Parasitoids of Ophyra aenescens (Wiedemann) (Diptera: Muscidae): fly of medical-sanitary importance collected in State of Goiás, Brazil

Abstract

The objective of the study was to report the first occurrence of the parasitoid Brachymeria podagrica in pupae of Ophyra aenescens, a fly of medical-sanitary importance. Human feces was used as bait to collect the insects. In the study 20 pupae of Ophyra aenescens (Wiedemann) (Diptera: Muscidae) were obtained, of which 20% of the total yielded the parasitoid Brachymeria podagrica (Hymenoptera: Chalcididae). Key-words: Medical-sanitary importance. Synanthropy. Parasitoid. Muscoid fly.Resumo O objetivo do presente estudo é relatar a primeira ocorrência do parasitóide Brachymeria podagrica como inimigo natural de Ophyra aenescens, mosca de importância médico-sanitária. Para coleta dos insetos foi utilizado como isca fezes humanas. Obtiveram-se 20 pupas de Ophyra aenescens (Wiedemann) (Diptera: Muscidae), das quais 4 emergiram parasitóides pertencentes à espécie Brachymeria podagrica (Hymenoptera: Chalcididae), apresentando uma incidência de parasitismo de 20,0%.

Withdrawn

“…Species of the genus Brachymeria Westood are important primary parasitoids of couscoid dipterans, such as those of the family Sarcophagidae (Burks, 1960;Habu, 1960;Grissel & Schauff, 1990;Marchiori, 2001) and Calliphoridae (Bishop et al, 1996). Some species are of economic importance because they attack insect pests and others of forensic importance (Gauld & Bolton, 1988;Santana et al2008 Squamatoids trivittatus (Curran, 1927) (Diptera: Sarcohagidae) (Silva, 1999;Marchiori et al, 2001a;Marchiori et al, 2002a;Marchiori et al, 2003a;Silva et al, 2005).…”

FIRST RECORD OF Brachymeria podagrica (HYMENOPTERA: CHALCIDIDAE) AS PARASITOID OF Peckia collusor (DIPTERA: SARCOPHAGIDAE)

“…The genus Brachymeria Westwood includes about 350 described species worldwide (Noyes, 2019), with 37 species in the Neotropical Region (Delvare and Huchet, 2017). Brachymeria species are significant parasitoids of calyptratae flies, such as Sarcophagidae, Calliphoridae and Muscidae (Marchiori et al, 2002a;Marchiori et al, 2002b;Marchiori et al, 2003;Marchiori, 2004;Marchiori and Silva Filho, 2004;Couri et al, 2006;Oliva, 2008). Most species are solitary endoparasitoids with a koinobiont strategy.…”
