Link between insecticides and collapse of honey bee colonies strengthened

Summary: Two widely used neonicotinoids — a class of insecticide — appear to significantly harm honey bee colonies over the winter, particularly during colder winters, according to a new study from Harvard School of Public Health (HSPH). The study replicated a 2012 finding from the same research group that found a link between low doses of imidacloprid and Colony Collapse Disorder (CCD), in which bees abandon their hives over the winter and eventually die. The new study also found that low doses of a second neonicotinoid, clothianidin, had the same negative effect.
Further, although other studies have suggested that CCD-related mortality in honey bee colonies may come from bees’ reduced resistance to mites or parasites as a result of exposure to pesticides, the new study found that bees in the hives exhibiting CCD had almost identical levels of pathogen infestation as a group of control hives, most of which survived the winter. This finding suggests that the neonicotinoids are causing some other kind of biological mechanism in bees that in turn leads to CCD.
The study appears online May 9, 2014 in the Bulletin of Insectology.
“We demonstrated again in this study that neonicotinoids are highly likely to be responsible for triggering CCD in honey bee hives that were healthy prior to the arrival of winter,” said lead author Chensheng (Alex) Lu, associate professor of environmental exposure biology at HSPH. http://www.sciencedaily.com/releases/2014/05/140509110713.htm
Soooooo, the funniest thing I heard. That bastion of Republicanism, Texas. How many top jobs were held by who?
Texas Governors…
1 Unionist.
1 Independant (Sam Houston Evicted from office due to his refusal to swear an oath to the Confederate States of America).
5 Republican
39 Democrat
Who knew?
Most of those dems were Dixiecrats – a vestige of the civil war republicans – the party of Lincoln – were almost completely shut out south of the Mason-Dixon Line right up until Nixon unlocked them via the southern strategy.
Mother’s Day !!!
Give Mom a call or stop by if it’s possible, even if empty handed!
Some MOMS, like my own carried their CROSSES on this plane of existence without complaint.
A visit from any one of her offspring, at any time, washed away any pain she carried in her own sorrow for the sake of the one who was forever different.
Thank Kate, for SDA, you are the best!

Nof60 (LAS) you use Harvard as a reference for science? That’s like using HuffPo for conservative views. And BTW,that study has been proven totally BS. And no link.Look it up yourself,as you tell others to do,well,I ain’t Google.
If Obama had a son, he would be in Boko Haram. And he would look like Trayvon Martin.
This summer, those who grapple with zebra mussels will be watching Manitoba, where officials are trying to stop an invasion with a unique experiment.
Once the winter ice recedes on Lake Winnipeg, a silk curtain will be lowered to the lake floor to seal off four infested harbours. Liquid potash will then be pumped into the water until it reaches a lethal concentration for the mussels and clogs their gills.
The technique has been tried in a closed quarry, but this is believed to be the first time liquid potash has been used in open water. https://ca.news.yahoo.com/eyes-manitoba-tries-blast-zebra-mussels-unique-experiment-140013689.html

Surprised he didn’t also play goal and register a shutout.
The event may not be “news” – over 75 years have passed – but the film of the Hindenburg airship disaster we have been watching all these years has a companion not seen until recently. Taken from a bit to the side, it shows things – potential clues – not visible in the head-on film we know.

Hey, if you live in a police state, they can come and take it from you no questions asked.
The police gets to keep the money.
A “no can lose” proposition, from the police state perspective.
