Mite Feeding Damage
|
|
Mites commonly occur on all types of plants. They are not insects, rather in the class Arachnida, having 8 legs instead of 6. Mites are typically microscopically small, measuring less than 0.5 mm in length.
On coffee, symptoms of mite feeding damage may be seen as stippling and bronzing to a slight-silvering color of the upper portion of the leaves (spider and false-spider mites, tea mites, etc). There might also be a webbing over the leaves as a result of spider mites. Broad mites can cause, especially younger leaves, to become cupped, curled, and leathery in appearance. The leaf shape may be distorted and smaller than normal. Mite infestation can cause a reduction |
in leaf surface area and chlorophyll and premature leaf drop, thereby, reducing photosynthesis by the tree and potentially reducing yield and quality.
