Fifty native cucurbit bees, Eucera pruinosa, were caught on 07/31/2025 in a neighboring pumpkin field and 25 were and released under each row cover treatment to pollinate the squash plants. The purpose of the row cover was to keep squash bugs and cucumber beetles away from the plants without using pesticides. All marketable fruit were harvested for commercial sales.
