“…Arrenurus is the genus most reported to parasitize mosquitoes, evidence of its flexibility regarding host specificity [ 33 ]. Despite this, recent findings suggest that these mites prefer Culex species [ 34 ]. Aside from reducing host fitness by piercing their exoskeleton to feed on hemolymph, each host–parasite association has its own characteristics, which are determined mainly by the size of the partners, intrinsic defence mechanisms and environmental conditions [ 35 ].…”

The systematics of many groups of organisms has been based on the adult stage. Morphological transformations that occur during development from the embryonic to the adult stage make it difficult (or impossible) to identify a juvenile (larval) stage in some species. Hydrachnidia (Acari, Actinotrichida, which inhabit mainly continental waters) are characterized by three main active stages—larval, deutonymph and adult—with intermediate dormant stages. Deutonymphs and adults may be identified through diagnostic morphological characters. Larvae that have not been tracked directly from a gravid female are difficult to identify to the species level. In this work, we compared the morphology of five water mite larvae and obtained the molecular sequences of that found on a pupa of the common mosquito Culex (Culex) pipiens with the sequences of 51 adults diagnosed as Arrenurus species and identified the undescribed larvae as Arrenurus (Micruracarus) novus. Further corroborating this finding, adult A. novus was found thriving in the same mosquito habitat. We established the identity of adult and deutonymph A. novus by morphology and by correlating COI and cytB sequences of the water mites at the larval, deutonymph and adult (both male and female) life stages in a particular case of ‘reverse taxonomy’. In addition, we constructed the Arrenuridae phylogeny based on mitochondrial DNA, which supports the idea that three Arrenurus subgenera are 'natural': Arrenurus, Megaluracarus and Micruracarus, and the somewhat arbitrary distinction of the species assigned to the subgenus Truncaturus.

“…The epidemiology of this infectious condition is dependent on the frequency and the proficiency of the contacts within the human host and the anopheles mosquitoes which is explained as how many of the mosquitoes infections resulting from an infected human host and the frequency of infections of uninfected mosquito that occurred from the bite of the infected host [15,16]. Yet exposure to the vector within hospitals is obvious and seemed normal in the Tamale Metropolis.…”

Mosquitoes are considered the main agents for the transmission of several deadly diseases including malaria with controlling and preventing exposure to this vector being one of the main strategies for malaria control and prevention in Ghana. Exposure to this vector by patients/caretakers and hospital staff within wards of hospitals is a public health threat and should be a public health concern. The study assessed exposure to mosquitoes, the determinants of exposure to the vector by patients and hospital staff within wards of hospitals. A descriptive cross-sectional survey involving a mixed-method research design was conducted among 313 patients and nurses/midwives within the selected hospitals and 5 members of hospital management including ward in-charges and medical superintendents. A structured questionnaire was used for the quantitative data and an interview guide for the qualitative data collection. The data were analyzed using SPSS version 22.0 for the quantitative data and NVivo version 10.2, and content analyses for the qualitative data. Majority of the respondents (69.3%) were females and almost all the respondents were exposed to mosquitoes. About 98.4% experienced the presence of mosquitoes, 95.2% reported yes to have bitten by mosquitoes, 69.6% were unable to sleep due to mosquitoes the night preceding the study interview and 69.3% were highly exposed. Access to health information, state of nets of windows and doors of the ward, cracks on the walls of the ward, broken ceilings on the ward and grown bushes around the ward were observed to be significantly related to exposure to mosquitoes. Exposure to mosquitoes within the health facilities is obvious and considered normal as there is no or little effort towards preventing such a public health threat. All hospital stakeholders should work to curb this menace, the national malaria control program should consider hospitals as a priority area as far as controlling and preventing malaria is concerned.

“…Although the exact nature of the host–parasite relationship between mosquitoes and mites is uncertain, water mites exhibit predatory and parasitic behaviors on larval and adult stage mosquitoes, respectively ( Werblow et al. 2015 ; Atwa, Bilgrami, and Al-Saggaf 2017 ; Vasquez et al. 2020 ).…”

Meta-transcriptomics reveals potential virus transfer between Aedes communis mosquitoes and their parasitic water mites

et al. 2022

Arthropods harbor a largely undocumented diversity of RNA viruses. Some arthropods, like mosquitoes, can transmit viruses to vertebrates, but are themselves parasitized by other arthropod species, such as mites. Very little is known about the viruses of these ectoparasites and how they move through the host-parasite relationship. To address this, we determined the virome of both mosquitoes and the mites that feed on them. The mosquito Aedes communis is an abundant and widely distributed species in Sweden, in northern Europe. These dipterans are commonly parasitized by water mite larvae (Trombidiformes: Mideopsidae) that are hypothesized to impose negative selection pressures on the mosquito by reducing fitness. In turn, viruses are dual-host agents in the mosquito-mite interaction. We determined the RNA virus diversity of mite-free and mite-detached mosquitoes, as well as in their parasitic mites, using meta-transcriptomic sequencing. Our results revealed an extensive RNA virus diversity in both mites and mosquitoes, including 37 putative novel RNA viruses that cover a wide taxonomic range. Notably, a high proportion of viruses (20/37) were shared between mites and mosquitoes, while a limited number of viruses were present in a single host. Comparisons of virus composition and abundance suggest potential virus transfer between mosquitoes and mites during their symbiotic interaction. These findings shed light on virome diversity and ecology in the context of arthropod host-parasite-virus relationships.
