Abstract :

Diversity and abundance of plant feeding mites on green parts and soil of tea plant gardens were investigated in 15 localities during period of 2008-2009 in Eastern part of Gilan Provinces of Iran. Mites were collected from tea leaves and stems by shaking on white tray and from depth of 5 centimeters of soil with in Tullgren apparatus individually for each localities. 36 species from 33 genera and 31 families included in four suborders, Astigmata, Cryptostigmata, Prostigmata and Mesostigmata were identified. Higher and lower abundance of injurious mite were recorded for Brevipalpus obovatus and Tyrophagus putrescentiae, Tuckerella hypoterra, Tetranychus urticae respectively whereas, maximum predacious mites were recorded in Bdellidae, Phytoseiidae and 15 Oribatidae species of Two oribatid mites species, Pergalumna sp, Eupelops sp. with highest densities and Metabelba sp, along with two unidentified oribatid mites belong to Phthiracaridae and Euphthiracaridae families recorded with number of  mite specimens in surveyed localities. Oribatid mite constituted 41% of mite species diversities with total 59% of mite collections. Four oribatid mite families picked up from leaves and stem of tea plants only. Out of mite collected, 81% are new record for mite fauna of tea garden in Iran. Mite identification are as follows: Acaridae(Tyrophagus putrescentiae), Ameroseiidae (Ameroseius sp.), Digamasellidae (Dendrolaelaps sp.), Ologamasidae  )Gamaseiphis sp.) Pachylaelapidae (Pachyseius sp.), Parasitidae (Vulgrogamasussp.), Phytoseiidae)Amblyseius largoensis, Iphiseius sp., Typhlodromips caspiansis) Achipteriidae (Parachipteria sp.) Cepheidae (Conoppia sp.) Camisiidae) Camisia sp.), Nothridae (not identified) Ceratozetidae (Trichoribates sp.), Humerobatidae (Humerobates sp.), Damaeidae (Metabelba sp.), Galumnidae (Pergalumna sp.), Liacaridae (Liacarus sp.), Oribatulidae (not identified), Scheloribatidae (Scheloribates sp.), Oppiidae (Oppia sp.), Phenopelopidae (Eupelops sp.), Phthiracaridae and Euphthiracaridae (not identified), Anystidae (Chaussieria warrengense, Chaussieria sp.), Bdellidae (Bdella sp., Cyta sp.), Camerobidiidae (Tycherobius sp.), Erythraeidae (Leptus sp.), Eupodidae (Cocceupodes sp.), Tenuipalpidae (Brevipalpus obovatus), Tetranychidae (Tetranychus urticae), Microtrombidiidae (Microtrombidinae), Trombidiidae (Dinothrombium sp.), Tuckerellidae (Tuckerella hypoterra).
