The mung bean has been grown in India since prehistoric times. It is popularly cultivated in Southeast Asia, Africa, South America and Australia. Earlier it was flourished in the United States as early as 1835 as the Chickasaw pea. Mungbean (Vigna radiata (L.) Wilczek), also famous as green gram, is one of the most important pulse crops grown in India. Mungbean has been used for variety of purposes. The major product obtained from the mung bean plant is its seed. Mung bean is utilised in wide range of food products, both as a whole seed and in processed form1. Being used in dishes like dal, curries, soup, sweets and snacks as well as rich in the thiamine, niacin and ascorbic acid content during its sprouting stage, thus mungbean are rapidly becoming popular in vegetarian diets. It is also rich in food values due to its high and easily digestible protein. Mungbean proves to be an excellent complement to rice for balanced human nutrition as per amino acid analysis. Mungbean is grown mostly during rainy season, however development of short duration and disease resistant varieties led its cultivation during spring season in almost all parts of country, during summer after harvest of potato and wheat in north India and during winter (rice fallows) in peninsular India. Under Gangetic basin of West Bengal, it is mostly grown during pre-kharif season (Mar- Apr to May- June). Mungbean is affected by various insect and non-insect pests, among which the yellow mite, Polyphagotarsonemus latus (Banks) plays an important role amounting huge crop loss. The yellow mite, Polyphagotarsonemous latus (Banks) (Acari: Tarsonemidae), which is also known as broad mite is enormously polyphagous, and showed its presence on more than 60 plant families. Yellow mites are very small in size (body length between 100 and 200 microns) as a result they got overlooked until they cause serious damage occurring rapidly which appears on the leaves. Farmers who are not aware with the damaging symptoms might confuse them with variety of things like signs of a virus, phytotoxicity from a pesticidal product, or a nutrient related disorder2. The mites are usually noticed on the upper part of the plant, feeding on the apical shoots and the abaxial side of young leaves. Yellow mites are basically cell feeders, having styliform simple chelicerae that are only slightly reversible3. Being a polyphagous mite pest the yellow mite used to feed on wide variety of crops causing different symptoms in different hosts and plant organs. Usually, the common symptom is the retarded plant growth4,5. In general, the immature apical leaves are seriously damaged, seem distorted, more rigid, and with curled down edges. The fruits, if any appear, may be cracked and sometimes reticulated6,7,2,5.
