Bryobia rubrioculos?

This is the brown fruit spider it attacks fruits. I need pictures of it and how to protect my plants (orchard of sour cherry).

About protection, check below. Hope that helps-



Mites

Different mite species occur on stone fruit trees. Most important are Tetranychidae, such

as the brown mite Bryobia rubrioculus (Scheuten) and the European red mite Panonychus

ulmi (Koch) as well as Eriophyidae, such as the plum rust mite Aculus fockeui (Nalepa

and Trouessart), and the peach silver mite A. cornutus (Banks).

Significance

Highly variable, according to the species. Panonychus ulmi is the most important mite

and one of the main pests in stone fruit orchards.

Damage

Mites injure plants directly by feeding on the leaves. Withdrawal of lymph and chlorophyll

initially causes discolouration in infested leaf areas. Later, leaves may turn bronze

and, in some cases, they may be rolled or distorted. Early leaf fall may result. Mites in

the family Eriophyidae may transmit viruses (Oldfield 1970).

Hosts

Most species are polyphagous on deciduous fruit trees.

Geographical distribution

Brown and European red mites are

a limited distribution (Jeppson et al.

cosmopolitan (CIE 1972, 1984). Other species have

1975).

Biology

Nearly all mites feeding on stone fruits are polyvoltine. Some of them, such as Bryobia

rubrioculus or Panonychus ulmi, overwinter as red and onion-shaped eggs on budwood,

whereas Eriophyidae hibernate as adult females in bark crevices or under loose bud

scales.

Treatment

Budwood infested by mites should be dipped in acaricides, preferably ovicides, such as

clofentezine, or larvo-adulticides, such as dicofol or fenbutatin oxide.
