The European corn borer is a major pest that causes corn to produce smaller ears, broken stalks, and drooped ears and sometimes even results in early death of the plant. What can be a use of biotechnology in providing an effective control against this pest?
|
|
application of more insecticides on the crops
|
|
|
introduction of an insecticidal gene from another organism into corn
|
|
|
introduction of wasps that can feed on this pest in the cornfields
|
|
|
cultivation of more corn seeds to combat the lower production

Explanation:
Detailed explanation-1: -Chopping the crop for silage or fodder will kill any borers in the stalks. If soil erosion is not a problem on your farm, clean plowing (leaving no crop residue on the soil surface) in the fall or before May 1 is effective in reducing the corn borer population overwintering in that field.
Detailed explanation-2: -Damage to corn is caused by the young larvae which chew leaves and tassels. Later they tunnel all parts of the stalks and ears, resulting in reduced plant vigor, broken stalks, poor ear development and dropped ears. Other crops are damaged primarily by the tunneling of the stalks, pods or stems by the larvae.
