Pesticides not behind bee decline – study

Bee numbers have been plummeting since the 1990s, with pesticides usually taking the brunt of the blame.
But a three-year study in the United States has now shown that at real-world dosage levels, bee colonies are remarkably tolerant of insecticides; therefore, there must be something else driving what’s become known as colony collapse disorder.
Scientists at the University of Maryland subjected colonies to imidacloprid, the world’s most commonly used insecticide, and found it had no real effect on colony numbers when used at recommended levels.
