Interaction between Tephritidae (Insecta, Diptera) and plants of the family Asteraceae: new host and distribution records for the state of Rio Grande do Sul, Brazil

Abstract

A B S T R A C T Twenty species of Tephritidae (Diptera) are recorded in association with capitula of plants in the family Asteraceae. The Tephritidae genus Tetreuaresta is registered for Rio Grande do Sul for the first time. Five species of Tephritidae are newly recorded for Rio Grande do Sul, and new hosts are recorded for the following fly species: Dioxyna chilensis (Macquart), Plaumannimyia dolores (Hering), Plaumannimyia imitatrix (Hering), Plaumannimyia miseta (Hering), Plaumannimyia pallens Hering, Tomoplagia incompleta (Williston), Tomoplagia matzenbacheri Prado, Norrbom & Lewinsohn, Tomoplagia reimoseri Hendel, Xanthaciura biocellata (Thomson) and Xanthaciura chrysura (Thomson).

New distribution record, host plant and notes on natural history of Tomoplagia rudolphi (Lutz & Lima, 1918) (Diptera: Tephritidae)

“…We recorded 28 interactions between among species of 10 genera Tephritidae in flowers of Asteraceae. A previous study that inventoried Tephritidade in Passo Fundo recorded 102 species of Asteraceae in 64 genera and 29 associations between Tephritidae and host plants (Savaris et al, 2015). Our results in a less comprehensive area (Campus I only) represent 47% of the species recorded for the municipality and 96.5% of the interactions recorded by Savaris et al (2015).…”

Our results in a less comprehensive area (Campus I only) represent 47% of the species recorded for the municipality and 96.5% of the interactions recorded by Savaris et al (2015). Of the 28 insect/plant interactions recorded in this study, 27 were capitula of Asteraceae and only T. rudolphi was reared from stem, where the gall formation occurred.…”

“…The southeast region with 33 species has the greatest diversity within the genus, representing 91.6% of the species that occur in Brazil (Lima, 1934;Fernandes et al, 1988;Norrbom et al, 1999;Prado et al, 2002;Prado et al, 2004;Abreu et al, 2005). The southern region with 11 species has 30.5% of the country's species Garcia et al, 2002;Garcia, 2003;Prado et al, 2002;Prado et al, 2004;Sabedot et al, 2008;Sabedot-Bordin et al, 2011;Savaris et al, 2015). From the midwestern region only six species are reported, representing 16.6% of Brazil's species.…”

“…In Rio Grande do Sul are recorded the following species: T. brasiliensis, T. costalimai, T. fibrigi, T. formosa, T. incompleta, T. matzenbacheri Prado, Norrbom & Lewinsohn, 2004, T. minuta, and T. reimoseri, representing 72.7% of the region's species (Prado et al, 2002;Prado et al, 2004;Savaris et al, 2015). The state of Paraná has the lowest diversity with 27.2% of the species from the region.…”

“…Most species of Tomoplagia are associated with host plants of the tribe Vernonieae (Asteraceae) (Prado et al, 2002;Prado et al, 2004;Sabedot et al, 2008;Sabedot-Bordin et al, 2011;Savaris et al, 2015). There are a few records in the tribes Mutiseae, Heliantheae and rarely in other tribes of Asteraceae (Foote et al, 1993;Prado et al, 2002;Prado et al, 2004;Norrbom, 2010).…”
