Here we demonstrate for the first time that exposure to field-realistic concentrations of neonicotinoid pesticides during development can severely affect queens of western honey bees (*Apis mellifera*). In pesticide-exposed queens, reproductive anatomy (ovaries) and physiology (spermathecal-stored sperm quality and quantity), rather than flight behaviour, were compromised and likely corresponded to reduced queen success (alive and producing worker offspring).

Neonicotinoid pesticides severely affect honey bee queens




   
I am extremely curious,  have these types of studies been done on any of the alternatives at field realistic doses,  
Such as chemicals used for mosquitoes
Pyrethroids
Sulfides,

Or the old stand by Atrizine??
