ABSTRACT

The storage mites form the largest group of class called Arachnids. Arachnids, being small in size, are ecologically important in most terrestrial environments. Arachnids were the first arthropods to enter terrestrial habitats as evident from the oldest fossil of Silurian scorpions by the end of the Paleozoic. The mites are important to human life as they invade grain and grain products and other stored products. The mites cause direct and indirect damage to stored grains and their products by raising their moisture contents and generating sufficient heat for the growth of infectious bacteria and fungi. Mite-infested grains undergo a series of changes in their chemical composition affecting the germination capacity; flour prepared from contaminated grains is more acidic and of fusty smell and bitter taste. There are no any specific management practices of mites under storage condition, but the following precaution must be taken to prevent the growth and development of mites.
