![]() ![]() Report the detection immediately to the Department of Agriculture, Fisheries and Forestry. collect a sample, if possible to do so without disturbing the insects.do not disturb the insects (this may be as simple as closing the doors on a shipping container or sealing a silo).If you suspect you may have found khapra beetle: containers used for storing or moving produce, including in cracks and wall linings of storage containers.stored produce including grain, rice, cotton seed, powdered milk and nuts.On receipt of imported products from countries where khapra beetle is established, check: Look for khapra beetles in the corners and bottom of bags containing grain or cereal products (for example flour, pasta, rice, oats, coriander seeds) and also check cracks and crevices of your pantry. Khapra beetles and larvae are tiny and generally hard to see. Where to look for khapra beetleĪs khapra beetle is a stored grain pest it will only be found in stored products (Figure 4) and around places where stored products are kept or transported. Khapra beetle can cause up to 75 per cent grain loss due to direct feeding and also causes contamination of stored grain with cast skins and beetles, that can pose a health risk.ĭue to its ability to survive without food for years and limited effective treatment options for larvae, management is extremely challenging once established. Khapra beetle is listed as number two on Australia’s National Priority Plant Pests list and if it becomes established, could have a devastating impact on Victoria’s grain, dried fruit and nut industries through lost trade. The beetle can also hitchhike in shipping containers, packaging or other household furnishings imported from countries where khapra beetle is found. It is spread through the movement of infested stored grain and dried food products (for example flour, breakfast cereals, pasta, coriander seed), or contaminated seed, machinery and packaging. Khapra beetle is native to India but has spread and can be found in Middle East, Asia, Africa and Europe. rat and mouse baits, and snail pellets.coriander seed, bread, dried coconuts, cornmeal, crackers, white and wholemeal wheat flour, pasta, dry baby food, pearl barley and wheat germ.Other commodities that often serve as hosts include: rolled and ground barley, ground corn, ground dog food, rolled oats, ground rice, cracked and ground wheat bran.soybeans, lentils, dry peas, grain sorghums, cowpea and corn.Their food preference is grain and cereal products, including wheat, barley, oats, rye, maize, rice, flour, malt and noodles. Khapra beetle is a pest of stored foods and can feed on most dried plant or animal material. However, larvae can survive in a dormant state for many years in unfavourable conditions. The larval development stage may be as short as 30 days. Larvae moult four or more times, resulting in numerous cast larval skins. This is the major feeding stage and therefore the most damaging. Adults are not commonly encountered because their offspring eat their bodies for protein.Įggs hatch within 5 to 7 days into larvae. Adult beetles live between 12 and 25 days and cannot fly. Adult females begin laying eggs shortly after mating, in or near host material and generally lay 50 to 100 eggs during their lifetime. Life cycleĪdult male and female beetles mate immediately after emergence. Expert diagnostics is required to identify khapra beetle. Khapra beetle may be confused with other Trogoderma species in Australia (e.g. shed cast skins from the growing larvae.are initially pale yellow and become golden-brown when they grow.are very hairy with a 'brush' of long spiky hairs like a tail.have a smooth, oval-shaped body, covered in fine hairs.Khapra beetle is currently absent from Australia and would severely impact our international trade if it became established here. It is very resilient and can survive in stored food, packaging and transport facilities in very low numbers under difficult conditions. Khapra beetle ( Trogoderma granarium) is a serious exotic pest of stored grain, cereals and dry food stuffs.
