> "the overuse of pesticides leads to resistance"
It was pointed out to me that this statement is too broad. Overuse of pesticides *can* lead to resistance. One thing is certain, though, resistance to a certain pesticide requires use of that pesticide.
In terms of evolution, the idea is that if you kill all the susceptible individuals, then all that is left is resistant individuals who can thrive due to lack of competition. Again, this *can* happen but it does not inevitably happen. No resistance has surfaced re: organic acids, although these may not always be effective due to other factors.
Personally, I would have been very happy to use formic acid as the only treatment, but it is highly dependent on environmental conditions (temperature, ventilation, etc.) My routine now is to use formic when it is warm enough and follow up with Apivar in the fall. Of course it's expensive but I try to do everything I can for my bees, short of moving them south for the winter.
