Full textAbstract:
Hoverflies (Diptera: Syrphidae) are among the most important pollinators, although they attract less attention than bees. They are usually thought to be rather opportunistic flower visitors, although previous studied demonstrated that they show colour preferences and their nectar feeding is affected by morphological constraints related to flower morphology. Despite the growing appreciation of hoverflies and other non-bee insects as pollinators, there is a lack of community-wide studies of flower visitation by syrphids. The aim of this paper is to provide a detailed analysis of flower visitation patterns in a species rich community of syrphids in a Central European grassland and to evaluate how species traits shape the structure of the plant-hoverfly flower visitation network. We found that different species varied in the level of specialisation, and while some species visited a similar spectre of flowers, others partitioned resources more strongly. There was a consistent difference in both specialisation and flower preferences between three syrphid subfamilies. Eristalinae and Pipizinae were more specialised than Syrphinae. Trait-based analyses showed that relative flower visitation (i) increased with plant height, but most strongly in Eristalinae; (ii) increased with inflorescence size in small species from all three subfamilies, but was independent of inflorescence size in large species of Eristalinae and Syrphinae; and (iii) depended on flower colour, but in a subfamily-specific way. Eristalinae showed the strongest flower colour preferences for white flowers, Pipizinae visited mostly white and yellow flowers, while Syrphinae were less affected by flower colour. Exploration of the structure of the plant-hoverfly flower visitation network showed that the network was both modular and nested. We also found that there were almost no differences in specialisation and relative visitation frequency between males and females. Overall, we showed that flower visitation in syrphids was affected by phylogenetic relatedness, body size of syrphids and several plant traits.

AbstractThe balsam twig aphid, Mindarus abietinus Koch (Hemiptera: Aphididae), is one of the most important pests of balsam fir (Abies balsamea (Linnaeus) Miller; Pinaceae) grown as Christmas trees in eastern North America. Aphid feeding on the current-year shoots results in needle distortion and shoots stunting, which reduces the aesthetic value of balsam fir trees and can have substantial economic impact. Syrphidae (Diptera) fly predators attacking this aphid are poorly known. We identified four species attacking the balsam twig aphid. Syrphus torvus Osten Sacken (Diptera: Syrphidae) was the most abundant species followed by Eupeodes lapponicus (Zetterstedt) (Diptera: Syrphidae) and Eupeodes americanus (Wiedemann) (Diptera: Syrphidae). We described the seasonal natural history of the two most abundant syrphids feeding on this aphid and we studied their synchrony with their prey. Syrphid larval density on balsam fir shoots increased rapidly and closely followed density of the balsam twig aphid. We also reported heavy parasitism of syrphid pupae by two Hymenoptera on tree foliage but lower parasitism on pupae in the soil under trees. Several cases of multiple parasitism and hyperparasitism were observed in syrphid pupae under trees. Abundance of predaceous syrphid species was higher in untreated balsam fir plantations compared with treated plantations. More research is needed to understand the role and the impact of these predators on balsam twig aphid population dynamics.

Full textAbstract:
Aphidivorous hoverflies (Diptera: Syrphidae) at field boundaries and woodland edges in an agricultural landscape The aim of this study was to assess the occurrence and structure of the populations and communities of hoverflies (Diptera: Syrphidae) in particular types of midfield thickets (field boundaries and forest islands) characteristic of the lower Vistula valley. The investigation was carried out in 1998-2001. The midfield thickets were situated in an agricultural area. Syrphids were caught in yellow Moericke traps and with an entomological net. In the agricultural landscape the forest islands were visited by the highest percentage of aphidophagous syrphid species. Such midfield thickets (margins of forest islands) - habitats with a stable and diverse vegetation - can provide an attractive food resource for syrphids. Moreover, they offer hoverflies favourable conditions for shelter and, probably, development. Such habitats are thus key aspects of comprehensive crop protection.

Full textAbstract:
In this study, 18 mitochondrial genomes (mitogenomes) of Syrphidae were sequenced. These mitogenomes ranged from 15,648 to 16,405 bp and contained 37 genes that were similar to those from other Syrphidae species. Most protein-coding genes (PCGs) started with a standard ATN codon and ended with TAA/G. All transfer RNAs (tRNAs) could be folded into the cloverleaf secondary structure except tRNA-Ser (AGN), which lacks a dihydrouridine arm. The secondary structures of ribosomal RNAs (rRNAs) were predicted. Six domains (III is absent in arthropods) and 44 helices were included in the 16S rRNA, and three domains and 24 helices were included in the 12S rRNA. We found three conserved fragments in all syrphid mitogenomes. Phylogenetic analyses were performed based on the nucleotide data of 13 PCGs and two rRNAs from 76 Muscomorpha and three outgroup species. In results the paraphyly of Aschiza and Schizophora were supported, the Acalyptratae was also paraphyletic but the relationships of its superfamilies were difficult to determine, the monophyly of Calyptratea was supported with the relationships of Oestroidea and Muscoidea need to be further reconsidered. Within Syrphidae the monophyly of family level was supported, the Syrphinae were clustered into one branch, while the paraphyly of Eristalinae was still well supported.

Despite the species richness of hoverflies (Diptera: Syrphidae) world-wide (about 6,200 species) and their role as agents for controlling plant pests, their significance as pollinators, and as bioindicators of site quality, hoverfly fauna of Saudi Arabia is poorly known. In exploring the biodiversity of Diptera in southwest Saudi Arabia a survey of the hoverfly fauna of Jazan, Asir, Najran and Al-Baha was performed mainly using Malaise traps, sweep nets and light traps from 2011 to 2014. Forty known species of Syrphidae were identified and recorded in this study, 19 of them new to Saudi Arabia. This makes the total number of Syrphidae species recorded in Saudi Arabia (including one species recorded by others) is 41. In addition, three taxa belonging to the genera Eumerus Meigen, Orthonevra Macquart, and Paragus Latreille that could not be identified safely to species level because there were no adequate identification keys or males were missing in the collected material. A key to the genera of Syrphidae occurring in Saudi Arabia is provided. The fauna of Syrphidae recorded in this study consists much more of Afrotropical zoogeographical elements than Palaearctic ones. A complete checklist of Syrphidae of Saudi Arabia is provided. Biological data, where known, and world-wide distribution of the studied taxa are provided. This paper is published with the purpose of assisting biogeographical, biological or ecological studies on syrphids in Saudi Arabia.

Redeterminacijom publikovanog i determinacijom novog materijala iz podfamilije Syrphinae na području Srbije su zabeležene 134 vrste iz 25 rodova. Sedam vrsta (Chrysotoxum orthostylus Vujić, in prep., Chrysotoxum aff. festivum, Chrysotoxum aff. vernale, Dasysyrphus laskai Doczkal & Ståhls, in prep., Melanostoma aff. mellinum, Paragus rarus Vujić et al., in prep. i Xanthogramma citrofasciatum B Doczkal, in prep.) su nove za nauku i njihovi opisi se nalaze u pripremi. 14 vrsta su nove za faunu Balkanskog poluostrva, dok su 39 nove za faunu Srbije (uključujući i one koje su nove za Balkan).Unutar vrste Chrysotoxum festivum uočena su dva fenotipa „svetli“ i „tamni“ koji se jasno razlikuju na osnovu niza morfoloških karaktera (širina lica, širina crne trake na licu, poprašenost čela, boja dlaka na mezonotumu i skutelumu, širina oznaka na T2 i T3) kao i na osnovu veličine i oblika krila. Usled jasne divergencije pomenutih fenotipova kao i njihove simpatrije u pitanju su odvojene vrste.Jasno izdvajanje fenotipova na osnovu morfoloških karaktera odraslih jedinki uključujući i parametre krila (veličinu i oblik) ustanovljeno je i unutar vrsta Chrysotoxum vernale i Melanostoma mellinum. Unutar vrste Chrysotoxum vernale se izdvajaju dva nezavisna taksona- Chrysotoxum vernale i Chrysotoxum aff. vernale, a unutar vrste Melanostoma mellinum- Melanostoma mellinum i Melanostoma aff. mellinum.Zoogeografskom analizom je ustanovljeno da su najbrojnije vrste širokog areala, koje čine čak 75,19% od ukupnog broja vrsta, 12 vrsta (9,02%) ima srednjeevropski, 10 severnoevropski (7,52%), a svega dve vrste (1,5%) južnoevropski tip areala. Dve vrste (1,5%) su ograničenog areala.Dve vrste iz podfamilije Syrphinae spadaju u kategoriju strogo zaštićenih vrsta, dok pet spada u kategoriju zaštićenih vrsta na području Srbije (Uredbom Ministarstva za zaštitu životne sredine i prostornog planiranja Republike Srbije od 2010. godine o zaštiti strogo ugroženih i ugroženih divljih vrsta biljaka, životinja i gljiva). Razmatrajući status vrsta na evropskom nivou po Speight (2010) većina vrsta (118) pripada kategoriji neugroženih vrsta „unthreatened“, a po četiri kategoriji ugroženih vrsta „threatened“ i vrsta čija se brojnost smanjuje „decreasing“.Najvećim indeksom diverziteta (3,66) se odlikuje Dubašnica sa Malinikom, zatim slede Vršačke planine (H=3,62) i Kopaonik (H=3,59). Najniži indeks diverziteta imaju Bosilegrad (1,21) i dolina Tamiša (1,55) što je i očekivano obzirom na broj sakupljenih primeraka i registrovanih vrsta.Rad predstavlja sintezu faunističkih istraživanja vrsta iz podfamilije Syrphinae u Srbiji, taksonomsku analizu zabeleženih vrsta kao i razrešavanje taksonomskih problema unutar mnogih vrsta unutar kojih su oni bili prisutni.This PhD thesis is about the taxonomic and faunistic revision of the Syrphinae hoverflies (Syrphidae) of Serbia. As a result of this study, 134 species of 25 genera were reported to Serbia. This account comprised seven species new to science: Chrysotoxum orthostylus Vujić, in prep.Chryotoxum aff. festivum, Chrysotoxum aff. vernale, Dasysyrphus laskai Doczkal & Ståhls, in prep., Melanostoma aff. mellinum, Paragus rarus Vujić et al., in prep. and Xanthogramma citrofasciatum B Doczkal, in prep.. Additionally, 39 species were new to Serbia, 14 of them also new to the Balkan Peninsula.A first approach to solve some taxonomic problems within three different hoverfly taxa is provided in this study. The examined material of Chrysotoxum festivum from Serbia exhibited two different phenotypes, “light” and “dark”. These phenotypes were defined by both landmark-based geometric morphometric characters of wings and other adult morphological characters (width of face, width of black stripe on face, frons pruinosity,colour of hairs on mesonotum and scutellum, width of stripes on terga 2 and 3, etc). The presented results together with the sympatry of the studied phenotypes suggested the existence of at least two different taxa within the species, currently known under the name Chrysotoxum festivum. Similarly, traditional characters in adult morphology and morphometric characters of wings (size and shape) showed the existence of two welldefined phenotypes both within the species Chrysotoxum vernale (Chrysotoxum vernale and Chrysotoxum aff. vernale) and the species Melanostoma mellinum (Melanostoma mellinum and Melanostoma aff. mellinum).The zoogeographic analysis showed that most of the studied species are widespread in Europe (75,19%), and the rest of species are Central European (9,02%), Northern European (7,52%) or South European (1,5%).At European level, 118 species are thought to be unthreatened, four threatened and four with decreasing populations according to the last version of Syrph the Net, the Database of European Syrphidae. In Serbia, two of the studied species are regarded as “strictly protected“ and five as “protected“ under the Regulation on the Promulgation and Protection of the Protected and Strictly Protected Wild Species of Plants, Animals and Fungi (Ministry of Environment and Spatial Planning, Serbia).The localities of Dubašnica and Malinik have the highest values for the scored diversity index (H = 3.66), followed by Vršačke planine (H=3.62) and Kopaonik (H=3.59). Bosilegrad and Tamiš have the lowest diversity values, 1.21 and 1.55 respectively, as it was expected by the low species richness and abundance of hoverflies recorded in these localities.

Full textAbstract:
Osolike muve predstavljaju veoma bitnu i korisnu insekatsku grupu. Pružaju nezamenljive ekološke i ekonomske usluge, kao i usluge za životnu sredinu. Navedene usluge su omogućene njihovom sposobnošću oprašivanja biljaka u prirodnim i agroekosistemima, kao i zahvaljujući larvama– predatorima lisnih vaši i drugih insekata, smanjujući ekonomske gubitke u prinosu kultivisanih biljaka. Takođe mogu poslužiti kao bioindikatori klimatskih promena i stanja staništa. Neke vrste imaju i konzervacioni značaj, obzirom da su zbog antropogenih uticaja postale ugrožene, što zahteva preduzimanje mera za obezbeđivanje njihovog opstanka. Izuzetno bogatstvo flore i faune na Balkanskompoluostrvu predstavlja jedinstveni ekološki i biogeografski fenomen u Evropi. Grčka, kao jedna od najvažnijih centara biodiverzita na Balkanu i u Mediteranu se odlikuje širokim spektrom važnih tipova ekosistema, od kojih su najbitniji šumski, budući da najveći broj osolikih muva preferira upravo taj tip staništa.Značaj faunističkih istraživanja se ogleda u otkrivanju sastava i brojnosti vrsta na određenim staništima ili područjima. Faunistički sastav pruža uvid u biodiverzitet istraživane oblasti, koja se neprekidno menja, naročito u poslednje vreme pod uticajem negativnog antropogenog uticaja. Podaci o vrstama mogu biti od velikog značaja za eventualne programe zaštite i oporavka ugroženih vrsta, kao i u planiranju formiranja novih zaštićenih područja ili u uvođenju novih mera zaštite u već postojećim prirodnim dobrima.Prepoznavanje ugroženih vrsta ili ugroženih staništa koje one naseljavaju, igra bitnu ulogu u planiranju konzervacionih strategija za njihovo očuvanje. Rezultati doktorske disertacije upotpunjujuznanje o faunističkom sastavu, taksonomiji, distribuciji i diverzitetu osolikih muva u Grčkoj. Pomoću sakupljenih podataka formiran je identifikacioni ključ za razlikovanje kako rodova tako i vrsta registrovanih na ovom području, što u velikoj meri pomaže u daljim faunističkim istraživanjima. Kao rezultat ove doktorske disertacije dobijena je konačna lista od 418 vrsta iz 83 roda. Od ukupnog broja zabeleženih vrsta 64 vrste su prvi put registrovane na teritoriji Grčke, dok su 18 vrsta nove za nauku.Osnovni cilj ovog rada je revizija faune osolikih muva Grčke na osnovu prikupljenog materijala iz publikovanih i nepublikovanih zbirki i dopunskihterenskih istraživanja, sastavljanje liste o svim poznatim vrstama sa područja Grčke, i izrada identifikacionog ključa za razlikovanje zabeleženih rodova i vrsta(praćeni fotografijama i crtežima dijagnostičkih morfoloških karaktera adultnih jedinki). Drugi deo doktorske disertacije se bavi prepoznavanjem retkih iugroženih vrsta Grčke sa naglaskom na njihovu zaštitu i konzervaciju. U okviru disertacije je izvršena prostorna analiza distribucije vrsta na području Grčke, koja su već ugrožena na evropskom i balkanskom nivou, a u cilju određivanja područja sa posebnim značajem za njihovo očuvanje.Hoverflies are a very important and useful insect group. They provide irreplaceable environmental and economic services, as well as environmental services. These services are enabled by their ability to pollinate plants in natural and agroecosystems, as well as thanks to larvaepredators of aphids and other insects, reducing economic losses in the yield of cultivated plants. Hoverflies are extremely important for the environment, as they can serve as bioindicators of climate change and habitat conditions. Some species also have conservation importance, since they have become endangered due to anthropogenic effects, which requires taking measures to ensure their survival. The extraordinary richness of flora and fauna on the Balkan Peninsula represents a unique ecological and biogeographical phenomenon in Europe. Greece, as one of the most important center of biodiversity in the Balkans and in the Mediterranean, is characterized by a wide spectrum of important ecosystem types, the most important of which are forests, since the largest number of hoverflies prefer this type of habitat.The importance of faunal research is reflected in the discovery of the composition and number of species in specific habitats or areas. The faunal composition provides an insight into the biodiversity of the investigated area, which is constantly changing, especially lately under the influence of negative anthropogenic impact. Data about species can be of great importance for possible programs for the protection and recovery of endangered species, as well as in the planning of the formation of new protected areas or in the introduction of new measures of protection in already existing natural resources. Identifying endangered species or endangered habitats they inhabit plays an important role in planning conservation strategies for their conservation.The results of these thesis complement the knowledge of the fauna composition, taxonomy, distribution and diversity of hoverflies in Greece. Using the collected data, an identification key was formed to distinguish both the genera and species registered in this area, which greatly assisted in further faunistic research. As a result of these thesis a final list of 418 species rom 83 genus was obtained. Of the total number of recorded species, 64 species were first time registered in the territory of Greece, while a total of 18 species are new to science. The main goal of this paper is to revise the fauna of Greek howerflies based on the collected material from published and unpublished collections and additional field research, compile a list of all known species from Greece, and create an identification key to distinguish the recorded genera and species (accompanied by photographs and drawings of diagnostic morphological characters of adult individuals). The second part of the thesis deals with the identification of rare and endangered species of Greece with an emphasis on their protection and conservation. Within the framework of the dissertation, a spatial analysis of the distribution of species in Greece was carried out, already threatened at the European and Balkan levels, in order to determine areas of specialsignificance for their preservation.

Analizom PGM zimograma, u okviru prethodnodefinisane "prolećne generacije" determinisana je populacija sa Kopaonika taksona M. aeneus B aeneuskompleksa. Determinacija kriptičnih taksona M. cinereus A i M. cinereus B izvršena je na osnovu speciesspecifičnihgenotipova Had lokusa. Najveći broj dijagnostičkih lokusa registrovan je između vrsta M.desuturinus i M. funestus, kao i između navedenih vrsta i ostalih vrsta aeneus kompleksa. Utvrđen je idijagnostički značaj većine analiziranih lokusa: Aat, Fum, Gpd-2, Hk-2, Hk-3, Idh-2, Mdh-2, Me, Pgm iSod-1. Na osnovu genetičkih markera Aat i Idh-2 lokusa i dijagnostičkih morfoloških karakteraidentifikovane su sestrinske vrste M. avidus A i M. avidus B.Stepen genetičke diferencijacije između vrsta u okviru ruficornis i aeneus grupa bio je veći uodnosu na blisko srodne vrste aeneus i cinereus kompleksa i sestrinskih vrsta avidus grupe. Na genetičkuidentičnost ukazuje 52,94% (ruficornis grupa) i 55,56% (aeneus grupa) vrednosti genetičke bliskosti polokusu, odnosno, potpuna genetička različitost registrovana je u 25,41% (ruficornis grupa) i 25,49%(aeneus grupa) analiza.Na osnovu prosečne genetičke bliskosti i klaster analize u okviru ruficornis grupe diferencirana jegrupa blisko srodnih vrsta M. armipes, M. ruficornis i M. recurvus u odnosu na genetički udaljene vrste,M. crymensis i M. loewi. Dendrogramom genetičkih odnosa između vrsta aeneus grupe formirana jemonofiletska grupa vrsta aeneus i cinereus kompleksa, nasuprot genetički udaljenim vrstama M. funestus iM. desuturinus.Utvrđena je veća zastupljenost vrednosti genetičke bliskosti po lokusu, mere genetičkeidentičnosti (37,44%) i manji procenat pokazatelja genetičke različitosti (47,80%) između vrsta aeneus iavidus grupa u odnosu na vrste ruficornis i avidus grupe (29,84% i 58,09%). Na visok stepen genetičkihrazlika između kongeneričkih vrsta roda Merodon ukazuje najveća procentualna zastupljenost vrednostigenetičke bliskosti po lokusu, pokazatelja genetičke različitosti (62,01%) i mali stepen genetičkeidentičnosti (26,84%).Utvrđen je pleziomorfan karakter Gpi (Gpijl), Hk-2, Hk-3 (Hkc) i Mdh-2 (Mdh-2e) lokusa vrstaruficornis, aeneus i avidus grupa roda Merodon, kao i predački aleli Gpii, Gpij, i Pgmf vrsta avidus iaeneus grupa. Poređenjem alozima determinisanih alelima 10 lokusa populacija vrste Cheilosia vernalis,suprageneričke out vrste, i populacija vrsta roda Merodon, registrovani su identični aleli samo u Fum iPgm lokusima.Gene-enzyme variability of the ruficornis (11 populations: M. ruficornis, M. armipes, M.crymensis, M. loewi and M. recurvus), aeneus (11 populations: M. aeneus: M. aeneus A, M. aeneus B, M.aeneus C, M. cinereus A, M. cinereus B, M. funestus and M. desuturinus) and avidus (7 populations: M.avidus A and M. avidus B) groups of species of the genus Merodon and four Cheilosia vernalispopulations from the Balkan peninsula was analyzed using PAGE (polyacrilamide electrophoresis).Allozyme variability of 17 loci in the ruficornis species group (Aat, Fum, Gpd-1, Gpd-2, Gpi, Had, Hk-2,Hk-3, Idh-1, Idh-2, Mdh-1, Mdh-2, Me, Pgm, Sod-1, Sod-2, Sod-3), 17 loci in the aeneus species group(Aat, Fum, Gpd-2, Gpi, Had, Hk-2, Hk-3, Idh-2, Mdh-1, Mdh-2, Me, Pgm, Sod-1, Sod-2, Sod-3), 16 loci inthe avidus species group (Aat, Ao, Fum, Gpd-2, Gpi, Had, Hk-2, Hk-3, Idh-2, Mdh-1, Mdh-2, Me, Pgm,Sod-1, Sod-2, Sod-3) and 12 loci in Ch. vernalis populations (Fum, Gpd-2, Gpi, Had, Hk-2, Hk-3, Idh-1,Idh-2, Mdh-1, Mdh-2, Pgm, Sod-1) was evaluated.Diagnostic value of Aat, Fum, Had, Hk-2, Hk-3, Mdh-2, Me, Pgm and Sod-1 loci was determinedby the population-genetic analysis of the ruficornis species group. The species were identified usingspecies-specific alleles and genetic-biochemical key was formed. Allozyme variability analysis of theaeneus species group populations enabled discrimination of the cryptic taxa: M. aeneus A, M. aeneus B,M. aeneus C, M. cinereus A and M. cinereus B. In sympatric and alochronic populations of the species M.aeneus A and M. aeneus diagnostic loci were observed (Had, Sod-1, Me, Aat and Pgm). Analysis of thePGM zymogram allowed the identification of the cryptic species M. aeneus B in the previously delineated"spring generation" from Kopaonik. Cryptic taxa M. cinereus A and M. cinereus B were discriminatedbased on the species-specific genotypes at the Had locus. The largest numbers of the diagnostic loci wereregistered for differentiating M. desuturinus and M. funestus species, and between these two and otherspecies of the aeneus complex. Diagnostic value was recorded for the analyzed loci: Aat, Fum, Gpd-2, Hk-2, Hk-3, Idh-2, Mdh-2, Me, Pgm and Sod-1. Sibling species M. avidus A and M. avidus B were identifiedusing genetic markers of Aat and Idh-2 loci and diagnostic morphological characters.The degree of genetic differentiation between the species of the ruficornis and the aeneus groupswas higher comparing to closely related species of the aeneus and the cinereus complexes and siblingspecies of the avidus group. Out of the performed analyses, 52.94% (ruficornis group) and 55.56%(aeneus group) of the genetic identity values for loci point to genetic identity, while complete geneticdifference was registered in 25.41% (ruficornis group) and 25.49% (aeneus group).Average values of the genetic identity and cluster analysis enabled differentiating the groups ofclosely related (M. armipes, M. ruficornis and M. recurvus) and genetically distant species (M. crymensisand M. loewi) in the ruficornis group. Based on dendrogram of genetic relationships between the speciesof the aeneus group, monophyletic group of the aeneus and the cinereus complex species was formed, asopposed to genetically distant species M. funestus and M. desuturinus.Genetic identity among loci between the aeneus and the avidus groups was higher (37.44%) whilegenetic distance was lower (47.80%) in comparison to the corresponding values for the ruficornis and theavidus groups of species (29.84% and 58.09%). High values of genetic difference (62.01%) and lowvalues of genetic identity (26.84%) indicate great genetic difference between congeneric species of thegenus Merodon.Pleziomorphous character of Gpi (Gpijl), Hk-2, Hk-3 (Hkc) and Mdh-2 (Mdh-2e) loci in theruficornis, aeneus and avidus species groups of the genus Merodon and ancestral alleles (Gpii, Gpij, Pgmf) in the avidus and the aeneus species groups were registered.Comparison of allozymes of the suprageneric out species Ch. vernalis and the populations of thegenus Merodon revealed identical alleles only in Fum and Pgm loci.

Род Merodon Meigen (Diptera: Syrphidae) се одликује великм бројем врста које имају функцију у опрашивању биљака. У оквиру овог рода својом разноврсношћу издваја се Merodon aureus група врста коју поред фенотипски различитих одликује и присуство већег броја криптичних врста. Због морфолошке сличности криптичне врсте представљају изазов за таксономе, те су молекуларне методе од посебног значаја. У том светлу примарни циљ овог истраживања је био утврђивање молекуларног диверзитета групе и могућности његове примене у таксономији. Истраживање је било засновано на анализи варијабилности секвенци COI и 28S рРНК гена за 718 јединки 41 описане или новоткривене врсте сирфида. Додатно, тестирана је примењивост мултилокусних ISSR маркера у раздвајању врста M. luteomaculatus комплекса. Узорци су тестирани и на присуство Wolbachia с обзиром да она може утицати на еволуцију митохондријалних гена. Добијени резултати су указали на високу варијабилност секвенци COI гена који се показао корисним у утврђивању граница криптичних врста у анализираним комплексима. Секвенце 28Ѕ рРНК гена у већини случајева нису биле од већег значаја за раздвајање врста, али би могле имати потенцијал у раздвајању комплекса или подгрупа врста као допуна анализи секвенци COI гена. Додатно, ISSR маркери су показали потенцијал за примену у молекуларној таксономији. Све анализиране врсте изузев М. balkanicus су биле заражене Wolbachia, али није утврђена јасна веза између варијабилности секвенци митохондријалног COI гена и инфекционог статуса врста. Утврђен образац генетичке варијабилности је вероватно обликован драстичним климатским променама током Плеистоцена и фрагментацијом хабитата.

Genus Merodon Meigen (Diptera: Syrphidae) is characterized by a large number of species which have a function in plants pollination. Within this genus, Merodon aureus species group is distinguished by its diversity and it is characterized not only by phenotypically divergent species but also with a large number of cryptic species. Because of the high morphological similarity, cryptic species are a challenge for taxonomist, thus molecular methods are of special importance. The primary goal of this research was to determine the molecular diversity of the group and the possibility of its application in taxonomy. The study was based on the sequences variability analysis of COI and 28S rRNA genes for 718 individuals belonging to 41 described or newly discovered hoverfly species. Additionally, the applicability in species delimitation of multilocus marker ISSR was tested on M. luteomaculatus species complex. Specimens have also been tested for Wolbachia since it may affect the evolution of mitochondrial genes. The obtained results indicated a high variability of the COI gene sequences that proved useful for determining the cryptic species boundaries in the analyzed complexes. Sequences of the 28S rRNA gene in most cases were not of much significance for the species delimitation, but they could have the potential to separate species complexes оr subgroups as a complement to the analysis of the COI gene sequences. Additionally, the ISSR markers showed potential for application in molecular taxonomy. All analyzed species except M. balkanicus were infected with Wolbachia, but no clear relation was established between the sequence variability of the mitochondrial COI gene and the infectious status of species. The established pattern of genetic variability is probably shaped by drastic climatic changes during Pleistocene and habitats fragmentation. In order to achieve the final conclusions on the taxonomic status of the proposed species, it is necessary to integrate the obtained results with the data of other relevant scientific disciplines.

Larvas de Syrphidae (Diptera) predadoras se destacam como agentes de controle, principalmente de pulgões, entretanto o estudo de sua comunidade no ambiente agrícola é escasso no Brasil. Desse modo, este trabalho teve como objetivo analisar a entomofauna de Syrphidae em sistemas agrícolas de citros (laranjeira) (MP); soja com sucessão de trigo e milho (MA), hortaliças (HO) e fragmento de mata (MT) e observar a variação populacional das espécies dominantes, em Londrina-PR. O experimento ocorreu entre novembro/2013 e novembro/2014, com instalação de armadilhas Malaise. As coletas foram semanais, e os insetos levados ao laboratório para identificação através de chaves específicas. Mensalmente, plantas espontâneas foram amostradas, aleatoriamente, com quatro moldes de um m2 por área, sendo identificadas e calculada a porcentagem de cobertura do solo (CP). Foram registrados dados de temperatura (T: med, min e max), velocidade do vento (V: med e max), precipitação pluviométrica (P), radiação solar (RS) e umidade relativa (UR). Abundância de Syrphidae e dados climáticos foram ultizados para verificação de correlação (Pearson). Foi capturado um total de 10.026 sirfídeos, perfazendo 80,0% em HO, 15,8% em MP e 4,2% em MA. Foram identificadas 29 espécies e 11 morfoespécies de Syrphidae, sendo HO a mais diversa (S=32) e MA a menos rica (S=16). Quanto às plantas daninhas, foram identificadas 34 espécies, sendo a área HO com maior riqueza e CP média (S=28; 55,1), seguida de MP (S=22; 25,3) e MA (S=9; 4,4). Toxomerus foi o gênero mais abundante e de maior riqueza em HO e MP. Allograpta foi o de maior abundância em MA. Os dados de correlação demonstraram que a variação da abundância de A. exotica correlacionou inversamente à de Tmed, RS e Vmed em HO. T. virgulatus, em MP, teve correlação inversa com RS, Vmed e Tmed. Assim como T. politus em trigo. Pseudodoros clavatus teve correlação positiva para RS e Tmed em HO. T. dispar e T. watsoni são influenciados pelos mesmos fatores ambientais em HO, correlacionando positivamente com RS, Vmed, Tmax e CP; e negativamente com P e UR. A precipitação teve influência negativa à neutra na abundância de Syrphidae em todos tratamentos. Esse estudo confirmou que a abundância e diversidade de recursos florais impactam na quantidade de Syrphidae quando comparamos HO, com as demais áreas. Raphanus raphanistrum pode ser importante na atração de sirfídeos. P. clavatus, T. dispar e T. watsoni correlacionam-se com temperaturas altas, UR baixa e baixa precipitação; esses predadores podem ser destacados como objetos de estudo quanto a eficiência de predação em campo e seu uso estratégico no manejo de pragas.Predatory Syrphidae (Diptera) larvae stand out as control agents, especially of aphids, however the study of their community in the agricultural environment is scarce in Brazil. Thus, this study aimed to analyze the entomofauna of Syrphidae in agricultural systems of citrus (orange) (MP); soybean in succession of wheat and maize (MA), vegetables (HO) and forest fragment (MT), and observe the population varietion of the dominant species, in Londrina. The experiment took place between November/2013 and November/2014 with installation of Malaise traps. The samples were weekly, and insects taken to the laboratory for identification through specific keys. Weeds were randomly sampled monthly, with four molds of one m2 per area; they were identified and calculated the percentage of ground cover (CP). Temperature data were recorded (T: med, min and max), wind speed (V: med and max), rainfall (P), solar radiation (RS) and relative humidity (UR). Overall Syrphidae and environmental data were used to correction (Pearson) verification. A total of 10,026 syrphids was captured, totaling 80.0% of HO, 15.8% MP and 4.2% in MA. Twenty-nine species and eleven morphospecies of Syrphidae were identified, HO was the most diverse (S = 32) and MA the less rich (S = 16). As for weeds, 34 species were identified, the HO area with the highest diversity and average CP (S = 28; 55.1), followed by MP (S = 22; 25.3) and MA (S = 9; 4.4). Toxomerus was the most abundant and richer genus in HO and MP. Allograpta was the most abundant in MA. The correlation analisys has shown that A. exotica abundance variation was inversely correlated to Tmed, RS and Vmed in HO. T. virgulatus fluctuation in MP, had an inverse correlation with RS, Vmed and Tmed. As T. politus in wheat. Pseudodoros clavatus had positive correlation to RS and Tmed in HO. T. dispar and T. watsoni were influenced by the same environmental factors in HO, correlating positively with RS, Vmed, Tmax and CP; and negatively with P and UR. Rainfall had negative influence to neutral in the abundance of Syrphidae in all treatments. This study confirmed that the abundance and diversity of floral resources impact the amount of Syrphidae when comparing HO, with the other areas. Raphanus raphanistrum may be important in attracting syrphids. P. clavatus, T. dispar and T. watsoni correlate with high temperatures, low UR and low rainfall; these predators can be indicated as objects of study regarding their field predation efficiency and strategic use in pest management.

Full textAbstract:
U radu je izvršen integrativno-taksonomski pristup analize kompleksa vrsta Merodon avidus (Diptera: Syrphidae), na geografski i vemenski obimnom materijalu. U okviru genetičke karakterizacije kriptičnih vrsta navedenog kompleksa, bazirane na 3' i 5'fragmentima mitohondrijalnog COI gena, određeni su parametri genetičke varijabilnosti i utvrđeni jedinstveni i deljeni haplotipovi u okviru i između pretpostavljenih vrsta. Rezultati genetičke varijabilnosti COI DNK sekvenci pokazali su da jedinke sa ostrva Krf i Evia i poluostrva Peloponez, preliminarno identifikovane kao M. moenium, predstavljaju novu, endemsku vrstu proučavanogkompleksa. Dijagnostički enzimski lokusi pokazali su da M. avidus i M. moenium predstavljaju sestrinske vrste, koje su se, u okviru kompleksa vrsta M. avidus, poslednje razdvojile. Zaključeno je da se kompleks vrsta M. avidus sastoji od 5 vrsta: M. avidus, M. moenium, M. megavidus, M. ibericus i M. aff. moenium. U nastavku, oslanjajući se na moderne tehnike veštačke inteligencije, izvršeno je modelovanje distribucije vrsta i poređenje sličnosti utvrđenih ekoloških niša. U poslednjem segmentu istraživanja, prednosti veštačke inteligencije iskorišćene su u modelovanju sistema za determinaciju jedinki sestrinskih vrsta u uzorku, na osnovu adekvatne varijable.Ovo istraživanje doprinelo je karakterizaciji biodiverziteta osolikih muva, rasvetljavanju taksonomskog statusa vrsta i kreiranju smernica za definisanje budućih konzervacionih programa zaštite biodiverziteta vrsta Merodon avidus kompleksa.During this research, an integrative-taxonomic analysis of M. avidus species complex was performed. The study was based on geographically and temporally extensive material. Genetic characterisation of cryptic species, based on 5’ and 3’ regions of COI gene, defined parameters of genetic variability. Shared and unique haplotypes between and within of cryptic species were detected. The results of genetic variability analysis based on COI gene showed that specimens from the islands Corfu, Evia and half-island Peloponnese, which were preliminarily identified as M. moenium, represent a new, endemic species of the selected complex. Diagnostic enzyme loci showed that M. avidus and M. moenium represent sibling species, which were the last one who separated within M. avidus complex. According to current information, it was concluded that M. avidus complex consists of 5 species: M. avidus, M. moenium, M. megavidus, M. ibericus and M. aff. moenium. In the next chapter, relying on modern techniques of artificial intelligence, the species distribution modelling and the comparison of ecological niches were performed. In the last part of the research, the advantages of artificial intelligence were used in order to model a system that was able to determinate one of two sibling species, based on appropriate predictor. This research has generally contributed to a characterization of hoverfly diversity and helped resolving a taxonomic status of species in one of the most challenging groups in Syrphidae family. Genetic differentiation data represent directions for defining future conservation strategies for biodiversity protection of defined cryptic species of Merodon avidus complex

Dobijeni podaci su korišćeni u sagledavanju filogenetskih i evolucionih odnosa odabranih taksona. Amplificiran je i sekvenciran 3' kraj gena COI mtDNK 119 jedinki 14 vrsta roda Cheilosiasakupljenih na 8 lokaliteta Balkanskog poluostrva i u Laponiji, Finska (vrsta C. albitarsis). Analizom su bile obuhvaćene i sekvence COI mtDNK devet vrsta C. melanuragrupe i tri vrste C. canicularis grupe preuzete iz Banke Gena. Geometrijsko morfometrijskom metodom analizirane su veličinske komponente desnog krila (oblik i veličina) 4717 jedinki 29 vrsta roda Cheilosia poreklom sa 21 područja Balkanskog poluostrva.U radu su utvrđeni diferencijalni fenotipovi veličine i oblika krila i specijes-specifični haplotipovi COI mtDNK koji su omogućili identifikaciju i razdvajanje blisko srodnih vrsta roda Cheilosia. Analizom parametara krila kod većine analiziranih taksona utvrđene su značajne razlike između konspecifičkih populacija većine analiziranih taksona, kod je jasan polni dimorfizam u obliku krila uočen kod svih analiziranih vrsta.Usaglašeno filogenetsko stablo na osnovu sekvenci 3' COI mtDNK ukazuje na monofiletski rod Cheilosiau okviru kojeg se izdvajaju četiri jasno odvojene klade koje odgovaraju podrodovima Convocheila, Taeniochilosia, Eucartosyrphusi Cheilosias. str. definisanim na osnovu morfoloških karaktera tradicionalnom taksonomijom (((Cheilosia s. str. + Eucartosyrphus) + Taeniochilosia) + Convocheila).

Obtained data were used to solve phylogenetic and evolutionary relationships of these taxa. A total of 119 specimens from 14 Cheilosiaspecies collected from eight localities on the Balkan Peninsula and one from Finnish Lapland (specimens of C. albitarsis) were used for DNA sequencing. Amplification was attempted for 3' end of COI mtDNA gene (and 5' COI mtDNA and ITS2 rDNA in C. laticornis species group). COI mtDNA sequences from nine species of the C. melanura group and three species of the C. canicularis group were obtained from GenBank. Geometric morphometric analysis of wing size and shape was conducted on 4717 specimens from 29 species collected from 21 localities on the Balkan Peninsula.Based on differential phenotypes of wing size and shape and species-specific COI mtDNA haplotypes it was possible to identify and delimitate closely related species of genus Cheilosia. It was estimated that size and shape variation occurred among conspecific populations. A consistent sexual wing shape dimorphism was revealed in all analyzed species.Strict consensus cladogram based on COI mtDNA data revealed monophyletic genus Cheilosia and subgeneric divisions that are congruent with subgenera described based on traditional morphological character (((Cheilosia s. str. + Eucartosyrphus) + Taeniochilosia) + Convocheila). Within the clade Cheilosias. str. closely related species group were supported as monophyletic. UPGMA phenograms of evolutionary relationships based od wing traits produced the same topology as the phylogenetictrees constructed using molecular data.

Mención Sanidad vegetalPara describir los estadíos juveniles de los representantes más abundantes del género Allograpta en la Región Metropolitana, se hicieron capturas periódicas con red entomológica en sectores sin tratamientos de insecticidas en la comuna de La Pintana. Los individuos capturados se identificaron y sexaron, con el fin de poner a las hembras fertilizadas en contenedores que tuvieran las condiciones ideales para la ovoposición. Se logró criar y completar el ciclo de tres especies: A. hortensis (Philippi), A. exotica (Wiedemann) y A. pulchra Shannon, y se hicieron las respectivas descripciones morfológicas de los estados de huevo; larvas I, II y III, y pupa. Estas descripciones se utilizaron para elaborar una clave de estadíos juveniles del género Allograpta que permite identificar de manera simple y certera a las tres especies indicadas. Paralelamente, se hicieron observaciones de otros géneros de sírfidos afidófagos presentes en el lugar de estudio, lo que permitió determinar características propias del género en estudio. El conocimiento de los sírfidos afidófagos en sus distintos estados de desarrollo permitirá efectuar nuevos estudios con miras al control biológico y manejo integrado de plagas.
To describe the juvenile stadia of the most abundant representatives of the genus Allograpta in the Metropolitan Region of Chile, periodic samples were obtained with an entomological net from blooming plants in areas unexposed to insecticides in La Pintana commune, Santiago, Chile. The specimens were identified and sexed to set the fertilized females in conditions ideal for oviposition. Three species were reared to the completion of their cycle: A. hortensis (Philippi), A. exotica (Wiedemann) y A. pulchra Shannon, and the corrresponding morphological descriptions of their eggs, larvae I, II, and III, and pupae were made. These descriptions were used to build a key for the identification of juvenile stages of the genus Allograpta that allows for a simple and clear identification of the three species indicated. Also, observations of other aphid-feeding syrphid fly genera present in the study area allowed to determine morphological characteristics present in the genus studied. The knowledge of the aphid-feeding syrphids in their different development stages will allow for further studies focused on their potential use in biological control and integrated pest management of aphids.

Full textAbstract:
Abstract Big-headed flies are endoparasites of various families of Homoptera, especially Cicadellidae and Delphacidae, and are important as biological control agents, The adults are frequently seen hovering in and over vegetation; their flight is similar to that of Syrphidae. The female search for nymphs of leafhoppers and other Homoptera, as hosts in which to deposit their eggs. They snatch their prey with their legs and hold them using their strong tarsal claws. While in flight, they insert the egg into the host through the conjunctiva between the abdominal segments. The larvae develop to maturity within the hosts and at full size fill the entire body cavity. After escaping from the host, the larvae drop to the ground and pupate in the soil, in the ground litter, at the base of plants, or in crotches of trees.

Rykken, Jessica. Pollinator diversity and floral associations in subarctic sand dunes of Kobuk Valley National Park, Alaska. National Park Service, 2024. http://dx.doi.org/10.36967/2302008.
Full textAbstract:
Active sand dunes in Kobuk Valley National Park are a regionally rare and ecologically distinct landscape feature occurring within the northern boreal biome. The sand dunes harbor a rich diversity of plants, including several rare and disjunct species and the endemic Kobuk locoweed (Oxytropis kobukensis). Pollinators associated with these dune plants have not been studied in Kobuk Valley, despite their essential role in transporting pollen which many plants rely on for successful reproduction. In order to gain a better understanding of pollinator diversity and plant-pollinator associations in this unique ecosystem north of the Arctic Circle, we conducted surveys of bees (Hymenoptera: Anthophila) and syrphid flies (Diptera: Syrphidae) in several places along the Kobuk River and in two active dune areas, the Hunt River Dunes and the Great Kobuk Sand Dunes, in late June-early July of 2017 and 2019. We used active and passive collecting methods to sample pollinators at 21 different sites and along five walking transects, and we documented plant associations for net-collected specimens. In all, we collected 326 bees and 256 syrphid flies, representing 27 and 37 taxa, respectively. The most abundant and widespread species collected among syrphid flies were Lapposyrpus lapponicus and Eristalis obscura. For bees, three soil-nesting solitary species, Andrena barbilabris, Megachile circumcincta, and Osmia tarsata made up 60% of the total bee catch. Dryas integrifolia, a widespread plant on the dunes, hosted the highest number of bee and syrphid fly taxa (13 and 20, respectively). Bumble bees (Bombus) and megachilid bees (Megachile, Osmia) favored several plants in the Fabaceae family, while mining bees (Andrena) were abundant on Salix species (willow). A high diversity of syrphid flies were collected on the composite Packera ogotorukensis, and Salix species. Our collections indicate that the endemic Oxytropis kobukensis was primarily visited by the mason bee, Osmia tarsata (44% of all visitors) and the leafcutter bee, Megachile circumcincta (27%). Bumble bees (genus Bombus) made up another 13% of all visitors to this plant. Our study confirms that the active sand dunes in Kobuk Valley provide an ecologically unique habitat both for plants and their associated insect pollinators. For example, many of the solitary bees living in the dunes rely on deep sands for nesting and thus are limited in their distribution across Arctic and boreal landscapes.
