Citrus broad mite

Identification tip:  Broad mites feeding on succulent shoots cause expanding young leaves to curl. This leaf cupping and distortion can resemble injury caused by glyphosate (Roundup) herbicide application.

Identification tip: Broad mites prefer to feed on young fruit, up to about 1 inch in diameter, that are growing sheltered within the inner canopy. When fruit grow and expand, this earlier injury becomes apparent as discolored, scarred or cracked tissue on the rind surface. Often the inner-facing side of fruit is scarred but the outward-facing side is undamaged.

Identification tip: Broad mites often feed and lay eggs in depressions on fruit. Adults and nymphs are yellowish with a white stripe on the female's  back. Eggs are dimpled, translucent, and covered in white speckles. Broad mites are smaller than spider mites. To see broad mites, you need a quality hand lens or preferably a binocular dissecting microscope.

Citrus rust mite

Identification tip: Rust mite feeding causes blackish or gray discoloration on green (unripe) oranges. On lemons, rind damage is pale or silverish and this pest is called silver mite.

Identification tip: On ripe oranges, citrus rust mite feeding causes brownish scarring (russeting) of the rind.

 Citrus rust mite adults

Identification tip: These tiny mites are wedge shaped and pale. Eriophyids have only four legs, all attached at their front (widest) end.

Citrus flat mite Citrus bud mite

Identification tip: This mite is variably colored, often pinkish or salmon, and is much smaller than citrus red mite. It is a secondary invader that occurs where rinds were injured by leafhoppers, thrips, or wind. Flat mite occasionally is a pest when its feeding causes these otherwise damaged spots to develop into more obvious scars on rinds.

citrus bud mite damage
Citrus bud mite damage
Identification tip: Feeding within lemon buds on new succulent growth distorts flower buds (shown here), fruit, shoot tips, and leaves. Feeding occurs in buds during the fall and winter causing damage to spring bloom and the resulting fruit. Bud mite is usually a pest only on coastal lemons.

Citrus bud mite damage
Citrus bud mite damage
Identification tip: Citrus bud mite feeding can distort young lemons, although fruit is usually not this severely misshapen. This injury was caused several months earlier while the tiny eriophyid mites were feeding inside the flower bud.
