Agriculture is the backbone of most developing countries, but crops are badly affected due to increased pests. To control these pests, different types of pesticides are used that protect the crops. But on the other hand, it severely affects non-target, beneficial organisms and pollinators. Pollinators are important for the agricultural sector as they facilitate production as well as yield by pollination services. They showed its importance by pollinating 84% of crops worldwide. Bees are among the most common pollinators that are also badly affected during their pollination services which result in decreasing their population. The increase in the pesticide application lowers the population of pollinators which affects the agricultural yield. Decreasing the food supply due to shortage will ultimately increase the demand for food and feed also. This review provides information on the importance of pollinators, the usage of pesticides, and their effect on pollinators.
