“…Os tabanídeos podem ser facilmente coletados utilizando animais domésticos ou silvestres como isca devido à sua busca ativa por hospedeiros e excelente capacidade de vôo. Todavia, essa técnica de coleta pode apresentar limitações pela especifi cidade de tabanídeos por hospedeiros (Ferreira et al 2002, Limeira-de-Oliveira et al 2002, Ferreira 2003, Ferreira & Rafael 2004) ou porque algumas espécies habitam o dossel da fl oresta (Rafael & Gorayeb 1982, Gorayeb 1985, 1999, Henriques 2004.…”

-Adults of Tabanidae may become serious pests wherever they occur due to their attack to humans and others animals. Tabanids were captured near ground, water surface and at 25 m high on primary forests and forest gaps of anthropogenic origin, to understand their abundance, seasonality, diversity and similarity on such environments. Collections were carried out in the Base II of the War Instruction Center in the Jungle (CIGS) located at 54 km from Manaus municipality, Amazonas state. Two Malaise fl ight interception traps and four attraction traps (two suspended at 25 m high and two above the water surface of igarapé) were installed in forest gap and primary forest, areas for 10 consecutive days, during 15 months. A total of 2,643 specimens of 66 species were captured. Diachlorini (35 species /11 genera) was the most abundant tribe, followed by Tabanini (19 species /three genera), Chrysopsini (seven species /one genus) and Scionini (fi ve species /two genera). Seventeen species were captured only in the primary forest, 11 in the anthropic clearing, and 38 species were common to both environments. The most abundant species were Phorcotabanus cinereus (Wiedemann), Tabanus occidentalis L, Chrysops laetus Fabricius and Tabanus angustifrons Macquart. The greatest richness was found in drier months (September/October) in both areas. The forest gap showed higher abundance of specimens (1,827) than the primary forest (816). Traps suspended above the water surface were the most effi cient (1,723 specimens) probably due to the dispersion of horsefl ies over small streams.

“…Female horse ies are typically facultative and can opportunistically consume blood, nectar and pollen to ful ll their energy requirements for ight, reproduction and oviposition (Leprince et al 1983;Karolyi et al 2014;Mullens 2019). Some of their prey, including mammals, reptiles and birds, exhibit evasion and defense behaviors to avoid horse y bites (Limeira de Oliveira et al 2002; Barros and Foil 2007;Caro et al 2014;Altunsoy 2015), indicating that the foraging behavior of female horse ies can be energetically demanding, therefore, the blood intake provides them with advantages such as increased escape speed ). This energetic investment in foraging would enhance the likelihood of encountering prey due to an increase in ight frequency; however, it would also raise the probability of being captured in Malaise traps.…”

Male horseflies have low capture rates in Malaise traps, a widely documented pattern observed in numerous ecological studies. We present findings from a specific locality in Ecuador where a departure from this established pattern is observed. In this locality, males accounted for 59.14% of Tabanidae captures. The disruption in capture patterns observed using Malaise traps represents an uncommon feature in the scientific literature and during collections conducted over eight years in Ecuador. Despite the inherent limitations of Malaise traps in capturing male horseflies, it is possible that under specific conditions, such as the presence of optimal aggregation areas for horseflies, Malaise traps may enhance the capture efficiency of males. Additionally, we provide a detailed discussion on the disruption and disparity in capture sex proportions in Tabanidae, commonly reported in the scientific literature. Understanding these aspects of tabanid behavior is essential due to the outbreaks and deaths associated with trypanosomiasis infections in Ecuador.

“…Females often require blood meal for maturation of eggs, at least after the first posture, so they are considered autogenous, partially autogenous, or nonautogenous [4]. Males are phytophagous, but females, always in search of blood, repeatedly attack humans, domestic and wild animals, among primates, rodents, alligators, snakes, turtles, and birds, especially during the drier seasons [5][6][7][8]. Tabanids are known worldwide for its painful sting and are mechanical and biological vectors of several helminths, viruses, bacteria, and protozoa, etiologic agents of diseases that can affect humans and wild and domestic animals [9][10][11].…”
