Factsheet of the month: December – Management of white stem borer of coffee

The white stem borer, also known as Seto Gavaro, is a major pest of coffee in Nepal. In fact, the government and industry hold the pest largely responsible for the drop in production between mid-2012 and mid-2013. Coffee is a major cash crop in Nepal so it is important that farmers do not lose yield to pests such as the white stem borer.
