Once a queen has mated, her supply of stored spermatozoa is finite, and typically begins to run short after two seasons of broodrearing in a large colony (she’ll last longer where seasons are short, or in a small colony). This depletion typically occurs in the late summer of their secon...

Dr. Eric Mussen15 has noted that in some areas of the California foothills, previously common native plants no longer supply fall forage.Biological plausibility: The weather is well known to be a huge factor in colony survival, due to its indirect effect upon plant production of nectar and ...
the rapid turnover of the forager population, a strong, healthy colony can generally shrug off a one-time hit to its field force from a fast-acting, short residual insecticide spray, provided that those bees die outside the hive and do not contaminate the nest’s pollen and honey stores....
But then, since thelead investigator seemed to be eager to “prove” that CCD is caused by imidacloprid, he dreamed up the fantastic scenario that in the winter of 2006/2007 that for some inexplicable reason the nation’s supply of HFCS was contaminated with high levels of imidacloprid. My ...
What were the causes of this year’s bee shortage? As Rather says, “Everyone has an opinion.” The question is whether those opinions are based upon fact! So let’s go over the events leading up to the bee supply debacle.Setting the Stage...
