The two-spotted spider mite, Tetranychus urticae Koch, one of the major pests of various agricultural plants, causes many problems on agricultural, horticultural and ornamental plants. In recent years, using plant-derived compounds such as essential oils and extracts was attended for their insecticidal and acaricidal properties. Mentha pulegium is a native plant of temperate Asia, was identified as an acaricidal plant for the first time in this study. The impact of essential oil of this plant on fumigant toxicity, LT₅₀, oviposition deterrent activity and repellency against Tetranychus urticae was studied at different concentrations. The results stated that M. pulegium oils had high toxicity on eggs and adults of two-spotted spider mite (LC₅₀ was 2.57 and 2.25 μL L⁻¹ for eggs and adults, respectively). In addition, all tested concentrations had oviposition deterrent activity and repellency on adults of this mite.

New records of water mites collected in 2022 and 2023 from northeastern Iran and southwestern Turkiye, are presented. DNA barcodes of 58 specimens, morphologically assigned to 13 species were newly generated. An integrative approach that combines morphology and DNA barcodes revealed three new species for water mite fauna of Türkiye, i.e. Lebertia variolata Gerecke, 2009, Torrenticola baueri Bader & Sepasgozarian, 1987 and Atractides zagrosensis Pešić, Saboori & Asadi, 2016, significantly widening their so far known area of distribution. Torrenticola ramini Bader, 1988, is reported for the first time since its original description, and T. eseni sp. nov. is described as new to science.

New records of water mites from Iran and Turkey revealed by DNA barcoding are presented. DNA barcodes were recovered from 44 water mite specimens morphologically assigned to 18 species. The DNA barcoding data for the twelve species were uploaded into the BOLD database. One species of the Hygrobates longiporus-complex, H. thori Pešić & Smit sp. nov. is described as new for science and Hydrodroma persica Pešić & Saboori, 2012 is reported as new for Turkey. We propose to lower the taxonomic status of Hydrodroma golestanica to a subspecies of H. torrenticola, i.e. H. torrenticola golestanica nov. stat.

The life history and predation rate of the predatory mite, Typhlodromus bagdasarjani Wainstein & Arutunjan, fed on the eggs of two-spotted spider mite, Tetranychus urticae Koch, were studied for both females and males under laboratory conditions at 25 ± 1°C, 75 ± 5% Relative Humidity (RH) and 16Light (L) : 8Dark (D) hour photoperiod. According to the age-stage, two-sex life table, the intrinsic rate of increase (r), finite rate of increase (λ), net reproductive rate (R₀), gross reproductive rate (GRR) and mean generation time (T) were 0.143 day⁻¹, 1.154 day⁻¹, 12.91 offspring, 16.7 offspring and 17.8 days, respectively. Moreover, the number of T. urticae eggs consumed by different stages/sexes of T. bagdasarjani was estimated using the age-stage, two-sex life table and indicated that the consumption rates increased from nymph to adult in both sexes. Also, our results showed that females consumed prey eggs 22 times more than males. The net predation rate (C₀) and transformation rate from prey population to predator offspring (Q_p) were 885.91 mite eggs and 68.62, respectively. The results showed that T. bagdasarjani can successfully survive and reproduce on T. urticae eggs on rose.

Ovacarus longisetosus Hajiqanbar and Husband n. sp. (Acari: Podapolipidae) is described and illustrated from Amara (Paracelia) saxicola Zimm. (Coleoptera: Carabidae) from northeastern Iran and compared with previously described species, Ovacarus clivinae Stannard and Vaishampayan, 1971 and O. peellei Husband, 1974 from Illinois and North Dakota, U.S.A. New records of Podapolipidae from Iran include: Tarsopolipus massai Husband, 1989 from an undetermined scarab beetle, Coccipolipus macfarlanei Husband, 1972 from Coccinella septempunctata L. and C. undecempunctata L., Dorsipes sp. and Eutarsopolipus sp. from Amara (Paracelia) saxicola.
