Resp bhattacharya Mam as i am working on mites of agricultural importance i.e. spider mites and phytoseiid mites but yes they are very important as they are responsible for allergy and pest of stored grain thanks for reply
Due to following reasons, mites are gaining importance in present-day agriculture:
(1) More than 6,000 species of plant feeding (phytophagous) mites are known worldwide. The majority of plant feeding species belong to the obligate plant parasitic Eriophyoidea (e.g. gall mites, erinose mites, bud mites, rust mites) and Tetranychoidea (e.g. spider mites, false spider mites), while a number of species belong to other lineages (e.g. Eupodoidea, Tarsonemidae, and single oribatid mites).
(2) Plant feeding mites form an integral and important part of the natural ecosystem. Some species, especially eriophyoid mites, can be utilised for the biological control of weeds. Many plant feeding mites are of economic importance as pests of crop plants. Some species are already successfully utilized for the control of weeds, e.g. Aceria chondrillae (Canestrini) against skeleton weed, Chondrilla juncea L. (Asteraceae), in Australia and the USA, Aceria acroptiloni Shevtchenko & Kovalev against Russian knapweed, Acroptilon repens (L.) DC (Asteraceae), in Uzbekistan, and Aculus hyperici (Liro) against Hypericum perforatum L. (Clusiaceae).
