This study was conducted to detect and identify residues Exterminators (Deltamethrin) of pyrethroid (Pyrethroids group) and (Malathion) of organophosphates group (Organophosphates) in the body of an insect worker honeybees forager , using chemical analysis (Gas Chromatographic Analyses (GC)). Where was The study transactions are: treatment units (the control) is exposed to pesticides, treatment units offered for Deltamethrin pesticide concentrations 1, 2.5, 5, 10 ppm. treatment units offered for pesticide malathion concentrations 1.25,3.125,6.25,12.5 ppm. The results showed The technique of (GC-MS / MS) effective and high selectivity in the detection of residues of these insecticides in the samples tested. There was a positive correlation between the concentration of the insecticide and the value of the average residual pesticide inside the body of the insect. ranged from the lowest level of residues between 0.117 ppm and 0. 350 ppm concentration of 1.00 ppm and 1.250 ppm in each of the insecticides deltamethrin and malathion .The highest level of residues ranged between 3.660 ppm and 5.420 ppm concentration of 10.0 ppm and 12 0.50 ppm in deltamethrin and malathion, respectively. It could be argued that whatever the concentration of the pesticide used in the study, it found residues have deposited inside the bodies of forager honeybees worker . The life of a worker honeybee and longevity depend on the health and safety of members of the beehive, so it is necessary to take into account when the use of pesticides, the seriousness of their application in the continuity of the life of the entire society which in his life depends on this layer of worker bees.
