Controlling insect damage to cereal crops to keep them marketable does not stop with the harvest. It continues in storage, where grain is vulnerable to pests such as the khapra beetle (Trogoderma granarium). The small brown beetle, measuring just 2 millimeters in length, can cause up to 70 percent spoilage in stored cereals that it infests. (Image credit: Pest and Diseases Image Library, Bugwood.org)
