Corn borer Ostrinia nubilalis

The European corn borer is the most important pest in maize and causes enormous problems to more and more farmers.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. The second generation in August and September is a greater threat to late-planted corn. Borers of this generation tunnel in ears, ear shanks and stalks. Stalk breakage may be serious. Borer entrance holes in corn plants also provide a site for stalk rot pathogens to enter the plant.
The larvae are dirty white, often having a pinkish tinge. The skin is smooth and free of hairs. There are numerous dark spots scattered over the sides and top of the body. The head is dark brown to black. The moths are yellowish buff to light tan in color. They have several dark zigzag marks across the wings, and their wing spread is 2cm to 2.5cm. They are active during late evening and at night.
