Big Ag Will Kill Us Now

The good folks at I F%$#ing Love Science point us to a study that strongly indicates that neonicotinoid pesticides cause colony collapse disorder in bees:

A new study claims to have pegged neonicotinoids as the definitive cause of Colony Collapse Disorder. But does the data really justify the conclusions?

European honey bees are incredibly important pollinators. Unfortunately, they're disappearing at a rapid rate due to a phenomenon known as colony collapse disorder (CCD). What actually causes CCD isn't completely understood. CCD has confused scientists since it was first described, or had its name changed, in 2006. It is likely caused by a number of different factors, working together - however, there has been a large focus on a certain group of insecticides known as neonicotinoids. In December of 2013, in an attempt to mitigate their involvement, the EU implemented a two-year memorandum on three commonly used insecticides in the neonicotinoid family. Many, including their own government, criticized the science behind the moratorium.

There is a desperate need for new studies to accurately test the different variables involved in CCD. New research from Dr. Alex Lu attempts to peg neonicotinoid insecticides as the underlying cause of CCD. The study set up 18 hives to test the effects of two neonicotinoids, clothianidin and imidacloprid, from 2012-2013. Six colonies were selected from three different sites in central Massachusetts, and sublethal doses of each insecticide were given orally to treatment hives via a syrup solution. Six of twelve treated colonies abandoned their hives while only one of the six control hives abandoned theirs. Neonicotinoids obviously do not help bees, but whether this study has found them to be the ‘smoking gun’ isn’t exactly as clear as many are making it out to be. Only 18 hives were used in this study which is too small of a sample size to control for other variables and definitely too small to form a definitive conclusion as to the affects of neonicotinoids. The way he tests for CCD-like symptoms is not a definitive indication that is occurring. Hive abandonment is not automatically CCD. Honey bees may abandon their hives for any number of different reasons, and this study doesn’t control for any of them.

This is why things like pesticides should be proved safe before use, and not allowed until proved they are unsafe, as is the USDA's policy in the United States.

This is a small study, and as such, it should not be the sole basis of regulatory policy, but I do think that this is a good justification to throwing a few million dollars at a larger study, before we lose our almond, avocado, apples, peaches, pears, etc.
