Tetranychus cinnabarinus (Boisduval, 1867) - (carmine spider mite or tropical red spider mite)
is highly polyphagous and widespread in warmer regions and greenhouses around the world. The mite feeds mainly on the underside of the leaves, causing chlorosis, leaf curling and premature leaf drop. In field crops, the mite is mainly controlled by acaricides, but the development of pesticide resistance has been a problem. The females are oval, around 0.5 mm long and brownish-red with dark spots. The males are slightly smaller yellowish-green with a black spot on both side of the body. The complete life cycle from egg, through 2 nymphal stages, protonymph and deutonymph, to mature adult last about 1-3 weeks. Per year, 20 and more generations may be completed. The species is very similar to Tetranychus urticae. In general it can be distinguished by the colour of the summer females which is red (rather than yellowish-green).
