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

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.
