Book Description
"The corn earworm (Helicoverpa zea) is the most destructive insect pest of sweet corn in the US and has been noted to be one of the most destructive plant feeding insects in the world. Preferred crops for earworm include corn, tomato, sorghum, vetch, and cotton. On these crops, the pests are called corn earworm, tomato fruitworms, sorghum headworm, vetchworm, and the American cotton bollworm, respectively. Corn earworm will also feed on numerous other crops, including alfalfa, oat, soybean, sunflower, asparagus, cabbage, cantaloupe, cucumber, eggplant, bean, pea, pepper, potato, pumpkin, and watermelon as well as some weed hosts. Corn earworm occurs throughout the Americas, being a native insect pest occurring from Argentina in the south to Canada in the north. The goal of this publication is to discuss the biology of corn earworm and to aid commercial producers and crop consultants by providing scouting techniques and control options for this pest in sweet corn."--Abstract.
