Description: The female individuals of A. sheldoni are small: 0,17 to 0,18 millimeters. They are vermiform and light yellow. The males measure 0,13 millimeters.

Citrus bud mites hide inside buds, which they damage or destroy. Their life cycle lasts about fifteen days; citrus bud mites thrive in high relative humidity and temperatures ranging from 25 to 27 ºC.

The whitish, spherical eggs are laid inside the buds. Females can lay about 50 eggs. The nymphs are very similar to adults; they are wedge-shaped and have only two pairs of legs. They are smaller and whitish.

General damage: Citrus bud mites affect production because they delay and reduce plant growth. Buds, flowers and fruits are deformed. A. sheldoni can be found in all the citrus-producing areas of the country, as well as in lemon, grapefruit and orange trees. Leaves have irregular shapes and fall prematurely.
