Efficiency of colored modified box traps for sampling of tabanids

Abstract

The efficiency of ten differently colored modified box traps for collecting tabanids was studied in the Monjoroš Forest in eastern Croatia. A total of 5,436 specimens belonging to 16 species of tabanids grouped into six genera were collected. The genus Tabanus was the most represented with 98% of all collected tabanids. Tabanus bromius comprised 90% of tabanids collected, and was the most abundant species collected in all box traps. The majority of tabanids (74%) were collected from black, brown, bordeaux, red, and blue traps (dark group), whereas 26% were collected from green, light violet, white, orange, and yellow traps (light group). The black modified trap was the most successful and collected 20% of all collected tabanids, whereas the yellow trap was the least effective with 1%. The number of collected specimens of species T. bromius differed significantly between the dark and light group of traps. Traps with lower reflectance from green color collected 77% of T. bromius. The most species of tabanids (12) was collected in the brown trap, whereas the least number of species (6) was collected in the yellow trap.

Efektifitas Penggunaan Manitoba Trap dalam Surveilans penyakit Bersumber Lalat di Kabupaten Tanah Bumbu, Kalimantan Selatan

“…Lembaga pangan dunia (FAO) melaporkan sebaliknya bahwa petani dan peternak lebih suka menggunakan perangkap lalat maupun serangga lain dari botol yang dibuat sendiri dengan alasan lebih murah. 21 22 juga mengungkapkan bahwa box trap yang dikembangkan dari bentuk manitoba trap dengan warna gelap khususnya hitam lebih efektif digunakan untuk menangkap lalat kelompok tabanidae. Hal serupa terjadi pada penelitian di Canada yang memodifikasi Manitoba Trap dengan plywood yang dicat.…”

Comparative efficiency of traps for horse fly (Diptera: Tabanidae) survey in riparian oak-ash forests in Danube floodplain

“…1A). The painting of the traps and the quantitative assessment of colours was performed according to the methods described in Krčmar et al (2014).…”

“…Recently, traps based on the attraction of horse fl ies to horizontallypolarized light have been developed (Horváth et al, 2008;Blahó et al, 2012). Odour-baited sticky boards are traps based on attraction (Hall et al, 1998) and traps with electric grids are based on fl ight interception (Muzari et al, 2010) or may be associated with a visual or odour attractant (Krčmar et al, 2014). An optimal survey trap for all horse fl ies species is diffi cult to achieve (Gibson & Torr, 1999) because different trap types may capture different numbers of individuals and species (Mihok et al, 2006;Krčmar & Rupnik Poklukar, 2011).…”

Very few studies measuring trap effi ciency with horse fl ies have been completed (Mihok et al, 2006;Mihok & Carslon 2007;Van Hennekeler et al, 2008;Krčmar et al, 2014). Nzi, Box and Canopy traps have been used for catching horse fl ies in different fi eld studies (Krčmar et al, 2006(Krčmar et al, , 2010(Krčmar et al, , 2014Baldacchino et al, 2013), but a comparison and evaluation of trap efficiency has never been tested.…”

Horsefly reactions to black surfaces: attractiveness to male and female tabanids versus surface tilt angle and temperature

“…Blood-sucking horseflies prefer warmer (sunlit, darker) host animals against colder (shady and/or brighter) ones and generally attack them in sunshine (Tashiro and Schwardt 1953;Bracken and Thorsteinson 1965;Horváth et al 2010aHorváth et al , 2019Blahó et al 2012bBlahó et al , 2013Egri et al 2012b;Krcmar et al 2014). But if a surface is too hot for a horsefly, it may leave the surface promptly after landing and search for a more appropriate host.…”
