The foliage of fruit orchards at three locations in southern Baja Cali
fornia Sur was sampled seasonally in 1990 to determine the presence an
d diversity of mites. A total of 9 families and 13 species of mites we
re collected. The Phytoseiidae family was the most diverse with three
species, followed by Tetranychidae and Tenuipalpidae with two species
each. The species Euseius hibisi (Chant) had the widest distribution,
finding it in three locations and on all fruit trees sampled.
