The Tomato Fruitworm, also known as Helicoverpa zea, is a common pest that primarily affects tomato plants. This caterpillar is green or brown and can grow up to 1.5 inches long. It feeds on the fruit, leaves, and flowers of various plants, leading to significant damage and reduced yields. These pests are most active during warm months and can be found in gardens and agricultural fields. Effective management strategies include crop rotation, using natural predators, and applying insecticides when necessary to protect tomato crops from infestation.
