Citrus rust mite
The citrus rust mite (Phyllocoptruta oleivora)
The yellow tiny citrus rust mite attacks mainly the fruit. Its feeding causes the rind of the fruit to turn silvery, reddish brown, or blackish. One result of mite
damage is small fruit, which deteriorates rapidly. This damage lowers the market value of the fruit. Heavy populations of the rust mite
cause bronzing of leaves and green twigs, and general loss of vitality of the whole tree. Warm and humid conditions favour the development of rust mite.
