Seasonal Abundance of Deer and Horse Flies (Diptera: Tabanidae) in the Northern Part of Gyeonggi-do,Republic of Korea

The seasonal abundance of horse and deer flies (family Tabanidae) was analyzed using Mosquito Magnet^® traps at 5 sites located near/in the demilitarized zone, northern Gyeonggi-do, Republic of Korea from late April to early October for 4 consecutive years (2010-2013). A total of 2,999 horse and deer flies (tabanids) belonging to 5 genera and 20 species were collected. Chrysops mlokosiewiczi (90.9%) was the most frequently collected, followed by Haematopota koryoensis (4.8%) and C. suavis (1.0%). The remaining 17 species comprised only of 3.3% of all species collected. C. mlokosiewiczi demonstrated bimodal peak populations during mid-June and early August, while H. koryoensis demonstrated a unimodal peak during mid-July. Overall numbers of tabanids collected were influenced by the previous year’s winter temperatures and precipitation. Population abundance was influenced by habitat with most of tabanids collected from habitats near forested areas, followed by rice paddies, and a beef farm.     

Tabanid Flies (Diptera: Tabanidae) of the Northern Part of Gyeonggi Province, Republic of Korea

Tabanid flies were surveyed using New Jersey light traps and Mosquito Magnet® traps at US Army installations and training sites in the northern part of Gyeonggi Province, Republic of Korea. A total of 344 tabanid flies, comprising 14 species and 5 genera, were collected from June to August during 2003‐2004. Dominant species were Chrysops vanderwulpi (57.3%), Haematopota sinensis (29.1%), Haematopota koryoensis (4.4%) and Tabanus mandarinus (2.3%). Mosquito Magnet traps that generated CO₂through the combustion of propane gas were nearly 6 times more effective in collecting tabanid flies than New Jersey light traps. Based on Mosquito Magnet trap collections, peak populations occurred from mid‐June to early July.;     

Preliminary list of horse flies (Diptera, Tabanidae) of Serbia

Thirty six species of horse flies (Tabanidae) were previously known from Serbia (Europe). The present faunistic study of horse flies (Tabanidae) has resulted in the recording of the 4 new species Atylotus fulvus (Meigen, 1804); Tabanus miki Brauer in Brauer and Bergenstamm, 1880; Tabanus unifasciatus Loew, 1858; and Heptatoma pellucens (Fabricius, 1776), in the fauna of Serbia. The genus Heptatoma Meigen, 1803 is cited for the first time in the fauna of Serbia. 40 species are currently known from Serbia, belonging to nine genera. The fauna can be considered relatively poorly studied. Most of the species belong to the Boreal-Eurasian type of fauna 23, followed by the South European group with 8 species, the Mediterranean group with 6 species, European group with 2 species and Central European group with 1 species.

Taxonomic Revision of Tabanus mandarinus Species Group (Diptera: Tabanidae) from Korea

ABSTRACT In a review of the horseflies of the Tabanus mandarinus species group in Korea, six species are recognized. Among them, Tabanus nipponicus is newly recorded from Korea. Keys, annotated check lists of domestic records, collection data, and photographs of T. nipponicus are provided.     

Distribution of halophilous species of horse flies in Croatia (Diptera: Tabanidae)

In the past 20 years, fauna and ecology of horse flies (Tabanidae) were intensively studied in Croatia, especially in the Ramsar sites as wetlands of international importance. Different habitat requirements of larvae were recognised and adults of 78 species in 10 genera were recorded. The true aquatic and semiaquatic larvae are represented by several species of the genera Chrysops Meigen, 1803 Hybomitra Enderlein, 1922. Some species from this ecological group are typical inhabitants of saline biotopes. In the Croatian fauna three halophilous species were recorded: Chrysops italicus Meigen, 1804, Hybomitra acuminata (Loew, 1858) and H. expollicata (Pandellé, 1883). The distribution of these species in Croatia covers 7, 17 and 3 UTM (Universal Transverse Mercator) grids, respectively. Specimens were primarily collected in habitats with brackish water along the Adriatic coast, such as Vransko Lake, the mouth of the River Cetina, the delta of the River Neretva and Mljet Island. Only specimens of H. acuminata were recorded in the continental part of Croatia. They were sporadically collected on localities along the Danube floodplain and on four localities near the river Drava. The distribution of H. acuminata in the continental part indicates otherwise rare saline habitats along the Drava and Danube rivers (1.38% of the total catch of the Hybomitra – species from the floodplain).     

An annotated checklist of the horse flies (Diptera: Tabanidae) of Lebanon with remarks on ecology and zoogeography: Pangoniinae and Chrysopsinae

Knowledge of the horse fly fauna (Diptera: Tabanidae) of Lebanon is fragmentary, while the local fauna of most neighboring countries has been fairly well researched. Within the framework of the 20-year project "The ecology and zoogeography of the Lepidoptera of the Near East," we regularly collected biting flies in the whole region, including Lebanon. During this time we recorded 14 horse fly species for two subfamilies in Lebanon: four Pangoniinae and ten Chrysopsinae. Only a single species, Chrysops flavipes Meigen, 1804, was known previously in Lebanon, but the following four Pangoniinae: Pangonius haustellatus (Fabricius, 1781), Pangonius obscuratus Loew, 1859, Pangonius argentatus (Szilady, 1923), and Pangonius fulvipes (Loew, 1859) and nine Chrysopsinae: Silvius appendiculatus Macquart, 1846, Silvius ochraceus Loew, 1858, Nemorius irritans (Ricardo, 1901), Nemorius vitripennis (Meigen, 1820), Chrysops buxtoniAusten, 1922, Chrysops compactusAusten, 1924, Chrysops caecutiens (Linnaeus, 1758), Chrysops italicus Meigen, 1804, and Chrysops hamatus Loew, 1858 are new records for the Lebanese fauna. The Tabanidae fauna of Lebanon is completely Palearctic and most species are of a Mediterranean distribution type. Lebanon or nearby northern Israel appears to be in the Levant, the southern geographical distribution border for the Pangoniinae and Chrysopsinae.     

Population dynamics of mosquitoes (Diptera: Culicidae) and their disease-harboring rates in Gyeonggi province,South Korea

Population dynamics and species composition of mosquitoes were monitored in a suburban residential area and rural areas, including a migratory bird refuge area and a cattle farm area, from 2017 to 2019. Mosquitoes were collected every two weeks using one BG sentinel trap and two black-light traps in a suburban residential area and a migratory bird refuge area, and one black-light trap in a cattle farm area from March to November. From the surveillance, a total of 13,267, 9,697 and 6,688 mosquitoes were collected in 2017, 2018, and 2019, respectively. The peak of the mosquito population was observed in August and September in both the suburban residential area and rural areas. In general, Culex pipiens pallens was the dominant species in the suburban residential area, whereas Aedes vexans nipponii and Anopheles spp. were the most dominant in the rural areas. Collected mosquitoes were pooled into groups for each collection site and species to investigate flavivirus harboring. Three pools were positive for Japanese encephalitis virus type V, one pool was positive for Chaoyang virus, and six pools were positive for Culex flavi virus from the 731 pools tested. When total numbers of collected mosquitoes were further analyzed by linear regression analysis for their interaction with ambient temperature and relative humidity, the number of mosquitoes were significantly affected by the ambient temperature. In contrast, relative humidity was significantly affecting the total number of mosquitoes only for the migratory bird refuge area.     

The orientation of horse flies and deer flies (Tabanidae, Diptera): I. The attractance of heat to Tabanids

Tabanid flies display an exceptionally strong tendency to orientate to and congregate in enclosures which accumulate heat during daylight. In order to study this behaviour to the best advantage and perhaps also to exploit it toward practical control a helio-thermal trap was designed and tested. This trap converts solar radiation to heat and is so designed that tabanids collect in a killing bottle. A number of ecological, ethological and practical applications of the trap are discussed in the light of data obtained to date.

Résumé Plusieurs espèces de tabanides semblent être fortement attirées par une source de chaleur sensiblement plus élevée que celle de la temperature ambiante. Ces espèces se comportent ainsi surtout quand il fait très chaud alors qu'elles sont tout particulièrement actives. Nous avons profité de ce comportement pour construire un piège hélio-thermique ainsi appelé parce qu'il produit une chaleur tirée de l'énergie solaire.Les tabanides attirés par ce piège y pénètrent par la partie inférieure, et, apparemment attirés par phototaxis volent vers le sommet. Dans cet espace la temperature s'élève audessus de la limite tolérable et les tabanides sont abrutis par la chaleur. Alors ils tombent par un entonnoir dans un récipient contenant du cyanure. Les tabanides capturés sont exclusivement des femelles: fait de la plus haute importance dans l'emploi pratique de ce piège.Cependant ce piège a d'autres applications comme instrument de recherches entomologiques pour les taxonomistes, les oecologistes et les éthologues. Il est fort probable qu'un simple dispositif de moulinet actionné par le vent et créant un mouvement rotatoire augmenterait son attraction sur les tabanides et augmenterait sa valeur pratique aussi bien que sa valeur scientifique. Uu autre emploi important résulterait de son adaptation à l'étude des substances qui attirent ou repoussent ces insectes.

     

Species diversity and abundance of Tabanus spp. (Diptera: Tabanidae) in different habitats of Thailand

Tabanus spp. or horse flies (Diptera: Tabanidae) are haematophagous flies of medical and veterinary importance. They are known to cause trypanosomosis or surra in domestic and wild animals in Thailand. This study conducted an entomological survey of horse flies from different sites in Thailand. Horse flies were collected from three different habitats: primary forests, secondary forests and villages using Nzi traps between April 2012 and December 2016. A total of 1835 female horse flies were collected and 45 species were identified. The five most abundant species were T. striatus (25.45%), followed by T. megalops (21.36%), T. rubidus (14.82%), T. tamthaiorum (7.90%) and T. oxybeles (6.38%). The highest proportion of horse flies was collected in villages (39.13%), followed by primary forests (34%) and secondary forests (26.87%). The species diversity of horse flies in primary forests was higher than in other habitats. The results of this study may be used for a horse fly control program.     

Seasonal abundance of horse flies (Diptera: Tabanidae) from two locations in eastern Croatia.

A total of 10,539 tabanid horse flies from 22 species and five genera was collected in the Tikves forest within the Kopacki rit Nature Park in eastern Croatia. Seasonal abundance was analyzed for the six most abundant species. Tabanus maculicornis, Tabanus tergestinus, and Haematopota pluvialis reached their highest peak abundance in the fourth week of June. Atylotus loewianus and Tabanus bromius reached their highest peak of abundance in the first week of August, whereas Tabanus sudeticus reached its maximum abundance in the third week of July. Horse flies also were collected once a week on the pasture at Petrijevci from mid-May to mid-September during 1993. Paired collections were made from a Malaise trap and from a horse by using a sweep net. A total of 2,867 tabanids belonging to 26 species was collected. The number of tabanids collected on horses was much higher than the total captured with Malaise traps. On their natural host (horse), 2.6 times more tabanids were collected than in the traps. Seasonal abundance was analyzed only for the eight most abundant species. Chrysops paralellogrammus, Tabanus autumnalis, Tabanus bromius, Tabanus tergestinus, Haematopota pluvialis, and Haematopota subcylindrica all reached their highest peak of abundance in the second week of July, whereas Tabanus maculicornis reached the maximal peak of abundance in the third week of June. Seasonal meteorological variability that occurs periodically from one year to another has a significant influence on the maximal peaks of tabanid abundance.     

Systematics and distribution of horse flies (Diptera: Tabanidae) of Jordan.

The horse fly fauna of Jordan consists of 24 species belonging to seven genera. The present study adds two new records; Tabanus unifasciatus and Tabanus lunatus. Keys and illustrations for the horse flies of Jordan are presented based on examined materials. Distribution and geographic ranges for each species is also given.     

The orientation behaviour of horse flies and deer flies (Tabanidae: Diptera) IV. The influence of some physical modifications of visual decoys on orientation of horse flies

It was shown that the orientation of adult tabanids to visually attractive glossy black targets is little influenced by temperature and wind-actuated movement of the targets. The size of the targets was critical only for small targets provided that the black silhouette area was reduced without dappling or without striping by light-coloured areas.

Die orientierung der bremsen (Tabanidae: diptera). IV. Der einfluss einiger physikalischer veränderungen der optischen ziele bei der orientierung der bremsen

Zusammenfassung Es wurde gezeigt, dass die Orientierung von Tabaniden-Imagines auf hoch attraktive, glänzende, schwarze Ziele durch die Temperatur und Bewegung der Ziele wenig beeinflusst wird. Die Grösse der Ziele war nur bei kleinen Ziel kritisch, vorausgesetzt dass die Fläche der schwarzen Silhouette nicht durch weiße Fleckung oder Streifung verkleinert wurde.

     

Alighting sites of female Tabanidae (Diptera) at Rekomitjie, Zimbabwe

Twenty-one species of Tabanidae from four genera were recorded. Where samples were large enough, the preferred alighting sites were determined for the tabanids, and differences in such sites were found for species in three genera. The lower legs of the bait ox were the preferred alighting site for 61.8% of the flies. In the season of peak fly numbers, the bait ox was under stress from the tabanids.

New records for the horse fly fauna (Diptera: Tabanidae) of Jordan with remarks on ecology and zoogeography

The horse fly fauna (Diptera: Tabanidae) of Jordan is, after Israel, the richest in the Levant, with 24 known species. During the 20-year project "The Ecology and Zoogeography of the Lepidoptera of the Near East," we regularly collected blood-feeding flies, resulting in 11 additional species of Tabanidae for Jordan. The new records are: Atylotus quadrifarius (Loew, 1874), Chrysops caecutiens (Linnaeus, 1758), Dasyrhamphis nigritus (Fabricius, 1794), Haematopota pallens Loew, 1871, Nemorius irritans (Ricardo, 1901), Philipomyia graeca (Fabricius, 1794), Tabanus cordiger Meigen, 1820, Tabanus taeniola Palisot de Beauvois, 1806, Tabanus quatuornotatus Meigen, 1820, Tabanus separatus Effllatoun, 1930, and Tabanus spectabilis Loew, 1858. Most of the new records (10/11) are of Palearctic origin; of these, six are of a Mediterranean and one each of West Palearctic, Euroasiatic, Irano-Turanian, and Eremic providence. Only one species, T. taeniola, is an Afrotropical-Eremic element.
