This series of two-page briefs highlights some of the new technologies and processes available, in order to inspire practitioners and policy-makers to put them to use. This one describes how simple traps made from small plastic jerrycans and baited with pheromones give farmers a valuable early warning system against the legume podborer. The podborer moth's caterpillars cause devastating losses in cowpea. But, catching a certain number of adult moths 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.
