The development and life history parameters of Neoseiulus agrestis feeding on the storage mite, Thyreophagus sp., were studied at three different temperatures of 20, 25, and 30 °C. The results show that juvenile development and oviposition period as well as reproductive potential of this predatory mite are significantly affected by the temperature. The development times of immature and the life expectancy of adults ranged from 11.36 to 6.06 days and 58.71 to 38.65 days, respectively, depending on the temperature. The average total number of eggs laid per female at 20 °C (27.21), 25 °C (46.38), and 30 °C (61.12) differed significantly from each other. The highest net reproductive rate (R0) was 51.95 (offspring/individual) at 30 °C, although there was no significant difference from that obtained at 25 °C (37.10). Furthermore, the highest intrinsic rate of increase (rm) is 0.286 day-1 at 30 °C. Moreover, the highest finite rate of increase (λ = 1.331 day-1) and the shortest mean generation time (T = 13.786 days) and doubling time (DT = 2.418 days) were also determined at 30 °C. Our results indicate that N. agrestis successfully completed immature development and can survive and reproduce at all temperatures tested. However, a number of biological traits of this predator are affected by the temperature on this food source. Finally, a temperature of 30 °C seems to be more suitable for mass rearing of this predator on Thyreophagus sp. Further studies should be carried out to determine the biological characteristics and life cycle parameters of N. agrestis on various important pests such as spider mites, whiteflies and thrips.

Blackberry (Rubus ulmifolius Scott) is an economically important crop in Mexico. Eriophyoidea mites are among the most important arthropod pests affecting production of this crop worldwide. Despite this, reports on species diversity of Eriophyoidea on blackberry in Mexico are scarce. We sampled six orchards from two municipalities in the state of Michoacan, the most important region for blackberry production. Sampling was carried out monthly between May and November 2018. Only one species of eriophyoid mite was found, Diptacus rubuscolum Trinidad, Duarte and Navia. We conducted a detailed morphological study of this mite and a complementary description is presented. In addition, we obtained partial sequences of the mitochondrial cytochrome oxidase subunit I (mt COI), the 18S and 28S of the rRNA. The duration of each developmental stage was determined under controlled conditions (25 °C, 60% RH and 12:12 light regime). We confirmed the identity of D. rubuscolum by comparing partial sequences of the D2 region within the 28S rRNA from our samples and sequences retrieved from GenBank. Overall, morphological characteristics were in line with the type specimens. However, some differences on body shape and empodium structure were pointed out. The developmental stages of D. rubuscolum were egg, larva, nymphochrysalis, nymph, imagochrysalis and adult, with a mean duration of 75 (±10), 56 (±9), 21 (±7), 41 (±8), 19 (±6) and 114 (±12) hours respectively. The information produced provides insight and knowledge on the occurrence of this species on blackberry in Mexico as well as on original biological aspects.

A new feather mite species, Allodectes archilochus sp. n. (Pterodectinae: Rhamphocaulini) is described from the ruby-throated hummingbird, Archilochus colubris (Apodiformes: Trochilidae), in Manitoba, Canada. This is the first record of the genus Allodectes on hummingbirds in the northern part of North America. The new species is close to A. thaluraniae Hernandes, 2017, and distinguished from the latter in the following features: in both sexes, the anterior margin of the hysteronotal shield is deeply concave; in males, setae d2 are situated at the midlevel of metapodosomal sclerites, and tarsus IV is without extension on the inner margin; in females, the anterolateral extensions of the prodorsal shield do not extend to the lateral margins of propodosoma, and the anteromedian area of the hysteronotal shield is covered with dense striation. A checklist of the 15 currently known Allodectes species is provided.

Neoseiulus ramabettaensis n. sp. Döker and Jose is described based on specimens collected from Karnataka, India. The new species is accommodated to the cucumeris species group and ceratoni species subgroup in the genus Neoseiulus Hughes (Acari: Phytoseiidae). The morphological characters including conspicuously longer setae j1 and j3, in addition to Z4 and Z5, chelicera dentition, wider ventrianal shield at anterior corners, large crescentic preanal pores, absence of macroseta on legs II-IV, and presence of macroseta on genu I distinguished the new species from its congeners in the ceratoni species subgroup. The current study describes a macroseta on leg I (SgeI) for a species listed in the ceratoni species subgroup for the first time. Indeed, the presence of SgeI, and the absence of macroseta on leg IV are unusual characters for the genus Neoseiulus, except SgeI present in a few species in Neoseiulus desertus species group. Therefore, chaetotaxy of legs frequently used in the systematics of other groups of Mesostigmata which are closely related to the phytoseiid mites, seems to be an important morphological character and should be included in future descriptions. In addition, we constructed an identification key for the Indian species of the genus.
根据从印度卡纳塔克邦采集的标本，描述了拉马贝塔新虫（Neoseulus ramabettaensis n.sp.Döker and Jose）。该新种隶属于新叶螨属（Acari：Phytoseidae）的cucumeris种群和角龙属（ceratoni）亚群。除Z4和Z5外，其形态特征包括明显较长的刚毛j1和j3、螯齿列、前角较宽的腹侧盾、较大的新月形肛门前孔、II-IV腿上没有巨大目和I属上有巨大目，这些特征将该新种与其在角龙属亚群中的同类区分开来。目前的研究首次描述了一个被列入角龙属物种亚组的物种的腿I上的巨大目（SgeI）。事实上，除了SgeI存在于Neoseulus desertus物种群中的少数物种中之外，SgeI的存在和腿IV上的macroseta的缺失是Neoseulus属的不寻常特征。因此，在与植物寄生螨密切相关的中斯的目其他类群的系统学中经常使用的腿毛状体似乎是一个重要的形态学特征，应纳入未来的描述中。此外，我们构建了该属印度物种的识别密钥。

The supplementary description of the oribatid mite species Discoppia (Cylindroppia) cylindrica (Pérez-Íñigo, 1965) (Oribatida, Oppiidae) is presented, based on materials collected from deep layers of coastal sandy soils in the Republic of Dagestan, eastern Caucasus. The morphology of exobothridial seta, gnathosoma and ovipositor, and the identification of leg setae and solenidia are given for the first time for this species. The revised generic diagnosis, identification key, distribution, and habitats of all known representatives of Discoppia Balogh, 1983 are presented. Some taxonomic nuances within Discoppia are discussed, resulting in the following proposals: Oppia bifidus Bayoumi and Al-Khalifa, 1985 is a junior synonym of D. (C.) cylindrica; Oppia agricola Fujikawa, 1982 is not synonym of D. (C.) cylindrica and transferred to the genus Microppia Balogh, 1983; Oppia tenuis Hammer, 1958 is not representative of Discoppia; Discoppia (Cylindroppia) rostroincisa Subías and Rodríguez, 1986 n. stat. (instead of the existing subspecies status). Together with D. (C.) cylindrica, in the same samples, two rare Oppiidae species were found: Oxyoppia (Oxyoppiella) minuscula Hugo-Coetzee, Lotfollahi, Abbasi-Kalo and Movahedzade, 1917 (known only from the open habitats in Iran) is first recorded in Russia; Graptoppia (Stenoppia) boucheri Ermilov and Frolov, 2021 (known from passalid beetles collected in Ghana and Gabon, West Africa) is first found in the Palaearctic. Both findings in Dagestan are among the northernmost records of their semicosmopolitan subgenera.

Phytoseiid mites have been considered the most promising predators for the control of pest mites and small insects. Their use in solanaceous crops for the biological control of major mite pests represents an important challenge and requires continued research. This study aimed at investigating the phytoseiid species and their associated phytophagous mites on eggplant (Solanum melongena), tomato (Solanum lycopersicum) and black nightshade (Solanum nigrum) in the Syrian coastal region between 2018 and 2020, at 40 sites. A total of 12 species of the three subfamilies (Amblyseiinae Muma, Phytoseiinae Berlese, and Typhlodrominae Scheuten) were collected, with Amblysiinae being the most represented. Among them, Amblyseius andersoni (Chant) is a new record for the Syrian fauna. Phytoseiulus persimilis Athias-Henriot was the most abundant (223 specimens; 47.3%) and frequent (found in 22 out of 40 sites) species collected on all plant species surveyed and the only common phytoseiid species in greenhouses. The second most abundant species was Neoseiulus californicus (McGregor) (83 specimens: 17.6%), while the second most frequent was Phytoseius finitimus Ribaga (8 sites). Species found in this study should be considered in future research on phytoseiid mites as biological control agents of pests of tomato and eggplant cultivated in greenhouses and open fields in this region.

The diverse biogeography of Chile provides it an ideal field to study the influence of environmental factors on plant and animal biodiversity. Some small animal species are distributed throughout dissimilar environmental zones, such as the biogeographic provinces, Mediterranean, Temperate Forest and Patagonia. One of these species is Oligoryzomys longicaudatus (Long-tailed pygmy rice rat), which is parasitized by mites of the genus Mysolaelaps (Fonseca, 1936). In this context, the present study describes the parasitic infestation rates of Mysolaelaps microspinosus on O. longicaudatus and evaluates its relationship with biotic factors (sex and host body mass) and abiotic factors (biogeographical province and season). Of 328 O. longicaudatus analyzed, 68 Mysolaelaps positive cases were obtained. Prevalence and mean abundance were 20.7% and 0.708, respectively. Multifactorial logistic and negative binomial regressions were performed to evaluate the effect of biotic and abiotic factors on prevalence and mean abundance. Both rates were significantly and directly related with biogeographic province and season, with higher rates in Mediterranean and Temperate Forest provinces and in winter and spring. The mean abundance had a significant direct relationship with host body mass, describing higher rates on heavier individuals. These results suggest that environmental factors such as temperature and food availability, strongly affect the ecology of M. microspinosus. Here we proposed that the southern limit for the genus in Chile is 47°S, mainly, due to colder temperatures. Also, biotic factors such as the weight of unpregnant hosts are relevant in parasite infestations, due to a greater parasitic load capacity by heavier individuals.

Some small animal species are distributed throughout dissimilar environmental zones, such as the biogeographic provinces, Mediterranean, Temperate Forest and Patagonia. One of these species is Oligoryzomys longicaudatus (Long-tailed pygmy rice rat), which is parasitized by mites of the genus Mysolaelaps (Fonseca, 1936). In this context, the present study describes the parasitic infestation rates of Mysolaelaps microspinosus on O. longicaudatus and evaluates its relationship with biotic factors (sex and host body mass) and abiotic factors (biogeographical province and season). Of 328 O. longicaudatus analyzed, 68 Mysolaelaps positive cases were obtained. Prevalence and mean abundance were 20.7% and 0.708, respectively. Multifactorial logistic and negative binomial regressions were performed to evaluate the effect of biotic and abiotic factors on prevalence and mean abundance. Both rates were significantly and directly related with biogeographic province and season, with higher rates in Mediterranean and Temperate Forest provinces and in winter and spring.

Several phytoseiid species are excellent biological control agents for suppressing mite pest populations in many crops and preventing yield losses. This paper aims to improve the knowledge of Phytoseiidae diversity in citrus orchards and argan forest in central western Morocco. The surveys were conducted between April and October during three successive years (2017–2019), in nine conventional citrus orchards covering an area of more than 3,000 hectares and on uncultivated plants in argan forest at an altitude ranging from 150 to 700 meters. Twenty-nine species belonging to 15 genera were found, seven of them being new for the Moroccan fauna: Amblyseius largoensis, A. swirskii, Amblyseiella setosa, Euseius batus, E. dossei, Paragigagnathus molestus, and Cydnoseius negevi. Species of nine genera were found on citrus leaves: Neoseiulus, Amblyseius, Amblyseiella, Transeius, Phytoseiulus, Euseius, Phytoseius, Typhlodromus, and Paraseiulus. Stah AlMadina (24.8%), Ouled Abdellah (15.9%), Nour (14.3%) domains contained a high number (more than 60.2%) of individuals in the collected samples. Malva parviflora, Convolvulus althaeoides, Solanum nigrum, Bryonia dioica, Withania somnifera would be interesting companion plants to be associated in the inter-rows in citrus orchards in this region to ensure sustainability, because they host high densities and diversities of Phytoseiidae. A key of females of all recorded Moroccan species until now is provided.
