Abstract This paper records six species and five genera of mites in the family Laelapidae from soil in Punjab, Pakistan. Five species are recorded from Pakistan for the first time – Euandrolaelaps karawaiewi (Berlese, 1904), Gaeolaelaps minor (Costa, 1968), Gymnolaelaps kabitae Bhattacharyya, 1968, Ololaelaps translineatus (Barilo, 1991), and Stratiolaelaps scimitus (Womersley, 1956). Cosmolaelaps lutosus sp. nov. is described as a new species.

Abstract Thirty-four species of oribatid mites (Oribatida), belonging to 29 genera and 14 families, were collected from Saona Island, Southeast Dominican Republic. A new species of the genus Pergalumna—P. (Pergalumna) saonaensis sp. nov.—is described from leaf litter of the mixed forest.

Abstract Two new species of oribatid mites (Oribatida)—Hermannobates neotropicus sp. nov. (Hermanniellidae) and Mucrobates venezuelaensis sp. nov. (Scheloribatidae)—are described, based on materials collected from sweep sample in the cloud forest in Western Venezuela. The genus Mucrobates is recorded in the Venezuelan fauna for the first time. Hermannobates neotropicus sp. nov. differs from the closely related species, H. intermedius Călugăr, 1990, by length and morphology of the bothridial seta. Mucrobates venezuelaensis sp. nov. differs from the closely related species, M. cayoaguaensis Ermilov & Kontschán, 2021, by the body size, the length of the bothridial and exobothridial setae, the presence of the pedotectum II, keel-shaped ridge and seta v’ on the leg genu II, and the location of the adanal seta ad₁.

Abstract During a field survey of eriophyoid mites in Dogijan village (Marand county, East Azerbaijan province, Iran) in late spring 2023, one new eriophyid species (Acari: Eriophyoidea: Eriophyidae) on Chardinia orientalis (L.) Kuntze (Asteraceae) was discovered, illustrated, described, and named as Aceria dogijaniensis sp. nov. The mites cause tight leaf edge rolls of different length with pale blotches on their type host plant. In addition, a population of similar mites was collected on Centaurea sp. (Asteraceae) with leaf galls made by Subanguina sp. (Nematoda: Secernentea: Tylenchida: Anguinidae) at the same locality on the same date. Few quantitative and qualitative differences were found between the two populations collected on the two host plants. In this study, we provided a list of Aceria spp. associated with Asteraceae in Iran.

Abstract This study reports on 10 species of the genus Copidognathus Trouessart, 1888 collected from sand sediment habitats and macroalgae in Muğla and Antalya, located along the eastern Mediterranean Sea, Türkiye. Three species, C. cribosoma (Police, 1909), C. figeus Bartsch, 1976 and C. humerosus (Trouessart, 1896) are recorded from the Turkish coasts for the first time, extending their known distribution to the Levantine Sea. Juvenile stages of C. brachyostomus, C. cribosoma, C. gibbus, C. humerosus, C. lamelloides, C. magnipalpus, C. remipes and C. tabellio were also identified and illustrated, with the nymphs of C. cribosoma, C. remipes and the larvae of C. gibbus and C. humerosus being documented for the first time. Additionally, this study provides detailed observations on the adults of C. gibbus, C. majusculatus and C. tabellio which were previously recorded in Türkiye.

Abstract This checklist of house dust mites (Acari: Trombidiformes, Sarcoptiformes) from Türkiye is based on published data and private collections. The species are listed alphabetically. In total, 33 dust mite species and their zoogeographical distributions are presented. This study represents the first checklist of house dust mite fauna in Türkiye.

Abstract Effects of cyflumetofen and clofentezine were evaluated on Tetranychus urticae Koch, under laboratory conditions. LC₅₀ values of cyflumetofen and clofentezine against eggs were 0.8 µg a.i./mL and 0.42 µg a.i./mL, respectively. Sublethal effects of these compounds on the life table parameters of T. urticae were evaluated by exposing mites to LC₅₀ and LC₂₅ concentrations. The developmental time of male and female T. urticae were significantly affected by both acaricides. Moreover, exposure to LC₂₅ and LC₅₀ concentrations of cyflumetofen or clofentezine significantly reduced net reproductive rate (R₀), finite rate of increase (λ), and intrinsic rate of increase (r). The LC₂₅ and LC₅₀ treatments showed strong effects on both survivorship, fecundity, and intrinsic rate of increase. Our findings indicated that lethal and sublethal exposure to cyflumetofen or clofentezine result in significant alteration of life-history characteristics of T. urticae. Our findings suggest that these acaricides are promising candidates for use in management programs of this major pest.

Abstract Laboratory tests and semi-field evaluation were carried out to examine the acaricidal effect of four concentrations of diatomaceous earth (DE) and sulfur against four mites: Tetranychus urticae (Tetranychidae), Rhizoglyphus echinopus (Acaridae), Tyrophagus putrescentiae (Schrank) (Acaridae), and Amblyseius swirskii (Phytoseiidae). Results revealed that mortality increased as both time and concentration increased. Tetranychus urticae was the most affected mite; LC₅₀ values were 70.4 and 92.0 for immature and adult stages, respectively, after 7 days. For the LC₅₀ concentrations examined, a significant decrease in the total number of immature and adult stages of all mites during seven days was noticed. Under semi-field conditions, the LC_50s were calculated for (DE) and sulfur against T. urticae on cucumber plants. The reduction percentage of T. urticae was 66.67 and 50% for (DE) and sulfur, respectively, after seven days of application, with significant differences.
