A brief introduction of Chinese Limnesiidae taxonomy is provided. Adults of two new species, Limnesia (Limnesia) lupingae Li & Guo sp. nov. and Limnesia (Limnesia) macrophthalma Li & Guo sp. nov., from Heilongjiang and Hubei provinces respectively, are described in detail. Subtle structures are recorded with scanning electron micrographs. In addition, deutonymphs of two new species are also described in detail and compared with the adults in discussion.

Even as new chemical substances show promise as selectivity for controlling pests due to their high effectiveness in inhibiting pests, their side effects on non-target organisms must nevertheless be evaluated before they can be included in integrated pest management systems. We examined both lethal and sublethal (LC₁₀ and LC₃₀) effects of cyflumetofen on the predatory potential of the Amblyseius swirskii Athias Henriot (Acari: Phytoseiidae) which is among the most dominant mite predators in tropical agricultural agroecosystems. The experiments were performed under laboratory conditions at 25 ± 2°C, 65 ± 5% relative humidity (RH), and a photoperiod of 16:8 (L: D) hours. Results were analyzed based on age-stage, two-sex life table analysis. The data showed that sublethal concentrations of the pesticides suppress fecundity, total life span (both female and male individuals), and the intrinsic and finite rate of increase significantly. The result show, the fecundity in the LC₁₀, LC_30, and control was 14.97, 11.87, and 17.28, eggs/female for LC₁₀ and LC₃₀, respectively, showing significant differences. The values of the intrinsic rate of increase (r) on the above-mentioned concentrations were 0.1333, 0.1166, and 0.1430 day^-1, respectively. Consequently, according to the data, it seems that the selected acaricide is not suitable to use with A. swiriskii in integrated pest management programs due to their unfavorable effects on the population parameters of this predatory mite.

Neoseiulus californicus is a key natural predator of spider mites and small arthropod pests. Although vitellogenin (Vg) and vitellogenin receptor (VgR) genes are important regulators of oocyte maturation, egg formation, and embryonic development in spider mites and ticks, their role in phytoseiid mites is less understood. Investigating the reproductive mechanism of predatory mites is crucial for understanding their reproduction and evolution. In this study, three Vg genes and one VgR gene were identified, cloned, and characterized in N. californicus. Vg1, Vg2, Vg3, and VgR mRNAs were 6066, 5728, 4515, and 5331 bp long, encoding proteins comprising 1851, 1849, 1471, and 1722 amino acids, respectively. Temporal expression analysis revealed elevated Vg1, Vg2, and VgR levels in fertilized female adult mites, whereas Vg3 exhibited peak expression during the developmental stage. RNA interference–mediated suppression of Vg1 and Vg2 resulted in 14.66% and 11.59% decreases in fecundity, respectively. Vg1 silencing notably reduced egg hatching rate and female offspring ratio. In contrast, Vg3 and VgR silencing had no significant impact on fecundity and egg hatching rate. These findings provide insights into the regulatory roles of Vg and VgR in predatory mite reproduction, offering a theoretical foundation for understanding their evolution and reproductive strategies.

During field surveys of eriophyoid mites in Razavi and North Khorasan provinces (Iran) in summer 2023, two new Aceria spp. (Acari: Eriophyoidea: Eriophyidae) on Amaranthaceae plants were discovered, illustrated and described: Aceria sodae sp. nov. on Soda rosmarinus (Bunge ex Boiss.) Akhani and Aceria esfarayeniensis sp. nov. on Salsola arbusculiformis Drobow. Furthermore, a list of Aceria spp. on Amaranthaceae species around the world, their type host plants and their relationship to hosts are provided.

The results of long-term research on tetranychid and phytoseiid mites in the Transcarpathian region of Ukraine are summarized. Transcarpathian Tetranychoidea are represented by 28 species from 10 genera, and the same list for Phytoseiidae included 49 species from 11 genera. For 77 species of mites from 21 genera, species composition, abundance, trophic specialization, and biotopic distribution in different altitudinal zones of Transcarpathia, Ukraine was analysed. Ten species of tetranychid mites (Bryobia rubrioculus, Tetranyhus horridus, Amphytetranyhus viennensis, Eotetranycuus carpini, E. quercicola, Neotetranychus rubi, Oligonychus ununguis, Panonychus ulmi, T. turkestani and T. urticae), and 11 species of phytoseiid mites (Neoseiulus umbraticus, Kampimodromus aberrans, Amblyseius andersoni, A. rademacheri, Euseius ucrainicus, Dubininellus echinus, D. juvenis, Typhloctonus aceri, T. tuberculatus, Anthoseius (A.) rhenana and A. (A.) clavata) were common to all three studied altitudinal zones. The species diversity of tetranychids was highest in the lowlands (23 species), slightly lower in the foothills (19 species), and the lowest in the mountain zone (11 species). For phytoseiid mites, it was the highest in the foothills (38 species), 25 in the lowlands and 21 in mountains. Among the tetranychids, the transzonal species A. viennensis retained its dominant status in all altitudinal zones. In the lowland, the highest rates of occurrence and dominance indices were observed for the species B. rubrioculus and T. turkestani, and in the foothills—for P. ulmi and T. horridus. The species composition of mites in the lowlands and mountains varied the most for both predators and phytophagous mites. Among the tetranychids, the most striking marker species in the mountains were P. ulmi and N. rubi. Only in the mountains were found such phytoseiid species as N. alidis, N. montanus, T. runiacus, T. mutatus, and A. salviae, which could thus be considered strictly mountainous. All of them have fragmented habitats and are tied to mountainous regions. In that altitudinal zone, an exceptionally high occurrence rate and dominance index were established for N. montanus among the phytoseiids. This is most probably due to significantly greater differences in the temperature and humidity regimes and range of host plants and, for predatory mites, prey species. The results of this study provide additional information about the structure of the communities of phytophagous and predatory mites in the natural zones of the mountain landscape and changes in the composition of the communities under the influence of environmental factors and the forage base, which is a consequence of the altitudinal distribution of the investigated biocenoses.

Parasitengona is a diverse group of Prostigmata, including mites with life cycles that include important morphological changes between larva and deutonymph, an evolutionary novelty not shared by its closely related taxa (Halacaridae, Pezidade or Anystidae). Allotanaupodoidea is a superfamily of Parasitengona, known solely by the post-larval instars, that differs from the remaining Parasitengona mainly due to the lack of trichobothria in the prodorsal shield. Allotanaupodoidea has a single family Allotanaupodidae with six species distributed in two subfamilies, Allotanaupodinae Zhang & Fan, 2007 and Paratanaupodinae Zhang & Fan, 2007, with one and two genera, respectively. In the present study, we describe the larva of Allotanaupodus winksi Zhang & Fan, 2007 from New Zealand associated with the deutonymph by means of cytochrome oxidase I barcoding. The description reveals a remarkable resemblance between larval and post larval specimens of A. winksi, a condition approached among Parasitengona only by Calyptostomatidae.
