Distribution of Anopheles daciae and other Anopheles maculipennis complex species in Serbia

Improvement of morphological and molecular identification methods allows the detection of new species of mosquitoes. The mosquito fauna of Croatia currently includes 52 species, belonging to eight genera, including Anopheles (12 species), Aedes (24 species), Coquillettidia (one species), Culex (seven species), Culiseta (six species), Orthopodomyia (one species), and Uranotaenia (one species). This is an updated checklist, which includes five new species found in Croatian mosquito fauna. Two of these are invasive mosquito species, Aedes albopictus (Skuse, 1895) and Aedes japonicus (Theobald 1901), which are spreading across Europe and Croatia. The other three species, Culex laticinctus (Edwards 1913), Culex torrentium (Martini 1925), and Anopheles daciae (Linton, Nicolescu & Harbach 2004) are autochthonous species which haven't been recorded so far. Since there are several more invasive species spreading across Europe, we assume that this is not the final list.

“…The most common approach to the assessment of possible malaria re-introduction is the analysis of distribution of vectors and changes in their bionomics [68,69]. Climatic and social factors are often added [70,71], but they are first considered from the point of view of their possible effect on vectors.…”

Background: Between 1999 and 2008 Russia experienced a flare-up of transmission of vivax malaria following its massive importation with more than 500 autochthonous cases in European Russia, the Moscow region being the most affected. The outbreak waned soon after a decrease in importation in mid-2000s and strengthening the control measures. Compared with other post-eradication epidemics in Europe this one was unprecedented by its extension and duration. Methods: The aim of this study is to identify geographical determinants of transmission. The degree of favourability of climate for vivax malaria was assessed by measuring the sum of effective temperatures and duration of season of effective infectivity using data from 22 weather stations. For geospatial analysis, the locations of each of 405 autochthonous cases detected in Moscow region have been ascertained. A MaxEnt method was used for modelling the territorial differentiation of Moscow region according to the suitability of infection re-emergence based on the statistically valid relationships between the distribution of autochthonous cases and environmental and climatic factors. Results: In 1999-2004, in the beginning of the outbreak, meteorological conditions were extremely favourable for malaria in 1999, 2001 and 2002, especially within the borders of the city of Moscow and its immediate surroundings. The greatest number of cases occurred at the northwestern periphery of the city and in the adjoining rural areas. A significant role was played by rural construction activities attracting migrant labour, vegetation density and landscape division. A cutoff altitude of 200 m was observed, though the factor of altitude did not play a significant role at lower altitudes. Most likely, the urban heat island additionally amplified malaria re-introduction. Conclusion: The malariogenic potential in relation to vivax malaria was high in Moscow region, albeit heterogeneous. It is in Moscow that the most favourable conditions exist for vivax malaria re-introduction in the case of a renewed importation. This recent event of large-scale re-introduction of vivax malaria in a temperate area can serve as a case study for further research.

Background A dominant malaria vector, Anopheles messeae, is a highly polymorphic species with wide distribution throughout Eurasia. Five highly polymorphic inversions associated with the geographical distribution of the species have been reported. A sister species, An. daciae, was described and discriminated from An. messeae based on five fixed nucleotide substitutions in the internal transcribed spacer 2 (ITS2) of ribosomal DNA. However, the levels of genomic divergence, chromosomal variation, and ecological differentiation between these two cryptic species remain unexplored. Results In this study, we sequenced ITS2 and analyzed the inversion frequencies of 289 Anopheles larvae specimens collected from three locations in the Moscow region. We identified a high abundance of both An. messeae and An. daciae in all three locations. Five individual genomes for each species of An. messeae and An. daciae from one location were sequenced. Our study confirmed five previously described nucleotide substitutions in the ITS2 of An. messeae. However, we found that the ITS2 sequence in An. daciae was heterogenic in three of the five positions. Fixed nucleotide differences between An. messeae and An. daciae were found only in the last two positions. One mosquito was identified as a hybrid between An. messeae and An. daciae based on heterogeneous substitutions in all five positions. Although, the genomic sequence comparison demonstrated genome-wide divergence between the two species, which is especially pronounced on the X chromosome, an ADMIXTURE cluster analysis demonstrated the presence of two admixed individuals suggesting ongoing hybridization. Cytogenetic analysis demonstrated that An. messeae and An. daciae significantly differ from each other by their frequency of polymorphic inversions. Inversion X1 was fixed in An. messeae but was polymorphic in all An. daciae populations. The frequency of polymorphic autosomal inversions was higher in An. messeae than in An. daciae. The species composition was different among the studied locations suggesting species-specific ecological preferences. Conclusions Our study demonstrated that An. messeae and An. daciae represent closely related cryptic species with incomplete reproductive isolation that are able to maintain genomic differentiation in sympatry despite ongoing genetic introgression. The X chromosome plays an important role in the reproductive isolation between the species.
