European Corn Borer ecology (Ostrinia nubilalis): This moth caterpillar devastates some crops, particularly maize. There is at least one generation per year, perhaps two if the temperature is warm enough. The adult moth lays eggs on the leaves of the plant. When the larvae hatch they will begin to strip the leaves and soon after will bore into the stem causing disruption to the plant’s water and nutrient supply.
Practical management includes the use of insecticides when the larvae are foraging on the leaves. Once the larvae is inside the plant the pest is very difficult to manage.
If you have seen Corn Borer please register your sighting.
To see if there are corn borer in your crops you can use pheromone or light traps. Timing is the most important aspect for Corn Borer treatment : If the larvae start to bore there is no effective treatment.
