The Khapra Beetle(Trogoderma granarium) is one of the world’s most destructive pests of stored grain products and seeds. Its feeding damage often spoils 30 percent of the product; up to 70 percent damage has been reported. The obvious signs of a khapra beetle infestation are the larvae and cast skins. However, the larvae look very similar to those of other relatively unimportant Trogoderma spe-cies, as well as some carpet beetles. Larvae and adults are best identified by microscopic examination. USDA-APHIS inspects cargo ships and cargo from khapra beetle infestedFile Size: 1MB. The khapra beetle (Trogoderma granarium) does outsize damage to stored grains and is a top target as a potential invasive species at ports and border crossings. Researchers in Canada have found the threshold temperature that will kill the beetle at all life stages, even diapause. Biology. Adult khapra beetles are not long lived; mated females last up to 5 days while unmated females can last 30 days and males from one week to 12 days. Mating occurs 5 days after emerging from pupation and egg laying occurs right after mating. Complete development from egg to adult depends on temperature and can last anywhere from 26 to days.
THE khapra beetle, Trogoderma granarium Everts, is a dermestid pest of stored grain from India, now established in British malt stores. Ecological work in these stores and laboratory experiments Cited by: The classic telltale sign of a khapra beetle infestation is the presence of cast skins and larvae. The larvae are yellowish to golden brown (see picture below). They are clothed with fine setae, and there are tufts of barbed setae on each side of the terminal abdominal segments. Use New Pest Response Guidelines: Khapra Beetle as a guide when designing a program to detect, monitor, control, contain, or eradicate an infestation of this pest. If khapra beetle is detected in the United States, PPQ personnel will produce a site‐specific action plan based on the Guidelines. State agriculture. Khapra beetle is considered to be one of the world's most destructive pests of stored food products. It is a voracious feeder of grain products, can tolerate colder climates and is capable of hiding in cracks and staying in a diapausal state for up to six years.
Biology of Khapra Beetles: Discovered in the US in , Known to infest warehouses and food processing plants and can infest any structure and prospers in pantries, closets, garages, laundry rooms, and basements where wheat, grain, cereal, barley and rice are stored. Introduction (Back to Top) The khapra beetle, Trogoderma granarium Everts, is one of the world's most feared stored-product pests. In fact, it has been described as one of the worst invasive species worldwide (Lowe et al. ). khapra beetle larger grain borer lesser grain borer maize weevil mediterranean flour moth red / confused flour beetle rice moth rice weevil rusty grain beetle saw-toothed grain beetle vetch bruchid warehouse pirate bug warehouse, or tobacco moth yellow/dark meal worm beetle . The khapra beetle is sometimes brought to temperate regions but as it requires a temperature of at least 24° C for breeding there is little risk of it becoming established.
