The genus Zygothrica Wiedemann 1830 (Diptera, Drosophilidae) in Santa Catarina state, southern Brazil: distribution and ecological notes

Abstract

Doge, J.S., Gottschalk, M.S., Bizzo, L.E.M., Oliveira, S.C.F., Schmitz, H.J., Valente, V.L.S. & Hofmann, P.R.P. 1925 and Z. vittimaculosa Burla 1956. Except for Z. bilineata and Z. hypandriata, these are the new southernmost records for the geographical distribution of these species. All the collected species were represented by few individuals, probably as a consequence of the collection method, and most of them was captured in winters and springs. Five species were restricted to the more preserved studied site, and most individuals were collected in forest sites. Nevertheless, four species were also captured in urban or xeric environments, indicating a higher tolerance and a wider ecological versatility in this genus as compared to what was previously thought, at least for some species. O presente estudo reúne dados de pesquisa de nove locais de coleta no estado de Santa Catarina, sul do Brasil. Foram obtidas amostras durante aproximadamente quatro anos em áreas florestais, litorâneas e urbanas. As moscas foram atraídas através de isca de banana fermentada e capturadas em armadilhas. Dentre as espécies do gênero Zygothrica

Seasonal dynamics of a drosophilid (Diptera) assemblage and its potencial as bioindicator in open environments

“…The richness of this genus, though, is still poorly known, especially in the Neotropical region, where MEDEIROS & KLAZCKO (2004) and DÖGE et al (2008) estimated that nearly 40% of the brazilian Drosophila species are still undescribed. Even the geographical distribution of many species is still not well established (DÖGE et al, 2006(DÖGE et al, , 2007MATA et al, 2008a).…”

Living fruits of Psychotria brachyceras Müll. Arg. (Rubiaceae) as the main larval host of Zygothrica orbitalis (Sturtevant, 1916) (Diptera, Drosophilidae)

“…The highest abundance of Z. orbitalis was recorded in the months of July and August in Amazon (Santa-Brígida et al, 2019), Atlantic Forest (Monteiro et al, 2014) and Pampa Biomes (Mendes et al, 2017). Also, Döge et al (2007), who analyzed samples from Atlantic Forest areas, recorded Z. orbitalis primarily from April to September. The sampling of Z. orbitalis coincided with the ripening of P. brachyceras fruits in HBITL from May to August aligning with the described phenology of the plant.…”

“…As expected, Zygothrica orbitalis (Sturtevant, 1916) has been sporadically observed in surveys in various regions of Brazil. Most studies with banana-baited traps that have reported the presence of Z. orbitalis managed to collect only a few dozen individuals, even though tens or hundreds of thousands of Drosophilidae were sampled (De Toni et al, 2007;Gottschalk et al, 2007;Schmitz et al, 2007;Döge et al, 2007Döge et al, , 2008Bizzo et al, 2010;Poppe et al, 2014;Coutinho-Silva et al, 2017;Duarte et al, 2018). Furthermore, with studies that specifically targeted Drosophilidae associated with fungi, Z. orbitalis was seldom captured: one specimen was collected visiting Auricularia auricula-judae (Bulliard) Quélet, but there are no records of Z. orbitalis emerging from fungi, in a study carried out by Valer et al (2016) with 26 fungi species (Table S1).…”

Diversidade de drosofilídeos (Diptera, Drosophilidade) na Reserva Ecológica do IBGE, em áreas afetadas pelo fogo

“…A PERMANOVA par-a-par revelou que, em relação ao fator mensal, todas as amostras são diferentes entre si (p<0,005), mostrando que a estrutura das assembleias se altera ao longo do tempo. Zygothrica, raros para esse método de coleta com armadilhas de retenção, porém comumente associados a fungos e facilmente coletados de forma ativa (Grimaldi, 1987;Döge et al, 2007).…”
