Sobre a ocorrência de Philornis angustifrons e P. deceptiva (Diptera, Muscidae) em ninhos de Suiriri affinis e S. islerorum (aves, tyrannidae), no cerrado do Distrito Federal, Brasil

Abstract

On the ocurrence of Philornis angustifrons and P. deceptiva (Diptera, Muscidae) in nests of Suiriri affinis and S. islerorum (Aves, Tyrannidae) in the savanna of Distrito Federal, Brazil-The first report of Philornis angustifrons and P. deceptiva infesting nests of Suiriri affinis and S. islerorum in area of Distrito Federal´s savanna is presented. It is known that larvae of these species have a strict relationship of parasitism with birds. The pupae were collected after the abandonment of the nests and the flies emerged in a period of about 13 days.

Low reproductive success of Campo Suiriri (Suiriri affinis) and Chapada Flycatcher (S. islerorum) in the central Brazilian Cerrado

“…The nests were stored in a laboratory at a mild temperature until flies emerged. The flies were identified (Higgins et al 2005) and are now deposited in the Entomological Collection of the Departamento de Zoologia, Universidade de Brasília.…”

Larvas de Philornis deceptiva Dodge & Aitken (Diptera, Muscidae) no Sanhaçu-cinzento Thraupis sayaca (Linnaeus 1766) (Thraupidae) no município de Seropédica, Rio de Janeiro, Brasil

“…Provavelmente o baixo peso oriundo do parasitismo e a alta infestação, em relação aos dois sobreviventes, tiveram uma ação direta na morte dos ninhegos (n = 4). Higgins et al (2005) descrevem a morte de ninhegos de S. islelorum devido ao acentuado parasitismo por larvas de Philornis. Couri (1985) descreveu a presença de 32 larvas de Philornis sp.…”

<b>Occurrence of Philornis bella Couri in nestlings of Tyrannus melancholicus Vieillot (Tyranninae) in the municipal district of Seropédica, Rio de Janeiro</b><br>DOI: 10.5007/2175-7925.2011v24n3p69

“…The larvae of P. bella are subcutaneous (biting), feed on blood, and are commonly found in birds that keep clean nest (HIGGINS et al, 2005). According to Guimarães and Papavero (1983), these muscidae deposit their eggs directly on the young or their nests.…”

“…However, Smith (1968) mentions that seven larvae would be enough to cause a debilitating effect on a nestling. Higgins et al (2005) also mentioned that the effect is debilitating and described the death of a nestling of S. slelorum due to severe parasitism by larvae of Philornis. Possati et al (2001) mentioned that the average number of larvae found on nestlings of P. sulphuratus was seven and that all the nestlings survived.…”
