Plant mite fauna of Sistan-Baluchestan and Hormozgan Provinces.
An investigation on collection, identification, distributions and evaluating their economic importance of plant feeding mites done with regular sampling in different regions of Sistan-Baluchestan (southeastern) and Hormozgan (southern) provinces of Iran in 1994-97. Out of 107 plant species examined for mite harbouring, 51 different types of plants were recorded as mite hosts in both provinces. Two species of Tenuipalpus daneshvari (on aubergine), Brevipalpus phoenicis (on pawpaw and banana), Aceria mangiferae (on mango), Eriophyes cernuus [Aceria cernuus] (on jujube [Ziziphus mauritiana]), Acalitus salvadorae (on mustard [? Brassica juncea] trees), Brevipalpus lewisi (on pawpaw, custard apple and guava), were recorded as mite pests for the first time from Iran. Two species were also recorded from Astigmata mites. Outbreaks and damages caused by Tetranychus cinnabarinus on watermelon, Eutetranychus orientalis on jujube, Raoiella indica and Oligonychus afrasiaticus on date palm, Eotetranychus hirsti and Eriophyes ficus [Aceria ficus] on fig, Aculops lycopersici on tomato were observed as a primary pests on their respective host plants. Eight predatory mite families (Anystidae, Bdellidae, Chyletidae, Cunaxidae, Stigmaeidae, Erythraeidae, Trombidiidae and Tydeidae) collected from Prostigmata order. However, from Mesostigmata order, only three predatory families (Ameroseiidae, Lealapidae and Phytoseiidae) are identified so far. Abundance of Amblydromella dalfardica [Anthoseius dalfardica] on jujube, Amblyseius libanesi on sweet potato were more pronounced than the other species, while extensive distribution of two Anystidae mite species (Anystis baccarum and Anystis sp.) were recorded in most of the surveyed regions. Two species (Allothrombium sp. and Dinothrombium sp.) of Trombidiidae observed largest in size compared to the others in Sarbaz and Hajiabad region, respectively.
