This study assesses the effectiveness of Effective Microorganisms (EM) technology in restoring Lake Jeziorko (Poland), using water mites (Hydrachnidia) as sensitive bioindicators of habitat change. During the monitoring period lasting a total of 35 months (samples were taken each time in July for three years) across littoral and profundal zones, collecting 9,739 water mite individuals from 38 species. Bathymetric analysis confirmed a decrease in bottom sediment thickness, which probably triggered a clear response in benthic fauna. Although the initial year showed a lake-wide increase in species richness, long-term trends reveal a split: littoral communities declined due to external nutrient inputs and cyanobacterial blooms, while profundal communities (dominated by typical lake taxa such as Neumania limosa and Piona stjordalensis) remained stable and showed signs of improved sediment oxygenation. These findings indicate that while probiotic bioremediation effectively conditions deep-water habitats and reduces sediment volume, it is not sufficient alone to counter external eutrophication pressures. Additionally, these studies indicate that profundal aquatic mite communities show a clear improvement in profundal conditions, while littoral water mites indicate that the ecological situation did not improve permanently.https://www.persianacarology.org/article_242639_9d43b6d8bc2e0cf1e0e67c0257f26497.pdfAcarological Society of IranPersian Journal of Acarology2251-816915320260715Sublethal effects of fenpropathrin on the oxalis spider mite, Tetranychina harti (Ewing) (Acari: Tetranychidae)15030215030210.22073/pja.150302ENLi-HongYangSchool of Life Sciences, Mianyang Teachers' College, Mianyang, Sichuan 621000, P. R. China0009-0002-4159-5808Journal Article20250710The sublethal effects of fenpropathrin on the oxalis spider mite, Tetranychina harti (Tetranychidae) were investigated. The results showed that, relative to the control group, sublethal doses of fenpropathrin significantly shortened the developmental duration of immature offspring in the LC15 group (P < 0.05) but significantly prolonged it in the LC30 group (P < 0.05). Furthermore, these sublethal exposures shortened the pre-oviposition period while prolonging the oviposition period of F1 female adult mites. Notably, a significant reduction in mean fecundity per female was observed only in the LC15 group compared to the control (P < 0.05). The cumulative survival rate curves and age-specific fecundity curves indicated that sublethal concentrations (LC15 and LC30) of fenpropathrin did not exert a clearly adverse effect on the survival or fecundity of Tetranychina harti. Both treatment groups exhibited higher net reproductive rates (R0) than the control. Similarly, the intrinsic rates of increase (rₘ) in the LC15 and LC30 groups exceeded that of the control, and the finite rates of increase (λ) in both treatment groups were also higher. In addition, the population doubling time (DT) was shorter in the treatment groups than in the control. These findings suggest that sublethal exposure to fenpropathrin may compromise its efficacy in controlling this mite population.https://www.persianacarology.org/article_242970_947b93853b345c30cec3d68a333109b1.pdfAcarological Society of IranPersian Journal of Acarology2251-816915320260715Complementary description of Flagroseius euflagellatus (Karg) (Mesostigmata: Phytoseiidae) from Cat Tien National Park, Southern Vietnam15030315030310.22073/pja.150303ENVladimir A.KhaustovUniversity of Tyumen, Institute of Environmental and Agricultural Biology (X-BIO), Tyumen, Russia0000-0003-2831-7213Vladimir M.SalavatulinUniversity of Tyumen, Institute of Environmental and Agricultural Biology (X-BIO), Tyumen, Russia0000-0003-2928-5727Duc TrungNguyenSouthern Branch of Joint Vietnam-Russia Tropical Science and Technology Research Center, Ho Chi Minh City, Vietnam0009-0004-3097-2465Journal Article20260414The phytoseiid mite Flagroseius euflagellatus (Karg) is redescribed based on female and male specimens collected on Citrus maxima (Burm.)

We provide a comprehensive redescription with detailed illustrations and measurements of both sexes, and documenting previously overlooked morphological structures, including the complete setation patterns of all leg segments.https://www.persianacarology.org/article_245879_d406b702a7d6d7c118d56754508ddc3f.pdfAcarological Society of IranPersian Journal of Acarology2251-816915320260715Laboratory testing of the effects of diflovidazin on egg production and on transmaternal ovicidal activity in Tetranychus urticae Koch (Acari: Tetranychidae)24704510.22073/pja.150308ENÁrpádSzabóDepartment of Entomology, Institute of Plant Protection, Hungarian University of Agriculture and Life Sciences, Budapest, Hungary0009-0004-1692-6075MártaLadányiDepartment of Applied Statistics, Institute of Mathematics and Basic Science, Hungarian University of Agriculture and Life Sciences, Budapest, Hungary0000-0003-3114-8289ViktóriaNagyAgro-Chemie Ltd., Bányalég str. 47-59., Budapest, HungaryJournal Article20251228The transmaternal properties of diflovidazin were examined under laboratory conditions on Tetranychus urticae. To assess its transmaternal ovicidal effect, leaf discs were dipped in a 100 ppm diflovidazin solution, after which adult females were allowed to feed on the treated surfaces for either 2 or 48 hours. The females then laid eggs on an untreated surface over five consecutive 7-hour periods. Egg mortality was evaluated based on exposure duration and time elapsed since exposure. After being removed from the treated surface, 100% of the eggs laid by females in the first 7-hour period were non-viable. However, mortality—and thus the effect—gradually decreased in subsequent periods, with eggs laid after 28 hours exhibiting mortality levels comparable to naturally occurring rates. Notably, the length of the exposure period did not influence the rate at which egg mortality declined. The effect on egg production was also examined. Females were allowed to lay eggs on treated leaf discs, but the treatment did not significantly alter the number of eggs produced per female. These findings indicate that while diflovidazin effectively induces high egg mortality, it does not reduce overall egg production. Our results suggest that diflovidazin temporarily sterilizes females, likely because developing eggs absorb the active substance from the female's system.https://www.persianacarology.org/article_247045_bf9127fd93890814ab3f240261b3d8fc.pdfAcarological Society of IranPersian Journal of Acarology2251-816915320260715First record of the genus Phauloppia (Acari, Oribatida, Oribatulidae) in Ethiopia, with description of a new arboreal species15031015031010.22073/pja.150310ENSergey G.ErmilovUniversity of Tyumen, X-BIO Institute, Tyumen, Russia0000-0002-0913-131XVladimir M.SalavatulinSevertsov Institute of Ecology and Evolution, Russian Academy of Sciences, Laboratory of Soil Zoology and General Entomology, Moscow, Russia0000-0003-2928-5727Leonid B.RybalovSevertsov Institute of Ecology and Evolution, Russian Academy of Sciences, Laboratory of Soil Zoology and General Entomology, Moscow, Russia0000-0003-2928-5727Journal Article20260424The genus <em>Phauloppia </em>(Oribatida, Oribatulidae) is recorded for the first time from Ethiopia.
