Host: burley tobacco (Nicotiana tabacum (burley type)
Description: The tobacco tomato hornworms, Manduca sexta (Linnaeus), and Manduca quinquemaculata (Haworth), are potentially the most destructive insect pests of tobacco. They chew irregular holes in leaves and often feed along leaf margins. Newly hatched larvae are 1/4-inch long, pale green with a large horn at the posterior end. Larger larvae (up to 4 inches) are bright green in color. The tobacco hornworm larva has seven white diagonal stripes on each side and a curved red horn. The adult, a dark gray moth, has six round, orange-yellow spots on each side of the abdomen. Tomato hornworms have eight V-shaped marks on each side and the horn is straighter and blue-black.
