Parasitoidism of Chalcidid wasps (Hymenoptera, Chalcididae) on Philornis sp. (Diptera, Muscidae)

As larvas de Philornis Meinert são conhecidas como parasitas de aves, com hábitos coprófagos, semi-hematófagos ou hematófagos. Dados biológicos das larvas das 50 espécies descritas são ainda pouco conhecidos. Aqui são descritos alguns aspectos do parasitismo de uma espécie de Philornis em Thalurania glaucopis Gmelin (Trochilidae) e duas espécies parasitóides de Chalcididae (Hymenoptera), Conura annulifera (Walker, 1864) e Brachymeria podagrica (Fabricius, 1787) que emergiram de pupários de Philornis sp. são registradas.

Parasitoids of the family Chalcididae colleted in pastures and forests using yellow traps, in Itumbiara, Goiás, Brazil

The objective of this study was to appraise the occurrence of parasitoids of the family Chalcididae in Itumbiara County, State of Goiás, central Brazil. Insect samples were collected in pastures and native forest areas using pan traps, from January to December 1998. The traps consisted of circular yellow plastic containers (30 cm in diameter and 12 cm in height) containing a mixture of 2 L of water, 2 ml of detergent, and 2 ml of formaldehyde. Samplings were performed weekly by placing 10 traps at soil level (5 traps in the pasture and 5 in the woods). During 1998, 121 specimens of Chalcididae were collected. Haltichella sp.4 was the most abundant species collected (15.7 percent)
