The cornfield to the west was sprayed only with water. The cornfield on the east received the same amount of water with a 10% solution of pesticide Z. The number of grasshoppers in the fields was recorded every week for 10 weeks. RESULTS: The number of grasshoppers in the west field treated only with water doubled after 10 weeks. The number of grasshoppers in the east field treated with pesticide Z declined by 50% after 10 weeks.
