Khapra beetle
The Khapra beetle (''Trogoderma granarium''), also called cabinet beetle,〔http://www.mygetridofguide.com/get-rid-of-cabinet-beetles/〕 which originated in South Asia, is one of the world’s most destructive pests of grain products and seeds.〔(Stibick, J. (2007) ''New Pest Response Guidelines: Khapra Beetle'' ) APHIS–PPQ–Emergency and Domestic Programs, United States Department of Agriculture, Riverdale, Maryland, p. 1-1〕 It is considered one of the 100 worst invasive species in the world.〔
(University of Florida Food & Agricultural Services )〕 Infestations are difficult to control because of the insect's ability to survive without food for long periods, its preference for dry conditions and low-moisture food, and its resistance to many insecticides.〔 There is a federal quarantine restricting the importation of rice into the U.S,. from countries with known infestations of the beetle.〔

== Description of the insect ==
Adult beetles are brownish and 1.6–3 mm long. Immature larvae are up to 5 millimeters long and are covered in dense, reddish-brown hair. The eggs of the khapra beetle are cylindrical with one end more rounded and the other more pointed, about 0.7 mm long and 0.25 mm broad, weighing about 0.02 mg.〔Hadaway, A.B. (1956) "The biology of the dermestid beetles ''Trogoderma granarium Everts'' and ''Trogoderma versicolor (Creutz)''" ''Bulletin of Entomological Research'' 46(4): 781-796〕 The pointy end has a number of spine-like projections.〔 The eggs are initially a milky white but over several hours turn a pale yellowish color.〔
