    Insect pollinators provide many essential ecosystem services including pollination, and many others. However, pollinating insects are currently facing potential threats on an unprecedented scale with many species facing decline. Honeybee Apis mellifera comprise nearly 68% of those affected insect pollinators. Irrational Insecticides application, with special reference to neonicotinoides group is one of the main causes of this decline. The main objective of the current study is to investigate the impact of some insecticides application on the activity of broad bean flower-visiting bees. Tested inseticides were thiamethoxam, acetamiprid, thiacloprid (neonicotinoids), spinosyns A and D, beside some organophosphates. Changes in the daily activity of bees visiting broad bean flowers following insecticide application was recorded and compared to their activity before application, throughout until the end of blooming season.
