Detailed explanation-1: -How does European corn borer damage corn? Damage to corn occurs as larvae feed on the leaves and bore into corn stalks and ear shanks. European corn borer tunneling (Figure 1) results in reduced yield potential, broken stalks, and dropped ears.
Detailed explanation-2: -European corn borer is an economic pest on a wide variety of field and vegetable crops including corn (field, sweet, & popcorn), snap beans, peppers, potatoes, and tomatoes. Damage is primarily due to borer tunneling in leaf midribs and the stalk.
Detailed explanation-3: -After boring into the stalk, the larvae usually feed inside the plant until they reach maturity and pupate. Stalk entry and tunneling by corn borer may predispose the plant to pathogens which may lead to stalk rots later in the season.
Detailed explanation-4: -If the larvae establishes within a plant it may cause several types of damage. The most severe damage is stalk breakage prior to harvest (Figure 7). Another type of damage is ear drop where cobs fall to the ground. The final type of damage may be the least obvious but can cause significant yield loss.
