Population genetic structure and phylogenetic analysis of Anopheles hyrcanus (Diptera: Culicidae) inferred from DNA sequences of nuclear ITS2 and the mitochondrial COI gene in the northern part of Iran. BMC Infect Dis 2024; 24:724. [PMID: 39044181 PMCID: PMC11264359 DOI: 10.1186/s12879-024-09626-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Accepted: 07/16/2024] [Indexed: 07/25/2024] Open
Abstract
BACKGROUND The Anopheles hyrcanus group is distributed throughout the Oriental and Palaearctic regions and can transmit diseases such as malaria, Japanese encephalitis virus, and filariasis. This investigation marks the inaugural comprehensive study to undertake a phylogenetic analysis of the constituents of this malaria vector group in the northeastern region of Iran, juxtaposed with documented occurrences from different areas within Iran and worldwide. METHODS Mosquitoes were collected using various methods from nine different locations in Golestan province from April to December 2023. The collected mosquitoes were identified morphologically using valid taxonomic keys. DNA was isolated using the Sambio™ Kit. COI and ITS2 primers were designed using Oligo7 and GeneRunner. PCR and purification were performed with the Qiagen kit. Subsequently, sequencing was carried out at the Mehr Mam GENE Center using an Applied Biosystems 3730XL sequencer. The nucleotide sequences were then analyzed and aligned with GenBank data using BioEdit. Kimura 2-parameter was Utilized for base substitutions. DNA models were selected based on AIC and BIC criteria. Bayesian and Maximum Likelihood trees were constructed, along with a haplotype network. Molecular diversity statistics computed using DnaSP software. RESULTS In this study, a total of 819 adult mosquitoes were collected. An. hyrcanus was the second most abundant species, predominantly found in Kalaleh and Turkman counties. The sequenced and edited COI and ITS2 sequences were deposited in GenBank under specific accession numbers. Phylogenetic analyses using ML, BI, and NJ methods confirmed a monophyletic lineage for An. hyrcanus with strong support. Molecular analysis of Iranian An. hyrcanus found 11 diverse haplotypes, with the COI gene displaying low diversity. The ITS2 gene revealed two clades - one associating with Iran, Europe, and Asia; the other originating from southwestern Iran. The haplotype network showed two main groups - one from southwest Iran and the other from north Iran. Iran exhibited six distinct haplotypes, while Turkey showcased the highest diversity. CONCLUSIONS An. hyrcanus in southwestern Iran exhibits a distinct haplogroup, suggesting possible subspecies differentiation. Additional studies are required to validate this phenomenon.

Abstract
Despite the fact that mosquito-borne infections have considerable consequences for public health in Saudi Arabia, there is neither a thorough review of the species that occur in the country nor updated keys for the identification of the adult females. In this study, species accounts are given for 49 Saudi Arabian mosquito species, as well as Aedes albopictus (Skuse), which is not recorded in Saudi Arabia, but is medically important and is found in some countries of the Middle East and North Africa. Taxonomic notes provide additional information for certain taxa and/or aid their identification.

Razygraev AV. Catalase enzymatic activity in adult mosquitoes (Diptera: Culicidae): taxonomic distribution of the continuous trait suggests its relevance for phylogeny research. Zootaxa 2023; 5339:159-176. [PMID: 38221060 DOI: 10.11646/zootaxa.5339.2.3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Indexed: 01/16/2024]
Abstract
Molecular research based on gene sequence analysis and performed for decades, in general, supported morphology-based groupings of the species within the family Culicidae, but phylogenetic relationships between some genera and tribes remained uncertain for a long time. Interspecific differences in catalase, an antioxidant enzyme important for maintaining prolonged lifespan and reproduction, have not been studied extensively by estimating enzymatic activity levels. Here, catalase enzymatic activity was assayed in extracts of male mosquitoes belonging to 10 species of the subfamily Culicinae, including species from tribes of disputable phylogeny. Three species of Chaoboridae (nearest outgroup taxon) and mosquitoes from the subfamily Anophelinae (one species complex) were also added to the study. At least in Culicinae, immature adult males (less than one day after emergence) have distinctly elevated specific activity of catalase; therefore, only mature males of all species were used for the comparative study. As a result, significant differences in catalase activity were revealed between tribes, genera and particular species. Among culicids, the genera Coquillettidia and Culiseta were found to include the species with the highest and relatively high catalase activity, which is consistent with the affinity of the tribes Mansoniini and Culisetini to each other. Within Ochlerotatus, extremely low catalase activity in Oc. hexodontus suggests the more distant position of this species from Oc. cantans (Meigen) and Oc. communis (de Geer) than the positions of the latter two species from each other. Additional study of catalase activity in overwintering females of the genus Culex revealed significantly higher enzyme activity in Cx. torrentium in comparison with Cx. pipiens, which supports their quite distant positions from each other within the genus. Considering the distribution of catalase activity within the tree obtained, the preliminary outcome is that Culiseta retains the elevated level of catalase activity that was lost during the early separation of Anopheles and subsequent separation of Culex and Aedes/Ochlerotatus after Anopheles from their common branch with Culiseta/Coquillettidia. Overall, the use of taxonomic distribution of catalase activity levels appears to be effective for resolving disputed events of mosquito phylogeny.

Abstract
Beginning about 80 years ago, the recognition of morphological varieties of mosquitoes was gradually replaced by the recognition of subspecies. As an examination of revisionary and detailed taxonomic studies of mosquitoes clearly shows, subspecies are untenable concepts which have been synonymized with nominotypical forms or recognized as distinct species. Thus, from our perspective, subspecies is not a functional or practical taxonomic rank. Consequently, in this study we critically assessed the taxonomic status of the 120 nominal taxa distinguished as subspecies before now to determine whether they should be recognized as separate species or synonymous names. As a result, 96 subspecies are formally elevated to specific rank, 22 are relegated to synonymy with nominotypical forms, one is considered a nomen dubium, one a species inquirenda and the names of four nominal species regarded as synonyms are revalidated. The subspecies and their new status are listed in a conspectus. The revalidated species include Anopheles argentinus (Brèthes, 1912), from synonymy with An. pseudopunctipennis Theobald, 1901c; An. peruvianus Tamayo, 1907, from synonymy with An. pseudopunctipennis as nomen dubium; Culex major Edwards, 1935, from synonymy with Cx. annulioris consimilis Newstead, 1907; and Trichoprosopon trichorryes (Dyar & Knab, 1907), from synonymy with Tr. compressum Lutz, 1905. Additionally, the type locality of Anopheles sergentii Theobald, 1907 is restricted to El Outaya, Biskra Province, Algeria. A complete list of species to be retained, added to or removed from the Encyclopedia of Life, with a few corrections, is provided.

The aquatic macrophyte Salvinia molesta mitigates herbicides (glyphosate and aminomethylphosphonic acid) effects to aquatic invertebrates. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:12348-12361. [PMID: 36109480 DOI: 10.1007/s11356-022-23012-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Accepted: 09/09/2022] [Indexed: 06/15/2023]
Abstract
We evaluated the individual and combined effects of different environmentally representative concentrations of glyphosate (0, 25, 50, 75, and 100 µg l-1) and aminomethylphosphonic acid (AMPA; 0, 12.5, 25, 37.5, and 50 µg l-1) on the physiology of Aedes aegypti larvae, as well as the capacity of the aquatic macrophyte Salvinia molesta to attenuate those compounds' toxicological effects. Larvae of Ae. aegypti (between the third and fourth larval stages) were exposed for 48 h to glyphosate and/or AMPA in the presence or absence of S. molesta. Glyphosate and AMPA induced sublethal responses in Ae. aegypti larvae during acute exposures. Plants removed up to 49% of the glyphosate and 25% of AMPA from the water, resulting in the exposure of larvae to lower concentration of those compounds in relation to media without plants. As a result, lesser effects of glyphosate and/or AMPA were observed on larval acetylcholinesterase, P450 reductase, superoxide dismutase, mitochondrial electron transport chain enzymes, respiration rates, and lipid peroxidation. In addition to evidence of deleterious effects by media contamination with glyphosate and AMPA on aquatic invertebrates, our results attest to the ability of S. molesta plants to mitigate the toxicological impacts of those contaminants.
