Natural Enemy and Breeding May Suppress Aphid Pest
Corn leaf aphids, besides reducing sweet corn yields, transmit several diseases–including maize dwarf mosaic and barley yellow dwarf virus. Lately, insecticides haven’t always provided good control. But biological control offers promise. Researchers are assessing the aphid’s natural enemies and have found that sweet corn lines resistant to European corn borer also seem to possess resistance to corn leaf aphids.
