The harmful characteristics of corn stickworm
The corn stickworm gluttonizes corn leaves with larvae. When it occurs seriously, the leaves are eaten in the short term, resulting in reduced yields and even no harvest. Symptoms of damage are mainly larvae that eat the leaves. 1 to 2 instar larvae feed on the leaves to cause holes, and larvae above 3rd instar damage the leaves and show irregular nicks. When gluttonous, they can eat the leaves. In the great event, the leaves of the corn were eaten, leaving only the leaves and veins, resulting in serious reductions in production and even in nowhere. When a field of corn is eaten, the larvae often move into groups and move into another field. Therefore, they are also known as “Pestsâ€. Generally, the terrain is low, the height of corn plants is uneven, and the weedy fields are heavy.
