First record of Trichopria anastrephae, parasitoid of fruit flies, in the Rio Grande do Sul State, Brazil

There is little information on native species of hymenopteran parasitoids of fruit flies from the Neotropical region. Collections of guava (Psidium guajava L.) were conducted from January to March 2009 at the Experimental Area of Agroecological Production studies (AEEPA), Federal University of Pelotas, Capão do Leão, Rio Grande do Sul. Fruits were taken individually to the laboratory, counted, weighed and packaged in plastic pots containing moist sand and mesh on top. Weekly substrate was sieved, the pupae collected and placed in Petri dishes with filter paper moistened with distilled water. The pupae were placed in a room (26±2°C, 60±10% RH and 12h photophase) where observations were made weekly to check the emergence of adult flies or parasitoids and subsequent species identification. Trichopria anastrephae Lima was obtained from Anastrepha fraterculus in guavas, with a parasitism rate of 5.8%.
