To pick up on Kathy's comments...
Studies also show that whether you treat or not, colony loss is not tremendously different.
There are even studies that show that mites have so well adapted to the chemicals (we have generated super-parasites), they actually do better on the chemicals. A little like feeding on them to get their "super-power"!
There are studies that say this, studies that say that, and studies that say the opposite.
There are people who believe in small cell as solution; there are people who believe small cell does not work. Both are entrenched in their belief. You have to make your own mind and believe, i guess!!! But that is outside of studies and science, it's a little bit like religion. :evil:
