“…Reflecting such a feature of the parasitic phase of mites and hemipterans, Hydrachna larvae are known to attach to the exposed host body areas in direct contact with the water (Redmond and Lanciani 1982;Reilly and McCarthy 1993). In this respect, Hydrachna larvae have an advantage in finding their hosts in water, and they are regarded to be well adapted to aquatic life (Zhavoronkova 2006). In the present study, Hydrachna sp.1 exhibits a clear preference for particular body parts of the host species R. chinensis.…”

Water mites are known to temporarily live on the surface of aquatic insects in their life cycle. Investigations of the host-parasite relationship between water mites and aquatic insects are quite limited in Japan. Therefore, we examined several aquatic hemipterans to clarify the parasitic nature of water mites on aquatic insects. During the survey, the following seven hemipteran species were collected from farm ponds and rice fields in Kanagawa, Yamanashi, and Hyogo prefectures in 2011 and 2012: Appasus japonicus, Appasus major, Laccotrephes japonensis, Aquarius paludum, Ranatra chinensis, Kirkaldyia deyrolli, and Notonecta triguttata. Among these species, water mites were found only on Ap. japonicus and R. chinensis. The water mites were all in a post-larval resting stage and identified as Hydrachna spp. The mites attached to R. chinensis were clearly larger than those on Ap. japonicus. Although mites do not select by host sex and their abundance was not affected by the host body size, their abundance per female host was greater than per male host. Further, the mite parasitism on nymphs was greater than that on adults in Ap. japonicus. Concerning site selection on a host body of R. chinensis for attachment, mites significantly prefer the leg and meso-and metathoraxes to the abdomen, respiratory siphon, and head of a host insect. The results mentioned above accorded well with several studies in Europe.

“…It is well-known that water mites are abundant parasites in aquatic ecosystems, nearly all insect orders with aquatic stages are considered as potential hosts for at least one water mite species (Smith and Oliver 1986). The life cycle of water mites consists of six stages (Smith 1988): the egg, larvae, protonymph, deutonymph, tritonymph, and adult (mostly predators) (Zhavoronkova 2006). Water mite parasitism is necessary for larval feeding and completing its development (Wohltmann et al 2001).…”

Microplastic pollution endangers both aquatic and terrestrial ecosystems. Their spread across the food chain also endangers human health. Wastewater treatment plants (WWTPs) can be viewed as the final barrier between microplastics and the environment. In addition, it is well-known that water mites are abundant parasites in aquatic ecosystems, and nearly all insect orders with aquatic stages are considered potential hosts for at least one water mite species. However, no studies have been conducted to test the direct and indirect effects of parasites on population dynamics in freshwater ecosystems or the role of predators in shaping the behavior and life histories of aquatic organisms. Thus, this work aimed to study the seasonal abundance, distribution, composition, and risk assessment of MPs in surface water, aquatic insects (Coroxide and Notonectidae), and for the first time, water mites (Hydrachnidiae), as well as the effect of water mites’ parasitism on the number of MPs ingested by aquatic insects in two of the most polluted wastewater sites (S1 and S2) in Sohag Governorate, Egypt. The two wastewater sites receive different wastewater inputs (domestic and industrial). The results showed that the MPs abundance in surface water was higher in S2 than in S1 during the four seasons of the year, where the microplastic abundance in surface water was 2.05 ± 0.79 and 3.01 ± 0.9 particles/L in S1 and S2, respectively. Also, MPs were significantly higher in S2 in two insect taxa (Corixidae and Notonectidae) that are known to be infected by water mites. In contrast, the number of MPs was lower in S1, where water mites were absent. In addition, our results showed that adult water mites accumulated MPs. Overall, the 500–2000 µm size range was the most prevalent for both wastewater sites. Fibers were the most common MP morphotype discovered, followed by fragments. The dominant colors of MP were blue, red, and black. Furthermore, FTIR spectroscopy revealed the existence of three distinct polymers, namely polyester (PES), polypropylene (PP), and polyethylene (PE). To the best of our knowledge, this is the first study to examine the effect of water mites’ parasitism on the number of MPs ingested by aquatic organisms. However, Further research is needed to confirm our suggestion.

Reproductive parameters of four species of water mites (Acari: Hydrachnidia)

This paper presents information on the oviposition, embryonic development, egg production, and reproductive success in water mites (Hydrachnidia) under laboratory conditions. The study was carried out on four common and numerous species in Poland: Hydrodroma despiciens (lake population), Hygrobates fluviatilis (river population), Hygrobates longipalpis (lake and river populations) and Mideopsis orbicularis (lake and river populations). For H. longipalpis and M. orbicularis there were no significant differences between the number of eggs deposited by females from river and lake populations. The time of embryonic development in all species was relatively similar. In all analysed species, the mean time of embryonic development shortened with the lengthening of the day. All species were characterised by very high egg hatching success.
