A report on the mosquitoes of mainland Åland, southwestern Finland and revised list of Finnish mosquitoes
Abstract
To successfully implement surveillance or control strategies for mosquitoes, up‐to‐date knowledge of regional species composition is vital. The last report regarding mosquitoes (Diptera: Culicidae) in the Åland archipelago, southwestern Finland listed 19 species (Utrio, 1979). To determine the current species diversity, one collection trip was made to mainland Åland in 2015 and three in 2016. Mosquitoes (n = 3286) were collected as both adult and immature life stages from 88 collections within 29 1‐km2 areas. Fifteen of the 19 previously reported species were obtained, leaving the current status of fou...

Culex torrentium mosquitoes from Germany are negative for Wolbachia
Abstract
Wolbachia (Rickettsiales: Anaplasmataceae) infects a wide range of arthropods, including several mosquito species. The bacterium is known to induce a plethora of phenotypes in its host, examples being the reproductive phenotype cytoplasmic incompatibility or resistance against infection with arboviruses. The latter is especially relevant when assessing the vector competence of mosquito species for emerging arboviruses. Thus, knowledge of Wolbachia infection status is important for the assessment of vector competence.
To facilitate Wolbachia screening in mosquito populations, a quantitative polymerase chain reactio...

Behavioural and electrophysiological responses of Triatoma dimidiata nymphs to conspecific faecal volatiles
Abstract
The behavioural and electrophysiological (electroantennography) responses of the first two instars of Triatoma dimidiata (Hemiptera: Reduviidae) Latreille to fresh and dry faecal headspace volatile extracts from fifth instar conspecific nymphs and synthetic compounds were analysed in this study. Recently emerged nymphs (3–5 days) aggregated around filter paper impregnated with dry faeces and around filter paper impregnated with extracts from both fresh and dry faeces. Older first instars (10–15 days) and second instars aggregated around filter paper impregnated with fresh and dry faeces, and their respecti...

Impact of climate change on vector transmission of Trypanosoma cruzi (Chagas, 1909) in North America
Abstract
Climate change can influence the geographical range of the ecological niche of pathogens by altering biotic interactions with vectors and reservoirs. The distributions of 20 epidemiologically important triatomine species in North America were modelled, comparing the genetic algorithm for rule‐set prediction (GARP) and maximum entropy (MaxEnt), with or without topographical variables. Potential shifts in transmission niche for Trypanosoma cruzi (Trypanosomatida: Trypanosomatidae) (Chagas, 1909) were analysed for 2050 and 2070 in Representative Concentration Pathway (RCP) 4.5 and RCP 8.5. There were no significant...

Revealing potential bridge vectors for BTV and SBV: a study on Culicoides blood feeding preferences in natural ecosystems in Spain
Abstract
Several species of Culicoides (Diptera: Ceratopogonidae) are vectors of pathogens, such as the bluetongue (BTV) and Schmallenberg (SBV) viruses, which cause important diseases in domestic and wild ruminants. As wild ruminants can contribute to overwintering and epizootics of both diseases, knowledge of the host‐feeding behaviour of Culicoides in natural ecosystems is important to better understand their epidemiology. Blood‐engorged Culicoides females trapped in natural areas inhabited by different wild ruminant species were genetically analysed to identify host species. The origin of bloodmeals was identified ...

Ecological and physiological thermal niches to understand distribution of Chagas disease vectors in Latin America
Abstract
In order to assess how triatomines (Hemiptera, Reduviidae), Chagas disease vectors, are distributed through Latin America, we analysed the relationship between the ecological niche and the limits of the physiological thermal niche in seven species of triatomines. We combined two methodological approaches: species distribution models, and physiological tolerances. First, we modelled the ecological niche and identified the most important abiotic factor for their distribution. Then, thermal tolerance limits were analysed by measuring maximum and minimum critical temperatures, upper lethal temperature, and ‘chill‐...

Prevalence and distribution of Borrelia and Babesia species in ticks feeding on dogs in the U.K.
In this study, ticks were collected from dogs by veterinarians participating in a U.K.‐wide tick surveillance programme.
The ticks were subjected to polymerase chain reaction and sequence analysis for detection of Borrelia burgdorferi s.l. and Babesia spp. pathogens, the distributions of which were mapped.
DNA of B. burgdorferi s.l. and Babesia spp. was detected in 2.0% and 1.5% of the ticks analysed, respectively. The results map a widespread distribution of the two pathogens in the U.K. (Source: Medical and Veterinary Entomology)
