Coextinction is a major and growing threat to global biodiversity. One of the affected groups is the eriophyoid mites (Prostigmata: Eriophyoidea) which are highly host plant specific. They have been described from an enormous range of annual and perennial plants from grasses to giant forest trees. It is highly likely that there are huge numbers of undescribed eriophyoid species in the subtropical and tropical regions which harbor an extraordinary wealth of plant diversity. The global total of eriophyoid species is estimated to be at least 250,000 but it could be much higher. However, the continuing destruction and degradation of natural habitat, especially tropical forests, and climate change, together pose extreme, on-going threats to the eriophyoid mites because of their vulnerability to co-extinction with their host plants. It has been reported that one third of all the Earth’s plant species are now at risk of extinction. Together with enormous numbers of other invertebrate species, it is highly likely that many thousands of eriophyoid species are disappearing in the current mass extinction event. Population decline and co-extinction, especially of the invertebrates, are greatly accelerating total biodiversity losses. The termination of habitat destruction and degradation; establishment of large, representative protected areas; restoration of degraded areas; and rapid reduction of fossil fuel use, are urgent tasks. However, the long term conservation of biodiversity can only be achieved through comprehensive social, economic and political reforms across the world that prioritize environmental protection, peaceful coexistence, social justice and the sustainable use of resources.

A new species of the genus Scheloribates (Oribatida, Scheloribatidae) — S. (Scheloribates) arsizonensis n. sp. — is described from Ethiopia, based on adult and juvenile instars, collected from litter and green moss in Arsi Mountains National Park. Adults of the new species differ from S. praestantissimus praestantissimus (Berlese, 1916) in having fusiform, distally pointed bothridial seta, the absence of prolamella, and the presence of well-developed notogastral setae p1. The comparison of juveniles of the new species with juveniles of other Scheloribates species is presented. Juveniles of the new species can be distinguished from the other known juveniles of S. (Scheloribates) by the presence of two strong, long, longitudinal, dorsolateral folds on the gastronotum in all instars, long gastronotic seta c3, which is distinctly longer than other gastronotic setae in nymphal instars, the presence of vestigial gastronotic seta h3 in larva, and in the absence of aggenital setae in deutonymph.

Dermatophagoides pteronyssinus (Trouessart, 1897) (Acariformes: Astigmata: Pyroglyphidae) is amongst the most common house dust mites (HDMs) species in Europe. Vacuuming is commonly employed as a method for the recovery for the subsequent quantification of mite densities. The vacuuming protocols employed and their efficiencies are frequently unreported. In this study, a constant-flow vacuum sampler was used to evaluate the recovery of laboratory-reared D. pteronyssinus from cotton, denim or fleece. Two vacuuming protocols were employed. Protocol 1 (P1) entailed a single unidirectional pass of the vacuum head across the fabrics for 60, 90 or 120 seconds. For Protocol 2 (P2), fabrics were vacuumed twice (laterally followed by diagonally) for the same time periods. Vacuuming was carried out on fabrics seeded with live mites (LM), dead mites (DM), and live mites, which were applied to fabric surfaces for 10 minutes and then euthanized by freezing prior to vacuum sampling (EM). There was a significant difference (P<0.001) in mean HDMs recovery with regard to mite viability (LM, DM, EM), fabric type (cotton, denim, fleece), duration of sampling (60, 90, 120s) and vacuuming protocols employed (P1, P2). The numbers of mites recovered from fleece (compared to cotton and denim) were lower for each treatment type where LM and EM were deployed. Overall, the use of protocol 2 resulted in the greatest mean percentage recovery (>80%) of dust mites for all fabrics combined. Recovery rates were also influenced by entrapment of mites (or active attachment) in the fabric microstructure within the weave. The results have implications for the standardisation of mite recovery from fabrics by means of vacuuming.

The water mite Rutripalpus limicola Sokolow, 1934, can be considered exceptionally rare. It shows a scattered distribution range and, until recently, was known from six sites across Europe only. This strictly spring-dwelling species has a highly localised distribution, presumably due to its specific ecological requirements. We present the first records of R. limicola in the Netherlands and review the current state of knowledge on its distribution and biology. In addition to the previously existing morphology-based investigations, we provide a phylogenetic placement based on 28S rRNA gene data and shed light on the controversial systematic position of R. limicola: In contrast to the previously hypothesised Lebertioidea-relatedness of the isolated, monotypic family Rutripalpidae, our results reveal a putative Hydryphantoidea association. Moreover, we discuss the host-parasite association of R. limicola larvae and the dipteran family Ptychopteridae. Combined with additional information derived from the new records from the Netherlands, we contribute to a better understanding of this elusive species' biology and phylogenetic position.

On the basis of females and males found on the adult beetles of the mycophagous tenebrionid Diaperis boleti (L.) and on the polypore fungi Fomitopsis betulina, Laetiporus sulphureus, and Cerioporus squamosus infested with this beetle, which serve as a specific phoretic host for the new species, a new blattisociid mite, Lasioseius boleti sp. nov. was described. The new species is characterised by a pronounced sexual dimorphism of the dorsal chaetotaxy, which is unusual for the genus, and by several features more typical of other highly specialized fungicoles among the mesostigmatic mites than of other species of Lasioseius Berlese, such as the genera Hoploseius Berlese (Blattisociidae), Mycomelichares Mašán and Joharchi (Melicharidae), and Bulbolaelaps Faraji, Zare and Rahmani (Digamasellidae). The new species is unusual among the known congeners mainly because of its unusual bionomy, sexual dimorphism, presence of unequal setae that vary greatly in length and form in both sexes, moderately shortened peritremes, sharp cheliceral teeth, and brush-like tritosternum.

This species is the most similar to Z. quadrivertex (Halbert, 1920), but differs from it mainly by the shape of notogastral setae, posterior tectum of notogaster and lack of postanal porose area Ap, which in Z. quadrivertex is present. In Z. svanhovdi, the prodorsal seta in is long, translamella is narrow, notogastral setae are short and distally pliable, notogastral porose areas are usually oval and of medium size, but Aa can be larger, especially in males. Dorsal crest on tarsus I is present. The cytochrome oxidase I (COI) barcodes (length: 658 bp) of five specimens of the new species are provided; the maximum variation within the species was 2.41% (p-dist). The morphology and ecology of the new species is compared with other Zachvatkinibates species.

The predatory mite, Neoseiulus neoagrestis Khaustov and Döker (Acari: Phytoseiidae), recently described as new species for science, but seems to have a great potential to be used in biological control. In this study, as a first step to determine the optimum temperature (between three temperatures tested) for its mass rearing, we studied its biological characteristics and life table parameters fed on Tyrophagus putrescentiae (Schrank) (Acari: Acaridae) at three different temperatures (20, 25, and 30 °C) under laboratory conditions. Results show that immature development, oviposition period as well as reproductive potential of this predator are significantly vary depending on the temperature. The immature developmental times and adult longevity for females, are ranged between 5.42 to 10.42 days and 39.88 to 74.12 days, based on the temperature, respectively. Average total number of eggs laid by per female at 25 °C (62.29) and 30 °C (58.65) are more or less similar but higher than that determined at 20 °C (41.46). The highest net reproductive rate (R0) is 29.066 (offspring/individual) at 25 °C. In addition, the highest intrinsic rate of natural increase (r) is 0.241 day-1 at 30 °C. Furthermore, the highest finite rate of increase (λ = 1.272 day-1), and the shortest mean generation time (T = 13.416 days) and doubling time (DT = 2.874 days) are also determined at 30 °C. Our results demonstrate that N. neoagrestis successfully completed immature development, and can survive and reproduce at all tested temperatures. Nevertheless, a series of biological characteristics of this predator are differentially affected by the temperature. Finally, 25 °C and 30 °C seems to be more suitable for mass rearing of this predator on T . putrescentiae. Further studies should be conducted to determine biological characteristics and life table parameters of N. neoagrestis on several important pests such as spider mites, whiteflies and thrips.

The highest net reproductive rate (R0) is 29.066 (offspring/individual) at 25 °C. In addition, the highest intrinsic rate of natural increase (r) is 0.241 day-1 at 30 °C. Furthermore, the highest finite rate of increase (λ = 1.272 day-1), and the shortest mean generation time (T = 13.416 days) and doubling time (DT = 2.874 days) are also determined at 30 °C. Our results demonstrate that N. neoagrestis successfully completed immature development, and can survive and reproduce at all tested temperatures. Nevertheless, a series of biological characteristics of this predator are differentially affected by the temperature. Finally, 25 °C and 30 °C seems to be more suitable for mass rearing of this predator on T . putrescentiae. Further studies should be conducted to determine biological characteristics and life table parameters of N. neoagrestis on several important pests such as spider mites, whiteflies and thrips.","PeriodicalId":48866,"journal":{"name":"Acarologia","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43749586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
