Abstract (sommario):
A novel phlebovirus, Punique virus (PUNV), was discovered and isolated in 2008 from sandflies from Northern Tunisia. PUNV is now classified as a unique member of the Punique phlebovirus species within the Phlebovirus genus in the Phenuiviridae family (order bunyavirales). In this study, we aimed to investigate the transmission dynamics of PUNV in Tunisia. Sandflies were collected during two consecutive years, 2009 and 2010, by CDC light traps. In 2009, a total of 873 sandflies were collected and identified to the species level. Phlebotomus perniciosus was the most abundant species. One pool of P. perniciosus females collected in autumn contained PUNV RNA, yielding an infection rate of 0.11%. The population densities of circulating sandfly species were assessed during May–November 2010 in Northern Tunisia by using sticky traps. Phlebotomus (Larroussius) perniciosus (71.74%) was the most abundant species, followed by Phlebotumus (Larroussius) longicuspis (17.47%), and Phlebotumus (Larroussius) perfiliewi (8.82%). The densities of dominant sandfly species were found to peak in early spring and again in the autumn. In 2010, species identification was not performed, and sandflies were only discriminated on the basis of sex and collection date. Out of 249 pools, three contained PUNV RNA. Each positive pool allowed virus isolation. The three pools of female sandflies containing PUNV RNA were collected in autumn with an infection rate of 0.05%. These findings provide further evidence that P. perniciosus is the main vector of PUNV in Tunisia, and this phlebovirus is endemic in Tunisia. Our findings provided strong evidence of intensive circulation of PUNV in sandflies and hosts through a viral infection buildup process between sandfly vectors and hosts starting at the beginning of the activity of sandflies in spring to reach a maximum during the second main peak in autumn.

Abstract (sommario):
Leishmania infantum is the agent of visceral leishmaniasis in the Mediterranean basin. It is transmitted by sandflies of the subgenus Larroussius. Although Phlebotomus perniciosus is the most important vector in this area, an atypical Ph. perniciosus easily confused with Ph. longicuspis has been observed in North Africa. MALDI-TOF MS, an important tool for vector identification, has recently been applied for the identification of sandflies. Spectral databases presented in the literature, however, include only a limited number of Larroussius species. Our objective was to create an in-house database to identify Mediterranean sandflies and to evaluate the ability of MALDI-TOF MS to discriminate close species or atypical forms within the Larroussius subgenus. Field-caught specimens (n = 94) were identified morphologically as typical Ph. perniciosus (PN; n = 55), atypical Ph. perniciosus (PNA; n = 9), Ph. longicuspis (n = 9), Ph. ariasi (n = 9), Ph. mascittii (n = 3), Ph. neglectus (n = 5), Ph. perfiliewi (n = 1), Ph. similis (n = 9) and Ph. papatasi (n = 2). Identifications were confirmed by sequencing of the mtDNA CytB region and sixteen specimens were included in the in-house database. Blind assessment on 73 specimens (representing 1073 good quality spectra) showed a good agreement (98.5%) between MALDI-TOF MS and molecular identification. Discrepancies concerned confusions between Ph. perfiliewi and Ph. perniciosus. Hierarchical clustering did not allow classification of PN and PNA. The use of machine learning, however, allowed discernment between PN and PNA and between the lcus and lcx haplotypes of Ph. longicuspis (accuracy: 0.8938 with partial-least-square regression and random forest models). MALDI-TOF MS is a promising tool for the rapid and accurate identification of field-caught sandflies. The use of machine learning could allow to discriminate similar species.

Abstract (sommario):
Phlebotomus betisi was described from Malaysia and classified after its description in the subgenus Larroussius. It was the only species to have a pharyngeal armature composed of dot-like teeth and an annealed spermatheca whose head is carried by a neck in females. Males were characterized by having a style bearing five spines and a simple paramere. The study of sandflies originating from a cave in Laos enabled us to discover and describe two sympatric species close to Ph. betisi Lewis & Wharton, 1963 and new for Science: Ph. breyi Vongphayloth & Depaquit n. sp., and Ph. sinxayarami Vongphayloth & Depaquit n. sp. They were characterized morphologically, morphometrically, geomorphometrically, molecularly, and proteomically (MALDI-TOF). All approaches converged to validate the individualization of these species whose morphological differential characters lay in the two genders by the observation of the interocular suture and by the length of the last two segments of the maxillary palps. In males, the length of the genital filaments discriminates these species. Females are distinguished by the length of the ducts of the spermathecae as well as by the narrow or enlarged shape of the neck bearing their head. Lastly, the particular position of the spines of the gonostyle coupled with molecular phylogeny led us to remove these three species from the subgenus Larroussius Nizulescu, 1931 and to classify them in a new subgenus: Lewisius Depaquit & Vongphayloth n. subg.

Abstract (sommario):
This study is a part of investigations on leishmaniasis vectors which began in 1992. Sandflies were collected in different areas of Kassandra, Sithonia and Athos and in several biotopes of the Xanthi district in Thrace. A total of 811 sandflies were caught using oil-traps in peridomestic sites in the town of Neos Marmaras in 1992, and 4264 specimens were collected by CDC miniature light traps in different parts of Chalkidiki in 1993. Similarly 3465 specimens were collected in Xanthi in 1996. Eight species of sandflies were identified: Phlebotomus (Larroussius) neglectus Tonnoir 1921, P. (L.) tobbi Adler et al. 1930, P. (L.) perfiliewi Parrot 1930, P. (Paraphlebotomus) sergenti Parrot 1917, P. (Adlerius) simici Nitzulescu & Nitzulescu 1931, P. (Phlebotomus) papatasi Scopoli 1786, Sergentontomyia minuta Rondani 1843 and S. dentata Sinton 1933. The roles played in the transmission of leishmaniasis by different species of sandflies is discussed.

Abstract (sommario):
Phlebotomine sand flies are vectors of several diseases of importance for public health, including leishmaniosis, bartonellosis, and sand fly fevers. An entomological survey on blood-feeding Diptera was conducted in June–November 2020–2021 to know the diversity of insect vectors in Mallorca (Balearic Islands, Spain). Among the vectors collected, Phlebotomus (Larroussius) perfiliewi Parrot, 1930 was found being the first record of this species in Spain. Phlebotomus perfiliewi s.l. is one of the main vectors of Leishmania infantum in the Mediterranean Basin and Central Asia. The identification of this species was confirmed by both morphological features and DNA barcoding. Phylogenetic analyses showed that the specimens captured were Ph. perfiliewi s.s. (99.85–100% homologues from Italy and Algeria specimens), with a sequence divergence of 0.17%. The cytochrome c oxidase subunit I gene clearly separates the three species that make up the Ph. perfiliewi species complex. In addition, we also provide a brief discussion about their identification remarks, phylogenetic relationships, and vector status.

Abstract (sommario):
AbstractIndividual wild-caught sandflies from Iran were examined for infections of Wolbachia pipientis by targeting the major surface protein gene wsp of this intracellular α-proteobacterium. In total, 638 male and female sandflies were screened, of which 241 were found to be positive for one of three wsp haplotypes. Regardless of geographical origins and habitats, Phlebotomus (Phlebotomus) papatasi and other sandfly species were found to be infected with one common, widespread strain of A-group W. pipientis (Turk 54, GenBank accession EU780683; AY288297). In addition, a new A-group haplotype (Turk07, GenBank accession KC576916) was isolated from Phlebotomus (Paraphlebotomus) mongolensis and Phlebotomus (Pa.) caucasicus, and a new B-group haplotype (AZ2331, GenBank accession JX488735) was isolated from Phlebotomus (Larroussius) perfiliewi. Therefore, Wolbachia was found to occur in at least three of the incriminated vectors of zoonotic cutaneous leishmaniasis and zoonotic visceral leishmaniasis in different geographical regions of Iran. It may provide a new tool for the future control of leishmaniasis.

Abstract (sommario):
Abstract Sand flies (Diptera: Psychodidae) are natural vectors of Leishmania. For the initiation of sand fly experimental infections either Leishmania amastigotes or promastigotes can be used. In order to obtain comparable results, it is necessary to adjust and standardize procedures. During this study, we conducted promastigote- and amastigote-initiated infections of Leishmania infantum Nicolle, 1908 parasites in Phlebotomus (Larroussius) perniciosus Newstead, 1911 in two laboratories with different levels of biosafety protection. Protocol originally designed for a biosafety level 2 facility was modified for biosafety level 3 facility and infection parameters were compared. Particularly, specially designed plastic containers were used for blood feeding; feeders were placed outside the sand fly cage, on the top of the mesh; feeding was performed inside the climatic chamber; separation of engorged females was done in Petri dishes kept on ice; engorged females were kept in the cardboard containers until dissection. All experiments, conducted in both laboratories, resulted in fully developed late stage infections with high number of parasites and colonization of the stomodeal valve. We demonstrated that protocol originally designed for biosafety level 2 facilities can be successfully modified for other biosafety facilities, depending on the special requirements of the individual institution/laboratory.

Abstract (sommario):
SummaryIn this paper we report on the diversity and distribution of a set of non-LTR retrotransposon (RTP) reverse transcriptase (RT) sequences isolated from phlebotomine sandflies, and their potential for investigating the evolutionary histories of members of this subfamily of flies (Diptera: Psychodidae, Phlebotominae). The phlebotomine RT sequence families derived from one species were as different from each other as they were from RT sequences derived from other species. When each was used to probe Southern blots of sandfly genomic DNA they hybridized only to the species of source and, usually, to others of the same subgenus, but not to DNA from other subgenera — a hybridization pattern consistent with vertical evolution. There was considerable intraspecific variation in hybridization pattern, suggesting the RTs were part of non-LTR RTPs that are (or were recently) subject to flux in genomic position and copy number. Most of the RT families detected in phlebotomines are monophyletic with respect to previously described RTs, and all are monophyletic with RTs of the F/Jockey (Drosophila melanogaster) type of RTP. Orthologous sequences were isolated from the closely related species Phlebotomus perniciosus and P. tobbi (subgenus Larroussius), and different populations of P. perniciosus. The level of sequence divergence among these orthologous RTs, the subgeneric distribution of each RT family, and the intraspecific variation in hybridization pattern of many of them, indicate this class of sequence will provide genetic markers at the sub-generic level.

Visceral leishmaniasis (VL) caused byLeishmania donovaniis endemic in northern Ethiopia, whereP. orientalisis the most important presumed vector. This study was designed to determine the physiological age structure and the occurrence ofLeishmaniainfection in the vector of VL in Tahtay Adiyabo district, northern Ethiopia. Sand flies were collected using CDC light traps from peridomestic and agricultural fields between May 2011 and April 2012 andP. orientalisfemales were dissected for age determination and detection ofLeishmaniapromastigotes. Sand flies were also analyzed forL. donovanidetection using molecular methods. Of 1,282P. orientalisexamined for abdominal stages and age characterization, 66.2%, 28.2%, 4.1%, and 1.6% were unfed, freshly fed, half-gravid, and gravid. Parous rate in unfed females was 34.1% and 35.4% in peridomestic and agricultural fields, respectively. Out of 921P. orientalisfemales dissected, one specimen (0.1%) was found naturally infected with promastigotes. Five pools (25 females) of unfedP. orientaliswere also found with DNA ofLeishmaniaspp. In particular, a singleP. orientaliswas positive forL. donovani(0.5%). Based on this and other evidences (abundance, human blood feeding, and xenodiagnostic studies),P. orientalisis the principal vector of VL in this endemic focus.

Abstract (sommario):
Objective: In Morocco leishmaniasis represent entities of great clinical and epidemiological diversity and thus constitute a public health problem. The area of Moulay Yaâcoub, North central of Morocco. This study was conducted in all localities of the province of Moulay Yaâcoub to understand the epidemiology and spatial distribution of sandflies in this region. Nine among eleven localities of the province of Moulay Yaâcoub have never been studied and the phlebotomy fauna of the region remains unknown until now. Methods: Trapping was done using sticky traps once a month during the period of activity of sandfly from April to October. Results: A total of 3287 specimens of sandflies were collected. 8 species belonging to two genera Phlebotomus (94.3%) and Sergentomyia (5.7%). The study of sex ratio showed an advantage of males to females for all species. However, for the species S. falax, S. antennata, S. minuta we have not collected females. The highest sex ratio was determined for Ph. Perniciosus and lowest among S. dreyfussi. The results show a difference in the distribution of species between different localities. Conclusion: it was possible to distinguish two major entities; a dominant sub-genre Phlebotomus and Paraphlébotomus, responsible for the cutaneous form in the center and northwest of the province, and a sub-genre dominated Larroussius entity responsible for the visceral form the northeast of the province with a small entity in the south-eastern province. The results of this study will help undoubtedly health authorities to establish appropriate monitoring and anti-vectorial control measures.

Abstract The idea of the existence of Phlebotomus (Larroussius) neglectus (Diptera: Psychodidae) Tonnoir, 1921 in Iran and the skepticism about the existence of Phlebotomus major s.str. Annandale, 1910 had been grown recently in the country. This study reports a combined analysis of mitochondrial and ribosomal DNA target regions of P. major s.l.Annandale, 1910, specimens collected from different parts of Iran. Two different morphotypes were found among the collected samples based on the shape of the aedeagus, ventrally located hairs of the coxite, and parameral sheets. One morphotype seemed similar to P. neglectus Tonnoir 1921 or P. major krimensis Perfiliv1966 (called here MI.N.K.); the other one was similar to P. neglectus and to some extent to P. notus Artemiev & Neronov 1984 (here called MII.N.NO). Cytochrome B, elongation factor 1-alpha, and internal transcribed spacer II loci were amplified, sequenced, and characterized. High sequence homology (98–100%) was observed between P. neglectus and these morphotypes, and phylogenetic analysis was also concordant. Phlebotomus neglectus sequences available in GenBank are located as the sister group of sequences here, particularly near to morphotype MII.N.NO. Moreover, ITS2 locus provides the maximum resolution for differentiation of two morphotypes. Based on achieving results, although a strong support for the presence of P. neglectus was provided, but it is too early to say that P. major s.str. does/does not exist in Iran. This question could be resolved by studying more samples and, most importantly, by comparing the topotypes of P. neglectus and P. major s. str. if possible in the future.

Abstract (sommario):
Visceral leishmaniasis (VL; kala-azar) is one of the most important parasitic tropical diseases in Sudan and the Sudan is considered to be one of the most important foci in the world. The visceral leishmaniasis has been described in Sudan since the beginning of the twentieth century. In Sudan, VL is caused by Leishmania donovani complex: MON 18, MON 30 and MON 82 zymodemes and The proven vector is Phlebotomus (Larroussius) orientalis, in this study a survey was carried out to identify the principal vector of VL based on Leishmania infection, morphological characters and to determine some ecological aspects of the sand flies prevalent in the area . Ten species of sand flies were recorded, three Phlebotomus species and seven Sergentomyia species of these sandflies, P. rodhaini was collected only from Acacia seyal/Balanities aegyptiaca at the Island whereas S. hunti was collected from the Acacia nilotica forest only of the total collections, P. orientalis representing 3.80% (248 specimens) of the total collection and P. papatasi were 3.11% of the collection. Sand flies identification was done under a binocular microscope at 40x (magnification). The main features used for sand flies identification were the sperm theca of the female, the termination of the male and the pharyngeal and the ciboria toothed structures of both sexes. According to results of this study we recommended the following: more studies are needed in the future to determine the transmission season, and infection rates of Leishmania parasites in human and the animal host in this area. Annually Entomological surveys must be done to determine density of Sand fly Vectors and Encourage the use of personal protection tools (ITNs), repellents, and improving of houses to avoid bite of sand fly.

Abstract (sommario):
Based on nucleotide sequences, we re-identified representative samples of Phlebotomus perfiliewi originating from two different biogeographical areas of Tunisia, whose populations had previously been identified based on morphological criteria. A partial region of the mitochondrial DNA cytochrome b gene was targeted, and sandfly species was determined by analogy with DNA sequences available in the GenBank database via a BLAST analysis, taking into account the query coverage and percentage identity. The recognized species presents the most substantial homology with the analyzed sequence. The results of the molecular identification showed complete agreement with the morphological identifications, and Phlebotomus perfiliewi is genetically variable.

Abstract (sommario):
AbstractThe Oligocene and Miocene tectonic and biogeographical alterations of the peri-Mediterranean area could strongly impact the speciation processes and migrations of Mediterranean sandfly species. To understand the possible former role of this palaeobiogeographic factor on ancestral sandfly species, the potential suitability values of five Larroussius, two Paraphlebotomus and one Phlebotomus species were modelled from the Rupelian to the Tortonian stage in the Central Paratethys. The bioclimatic extrema of this sandfly species and the Coexistence Approach-based palaeoclimatic reconstructions made the basis of hypothesis testing. In the case of the Tortonian stage, a georeferenced climatic model was created. The models indicate that the suitability values could notably vary by species and periods. The monsoon-influenced humid subtropical climate of the Oligocene epoch could be less suitable for the ancestors of Mediterranean sandfly taxa than the later, drier humid subtropical climates-characterised Miocene stages. The Central Paratethys area could be less suitable for ancestors of the extant Paraphlebotomus, and Phlebotomus in the Miocene epoch compared to Larroussius species. It may indicate that the Central Paratethys formed a barrier against the east-to-west migration of the ancestors of Phlebotomus and Paraphlebotomus species. In contrast, Larroussius species could prefer the Miocene climate of the Central Paratethys. In the Tortonian stage, mainly the coastal areas of the sea could be colonised by sandflies. These results indicate that the coasts of the Central Paratethys should be not only considered as a potential former migration route but could be a part of the speciation area of Larroussius sandflies.

Abstract (sommario):
Abstract Northern Morocco is endemic for cutaneous and visceral leishmaniasis. Our entomological investigations aim to evaluate the risk of Leishmania transmission by determining the species composition, the density, and seasonal fluctuation of sand fly populations in endemic and nonendemic areas of leishmaniasis in Tetouan province (North-Western Morocco). Using Sticky-paper traps, 8,370 specimens were collected between May and November 2015 in two localities: peri-urban area of Tetouan city, where leishmaniasis is endemic and that of the Oued Laou village where no cases of leishmaniasis have been recorded. Six sand fly species were identified. The genus Phebotomus was represented by five species: Phlebotomus ariasi, Phlebotomus. longicuspis, Phlebotomus perniciosus, Phlebotomus kazeruni, and Phlebotomus sergenti, while the genus Sergentomyia was represented by only one species Sergentomyia minuta. Phlebotomus perniciosus was dominant in the nonendemic area (47%) while Phlebotomus sergenti was dominant in the endemic area (51%). The spatio-temporal distribution of sand fly populations is discussed according to biotic and abiotic variables. Seasonal fluctuation in sand fly density showed a bimodal pattern for the subgenus Larroussius and a unimodal pattern for the subgenus Paraphlebotomus in Tetouan city. But, in Oued Laou village, a unimodal density distribution for species of the Larroussius subgenus and a bimodal seasonal distribution for species of the subgenus Paraphlebotomus were identified. We affirm the coexistence, in the study area, of vectors of both cutaneous and visceral leishmaniasis, namely P. ariasi, P. longicuspis and P. perniciosus vectors of Leishmania infantum and P. sergenti vector of L. tropica. However, the geographic distribution, the specific abundance, and the activity reveal significant differences between endemic and nonendemic areas in the region.

Abstract (sommario):
Phlebotomine sandflies are known to transmit leishmaniases, bacteria and viruses that affect humans and animals in many countries worldwide. These sandfly-borne viruses are mainly the Phlebovirus, the Vesiculovirus and the Orbivirus. Some of these viruses are associated with outbreaks or human cases in the Mediterranean Europe. In this paper, the viruses transmitted by Phlebotomine sandflies in Europe (Toscana virus, Sicilian virus, sandfly fever Naples virus) are reviewed and their medical importance, geographical distribution, epidemiology and potential spreading discussed. Data on vertebrate reservoirs is sparse for sandfly fever viruses. The factor currently known to limit the spread of diseases is mainly the distribution areas of potential vectors. The distribution areas of the disease may not be restricted to the areas where they have been recorded but could be as wide as those of their vectors, that is to say Larroussius and P. papatasi mainly but not exclusively. Consequently, field work in form of viral isolation from sandflies and possible reservoirs as well as laboratory work to establish vectorial competence of colonised sandflies need to be encouraged in a near future, and epidemiological surveillance should be undertaken throughout the European Union.
