The Lesser Grain Borer is a primary pest of grain in Western Australia meaning it can bore directly into a kernel where it will consume the insides reducing it to a hollow husk where it will reside and complete its larval life. This stored product pest is probably the most serious pest of stored products in WA. It is primarily a pest of stored wheat and corn but it can also infest tobacco, nuts, birdseed, biscuits, and cocoa beans as well as spices, rodent baits, and even dried meats.
