Harvard Study: Honeybee decline due to popular insecticides called neonicotinoids,

Science Recorder - A new study by researchers from the Harvard School of Public Health says that the widespread demise of honeybees is due to the use of a class of popular insecticides called neonicotinoids, combined with cold temperatures during the winter months. Thee deadly combination of insecticides and cold weather causes honeybees to abandon their hives–a phenomenon known as Colony Collapse Disorder. Over recent years, Western countries have lost between 30 percent and 70 percent of their honeybee populations, scientists say.

The new study replicates earlier research by same research team that found a link between CCD and low doses of imidacloprid, another neonicotinoid insecticide.

"We demonstrated again in this study that neonicotinoids are highly likely responsible for triggering CCD in honeybee hives that were healthy prior to the arrival of winter," said lead author Chensheng (Alex) Lu in a statement.
