Simple traps made from small plastic jerry-cans and baited with pheromones give farmers a valuable early warning system against the legume podborer. This insect’s caterpillars cause devastating losses in cowpea. But, catching a certain number of adult pod borers in traps lets farmers know that caterpillars will soon appear in their fields, and that they should spray their crop in the next few days. The system was designed and tested in tandem with farmers and NGOs in Benin and Ghana, and there is demand for traps and lures from other farmers who have heard about the technique. The system has potential for many more areas where the podborer threatens cowpea.
