Dr. Johnson's program focuses on understanding the relationship between pollinators and their environment, with an emphasis on the effects of pesticides and understanding the physiological basis of pesticide toxicity. Insect pollinators are vital for the production of many fruits, nuts and vegetables, including apples, blueberries, almonds, tomatoes and pumpkins. These crops are also vulnerable to pests and diseases, which are often controlled through the use of pesticides.  However, pesticides may be toxic to insect pollinators, setting up a conflict between the need for pollination and the need for pest and disease control. In our lab we are seeking to understand how to protect pollinators from the pesticides and other toxins they encounter. The managed European honey bee, Apis mellifera, serves as a model pollinator for toxicological testing.  While the honey bee is the most economically important pollinator in the U.S. and serves as an excellent model species, we are also interested in understanding pesticide toxicity in other pollinating insects as well.
