The earth is surrounded by some 900 thousand different kinds of living insects. About 40% of all known insect species are beetles.
It’s tiny. It’s scary. It likes to travel.
Khapra beetle is one of the world’s most destructive pests of grain products and seeds. These beetles are also called cabinet beetle. Infestations are difficult to control because of the insect's ability to survive without food for a long period. They are brownish and 1.6-1.3mm long and covered the dense reddish-brown hair. The eggs of the khapra beetle are cylindrical with one end more rounded. This insect is well established in the hot, dry climates of Africa, the Mediterranean, and South East Asia. They mostly damage cereal products particularly wheat, barley,
oats, maize, rice, flour, malt, and noodles. They can feed on products with as little as 2% moisture content and can develop on animal matter such as dead mice, dried blood, and dried insects.
The Khapra beetle is labeled as a ‘dirty feeder’ because it damages more grain than it consumes, and because it contaminates grain with body parts and hairs. These contaminants may cause gastrointestinal irritation in adults and especially harm the infants. Khapra beetles are immune to insecticides and fumigants.
The larvae, if left untreated, can reduce grain weight by as much as 70% and unfavorably change the chemical composition of stored rice or other grain. Human ingestion of foods containing the Khapra Bug can require hospitalization due to extreme digestive problems.
According to the USDA Animal and Plant Health Inspection Service, concluded that Khapra beetle is a big nuisance. The eradication efforts of these beetles are of great cost to the American Tax payers.
California implemented extensive eradication measures following Khapra beetle infestation discovered there in 1953. The efforts were deemed successful, but at a cost of approximately $11 million. If we estimate it in today’s world it will cost up to $90 million.
USDA even banned the import of rice from countries where Khapra beetles are found at large. These restrictions were due to the increasing number of detection of the infested shipments of rice from those countries
20% loss in weight of seeds is observed within a storage period of 6 months under natural condition. In India average damage level ranges from 6-33% of grain in a single storage season with maximum damage of 73%. Loss of weight in wheat ranges from 2.2-5.5%. It is reported that 15% infestation level caused 26% loss in weight and 24% in viability of wheat grains in few month of storage.
The general used method for the problem of the infestation is fumigation. Methyl bromide or phosphine is usually the chemical of choice. Because of Khapra beetle’s habit of hiding in every conceivable crack and crevices, the entire storage facility and its contents must be fumigated.
Fumigation is not very effective and also is highly toxic, hazardous and it deteriorates the quality of food which can cause many health hazards to humans.
C Tech Corporation caters with its niche product Termirepel¢ which is non-toxic, non-hazardous and environmental friendly and repels 500 species of insects. Its life span is 25-40 years depending on the end application. It can be easily incorporated in agricultural tubing and hosing, drip irrigation, agricultural films, tarps, mulches. As it does not leach out from the application it does not contaminate ground water and soil.
Termirepel¢ can also be used in the silage bags to store grain as Khapra beetles infest stored grain and in tarps to cover the store grain.
