Sometimes the solution you need is right in your own backyard – or near it. Farmers who grow wheat and other grains have struggled since at least the 1800s to tame the wheat stem sawfly -- Cephus cinctus -- an insect that gets inside grain stalks and topples them, reducing yields. A variety of defensive approaches, from pesticide to crop rotation, have had only limited success. Now, scientists at the U.S. Department of Agriculture’s Agricultural Research Service are exploring a solution that leverages the sawfly’s natural foe to significantly reduce the harm it causes. If it works, it could become a critical part of the integrated pest management approach that USDA Agricultural Research Service researchers use to tackle agriculture’s insect enemies.
