Abstract

There is no clear single factor to date that explains colony loss in bees, but one factor proposed is the wide-spread application of agrochemicals Concentrations of 14 organophosphorous insecticides (OPs) in honey bees (Apis mellifera) and hive matrices (honey and pollen) were measured to assess their
hazard to honey bees. Samples were collected during spring and summer 2013,from 5 provinces in the middle delta of Egypt and from 7 randomly selected colonies in central Saskatchewan during summer 2013. LC/MS-MS was used to identify and quantify individual OPs by using of a modified Quick Easy Cheap Effective Rugged Safe (QuEChERS) method. In Egypt.
