Abstract
A study was undertaken with the objective of recording the diversity of mites
associated with selected plants species in Lalbagh Botanical Garden, Bangalore and some
places around Bangalore during 2010-2011. Forty seven species of plants consisting of
trees, shrubs and herbs, common to India and Syria were considered for the study. The
mites were extracted from these plant species, microslides of the specimens were
prepared and the taxonomic identification of the associated mite species was carried out.
The results revealed the presence of 71 species of mites under 38 genera and 17 families.
Phytoseiidae was represented by the maximum number of species/genera (20/7),
followed by Tenuipalpidae (9/4), Tetranychidae (8/5), Iolinidae (6/2), Eriophyidae (4/3),
Stigmaeidae (4/2), Tydeidae (4/3), Cunaxidae (4/2), Ascidae (3/1) and Tarsonemidae
(2/2). The mite families, Diptilomiopidae, Tuckerellidae, Camerobiidae, Eupalopsellidae,
Raphignathidae, Bdellidae and Erythraeidae were represented by single species each. Of
the 71 species of mites collected, 61 species are already known, which includes 6
recorded for the first time in India; four species are assigned nearer to already known
species; viz., Brevipalpus sp. nr. euphorbiae (Tenuipalpidae), Euseius sp. nr. prasadi
(Phytoseiidae), Pronematus sp. nr. fleschneri (Iolinidae) and Cunaxa sp. nr. womersleyi
(Cunaxidae); six species are not in conformity with the descriptions of the already known
species, hence appear to be new to science. These are; two species under the genus
Tydeus (Tydeidae); one species each under genera Lorryia, Paralorryia (Tydeidae), Asca
(Ascidae) and Exothorthis (Eupalopsellidae). Forty seven plant species from which the
mites were collected belonged to 27 botanical families, of which plant species Cupressus
macrocarpa, C. sempervirens, C. arizonica, C. benthamii, Thuja compacta, T. orientalis
(Cupressaceae); Araucaria cookii, A. cunninghamii (Araucariaceae) recorded the
maximum diversity of mite species.
