Drugstore Beetle (Stegobium paniceum).The drugstore beetle, an Anobiid beetle, is somewhat similar to the cigarette beetle in habits. It has the reputation as a biscuit beetle or bread borer and develops on a wide variety of grain and food products, including spices, dried macaroni, drugs, and paper products. Internal symbionts aid in converting food to more nutritive materials. The sex pheromone is available for detection and monitoring. The insect can be found worldwide (Figure 21).
