This study aims to evaluate the toxic effects of insecticides on the foragers honey bee workers, Apis
mellifera jemenatica. It tracks the effects of the insecticides, Deltamethrin, Malathion and Abamectin through
the feeding by mouth, on the midgut epithelial layer, in order to show the histological changes. Histological
study on samples of the foragers honey bee workers, after exposure to insecticides for 24 hours, was chosen
as the average -concentration of the insecticide concentrations, which were used for each as follows:
Deltamethrin 2.50 ppm, Malathion 3.125 ppm and Abamectin 0.1 ppm, in addition to the control group.
Studying the effect of each insecticide individually and then comparing the reaction and impact of these
insecticides on the tissue of midgut has showed that the insecticide Malathion was more harmful to epithelial
tissue midgut in honey bees cells than Abamectin, while Deltamethrin had the least effect. Therefore, the life
of the foragers honeybee worker depends upon the health and safety of the entire members of the beehive, so
it is necessary to take into account, when using the application of insecticides, the continuity of life of the
entire society adoption of individuals beehive on worker bees layer depends on their life on this layer of the
bee community.
