Damage
Each larva can consume over 400 square centimetres of foliage during its development. They feed above ground until about the fourth instar. After that they do considerable damage to crops by severing young plants at ground level. In the midwestern USA the black cutworm is considered to be a serious pest of corn which is very susceptible at the one-leaf stage but by the 4 or 5-leaf stage it is relatively unaffected. Damage to the underground parts of plants can also be harmful. Other crops where serious damage occurs include cotton, maize, tobacco, sunflower, tomatoes, sugar beet and potato.

Famous quotes containing the word damage:
“I came to explore the wreck.
The words are purposes.
The words are maps.
I came to see the damage that was done
and the treasures that prevail.”
—Adrienne Rich (b. 1929)
“Instead of asking—”How much damage will the work in question bring about?” why not ask—”How much good? How much joy?””
—Henry Miller (1891–1980)
“For most Northerners, Texas is the home of real men. The cowboys, the rednecks, the outspoken self-made right-wing millionaires strike us as either the best or worst examples of American manliness.... The ideal is not an illusion nor is it contemptible, no matter what damage it may have done. Many people who scorn it in conversation want to submit to it in bed. Those who believe machismo reeks of violence alone choose to forget it once stood for honor as well.”
—Edmund White (b. 1940)
