“…This decrease in population numbers of S. erythrocephalum during July, August, and September has been reported in other countries of Central and North Europe [24, 33–36]. Bardin [32] reported that S. erythrocephalum produced discomfort in France from spring through October. Thus, further studies are needed to define the spatial and temporal dynamics of S. erythrocephalum in Spain .…”

“…May and June were the most suitable months for the sampling of S. erythrocephalum in this area. Bardin [32] pointed out that discomfort due to S. erythrocephalum species begins in May and increases during June and July in southern France. In September 2015, few S. erythrocephalum females (1–2 females were caught using HLC at dusk each day) were observed flying, and low numbers of larvae and pupae were found at the breeding sites.…”

Background Simulium (Boophthora) erythrocephalum (De Geer, 1776) is one of the blackfly species responsible for major public health problems in Europe. Blackfly outbreaks of this species are becoming more frequent, threatening public health in Spain. In the present study, bionomic parameters of S. erythrocephalum in northeastern Spain were estimated.Methods Simulium erythrocephalum was collected from May through June 2015 in Zaragoza, Spain, using the human-landing-collection (HLC) method. Daily pattern of total and parous landing activity was estimated, as was the gonotrophic cycle (GC) length and survivorship (S) rate, using time series analysis.ResultsHost-seeking females of S. erythrocephalum showed a bimodal human-landing activity pattern, with a minor and major peak at dawn and dusk, respectively; there was a significant negative association between human daily landing rate and temperature (P = 0.003) and solar radiation (P < 0.001). Overall, a daily landing rate (DLR) of 34 lands/person/day was estimated. Series of sequential data analysis on parity showed the highest significant (P < 0.001) correlation indices (r = 0.45 and r = 0.39 for raw and filtered data) for a 2-day time lag, indicating that the GC length corresponded to 2 days. Daily survivorship and parity rate were 0.85 and 0.72, respectively.Conclusions Simulium erythrocephalum was confirmed as a nuisance species in Zaragoza, using the HLC method for the first time in Spain. The data offer insights into the ecology of S. erythrocephalum, which can improve management strategies of this pest in Spain.

“…In Europe, there are several countries that have suffered and/or suffer blackfly outbreaks that regularly threaten public health, for example: United Kingdom [26,27], Serbia [8,24,28,29], France [30,31], Hungary [32], Italy [33], Turkey [34] and Scandinavian countries [1], among others. As far as we know, although there are no published European studies based on a temporal analysis of blackfly bite medical consultations, several authors have quantified the number of people who required health care during a blackfly outbreak.…”

“…In addition to that, the highest insect bite records were registered at the same period [8]. Bardin [31] explained that the nuisances of S. erythrocephalum in the south of France started in May decreasing during June and July but continued till October. Other authors have pointed out previously a decreasing in the adult population of this species during the months of July, August and September [8,[35][36][37][38].…”

Background: Animals and people in many Spanish regions are increasingly being affected by blackfly bites in the last decade. Because of blackflies, the city of Zaragoza has become in recent years a paradigm of discomfort in Europe, with thousands of citizens affected. The OMI-AP system (Stacks, Barcelona, Spain) implemented by the Government of Aragón, a software that manages the electronic medical history of all patients, has been evaluated in order to document the increase of insect bite recorded by the primary care consultations in Zaragoza after the first outbreak of blackflies occurred in 2011. Methods: An observational, ecological and longitudinal study of insect bites recorded at the primary care consultations was carried out in primary care during the period 2009–2015. Results: The incidence of medical consultations by insect bites in Basic Health Areas (BHA) near to rivers is higher than the furthest BHA. Rural BHA are more affected by insect bites than the urban ones. The increase of medical assistance due to insect bites in Zaragoza since 2011 is correlated with the blackflies bites. Conclusions: This tool was very useful to describe the initial stage of this public health problem. It could be used for guiding public health responses in terms of surveillance and management of this pest.

The biology of Simulium erythrocephalum and S. chelevini (Diptera, Simuliidae): Morpho-logical, ecological and molecular data

The subgenus Boophthora is a typical Palearctic taxon, which includes only 6 species, among them. Simulium erythrocephalum has a transpalearctic distribution. In Europe, Adler notes only the species S. erythrocephalum, and Yankovsky – two species S. (Boophthora) erythrocephalum and S. (Boophthora) chelevini. According to morphological characteristics, these species differ in their life stages. We have studied the development of S. erythrocephalum and S. chelevini from three rivers of Volyn region, Ukraine (Styr, Chornoguzka, Putylivka) from 2017 to 2019. We used the EPPO PM7 / 129 standard. Collected samples, 615-bp fragments of the COI gene were sequenced from five individuals of S. erythrocephalum and five individuals of S. chelevini and compared with four samples of S. erythrocephalum from the GenBank. We obtained the nucleotide sequence of S. chelevini. All of the S. erythrocephalum samples from Ukraine had 692 bases, the S. erythrocephalum samples from Armenia had 673 bases. S. erythrocephalum and S. chelevini did not have any intraspecific variations. These intraspecific variations were not larger than the interspecific variations. It has been proved that the populations of S. erythrocephalum and S. chelevini from medium and small rivers of Volyn do not differ in biological, behavioural and genetic characteristics. Comparison of S. erythrocephalum and S. chelevini life stages showed clear differences in 20 morphological features, which are probably manifestations of phenotypic variability. Comparison of species with data from the GenBank from Spain and Armenia on the mitochondrial cytochrome c oxidase subunit I (COI) gene confirmed the opinion that S. erythrocephalum and S. chelevini are one species. On the phylogenetic tree, the data are not grouped, there is no clear separation of the clades. Bootstrap values are 95–100%, which may indicate a significant similarity of all studied samples and the lack of isolation of individual morphotypes from Volyn, Spain and Armenia. To finally confirm the taxonomic position of these two species, additional research is needed covering more individuals from different parts of Europe and analysis of more genes.
