Abstract

of Eumegacetes medioximus (Digenea: Eumegacetidae) in larvae of Odonata from Brazil. Biota Neotrop. 13(2): http://www.biotaneotropica.org.br/v13n2/en/abstract?shortcommunication+bn03913022013Abstract: During studies on the participation of larval Odonata in the life cycle of trematodes carried out at the Pampulha reservoir, Belo Horizonte, State of Minas Gerais, Brazil, between May and September 2011, dragonfly larvae, Orthemis discolor (Burmeister, 1839) and Perithemis mooma Kirby, 1889, were found harboring metacercariae identified as Eumegacetes medioximus Braun, 1901. This is the first report and morphological description of metacercariae of E. medioximus in the Neotropical region.

Helminth endoparasites of black drongo, Dicrurus macrocercus (Passeriformes: Dicruridae) from Chattogram, Bangladesh

“…Several digenean such as the species that parasitize birds and amphibians, have been reported parasitizing dragonfly larvae as second intermediate or paratenic host (Stafford 1931, Snyder and Janovy Jr 1994, Kumari and Madhavi 1994 and these helminths have also been recorded as adult parasites in various vertebrate hosts (Travassos et al 1969). Pinto et al (2013) for the first time reported metacercariae, identified as Eumegacetes medioxiums, in case of natural infection of larval dragonflies in the Neotropical region. From food analysis of Black Drongo, it was found that the larvae and adults of odonatan constituted a considerable portion in their food items.…”
