Materials and Methods
Between 1990 and 2003 a mite survey was made on ornamental trees and shrubs of
streets, squares, parks, botanical gardens, private gardens, and green areas of housing es-
tates in all districts of Budapest city.
Plant samples from 307 woody species were collected in plastic bags between Jan-
uary and late November. All the plant material was examined with binocular stereomicro-
scope (upper and lower surfaces of the leaves, petioles, buds, bark, flowers, galls, etc.).
The mites found on the plant samples were put directly into lactic acid or AGA solution (al-
cohol, glycerol, acetic acid, sorbitol). After clearing the specimens in lactic acid (for 2–4
weeks in a room temperature to the desired extent), they were placed into Keifers’s medium
“2” (for 0,5–2 hours) following the Keifers’s mounting method for eriophyoid mites (Keifer,
1952). Finally, cleaned and stained mites were then placed into Keifers’s medium “3“. The
F-medium with sorbitol (Keifer, 1975) was used alternatively for mounting the specimens.
The slide preparations were dried (for 2–4 weeks) in incubator at 32 °C, and then sealed
with commercial nail varnish (Upton, 1991). Specimens were examined with a phase con-
trast microscope. The generic classification was made according to Amrine et al. (2003) and
further updating. The terminology and setal notation used in the morphological descriptions
are those of Lindquist (1996). The number of measured specimens (n) is given in parenthe-
ses in the body length. All measurements of mites were made according to Amrine and
Manson (1996) and are given in micrometers. Measurements and means are rounded off the
nearest integer. All measurements, unless specified, are length. Because some measure-
ments of holotypes could not be made, due to the position of the mounted mite, means are
reported, with range in parentheses.
Holotypes and paratypes are deposited in the Hungarian Natural History Museum,
Budapest, Hungary.
