is easier and less expensive for a small producer to change method and protocol and invest in a new product. On a large operation it can be common to buy in bulk or indeed to have a contract of supply for products, this allows them to negotiate better prices.
If a new product comes to market and application is different to what they currently use, then the larger operator's also have the cost of training to take into consideration.
There are other reasons including software changes for the very large producers etc.
The small scale producer simply reads the label and applies the treatment.
Large scale operators are more likely to take a product up after seeing the efficacy demonstrated by smaller scale operators, in this case it would be reasonable for them to want to see results before using a product and potentially risking a vast amount of money if they loose a high percentage of their operation.
Engaging large scale operations can be difficult, ultimately they are run as a business and meeting after meeting has to take place, contracts need to be drawn up and any number of decisions taken, for example in the event a trial product causes fatality who is responsible? Are there any insurance issues relating to non certified products? The list can be endless, however it is surprising just how fast they can move once something is proven to work!
I have mentioned elsewhere that one of the most common treatments for Varroa (Thymol) was discovered and first used by a small scale Beek working on his own, admittedly later on he became a large scale producer and is responsible for many of today's practices.
The number of small scale producers is largely a guesstimate, i have been surprised many times to find hives in gardens etc that i suspect few people even know exist, not all small scale producers join clubs or forums. many simply keep a hive and have done for many years, often these people rarely talk their hobby so it is extremely hard to know exactly how many hive/small producers are out there. With that said the same 'shy' Beek's still buy a treatment if they encounter a problem.
Finally....................
We (academia/industry) have and still do work with large scale producers, without them much of the current data would not be available. However to date limiting research to the larger operations has not resulted in ANY decline of the level of disease found. This is one reason research is now starting to focus and turn to the smaller producer, it would be illogical to continue down the same paths with the same results. More simply put.....As a research group we feel it's time to try a different approach.
I would like to apologize for the long post, but i would also like to say that so far i have been pleasantly surprised at the level of willingness from members here to offer to help, i think this alone justifies our decision to take this route.
