We report on a study of the ecology of Aedes detritus on the Dee estuary for the 9 years from 2011 to 2019. We describe the annual, seasonal and geographical distribution of the adult and immature mosquitoes, with peaks in late Spring and early Autumn, and how these are explained by the characteristics of the small breeding pools on the upper levels of the marshes, and their filling by high spring tides. We demonstrate that pool excavation to enlarge and deepen pools greatly reduces breeding. From these studies, we developed an online weekly forecast of the local biting nuisance, and report on the temporal and geographical distribution of the bite reports produced by the public in response.

Ibaňez-Justicia SP - 1 EP - 10 KW - Aedes KW - dispersal KW - Europe KW - invasive mosquitoes KW - pathway KW - surveillance KW - vector-borne diseases AB - Abstract: In the last decades, Aedes invasive mosquito species (AIMs) have arrived in Europe from overseas, introduced via different pathways. Several species such as Aedes albopictus, Ae. japonicus and Ae. koreicus were introduced, built populations, and expanded their distribution into new regions. The introduction and establishment of AIMs in Europe is a risk to public health, due to the ability of these mosquitoes to transmit diverse pathogens of vector-borne diseases. The objective of this manuscript is to review knowledge of pathways associated with the introduction and dispersal of AIMs in Europe. The identification of pathways for introduction of AIMs is critical to decide on surveillance strategies needed to reduce the risk and control future introductions. Four main routes are identified and discussed: the passive transport of AIMs via (1) the trade of used tyres, (2) the trade of Lucky bamboo plant cuttings, (3) vehicles (traffic by road, airplanes, and sea), as well as (4) the active natural dispersal of AIMs. We conclude that the trade of used tyres remains the main pathway for long distance transportation and introduction of AIMs into and within Europe. Furthermore, passive transport by road in ground vehicles (e.g. car, truck) represents the major driving force for dispersion from already established populations.

New challenges for the administration and citizens of Cordoba JF - Journal of the European Mosquito Control Association Y1 - 2019 A1 - Obregon, Rafael A1 - Flores, Enrique A1 - Jordano, Diego SP - 28 EP - 33 KW - Aedes albopictus KW - Asian tiger mosquito KW - Cordoba KW - Diptera KW - Invasion KW - invasive species KW - Spain AB - Abstract: The first record of the presence of the invasive Asian tiger mosquito Aedes albopictus in the province of Cordoba is presented. Adults, larvae, pupae and exuviae have been located at different points of housing estates in the northeastern part of the city. One possible origin is the coast around Malaga, much frequented by the citizens of Cordoba. Its detection has been possible due to the programme of monitoring, surveillance and control of hematophagous Dipterans, initiated in 2016 by our research group (Terrestrial Ecology, RNM232) in collaboration with the Sanitation Public Company of Cordoba (SADECO). The arrival of the tiger mosquito in Cordoba is a relevant issue due to its implications for welfare and public health. In addition to the discomfort and injuries caused by its bites, it is a competent vector of non-endemic arboviruses such as Chikungunya fever, Dengue fever and Zika. Therefore, with the information gathered by our group, the SADECO technicians acted appropriately, with the focus being to control it and try to prevent it from spreading and causing public health problems. However, given the large flow of people between Cordoba and the coast around Malaga, a vacation area very popular among the people of Cordoba, it is foreseeable that the inadvertent transport of mosquitoes by car to Cordoba will generate new outbreaks. Therefore, it will be important to continue with the programme of early detection of this invasive species through coordinated work involving researchers from the University of Cordoba, SADECO technicians, and the local and provincial administrations, with the collaboration of neighbourhood associations and the population in general. The information presented in this article is relevant due to its implications for welfare and public health.

We here synthesise published records in an updated distribution chart. The western Palaearctic region is divided into 5 areas and 75 geographical units, the latter mainly considered on a country basis or on a geographical basis (e.g. islands). The total number of species accounts for 145. The status of each species for a defined geographic unit is given according to five categories: ‘Present native’, ‘Present introduced’, ‘Uncertain for presence or absence’, ‘Absent extinct’ and ‘Absent never observed’. Relevant references are given per country in the annex. Journal of the European Mosquito Control Association 37: 1-28, 2019.

A1 - Wahlqvist, Pernilla A1 - Lundström, Jan O. SP - 17 EP - 22 KW - Europe KW - floodplains KW - mosquito diversity KW - mosquito species richness KW - River Dalälven KW - Sweden AB - Abstract: The floodplains of the River Dalälven, Central Sweden, have previously been known for enormous abundance of mosquitoes causing unbearable nuisance, but since mosquito control measures by Biologisk Myggkontroll (BMK) commenced in 2002, the area’s beautiful landscape and high biodiversity can be more appreciated. The floodplains are the central part of the UNESCO Nedre Dalälven River Landscape Biosphere Reserve as well as the location of various protected areas. The rich biodiversity also includes mosquitoes, although these insects are rarely considered in the study of biodiversity. We analysed mosquito data collected by the BMK surveillance program from 2001 until 2017 for species richness and assemblages of the mosquito fauna in the floodplains of the River Dalälven, and the nearby Creeks Vretaån and Kilsån. The mosquito species richness of the Nedre Dalälven River Landscape included 30 species in the present study, and three to eight species could potentially be added according to other studies, which then includes more than 70% of all known mosquito species in Sweden. The location of the floodplains at the Limes Norrlandicus, the border between southern and northern vegetation zones, is reflected in the mosquito fauna that includes species commonly found in Northern Sweden as well as more southern species. The mosquito species richness of the region is similar to the species richness observed in other floodplain areas in Central and Southern Europe. Hydrological conditions of the Lake basins of the River Dalälven floodplains varied from frequent flooding with high amplitude to almost no flooding. As expected, the hydrological variations were reflected in the mosquito assemblages, with high prevalence of floodwater mosquitoes in the flood-prone areas and more homogenous assemblages in the areas less subject to flooding. In conclusion, the River Dalälven floodplain area is considered a mosquito diversity hot-spot for Sweden and for Europe.

The emergence and invasion of exotic vector species increases the likelihood that additional vector-borne diseases may appear in regions that have not encountered them previously. In the last few years, different emerging pathogens affecting humans, livestock and wildlife were detected in mosquitoes in the Eastern European region; moreover, several invasive mosquito species were recorded in the area. The importance of particular mosquito species for the transmission of vector-borne pathogens is strongly determined by several factors such as their feeding behaviour. However, there is a huge knowledge gap regarding the ecological background of host use by mosquitoes and their capacity to act as vectors. Derived from a transboundary mosquito surveillance programme, a total of 84 engorged mosquitoes were subjected to PCR-based blood meal identification analysis and screened for Plasmodium species. The majority of tested mosquitoes were Aedes vexans and Culex pipiens, in addition to an exotic species Aedes koreicus, which was detected last summer for the first time in the vicinity of Balkans region. Hereby, we provide the first explicit data regarding the feeding behaviour of this exotic species in Europe. The human origin of blood-meal may highlight the possible medical importance of the species and its important role in mosquito nuisance. Aedes vexans mosquitoes exhibited mostly zoophilic behaviour compared to Cx. pipiens, which was found to be primarily anthropophilic and secondarily ornithophilic, along with amphibian host preference. We detected Plasmodium relictum in five Cx. pipiens, which had fed on humans. This study provides additional insight into the ectothermic host preference of Cx. pipiens in nature and highlights the human and veterinary health importance of these species. In addition, these results provide novel insight for the feeding patterns of the investigated mosquitoes.

In 1990, this mosquito was recorded for the first time in Italy (Port of Genova) and in about 20 years it has become established throughout the whole country. In this paper, we report for the first time the presence of Ae. albopictus on three small islands in the Tyrrhenian Sea, namely Giglio, Ventotene and Ustica. Most probably, the maritime transport of goods and tourists during the summer is the major entry route of this mosquito species.

It has also been described to occur over large parts of Germany, but reports are scarce and date back several decades. The last time Ae. refiki was documented for Germany was in 1980 when the species was found in the central northern part of the country. During larval sampling activities, Ae. refiki was rediscovered at two locations in the German federal state of Thuringia in spring 2016. The collection sites, method of species identification and species characteristics are described and discussed.

A control technique consisting of the use of pieces of metallic copper has been repeatedly proposed as a control solution for mosquito larvae in these pots. Although theoretically promising, this technique has not been used at an operative level, as there has been a lack of information on the best adapted copper formulation as well as on the mosquito larval population dynamics. The present study was planned to characterise the spatial larval distribution of Aedes albopictus in flower pots in a wall-niche burial system, and to test the cost-effectiveness of metallic copper application. We found that the preliminary distribution of larvae and pupae in the cemetery was not related to height from the ground but varied between buildings. During the 8 weeks of the trial, application of copper in the form of thin electric wire resulted in a season-accumulated reduction of 90.95% in the production of larvae and 97.06% of the pupae. Application costs and social interactions are discussed as other control methodologies would be more cost-efficient in this specific context. Copper application could be suitable for domestic environments, if application is performed adequately.

Using next generation sequencing (NGS), this method can be further developed into metabarcoding processes that allow the simultaneous identification of several species from a mixed sample. We created a database of COI sequences of 27 mosquito species collected in Sweden, and combined our data with 27 additional sequences from GenBank to cover the taxa recently documented in Sweden and to include possible invasive taxa. Comparisons show that COI metabarcoding reliably identifies 41 of 54 species and the remainder to species group. Using three independent primer pairs along the COI gene, we further developed this barcoding approach to simultaneously identify Swedish mosquitoes in communities using NGS and quantify relative abundance of each mosquito species in the sample, using bioinformatics methods. We tested the accuracy of the metabarcoding method using communities assembled from morphologically identified mosquitoes, revealing 80% positive identification rate and the estimates of population structure which reflects the input sample. We conclude that metabarcoding is useful as a high throughput identification technique and for the quantification of species.

The number of emerging adults, the time of emergence and the size of the adult bodies were recorded and compared. The number of adults that emerge under conditions of food abundance was found to be significantly higher than under food shortage. When food was lacking more males than females emerged and there was no significant difference in their body sizes, while under food abundance females were larger than males. Both males and females with abundant food were on average bigger than under food shortage. There was no difference in the time of adult emergence in the two different food conditions.

There has been a growing interest in the establishment and spread of invasive aedine mosquito species but also in understanding native mosquitoes. Following concerns regarding black and white-striped mosquitoes biting aggressively during the day, survey visits were organised by the Joint Services Health Unit on the Kryos river at the village of St. Mavra, Limassol district, Cyprus. Adult mosquitoes collected either during human landing catches in June 2015 or adults that emerged in the laboratory from water collected from tree holes in January 2016, were identified as Aedes (Stegomyia) cretinus. During the same period (June 2015), Ae. cretinus adults were also collected by the Public Health authorities of the Republic of Cyprus from a local residence at Avdellero village, Larnaca district. Aedes cretinus is a species with limited distribution and close resemblance to the Asian tiger mosquito Aedes (Stegomyia) albopictus. Information on mosquito species and their respective geographic distribution is fundamental for the goal of reducing the impact of emerging vector-borne viral zoonoses in Europe and targeting control for vector and nuisance species. Our study highlights the need for educational and raising awareness programmes regarding insects of medical importance as well as the importance of collaboration and networking between the relevant authorities.

Similar to other container-breeding mosquitoes, this primarily mammophilic species could be a vector for several pathogens of medical or veterinary importance. We here report for the first time a laboratory colonisation of Ae. geniculatus. Eggs and larvae were collected from forest edges in the area around Zürich, Switzerland. The colony could be established by maintaining adults at room temperature in a large cage where mating occurred. Females took blood meals through a pig intestine membrane in a restricted space. After embryo development for 8 – 14 weeks at 10 °C, ‘hatching in installments’ was induced. Our established colony of Ae. geniculatus, now in its sixth generation, facilitates future studies on basic ecology and physiology of this species and its vector capacity traits.

The presence of these blood-feeding insects is well reported in many areas of the world; however, the distribution in anthropogenic zones has not been studied so far across Spain. In order to gather information on this entomofauna in urban environments, adult stages were collected using an automatic entomological aspirator during the summer season in street lamps of a public park located in the city of Vitoria-Gasteiz (Basque Country, Spain). A total of 333 culicids from four species were collected in a two-year sampling period: Culex pipiens (91.3%), Culiseta longiareolata (8.1%), Culiseta litorea (0.3%) and Culex hortensis hortensis (0.3%). Moreover, 225 Culicoides specimens belonging to six different species were trapped: Culicoides punctatus (61.3 %), Culicoides obsoletus s.s. (16.8%), Culicoides duddingstoni (13.3%), Culicoides kibunensis (6.2%), Culicoides dewulfi (1.7%) and Culicoides clastrieri (0.4%). The first data of Culicoides species distribution in urban areas and the first record of C. litorea are recorded for the Basque Country region.

The effects of five different and widely used mosquito control agents (monomolecular film [MMF], diflubenzuron, Bacillus thuringiensis var. israelensis [Bti], Bacillus sphaericus [Bs] and temephos) on Culex pipiens L. oviposition were studied in both field and laboratory conditions. Half of the standard application dosages were used for all five control agents. Results were evaluated weekly for three weeks. All tested mosquito populations (Serik, Avariz, Slab and field) showed different degrees of oviposition preferences on experimental and control cups and pools. Culex pipiens L. tended to lay a lower number of eggs for tests groups than the control group throughout the whole test duration. Oviposition preferences of all Cx. pipiens decreased in the second week (except temephos both Avariz and field test, MMF both control and field test, Bs both Serik and control) and increased again in the third week. The repellent effects of MMF and temephos on oviposition were found to be higher than for the other larvicides. Mosquito species use different chemical cues for finding an ovipositional site. Therefore MMF and temephos may help in future control efforts, albeit less than the diflubenzuron, Bti and Bs on mosquitoes and mosquito-borne disease epidemics.

Aedes (Stegomya) albopictus is an invasive mosquito native to tropical areas in Southeast Asia. It is an important vector of several pathogens of public and veterinary health significance. In 2004 this mosquito was recorded for the first time in Spain (Catalonia) and detected in Majorca (Balearic Islands) in 2012. In this paper, we report for the first time the presence of Ae. albopictus on the island of Ibiza (‘Eivissa’, Balearic Islands, Spain). The high volume of goods arriving by maritime transport and the increase of commercial trade and visitors during recent years have been identified as the most probable entry routes for the species on the Island.

We used DNA sequencing of the COI gene for molecular identification of damaged specimens, and observed two individuals from 2013 with aberrant COI-sequences. These two specimens were collected on separate occasions, and represent COI haplotypes that differ from Aedes (Finlaya) geniculatus by 2.0 - 2.4%, and from Aedes (Finlaya) echinus by 4.4 - 5.0%. Further analysis revealed a similarity to an Aedes (Finlaya) specimen from Macedonia, with these three specimens forming a genetic cluster. Our findings are discussed in the context of the three Aedes (Finlaya) species presently reported in Europe, and the potential introduction into Germany by road traffic.

Abstract: After a report of mosquito nuisance and collection of live Culex quinquefasciatus mosquitoes on board of a passenger aircraft from Africa to Amsterdam, a mosquito surveillance was carried out in 38 cabins of passenger aircraft from overseas airports immediately after landing at Amsterdam Schiphol airport, the Netherlands (2010 and 2011). Live mosquitoes were collected in 10 aeroplanes, belonging to the species Culex quinquefasciatus (n=9), Culex antennatus (n=2), and Aedes mcintoshi (n=1). All mosquitoes were collected in aeroplanes that came from airports located in Africa. Disinsection is discussed. Journal of the European Mosquito Control Association 32: 17-21, 2014

Abstract: Six gel-and five water-transported Dracaena braunii shipments originating from the South coast of China were screened for exotic mosquito species during a surveillance project on exotic vectors in Belgium. In November 2013, a live Aedes (Stegomyia) albopictus larva was detected in a gel substrate. This is the first direct evidence of the importation of Ae. albopictus on gel-transported Lucky bamboo. It also confirms that the importation risk of Ae. albopictus by transport of ornamental bamboo plants remains. In addition to the registration of appropriate biocides, a structured and permanent surveillance programme is needed in Belgium to allow for the early detection of invasive mosquito species and the timely implementation of control measures.

Abstract: In January 2013, a female mosquito collected during the week 18th-25th July 2012 in Lelystad (The Netherlands) during routine national vector surveillance was morphologically identified and genetically confirmed as the Asian bush mosquito, Aedes japonicus japonicus. In order to assess the extent of the infestation area, subsequent extensive mosquito surveillance in the surrounding area during 2013 consisted of visual inspection of potential habitats and adult trapping in increasing radially around the location of the initial finding. This surveillance confirmed the existence of a widely established population of Ae. j. japonicus in the municipality of Lelystad. Despite this detection, it was decided not to implement any mosquito control measures for two reasons: this would require large scale biocidal treatment and community participation in order to be effective, and this species is not a confirmed vector of disease agents in the field. As an alternative, it was decided that community information would be provided to enable management measures such as larval habitat source reduction.

Abstract: Mass-occurrence of floodwater mosquitoes, mainly Aedes sticticus, in the River Dalälven floodplains in central Sweden has caused public health issues and economic losses for many decades. In the summer of 2000, the problem escalated and the Biological Mosquito Control project was initiated with the aim of reducing mosquito nuisance. Larviciding, based on Bacillus thuringiensis israelensis (Bti), was chosen as the optimal method. However, high abundance of blood-seeking floodwater mosquitoes after Bti-treatments on some occasions raised questions about the effectiveness of the treatments. This study evaluated the effect of Bti-larviciding on abundance of larval and adult floodwater mosquitoes in four selected study areas, each represented by a CDC-trap site and a 5 km radius. The four areas differed with respect to their mosquito control history and the coverage of larval habitats with Bti-larviciding. The Bti-treatments provided a significant reduction of mosquito larval abundance, and normally 100% reduction was achieved. Thus, high abundance of blood-seeking mosquitoes could not be explained by insufficient larval control by Bti. However, a significant negative correlation was found between high numbers of blood-seeking floodwater mosquitoes and the coverage of larval habitats with Bti-larviciding within 5 km around the trap site. Consistently low numbers of mosquitoes (less than 1000 per trap/night) were only found in the two areas with high treatment coverage of larval habitats (97-100%). Evaluating the mosquito control efficiency showed that larval habitat coverage of at least about 95% is required in order to accomplish consistent low floodwater mosquito numbers. The conclusion from this analysis is that the coverage of larval habitats with Bti-larviciding in parts of the River Dalälven floodplains has to increase in order to guarantee an improvement of the public health problems caused by Aedes sticticus and other floodwater mosquitoes to both humans and animals in the region.

With few exceptions, systematic large-scale field studies on the mosquito fauna have not been performed in Germany for decades. Thus, up-to-date data on the occurrence and distribution of the indigenous mosquito species are lacking. In particular, there is no information on whether once rare and restrictively occurring species are still present. Here we describe the recent finding of four Culiseta species rarely encountered in Germany: Cs. alaskaensis, Cs. glaphyroptera and Cs. ochroptera, which have always been considered endemic but were seldom found and last reported a long time ago, and Cs. longiareolata, which has recently been found to have established in southern Germany.

Surveillance of the actual distribution of mosquito species in Northern Europe is fundamental for evaluating risk for emerging pathogens, and for research on potential vectors. The Swedish mosquito fauna composition and geographic distribution, originally described by Professor Christine Dahl in the 1970´s, included 43 species. We have compiled the information published from 1978 to 2012, and our own surveillance data from 2001 to 2013, and compared this with the species list and geographic distribution provided in “Taxonomy and geographic distribution of Swedish Culicidae” by Dahl (1977). New species detected during these 36 years were Culiseta (Culicella) ochroptera (Peus, 1935) published 1984, Aedes (Aedes) rossicus Dolbeskin, Goritzkaja & Mitrofanova, 1930 published 1986, Anopheles (Anopheles) beklemishevi published 1986, Aedes (Ochlerotatus) euedes (Howard, Dyar & Knab, 1912) published 2001, Aedes (Ochlerotatus) nigrinus (Eckstein, 1918) first recorded in 2012, and Anopheles (Anopheles) algeriensis Theobald, 1903, first recorded in 2013. We provide maps with the distribution by province for each species, including historic information up until 1977, and new records from 1978 to 2013, showing the similarities and differences between the old and the new records. Important findings in recent years include the wide distribution of the Sindbis virus enzootic vector Culex (Culex) torrentium Martinii, 1925, and the more limited distribution of the potential West Nile virus vector Culex (Culex) pipiens Linnaeus, 1758. The updated list of mosquito species in Sweden now includes 49 species.

During a West Nile virus surveillance programme, Culiseta longiareolata (Macquart, 1838) was discovered for the first time in Austria. Two larvae and one female imago were collected from an artificial water storage container in the wine-growing village of Gamlitz (province of Styria) on July 12, 2012 at 450 m.a.s.l., 46°4058,2´N, 15°3151,4´E. Additional specimens of Cs. longiareolata were found on September 8, 2012, when numerous larvae were detected in used car tyres about 160 km westward, in the region of Finkenstein (province of Carinthia). A third site containing larvae of Cs. longiareolata was discovered on October 10, 2012, near Althofen about 60 km northeast of the Finkenstein location. Previously, in May 2012, the latter two sites were negative for Cs. longiareolata. In autumn 2013 Cs. longiareolata was reconfirmed in Carinthia and the first record detected for Slovenia with larvae collected from a rain barrel in a location approximately 6 km north-northeast of the city of Maribor, on September 1, 2013 at 288 m.a.s.l., 46°3959,8´N, 15°3942,2´E. It is proposed that Cs. longiareolata was not passively introduced along a major transportation route, but has either actively invaded from neighbouring Italy and Slovenia into the south of Austria within the last few decades and/or has remained undetected owing to its cryptic occurrence on account of its belated activity at the end of summer and during autumn.

Anopheles algeriensis, a mosquito species primarily found in the Mediterranean region and susceptible to Plasmodium spp., is one of seven Anopheles species previously reported from Germany. However, the last record dates back to 1958. Whether it was really absent since then or whether this is just a sign of neglected mosquito studies over several decades is unclear. The present study is part of a nationwide mosquito mapping project launched in 2011. We describe larval dip collections of An. algeriensis in 2013 from the inland salt meadow “Brenner Moor”, located in Schleswig-Holstein, northern Germany, which represents the most northerly of all German An. algeriensis collection sites known so far. Despite several mosquito mapping projects carried out in Germany over recent years, An. algeriensis has not been detected within the last 55 years. Therefore this species appears to be extremely rare or at least rurally localised. Hence, it remains a very low risk vector in terms of autochthonous malaria transmission in Germany.

The Asian tiger mosquito, Aedes (Stegomyia) albopictus is an invasive mosquito species of major concern to public health because of its vector role in transmission of several pathogens of human and animal health importance. This species was first detected in Europe (Albania) in 1979. Since then, at least eighteen additional European countries have reported its presence. In 2004, this mosquito was detected for the first time in Spain (Catalonia). Here we report, for the first time, the presence and establishment of Ae. albopictus on the island of Majorca (Balearic Islands, Spain). However, the introduction pathway of this species in Majorca has not yet been identified. The prompt surveillance programme implemented according to the guidelines of the European Centre for Disease Prevention and Control (ECDC) rapidly permitted a determination of the expansion of Ae. albopictus on the island. The information obtained from this study might be useful to plan mosquito control measures avoiding the spread of this vector species to the entire island.

This is the first report on species composition and seasonal human biting activity of mosquitoes in the city of Chisinau, Moldova. In total 3,255 adult mosquitoes were collected in eight recreational areas. Sampling occurred by means of two methods: human landing collection and net-catches from vegetation. Altogether, 22 mosquito species in nine genera were found, representing 55% of the species diversity in Moldova. Seventeen anthropophilic species with different seasonal patterns of biting activity were found in human landing collections. The most frequently captured species was Aedimorphus vexans (N = 1,514; 46.5%) followed by Ochlerotatus annulipes (N = 403; 12.4%), Dahliana geniculata (N = 330; 10.1%), Culex modestus (N = 312; 9.6%), Coquillettidia richiardii (N = 144; 4.4%) and Oc. riparius (N = 117; 3.6%). Eight of the species are the known vectors of West Nile virus in Europe; four of them are the natural vectors of Dirofilaria. Journal of the European Mosquito Control Association 31: 1-7, 2013
