Drugstore beetle, also known as the biscuit beetle (Ward and Humphries, 1977) or bread beetle (Ward, 1981), Stegobium paniceum (Linnaeus, 1758) (Coleoptera: Anobiidae) is distributed throughout the temperate and tropic regions of the world (Abdelghany et al., 2010). It has a complete life cycle (holometabolous: egg, larva, pupa, and adult). Adults are nondescript, brown beetles that are oval in shape and measure a few millimeters in length, while larvae are grub-form in appearance. This insect completes its lifecycle in approximately 20 weeks depending on environmental conditions. Historically, this insect has been considered a pest of stored products as it ‘contaminates’ various materials of human and animal use as food and feed respectively; however, more recent interest has been in the potential development of this insect for mass-production and use as a source of protein for human consumption (Kok, 1983).
