Texas citrus mite

Eutetranychus banksi

Texas citrus mite is a sporadic pest of citrus in the inland valleys of California. Adult mites are tan-to-brownish green with dark green to black spots on the upper side of the body. Males are more slender than females and have much longer legs. Females have a more round-to-oval shape and are somewhat flatter than citrus red or Yuma spider mite. All stages of mites, including eggs, tend to be located along the midrib and lateral veins. Eggs are somewhat flat and disklike, are not a uniform color, and range from yellow when laid to a reddish brown before hatching.
In the San Joaquin Valley, Texas citrus mite can sometimes be found in low populations in spring, especially following insecticides such as formetanate hydrochloride (Carzol) or methidathion (Supracide) that disrupt biological control. Populations of this mite decrease in summer but increase from September through December. When weather becomes cold and wet, which usually equates to the first overnight period of dense Valley fog, populations decrease again.
