Abstract:

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.

Abstract:

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.

Abstract:

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.

Abstract:

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.

Abstract:

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.

Abstract:

The influence of different semi-natural surroundings adjacent to apple orchards on the occurrence of predatory syrphids and biological control of Aphis pomi Deg. and Dysaphis plantaginea Pass. was compared. Two methods of catching hoverflies were used: yellow traps to collect the adults and hand picking to get the larvae from aphid colonies. A total of 1029 Syrphidae (26 species belonging to 14 genera) of subfamily Syrphinae were collected in Moericke traps from apple orchards and their boundaries. At all sites, a much greater number of hoverflies was collected in the surroundings (638 specimens) than in the orchards (391 specimens). In apple orchards, 134 syrphids belonging to 10 species were reared from A. pomi and D. plantaginea colonies. In both cases, the dominants were Episyrphus balteatus (Deg.) Eupeodes corollae (Fabr.), Syrphus vitripennis Meig. and S. scripta (L.), suggesting that hoverflies are attracted by plants flowering in semi-natural habitats in the vicinity of the orchard, and they then migrate to the orchard and reduce the aphid colonies. The results confirmed the positive influence of natural surroundings on the conservation of aphid predators.

Abstract:

Agroecosystems produce profound alterations on the structure and functioning of the original environment, mainly due to the reduction of biodiversity. Flower flies (Diptera: Syrphidae) are potentially useful organisms for the diverse ecosystem services they provide. We studied syrphids collected in a Pampean agroecosystem to assess richness, abundance, host plants, and the ecosystem services they could offer. Flower flies were represented by three subfamilies, eight tribes, 17 genera, and 26 species/morphospecies. Adults of these flies visited flowers of 44 species of wild and/or cultivated plants and exhibited a generalist interaction pattern. Larvae of the most abundant species were predators (mainly soft-bodied Hemiptera) and/or decomposers/aquatic filters. Only one species was pollinivorous. Our results, together with the scarce published bibliography, suggest that the syrphid communities of the highly modified Pampean region are composed of a few very abundant species and many rare or low representative species.

Abstract:

Bees, hoverflies and butterflies are taxa frequently studied as pollinators in agricultural and conservation contexts. Although there are many records of non-syrphid Diptera visiting flowers, they are generally not regarded as important pollinators. We use data from 30 pollen-transport networks and 71 pollinator-visitation networks to compare the importance of various flower-visiting taxa as pollen-vectors. We specifically compare non-syrphid Diptera and Syrphidae to determine whether neglect of the former in the literature is justified. We found no significant difference in pollen-loads between the syrphid and non-syrphid Diptera. Moreover, there was no significant difference in the level of specialization between the two groups in the pollen-transport networks, though the Syrphidae had significantly greater visitation evenness. Flower visitation data from 33 farms showed that non-syrphid Diptera made up the majority of the flower-visiting Diptera in the agricultural studies (on average 82% abundance and 73% species richness), and we estimate that non-syrphid Diptera carry 84% of total pollen carried by farmland Diptera. As important pollinators, such as bees, have suffered serious declines, it would be prudent to improve our understanding of the role of non-syrphid Diptera as pollinators.

Abstract:

An intriguing ecological interaction can exist between aphids and Syrphid flies, particularly in the setting of millet crops. Aphids (Order Hemiptera: Family Aphididae) are a problem variety of crops, including all types of millets. Syrphid flies (Order Diptera: Family Syrphidae) naturally prey on aphids when they are in their larval stage. Syrphid fly larvae are referred to as "aphid lions" or "hoverfly larvae." Aphids are the main source of food for these larvae, and they manage the aphid population in millet crops. Therefore, Syrphids are used as natural enemies and biological control agents and syrphid flies are advantageous insects in agriculture. The present study was conducted in the month of August 2021 to March 2022 (summer and winter season) to find out the population dynamic of syrphid flies in agricultural farms and the campus of ITM University. The target crops like maize, sorghum, pearl millets, okra, mustard crop, cabbage cauliflower, marigold and brinjal were tagged and marked and Syrphid fly larvae and pupa were counted four times in a month. The larvae and pupa were also collected and kept for adult emergence. The maximum number of larvae were collected from the Turari campus and were as a minimum found in CRC 2. The other predator like lady bird beetles were also observed but their population was very minor. The population of syrphid flies and larvae depends on the climatic conditions and the availability of foods and their prey.

Abstract:

Alaska Wild Rhubarb (Koenigia alaskana var. glabrescens; Polygonaceae) is a native Arctic, subarctic, and alpine plant of northwestern North America. Although the plant has some economic and ecological importance, its biology is poorly known. At 11 sites in the northeast corner of its range in Northwest Territories, we found that 87% of its floral visitors were flies, mostly Syrphidae, a diverse family known to be important pollinators. Insects visiting consecutive flowers on different plants and, thus, likely effecting pollination were also flies (78.6%) and also mostly Syrphidae (72.7%) followed by Hymenoptera (20%). Although syrphids were the dominant potential pollinators at most sites, there was some variation among sites. Our results provide quantitative support for pollinator diversity and the major role of Syrphidae in pollination of Alaska Wild Rhubarb. We suggest that pollination is not a limiting factor in this plant’s spread, nor its rare and local occurrence and restricted distribution, because the majority of its pollinators are widespread.

Abstract:

Um inventariamento dos sifídeos foi realizado em cinco áreas com situações florísticas diferentes dentro do Parque Estadual Vila Velha, Ponta Grossa, Paraná, sul do Brasil. As áreas foram classificadas como Borda, Araucária, estágio inicial de sucessão (Fase 1), estágio intermediário de sucessão (Fase 2) e estágio avançado de sucessão (Fase 3). As coletas foram semanais durante o período de Setembro/1999 a Agosto/2000 utilizando-se armadilha Malaise. Aproximadamente 300.000 dípteros foram capturados nas áreas (apresentadas em ordem de abundância): Araucária (n=74.331 indivíduos, 25% do total), Fase 1 (73.782; 25%), Fase 3 (59.339; 20%), Fase 2 (53.623; 18%) e borda (38.796; 13%). Um total de 1.345 indivíduos de Syrphidae, de 97 espécies, foram identificados. As maiores abundância e riqueza de espécies foram encontradas na Borda (n=684 espécimes em 54 espécies), seguida pela Fase 1 (250; 51), Araucária (162; 34), Fase 3 (146; 31) e Fase 2 (103; 27). A abundância de Syrphidae não se correlacionou à de Diptera em nenhuma área. Syrphidae foi mais abundante na Borda e Diptera na área de Araucária. Syrphinae (82% de todos os sirfídeos coletados), Microdontinae e Eristalinae foram registrados nas cinco áreas. Dos três estágios de sucessão vegetal, a subfamília Syrphinae foi mais representativa na Fase 1, ocorrendo de forma similar nas outras duas áreas. As maiores abundância e riqueza de espécies ocorreram nas áreas mais perturbadas antropicamente (Borda e Fase 1), enquanto que as menos perturbadas apresentaram menores abundância e riqueza (Fase 2 e Fase 3). A análise de agrupamento mostrou que as áreas em sucessão vegetal avançadas são mais similares e a de borda a mais diferenciada.

Abstract:

The female abdomen of Syrphidae was studied based on a sample from all currently recognized tribes, except Spheginobacchini. All characters found were compared with previous literature on Syrphidae female abdomen and some were proposed as diagnostic for the taxa. The condition of the postabdomen distinguishes Pipizinae from the Syrphinae. Presence of sclerotized areas on the intersegmental membrane appears characteristic of the Rhingiini. Tergite and sternite 6 had unique characteristics only found in Cerioidini, and sternite 8 had a condition only found in Cerioidini and Callicerini. Notiocheilosia (Callicerini) seems more similar to Nausigaster (Eumerini). Characters present in both the Eristalini and Sericomyiini are presented. The condition of the epiproct, and of its apodemes, proved diagnostic for Microdontini, Volucellini and some Syrphini plus the Paragini. Bacchini sensu lato and Toxomerini were also distinct. The Milesiini still need to be sampled more broadly to ascertain about its relationships with other tribes and within.

Abstract:

Abstract The aim of the research was to study the diversity of hoverflies (Syrphidae: Diptera) living in areas under the influence of heavy metal emissions (Cd, Zn and Pb). Although the area of the Olkusz Ore-bearing Region (OOR), where the research was partially conducted, belongs to the contaminated regions, where a relatively high species richness of Syrphids has been noted. During the research period, a total of 1,180 syrphids, belonging to 165 species were caught, which constitutes 39.76% of all the Polish Syrphidae fauna. These species represented all the trophic groups with the dominance of zoophagous species (48.48%); however, the most numerous (quantitatively abundant) were saprophagous. Among the collected syrphids, common and numerous species, such as: E. arbustorum (LINNAEUS, 1758), E. tenax (LINNAEUS, 1758), Episyrphus balteatus (DE GEER, 1776) and S. pipiens (LINNAEUS, 1758), as well as rare species such as Callicera aenea (FABRICIUS, 1777) (NT), Chalcosyrphus piger (FABRICIUS, 1794) (DD), Epistrophe ochrostoma (ZETTERSTEDT, 1849) (VU), Orthonevra geniculata (MEIGEN, 1830) (DD), Rhingia rostrata (LINNAEUS, 1758) (DD), Sphegina sibirica STACKELBERG, 1953 (LC) and Spilomyia diophthalma (LINNAEUS, 1758) (NT), were noted. Eleven of the collected species have been included in the Polish Red List of Endangered Species. Melangyna ericarum (COLLIN, 1946) is recorded as a new one among the Polish fauna. Numerous observations did not indicate that the area covered by the study was characterised by a significantly lower species diversity compared to other sites. In fact, the samples taken were usually characterised by a relatively high biodiversity. The obtained results may suggest that anthropogenic activities, including those leading to environmental pollution with heavy metals and to a strong transformation of natural habitats, do not completely destroy biodiversity, and in some cases leave space for nature to create habitats where even rare species of organisms such as Syrphidae can develop.

Abstract:

Agriculture holds a significant strategic position in Yangling.In crop cultivation management, the strategic use of insect natural enemies can effectively reduce the reliance on pesticides and mitigate the potential harm caused by pesticide residues. Among these natural enemies, Coccinellidae and Syrphidae are the most prevalent and valuable guilds preying on many pests including aphids, in the field. However, there was limited knowledge of the species and occurrence of Coccinellidae and Syrphidae due to a lack of systematic monitoring in Yangling farmland. In order to clarify the resources of Coccinellids and Syrphids in Yangling, we monitored these two groups using both Malaise traps and regular surveys in farmland in Yangling, Shaanxi Province from 2018 to 2022. In the past five years, a total of 914 predatory Coccinellids and 1440 Syrphids have been collected. Among Coccinellids, 22 species of Coccinellids were identified, with 16 species and 6 genera. Additionally, there were 14 species of Syrphids, with 12 species and 2 genera identified. The screening and identification of natural enemy insects were conducted by professionals to ensure data quality. This dataset provides basic data on the species, quantity, and occurrence dynamics of predatory Coccinellids and Syrphids. Moreover, it also offers a large number of natural enemy insect specimen photos, ecological photos, Malaise trap photos, specimen bottle photos, and photos of the surrounding environment. It can serve as valuable references for future endeavors aimed at the protection and utilization of predatory insects.

Abstract:

Abstract. Extensively managed grasslands, particularly in mountain regions, are considered to be one of the most diverse agroecosystems worldwide. Their decline due to land use abandonment affects the diversity of both plants and associated pollinators. Extensive grasslands constitute an important habitat type and food resource for hoverflies (syrphids); however, not much is known about the effects of abandonment on this important pollinator group. In the present study, we investigated how abandonment affects species richness and the composition of syrphids in mountainous meadows. We recorded the richness of vascular plants, vegetation cover, flower cover and the surrounding landscape to examine whether and how syrphids are affected by plant and landscape parameters. We investigated the species richness, abundance and species composition of syrphids by sweep netting and by using observation plots in 18 semidry meadows across two Austrian regions and one Swiss region. For each region, we selected three meadows abandoned for more than 20 years and three annually mown non-fertilized meadows. Abandonment or mowing had no significant effect on the total number of syrphid species or individuals or on the number of aphidophagous and non-aphidophagous species and individuals. However, the total number of species and the number of non-aphidophagous species significantly increased with the increasing number of plant species. The surrounding landscape and other plant parameters showed no association with the assessed syrphid parameters. Although syrphids were unaffected by abandonment, higher syrphid species numbers in response to a higher plant richness in annual mown meadows suggest that the management of mountain meadows is beneficial in preserving syrphid richness.

Abstract:

The collection Syrphid Flies (Diptera, Syrphidae) is stored in the Podilski Tovtry National Nature Park, has more than 3,500 specimens and is replenished with new specimens every year. From 2019 to 2021 the collection is supplemented by 349 specimens. The annotated list of Syrphid Flies in the collection includes 183 species. It is based on the meeting of 2005-2013. Out of more than 3,500,000 specimens, 1,753 were collected on the territory of the Podilski Tovtry National Park. A feature of the national park is its location in one of the most densely populated regions of Ukraine. At the same time, the national park combines unique natural landscapes and anthropogenically transformed areas, which are mainly involved in agriculture. Collections of Syrphid Flies are carried out according to the standard method of entomological net in the main types of biotopes of the national nature park - forest habitats and edges, meadow-steppe habitats and shrub xerothermic areas, mesophytic meadows, cultivated biotopes. As of 2012, the list of Syrphid Flies of the Podilski Tovtry National Nature Park included 109 species from 28 genera. An updated Checklist of hover flies (Diptera, Syrphidae) for the «Podilski Tovtry» national nature park since 2012 is provided. At the end of 2021 the fauna of hover flies has 125 species from 41 genera. The most diverse in species composition are the genera Cheilosia – 29 species; Eristalis – 10 species; Eupeodes – 7 species; Chrysotoxum – 7 species, other genera include only up to 5 species. For the first time since 2012, 16 species have been identified for the Park: Brachypalpus laphriformis (Fallen, 1816); Ceriana conopsoides Linnaeus, 1758; Chalcosyrphus nemorum (Fabricius, 1805); Cheilosia urbana (Meigen), 1822; Cheilosia semifasciata Becker, 1894; Cheilosia vicina (Zetterstedt), 1849; Chrysotoxum verralli (Collin), 1940; Epistrophe ochrostoma (Zetterstedt), 1849; Meliscaeva cinctella (Zetterstedt), 1843; Merodon analis Meigen, 1822; Microdon analysis (Maquart, 1842); Pipiza lugubris Fabricius, 1775; Pipizella vidiata (Linnaeus), 1758; Platycheirus ambiguus (Fallen), 1817; Spilomyia saltuum (Fabricius), 1794; Temnostoma bombylans (Fabricius), 1805; Temnostoma meridionale Krivosheina & Mamayev, 1962 (RedBook, 2021); Volucella inflata (Fabricius, 1775); Xanthogramma stackelbergi Violovitsh, 1975.

Abstract:

With nearly 300 described species, Ocyptamus Macquart, 1834 is the second most speciose genus of Syrphidae in the New World, and the most diverse genus of Syrphinae. Ocyptamus as a whole was last revised in the late 1940’s, with many new species described after that. The genus is here placed under phylogenetic scrutiny using molecular characters from regions of the mitochondrial 12S, COI and CytB genes, and the nuclear AATS, CAD and 28S genes. Ocyptamus is shown to be paraphyletic with regard to Eosalpingogaster Hull, 1949 and Toxomerus Macquart, 1855. Several infra-generic taxa are supported as monophyletic and new arrangements are proposed. The relationships established in this paper indicate that there is a need for changes to the generic classification of the group.

Abstract:

AbstractCyclorrhaphan Diptera are an extremely successful clade of ecologically and phylogenenetically important flies. Despite their significance the relationships among lower cyclorrhaphans ('Aschiza') remain controversial in spite of several morphologically based phylogenetic analyses. We sequenced a 2.7-kb fragment of 28S rDNA for taxa representing all lower cyclorrhaphan families (except Ironomyiidae), four schizophoran families, and seven empidoid out-group taxa. Phylogenetic analysis of these data strongly supports a monophyletic Cyclorrhapha (including the enigmatic taxon Opetia nigra) that is divided into two clades - a well-supported Eumuscomorpha (Syrphidae + Pipunculidae + Schizophora), and a weakly-supported Platypezoidea (all non-Eumuscomorpha). Consequently, the former grouping known as Aschiza, which included syrphids and pipunculids, is not a valid monophyletic clade. Within Platypezoidea, most of our analyses place Lonchopteridae as sister group to Opetiidae, and strongly support the monophyly of Sciadoceridae + Phoridae. Among the Eumuscomorpha we do not recover the monophyly of Syrphoidea (Syrphidae + Pipunculidae). Instead, all analyses place Pipunculidae as the sister group to Schizophora. This novel finding has never been proposed based on morphological data and will require more data (both molecular and morphological) and taxa to confirm.

Abstract:

Syrphid flies are an important clade of pollinators, and predators on several insect groups. The oldest record of its stem lineage is late Cretaceous, but this family really diversified during the Eocene-Oligocene, with a rather sparse fossil record. Here we describe from the Baltic amber the new genus and species Eoxanthandrus garroustei gen. et sp. nov., the first fossil representative of the Syrphinae ‘group’ Bacchini and Melanostomini. Its closest extant relatives prey on caterpillars, while the other Syrphinae generally prey on Hemiptera. This specialized biology possibly dates back to the middle Eocene.

Abstract:

Syrphidae, more commonly known as flower flies, are considered one of the most important Diptera families worldwide because of their critical role in pollination, biological control and decomposition of organic matter. The study of these flies in Chile has stagnated due to a lack of local experts as well as the absence of an updated catalog of species. This study is an attempt to remedy the latter of these issues by providing an illustrated and updated catalog to the Syrphidae of Chile. Species are presented under currently accepted names, with synonyms and previous combinations listed and original references. Type localities, world and Chilean distribution by geopolitical Chilean regions, taxonomic and biological notes, a complete record of bibliographic references and extinction risk under IUCN Red List criteria are provided. This catalog recognizes 132 species of Syrphidae, belonging to four subfamilies (Eristalinae, Microdontinae, Pipizinae and Syrphinae), 13 tribes and 47 genera. A total of 46 species (34.84 %) is restricted to the geopolitical territory of Chile. Eight species are considered exotic, one is considered incertae sedis and three are based on doubtful records. Seventeen species of 10 different genera (Copestylum Macquart, 1846; Dolichogyna Macquart, 1842; Eosalpingogaster Hull, 1949b; Eupeodes Osten Sacken, 1877; Meromacrus Rondani, 1848; Palpada Macquart, 1834; Paragus Latreille, 1804; Sphiximorpha Rondani, 1850; Sterphus Philippi, 1865 and Toxomerus Macquart, 1855) are reported from Chile for the first time. A total of 44 species (33.33 %) reported from Chile are directly threatened by human activities such as agriculture, forestry, mining and/or urbanization and indirectly by climate change. The gaps found in the geographic distribution of Chilean flower fly species and what it means for its use by disciplines such as ecology, floral biology and agronomy, are discussed. In addition, the use of this illustrated catalog for biological conservation, the potential definition of priority areas and ecosystem management plans based on this group of Diptera are also discussed.

Abstract The insecticidal and antifeedant effects of aqueous extracts from two common plants (black alder Alnus glutinosa and elder Sambucus nigra) on the occurrence of Brevicoryne brassicae, its parasitoid Diaeretiella rapae and predatory Syrphidae on white cabbage were investigated in 2008-2009. Both extracts reduced the number of cabbage aphids, although the Sambucus nigra extract proved to have a better effect. Differences were seen both in the numbers of winged aphids settling on plants and in the overall numbers of aphids on plants during the entire season. There were no significant differences in the degree of parasitization by Diaeretiella rapae in the three experimental combinations. Eight species of Syrphidae were found in the Brevicoryne brassicae colonies: Episyrphus balteatus, Sphaerophoria scripta, S. rueppelli, S. menthastri, Eupeodes corollae, Scaeva pyrastri, Scaeva selenitica and Syrphus vitripennis. The dominant species was Episyrphus balteatus. The largest numbers of syrphid larvae and pupae were collected from cabbage aphid colonies on the control plants. Smaller numbers were recorded on the plot where the cabbages were sprayed with the Sambucus nigra extract. The results of this study indicate that botanical insecticides based on S. nigra have the potential to be incorporated into control programmes for the cabbage aphid.

Abstract:

Tobacco is a pillar industry in Enshi City, Hubei Province. However, in recent years, the increasing impact of diseases and pests on the yield and quality of tobacco leaves has been growing in Enshi due to climate change and the expanding scale of agricultural planting. Making good use of natural enemies is crucial for implementing green pest control and effectively reducing the negative effects of pesticides, which holds great significance for the sustainable development of the environment in Enshi. Coccinellids and Syrphidae, as important natural enemy resources, exhibit great potential for natural pest control. In order to evaluate the species and population dynamics of Coccinellids and Syrphidae in Enshi, we collected data on natural enemy insect resources from Enshi’s tobacco fields from late 2018 to late 2021 in the paper. All the data were obtained from five Malaise traps. The research covers the specimens of 1,079 predatory Coccinellids and 4,286 Syrphidae. Among them, 26 species of Coccinellids were collected, with 20 species and 6 genera identified. Additionally, there were 23 species of Syrphidae, with 18 species and 5 genera identified. The screening and identification of natural enemy insects were completed by professionals to ensure the data quality. The dataset provides information on the species, quantity, and different parts of the species of Coccinellids and Syrphidae natural enemies, along with specimen bottle photos. It can serve as theoretical basis for implementing comprehensive pest control strategies and using the natural enemy resource in tobacco fields.

Abstract:

The morphology of the metathorax of brachyceran Diptera is examined, particularly the metapleuron in the superfamily Syrphoidea comprising two families Syrphidae and Pipunculidae. The homologies of the metepisternum (EPS) and metepimeron (EPM) are redefined based on the metapleural suture (PlS), which bears an internal apophysis. A new interpretation of the metathorax is provided for Syrphidae. Members of Schizophora and Pipunculidae have an articulation between EPM and the first abdominal tergite in common and the (metapleural-abdominal) articulation is indicated as a synapomorphy for them. In some species of Syrphidae the well-developed metapostnotum is articulated with the first abdominal tergite and the (metapostnotal-abdominal) articulation is diagnostic of a subgroup of the family. The articulations are evaluated and discussed with respect to abdominal flexion of Diptera.

Abstract Ornidia obesa F. (Diptera: Syrphidae) is usually neglected in forensic entomology, although adults are rather frequent on vertebrate carrion. In this study, conducted in southeastern Brazil in 2008, we used two pig carcasses, one killed by cocaine overdose and the other by shooting, to evaluate mainly the possible influences of the type of death on the larval development of O. obesa in the pig remains. We recorded the breeding of 218 adult specimens of this syrphid fly from the carcass killed by shooting, and none from the carcass killed by cocaine. These observations may open a new perspective for the use of O. obesa in forensic studies, considering its breeding preferences and its complete development on vertebrate carrion.

Abstract:

The exotic syrphid Eumerus strigatus (Fallén) is reported for the first time in Argentina. Individuals of this species were captured in two sites distant more than 1,000 km (Villalonga, province of Buenos Aires, and Pocito, province of San Juan) associated with onion crops (Allium cepa L.). We propose the monitoring of this phytophagous hover fly because of its potential risk for this important horticultural crop

Abstract:

Photoselective nets have proven to be effective for aphid pest control as they limit their dispersal ability. However, little is known on the impact of such nets on natural enemies of aphids. In this work, we study the effect of UV-absorbing nets on the syrphid fly Sphaerophoria rueppellii Wiedemann (Diptera: Syrphidae), a commercially available aphid biocontrol agent in Mediterranean horticultural crops. First, we released mature syrphid adults and evaluated density and dispersal of the resulting immatures in a turnip crop grown under either UV-blocking (Bionet) or standard net. Second, we assessed, under controlled conditions, the impact of UV radiation on fitness-related parameters, and on flight behavior of S. rueppellii adults. Results showed that, while syprhid immature density was higher, their dispersion was reduced under Bionet. UV-absorbing nets are known to influence the dispersion pattern of aphids, which may have indirectly conditioned the distribution of their predator S. rueppellii. On the other hand, the type of net had no influence on the performance of adults. We conclude that the use of photoselective nets and the release of syrphid predators such S. rueppellii are compatible strategies to be used in IPM aphid-control programs.
