COMPARISON OF HONEY-BEE (HYMENOPTERA, APIDAE) MORTALITY AS A RESULT OF DIURNAL AND NOCTURNAL APPLICATIONS OF DIMETHOATE

Bee mortality from applications sprayed at night, although significantly lower than the applications sprayed during the day, is probably still at a level unacceptable to beekeepers. -from Authors
