“…Expansion of the distribution area during the period from 1986 to 2010 (segment C in Figure 1) can be ascertained based on our results and the results of other researchers [22, 28]. Due to lack of detailed data on Anopheles distribution in Scandinavia [44], the borders of its distribution area in this region were determined based on data provided by Ramsdale & Snow [45]. The southeastern borders reported by White (1978) [15] have been confirmed by recent studies.…”

BackgroundThe burden of malaria infection in the modern world remains significant. Specific changes in the relative proportions of malaria vector mosquitoes, Maculipennis Complex species, in the south of Western Siberia over the past 25 years of the 20th century have attracted wide attention as an indicator of their dynamic geographical distribution. In Eurasia, studies of fluctuations in the borders of areas occupied by sibling species of this complex, as well as their relative proportions in the areas where they are sympatric are epidemiologically important.MethodsSpecies identity and chromosomal polymorphisms within each population were defined by cytogenetic analysis of polytene chromosomes of third- and fourth-instar larvae and adult females of Anopheles mosquitoes collected over the period from 1973 to 2012. A total of 37 Anopheles samples (3,757 specimens) from the Ukraine, European Russia and the Urals were studied. To identify An. messeae s.l. cryptic species A and B, polymerase chain reaction and restriction fragment length polymorphisms of the second internal transcribed spacer rRNA genes sequences (ITS2 PCR-RFLP) were used.ResultsAn. maculipennis s.s. is expanding to the northeast at a speed of approximately 30 km per year. In 2008 or 2009, this species appeared in the Southern Urals. The emergence of An. maculipennis in this region was accompanied by a decrease in the proportions of An. messeae A and An. beklemishevi and by an increase in the proportion of An. messeae B within An. messeae s.l. It is highly likely that the southwestern border of An. beklemishevi distribution area could shift in the same direction as expanding area of An. maculipennis.ConclusionsThe geographical distribution of the Palaearctic mosquito species of the Maculipennis Complex is undergoing a gradual shift. Changes detected in the species distribution can be considered as a component of the biocenotic process triggered by global warming. Both the warming itself and consequent expansion of An. maculipennis s.s. to the northeast, followed by changes in the species composition of Anopheles as well as their relative proportions and fluctuations in the species areas, exacerbate the epidemiology of malaria infection in Eurasia.

“…However, An. beklemishevi which is not considered an important vector of malaria and so far has only been demonstrated to occur in Scandinavia and Russia (Korvenkontio et al 1979;Stegniy 1982;Jaenson et al 1986) was not involved in the assay. In the meantime we could analyse the ITS2 rDNA of An.…”

Integration of Anopheles beklemishevi (Diptera: Culicidae) in a PCR assay diagnostic for palaearctic Anopheles maculipennis sibling species

A few years ago a PCR-based assay for a quick and reliable identification of six palaearctic sibling species of the Anopheles maculipennis complex was presented making use of differences in the nucleotide sequence of the ITS2 ribosomal mosquito DNA. An. beklemishevi, which is distributed in Scandinavia and Russia only, has now been integrated into this test after analysis of its ITS2 region which turned out to be much longer than those of the other sibling species. Three oligonucleotides putatively specific for An. beklemishevi were constructed and tested in combination with a universal genus-specific primer for the amplification of an An. beklemishevi-specific ITS2 DNA-fragment. Two of the three oligos generated accurate and specific PCR products, even when used in a multiplex PCR together with the specific primers for the other six sibling species. Cross-hybridization of the primers to heterologous culicid DNA was never observed. The amplicons that identify An. beklemishevi consist of 554 and 735 bp, respectively, and are easily distinguished from those specific for the other sibling species after gel electrophoresis.

“…Following these early works, extensive efforts were made to elucidate all Palaearctic members of the Maculipennis Group, which comprise what is now known as the Maculipennis Complex ( sensu White, 1976, 1978; Harbach, 1994). Studies included egg morphology (Falleroni, 1926, 1932; Corradetti, 1934; de Buck & Swellengrebel, 1934a; Hackett & Lewis, 1935; Korvenkontio et al ., 1979), hybridization experiments (de Buck & Swellengrebel, 1934b; Kitzmiller et al ., 1967), ecology studies (van Thiel, 1927; de Buck & Swellengrebel, 1934b; Hackett & Missiroli, 1935), larval chaetotaxy (La Face, 1931; Diemer, 1935; Bates, 1939; Buonomini, 1940; Işfan, 1952; Suzzoni‐Blatger & Sevin, 1981; Boccolini et al ., 1986; Suzzoni‐Blatger et al ., 1990; Deruaz et al ., 1991), pupal chaetotaxy (Diemer, 1935; Işfan, 1952), adult morphology (de Buck et al ., 1933; Diemer, 1935; Ungureanu & Shute, 1947), chromosomes (Frizzi, 1947, 1952, 1953; Kitzmiller et al ., 1967; Stegnii & Kabanova, 1976; Stegnii, 1976; White, 1978), zymotaxonomy (Korvenkontio et al ., 1979; Bullini et al ., 1980; Bullini & Coluzzi, 1982; Jaenson et al ., 1986; Cianchi et al ., 1987; Suzzoni‐Blatger et al ., 1990), cuticular hydrocarbons (Phillips et al ., 1990) and, most recently, DNA sequences (Marinucci et al ., 1999; Proft et al ., 1999; Linton et al ., 2001b, 2002a,b,c).

“…Progeny broods, which result in link‐reared adults of both sexes with associated larval and pupal exuviae, are an invaluable resource for mosquito systematics research, allowing both molecular and morphological data to be gathered from the same genetic stock. Traditionally, eggs have been used to identify mosquitoes of the Maculipennis Complex (Hackett & Lewis, 1935; Missiroli, Hackett & Martini in Hackett, 1937; Weyer, 1942; Angelucci, 1955; Gutsevich et al ., 1974; Korvenkontio et al ., 1979; White, 1978; Pichot & Deruaz, 1981; Jaenson et al ., 1986; Jetten & Takken, 1994); however, it has been shown that intraspecific variation in egg morphology can result in incorrect identifications (Guy et al ., 1976a; Jaenson et al ., 1986; Alten et al ., 2000; Linton et al ., 2002b). Previous studies have shown that the pupal stage of Anopheles often bear characters of use in distinguishing closely related species, including members of sibling species complexes (Harrison & Peyton, 1984).…”

Abstract. Adults and larvae of Anopheles maculipennis Meigen were collected in Greece in May and June 2001. Larvae and the progeny of wild-caught females were individually reared to obtain samples of all life stages for integrated morphological and molecular study. Specimens were identified on the basis of egg morphology and correlation of their ITS2 rDNA sequences with those in GenBank. The adult, pupal, larval (fourth-instar) and egg stages are described, and all stages except the egg are illustrated. Partial sequence data are provided for the mitochondrial cytochrome c oxidase I (COI) gene and complete sequences for the nuclear ITS2 region. Additionally, the bionomics and distribution of the species are reviewed, and its taxonomy and systematics are discussed. This study provides the first fully integrated morphological and molecular assessment of An. maculipennis, the nominotypical member of the Maculipennis Complex, and the type species of genus Anopheles, and serves as a foundation for further studies of the complex and subfamily Anophelinae.
