The New “Harvard Study” on neonics, May 2014

Dr. Lu of Harvard Medical School, who has no background with honey bees, attempted to run an experiment in 2012 (The 2012 Harvard Study) that would “prove” that the seed treatment of corn put so much imidacloprid into high fructose corn syrup that the feeding of such was the cause of CCD.  Although both the notion and the way in which the “study” was run were preposterous, and were dismissed by all serious bee researchers, it nevertheless got a lot of press.

Thoroughly chastised by the bee research community for his amateurish attempt to perform bee research, Dr. Lu recently released yet anther study, again in a journal practicing questionable peer review.


Update: May 16, 2014

My criticisms of Dr. Lu’s studies have raised a great deal of interest.  I’d like to explain my position.  As a beekeeper who makes his living from having healthy colonies of bees, I am acutely interested in the causes of colony morbidity and mortality.  Without a doubt, pesticides can cause colony morbidity or mortality, which I’ve covered in my Sick Bees series of articles (e.g., The Slaughter of the Innocents).  The neonicotinoid class of insecticides are no exception, and I’ve detailed problems associated with them in The Neonicotinoids–Trying to Make Sense of the Science.  But I’ve also done on-the-ground reality checking on the effects of neonics upon those bees and beekeepers at Ground Zero of neonicotinoid use in The Extinction of the Honey Bee.  Although I initially suspected that neonicotinoids may have been a likely cause of Colony Collapse, my extensive research does not support that hypothesis.

I’ve also run (or participated in) a number of studies on the actual causes of colony collapse, and have published a widely-accepted model of its progression (A Model of Colony Collapse).  Any of several factors  may be involved in colony collapse, including pesticides.  In short, sudden colony depopulation is typically due to the troika of varroa, viruses, and nosema, exacerbated by poor nutrition, beekeeper-applied miticides, and chilling–which may...


(Note from LACBA Secretary, Stacy McKenna: "Actually, the article is pretty good, particularly in that it points out that the research study is pretty crappy. The above is Randy Oliver's take on the "research".")
