    • COMING PALMTALK CHANGES - PLEASE READ   02/14/2017

      In the coming week (probably beginning this weekend), several major changes will be occurring with PalmTalk. The result will be short periods of complete closure, or of limited viewing (that is, no posting - but viewing still possible). These changes are major and unexpected complications are always a possibility. So, please be patient and bear with us. For those interested, the first phase will be a migration of the entire site to a new more powerful server. After this is completed, a major upgrade to the newest version of the forum software will then be attempted. It is hoped that these improvements, along with some new configurations of various parameters made possible with the new server capabilities, will result in an elimination of some error messages and glitches which have been plaguing various tasks and viewing recently. As with any upgrade there will probably be some new and/or changed features, or ways of viewing and/or using the forum. I anticipate these will be minor, and as always if there is anything confusing or needing explanation, we will set up a topic to discuss them.

Neonicotinoid pesticides tied to crashing bee populations,

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 .

Thanks for the info.

I wish I knew more about this malady to add anything to the discussion. I truly hope the experts are getting this understood and solved for all our sake.

We had a speaker at the last nativeplant society meeting who talked about colony collapse. This class of insecticide was mentioned. I don't use it.

Another thing he talked about was the stress of transporting the bees all over to pollinate groves of fruit trees and fields of vegetables. The problem is that there are so many more groves and fields that there are not enough bees to pollinate them. Then you have the farmers who don't want to manage their own hives. He spoke about the almod farmers in California. There are a lot more almod groves than there used to be and the owners find it cheaper to lease bees than keep their won. So the bees are transported from all over the country and are stressed out. So they flee the hives and go wild. They are transported from as far away as Maine for this purpose. Can't be good for them.

Also a hive can only support so many bees and use so much pollen.

So between the stress and the confusion caused by the nicitinoids and other pesticides/herbicides no wonder the bees are in decline.
