Also, your link cites, as the basis for saying that declines in honeybee populations aren't a problem in Australia, a letter called 'A regulatory perspective from Australia' by a guy named Davies from the Australian gov't. I gotta mention a couple of things that didn't sit right with me about it.

that paper about the French study that tracked individual bees that Davies cites at the end of his spiel .... like, it found that while neonicotinoids caused significantly increases rates in worker mortality, the colonies were able to compensate by cutting back on drone production and scaling up worker production. It kind leaves off by saying that colonies with high exposure to the pesticides they looked at were able to compensate for the damage in the short term, but that it seemed like there could be more long term effects that they weren't able to see play out in the time frame of the study.

But the way he cites it is to basically argue something like: 'even if neonicotinoids do kill bees, this study says colonies can adapt to the losses'. I don't think that's really what the paper said at all, though. It just said that over the course of the 2 seasons the study ran, the experimental colonies were able to adapt, but they ended up looking like colonies that had poor access to forage even though they had plenty to eat. He mentions the paper briefly at the end of his letter, it isn't really vital to the main thrust of what he was saying, but it just kind of bugged me.

More importantly though, he seemed waaay quick to make a global conclusion based on the situation in Australia. Whoever wrote the press release that you linked was smart enough to say

Unlike in other countries, and because of our unique ecosystem, the scientific information available indicates that managed and wild honey bee populations are not in decline in Australia.

But he isn't. He gives us

it is not correct to conclude, as many articles and reports have done, that Apis honeybee populations are in global decline.

As his conclusion to several paragraphs describing what the situation in the totally average and not at all unusual land of Australia is like, That's fucking stupid, dude. And just factually incorrect, regardless of what role neonicitinoids play in the decline.

I know this is excessively verbose, but I don't think link you posted says a whole lot about what's going on in Brazil.
