Photo 2. Mite infestations cause the leaves of taro to appear light green. Most damage is along the sides of the major veins; this can be seen from the upper surface, but most of the mites are on the under surface of the leaf.
Photo 3. Damage to leaves of cassava by Tetranychus mites. As with the symptom on taro (Photo 2) the damage is along the main vein.
Tetranychus species. The different species are difficult to tell apart; they need to be examined using a high power microscope. The two-spotted mite (Tetranychus urticae), also known as the red spider mite, is common in Pacific island countries, infesting over 200 species of plants. This fact sheet mostly concerns this species.
