“…Other genera (Aedes, Culex, Culiseta, Haemagogus, and Ochlerotatus) can also serve as vectors of disease agents, but not human malaria (Harbach, 2008). This study was aimed at sampling and identifying the malaria vector species using molecular biological technique i.e., polymerase chain reaction (PCR) in Gusau township.…”

There about 460 Anopheles species recognized, over 100 can transmit human malaria but only 30–40 commonly transmit parasites of the genus Plasmodium, which cause malaria. Anopheles gambiae is the principal vector of the most dangerous malaria parasite species in Africa, which is Plasmodium falciparum. Anopheles gambiae are a complex consisting of eight morphologically indistinguishable species and each of the members of the complex having unique biology, ecology and behaviour and should be studied and differentiated. The research objective was to identify the species of malaria vector in Gusau township Nigeria using molecular biological technique to know the exact malaria vector. Knowledge of the exact malaria vector in a given environment enables formulating a carefully designed tailor-made vector control measure. Indoor and outdoor mosquito samples were collected from selected areas in five wards of Gusau township using standard collection methods, for a period of twelve months. The samples were identified using polymerase chain reaction (PCR) technique and the result showed Anopheles gambiae in all sites of sample collection. It is therefore recommended that integrated malaria vector control should be adopted in the mosquito control programme because Anopheles gambiae is rugged and can be difficult to control and/or eradicate because of the emerging insecticide resistance and its close association with human host.

“…The species is native to Africa, but it is currently found throughout tropical and subtropical regions of the globe, and its distribution is expected to further expand in response to accelerating urbanization, connectivity, and climate change [ 1 ]. Two distinct subspecies of Aedes aegypti (that may even be considered distinct species [ 2 ]) were described by early taxonomists based on morphological and ecological differences [ 3 ] that were later associated with genetic variation [ 4 ]. Aedes aegypti formosus ( Aaf ) is a dark-colored, generalist subspecies found exclusively in sub-Saharan Africa that breeds both in forest and urban habitats and blood feeds on a variety of vertebrate hosts.…”

African populations of the mosquito Aedes aegypti are usually considered less susceptible to infection by human-pathogenic flaviviruses than globally invasive populations found outside Africa. Although this contrast has been well documented for Zika virus (ZIKV), it is unclear to what extent it is true for dengue virus (DENV), the most prevalent flavivirus of humans. Addressing this question is complicated by substantial genetic diversity among DENV strains, most notably in the form of four genetic types (DENV1 to DENV4), that can lead to genetically specific interactions with mosquito populations. Here, we carried out a survey of DENV susceptibility using a panel of seven field-derived Ae. aegypti colonies from across the African range of the species and a colony from Guadeloupe, French West Indies as non-African reference. We found considerable variation in the ability of African Ae. aegypti populations to acquire and replicate a panel of six DENV strains spanning the four DENV types. Although African Ae. aegypti populations were generally less susceptible than the reference non-African population from Guadeloupe, in several instances some African populations were equally or more susceptible than the Guadeloupe population. Moreover, the relative level of susceptibility between African mosquito populations depended on the DENV strain, indicating genetically specific interactions. We conclude that unlike ZIKV susceptibility, there is no clear-cut dichotomy in DENV susceptibility between African and non-African Ae. aegypti. DENV susceptibility of African Ae. aegypti populations is highly heterogeneous and largely governed by the specific pairing of mosquito population and DENV strain.

“…Following the recent update in Culicidae nomenclature, there are no longer subspecies in mosquito classification. Culex pipiens pallens has been elevated to species status and is now referred to as Culex pallens 11 . Culex pipiens is recognized for having two ecological forms ( Culex pipiens f. pipiens and Culex pipiens f. molestus Forskal) 8 – 10 .…”

Two members of the Culex pipiens subgroup, Culex pallens and Culex pipiens f. molestus, are known to occur in the Republic of Korea (ROK). These species exhibit morphologically similar features and are challenging to distinguish below the species level. Therefore, this study utilized wing geometric morphometrics (GM) on the right wing of the Culex pipiens subgroup, alongside sequencing of the cytochrome c oxidase subunit I (COI) region. Mosquitoes were collected from 11 locations between June and October (2020–2022) to minimize regional and seasonal variations. Additionally, Culex pipiens f. pipiens, which is not native to the ROK, was included in the analysis. Culex tritaeniorhynchus, Aedes albopictus, and Anopheles sinensis, the primary vectors in the ROK, were used as outgroups for comparison. All three taxa in the Culex pipiens subgroup could be identified with an 82.4%–97.0% accuracy using GM. However, a comparison of the COI regions of the Culex pipiens subgroup revealed no clear differences between the taxa. These data can be used for accurate identification, contributing to effective mosquito control, in addition to providing a foundation for evolutionary and ecological studies on wing shape differences.
