Economic impacts on growers and consumers are a recurrent issue in the debate over changes in pest management systems and the regulation of pesticides. Pesticide benefits assessments are used to justify retention of labels covering uses of high-risk pesticides. When a pesticide is moving through EPA's Special Review process, rarely does the agency count "negative" benefits, like impacts on bees or the triggering of secondary pests. I would be interested in any analyses or estimates of the costs associated with poor pollination as a result of pesticide impacts on bees. Is there much literature out there on this topic?
