Akua Konadu Antwi-Agyakwa wants to find a non-chemical way to control insects that attack cowpeas, the most commonly used legume food crop in Ghana. She says cowpeas are an economically important and versatile crop, since nearly every part of the plant is consumed by both humans and animals. “Unfortunately, however, cowpeas are attacked by a myriad of pests, from the seedling stage through to storage. If not controlled, one or more of these insect species can cause the total loss of the plants or beans.”
