Article states that the EPA has a 'review that's currently under way.'. pretty sure this is the same class of insecticide that is used to inject the Wiliwili trees in Hawaii to combat erythrina gall wasp, also used here to inject cambium (?) layer of other Erythrina species to fight tip borer. I have never talked to anyone who is 'in-the-know' who can tell me if injecting an erythrina (coral tree)helps against tip borer. I know first hand that 'systemic drench' (soaking the roots) doesn't do squat.
The French study referred to has been out a number of years, The British study is newer. I had never seen the much more convincing Bumble bee data.
I started talking about the decline in honey bees on my property years ago when most people were saying there was no problem. Now I can go out in a large field covered with paintbrush,buttercup,etc., and see practically no honey bees. I don't see any bumble bees at all now. I see carpenter bees. Next time I get a chance to shake a swarm into a box , I think I'll try it. There used to always be a hive of bees in a log or barrel around here, but the last 2 nests didn't survive more than a year .
