Cotton, Gossypium hirsutum L., is an important field crop which produces natural fibre. Cotton is produced around the world especially in Iran, regardless of the fact that every year many pests attack cotton plants which bring about significant damages. Spider mites are well-known significant pests of different crop species, particularly in cotton...

... sharply posteriorly angled. Tetranychus turkestani has a close resemblance to T. urticae aspect of taxonomical. However, there was a difference between them in their aedeagus male. As in T. urticae ratio of knob length to back ward length of aedeagus was one-sixth, while in T. turkestani was one-third C.) (Tuttle & Baker 1968, Jepson et al. 1975) (Fig. 2). Empodium on tarsus of first leg is claw like with hair back spine like. The length of this hair is two-third in length of abdominal empodium hair. Spine empodium hair on pretarsi of second leg is two-third and bigger than spine of empodium hair in third and fourth leg pretarsi (Fig. ...

... Occurrence of other phytophagous mites has also been reported on brinjal which includes T. ludeni (Reddy et al., 1987a, b), T. macfarnalei (Meyer, 1974), T. neocaledonicus (Pande and Yadav, 1976), Aceria lycopersici and Aculops lycopersici (Dhooria, 2003). Forghani and Honarparvar (2012) reported occurrence of Tetranychus turkestani, Tetranychus urticae and Schizotetranychus sp. as 52.27, 40.80 and 6.91% of the spider mite populations, respectively, in cotton. ...
... In geranium, Opit et al. (2005) recorded leaf browning, leaf distortion, necrotic leaf margin and bronzing in mite infested plants. Forghani and Honarparvar (2012) observed that T. cinnabarinus, T. turkestani and T. ludeni infestation on cotton caused a rapid leaf fall which led to plant death. Sharma and Pati (2012) reported white and silvery spots on Withania leaves after feeding on the lower side of the leaves. ...
Tetranychus urticae Koch, two-spotted spider mite, is one of the most serious agricultural pests of brinjal worldwide causing qualitative and quantitative damage, and thus, leading to huge economic losses. T. urticae feeds on cell sap on the underside of the leaf, while the upper surface of the leaf develops whitish or yellowish stippling characteristics, which may join and become brownish as mite feeding continues. Indirect effects of feeding may include decrease in photosynthesis and transpiration. For developing IPM strategies, a clear understanding of population dynamics, biology, nature of damage and effect of abiotic factors is essential. Hence, effort has been made to present and review the available literature on these aspects in various crops under different sub-heads.
... At least 23 species of mites have been reported to attack cotton crop worldwide (Leigh, 1985). Forghani and Honarparvar (2012) found three mites of family Tetranychidae namely Tetranychus turkestani (Ugarov et Nikolskii), T. urticae Koch and Schizotetranychus species on cotton in Iran. However, the published information on diversity and mite incidence on Bt-cotton is scarce and no studies have been carried out in Punjab State. ...
This study was conducted in 2018 to determine the mite species in walnut orchards in Samsun Province, Turkey. A total of 101 samples were collected from 68 orchards in 17 districts. Of the samples, 78% had mites and they belonged to 15 families. However, only nymphs of Iolinidae and Oribatulidae were found and they could not be further identified. Therefore, in total, thirty eight species belonging to 13 families were identified. The species were Lepidoglyphus destructor (Schrank) (Glycyphagidae); Aceria erinea (Nalepa), Aceria tristriata (Nalepa), Anthocoptes striatus Ponomareva (Eriophyidae); Brevipalpus californicus (Banks), Brevipalpus obovatus Donnadieu (Tenuipalpidae); Amphitetranychus viennensis Zacher, Tetranychus turkestani (Ugarov & Nikolski) (Tetranychidae); Anystis baccarum Linnaeus (Anystidae); Cheletomimus berlesei (Oudemans), Cheletogenes ornatus Canestrini & Fanzago (Cheyletidae); Cunaxa sp. nr. setirostris (Hermann), Cunaxoides sp. nr. biscutum (Nesbitt) (Cunaxidae); Agistemus duzgunesae Koç, Çobanoğlu & Madanlar, Zetzellia mali (Ewing), Zetzellia sp. (Stigmaeidae); Triophtydeus triophthalmus (Oudemans) (Triophtydeidae); Lorryia mali (Oudemans), Lorryia superba Oudemans, Brachytydeus obnoxia Kuznetzov & Zapletina, Lorryia woolleyi (Baker), Tydeus kochi Oudemans, Tydeus meshkinensis André, Ueckermann & Rahmani, Tydeus cf. shabestariensis Akbari, Haddad & Kaźmierski, Tydeus spathulatus (Oudemans) (Tydeidae); Euseius finlandicus (Oudemans), Euseius gallicus Kreiter & Tixier, Euseius stipulatus (Athias-Henriot), Kampimodromus aberrans (Oudemans), Neoseiulella tiliarum Oudemans, Phytoseius finitimus Ribaga, Typhlodromus (Anthoseius) rapidus Wainstein, Typhlodromus (Anthoseius) sp., Amblyseius (andersoni?) sp. (Phytoseiidae); Czenspinskia sp. (Winterschmidtiidae); Dendroptus arboreus Mitrofanov & Sharonov, Dendroptus liber Mitrofanov & Livshitz and Tarsonemus sp. (Tarsonemidae). Five species, L. woolleyi, T. meshkinensis, D. liber, D. arboreus and A. striatus, are new records for Turkey.
Several big-eyed bugs, Geocoris species, are abundant predators in many important agricultural cropping systems. Despite their apparent importance and high visibility little is known about their environmental relationships, niche overlap and species richness. To determine these ecological characteristics of five Geocoris species for use in conservation efforts an extensive sampling was done in 152 localities of Iran. A richness model was developed using a maximum entropy modeling approach (Maxent) and ArcGIS software for the five species based on collection records in conjunction with eight environmental variables. Maps for habitat overlap were created for paired species using ArcGIS 10.2 and ENMTools. The species displayed different overlapping niche ranges from 1.97% to 37.25% in pair-wise comparisons. For species richness three categories (habitats dominated by 0-1, 2-3, and 4-5 species) represented 38.44%, 46.07% and 15.49% of the modeled landscape respectively. A direct relationship was found between humidity and the number of species present in different locations. Understanding the degree of ecological overlap between the Geocoris species, and their effective predation of aphids and mites, is critical in designing biological control methods in agroecosystems.
