“…This indicates that the introduction of D. longicaudata in the location of the study did not harm the other native parasitoids in that environment, ratifying the results obtained in Bahia, Brazil (caRValho, 2004;BOMFIM et al, 2010) and Minas Gerais, Brazil (ALVARENGA et al, 2005), after the releases of D. longicaudata. the native species, which compete for the same resources, in this case the fruit fly larvae, specialize themselves so they can use theirs hosts in different locations of the plant, and explore different phases of the cycle of their hosts (siViNski et al,1998).…”

ABSTRACT-Diachasmimorpha longicaudata (ashmead) (hymenoptera: Braconidae) was introduced in 1994, in Northeastern Brazil, to evaluate its use in biological control programs of fruit flies. However, the effects of this specie on parasitism rates on the population of native parasitoids and fruit flies in Southern Brazil conditions are unknown. The objective of this study was to evaluate the impact of releases of D. longicaudata on the parasitism rates on loquats, peach trees, strawberry guava trees, and persimmons in an experimental area in the city of Eldorado do Sul, Rio Grande do Sul, in southern Brazil. In the first year of the study, fruits were collected and stored in the laboratory to obtain pupae. The flies or parasitoids that emerged were counted and identified. In the second year, adults of D. longicaudata were reared in the laboratory on Anastrepha fraterculus (Wied.) and larvae were released in the field (1.700 insects/ha) at each harvest time and the parasitism was evaluated in the same manner as in the first year. In the third year, the procedure was the same as the first year, without any releases. A significant increase in the rates of parasitism was recorded in the second year except in the persimmon, in which no parasitoid was recovered in any year. In the second year the number of emerged fruit flies was also lower. In the third year, no D. longicaudata were recorded and parasitism rates of parasitism were statistically similar to those found in the first year. The native parasitoids collected were Aganaspis pelleranoi (Brèthes), Doryctobracon areolatus (szépligeti), Doryctobracon brasiliensis (szépligeti) and Utetes anastrephae (Viereck). These species were found in at least one kind of fruit even in the years after the introduction of the exotic parasitoid, indicating that it was not harmful to these species. We conclude that D. longicaudata can help to reduce the population of fruit flies in Eldorado do Sul region, in Rio Grande do Sul.Index terms -biological control, Anastrepha fraterculus, Aganaspis pelleranoi, Doryctobracon, Utetes anastrephae.

“…Bomfim, Carvalho and Carvalho (2009) evaluated the frequency of parasitoids before and after 24 and 48 hours of release D. longicaudata in two locations in Bahia, and found lower frequency of the exotic parasitoid at 48 compared with 24 hours after its release. However, according to these authors, the native species D. areolatus was the most frequent before and after the release, thus, the release of the exotic species D. longicaudata had no negative effect on the occurrence of native parasitoids.…”

“…The specific identification of parasitoids was based on the differences in the alar ribs, jaws position and in the propodeum morphology, following dichotomous keys described by Canal and Zucchi (2000). Confirmation of the species was carried out by Professor Valmir Antonio Costa from the Biological Institute of Campinas SP.…”

-The objective of this work was to assess the effects of the release and establishment of the exotic parasitoid Diachasmimorpha longicaudata (Ashmead, 1905) (Hymenoptera: Braconidae) and its interspecific competitive relationship with native fruit fly parasitoids in organic and conventional orchards in Maceio, State of Alagoas, Brazil. The exotic parasitoids were reared in the Radio-Entomology Laboratory of the Center for Nuclear Energy in Agriculture, University of São Paulo, Piracicaba, São Paulo, and released (112,350 individuals between five and eight days old) in orchards from June 8 to July12, 2013.Fruit samples were collected randomly every week during one year to assess the D. longicaudata recaptured from plants and fallen fruits on the ground, which were taken to the Entomology Laboratory of the CECA-UFAL, classified and individually placed in plastic containers, containing a layer of 1 cm of sand for pupation of the host larvae. The pupae, obtained after 10 days, were placed in Petri dishes with a layer of sand until the emergence of adults, which were then kept in plastic microtubes, containing ethanol 70%. The release of exotic parasitoids did not displace native species. The same species were found before and after the release in both cultures: Doryctobracon areolatus, Asobara anastrephae, Utetes anastrephae and Opius bellus (Braconidae), Aganaspis pelleranoi (Figitidae) and individuals of the Pteromalidae family. One year after the last release, 44 individuals of the exotic parasitoid were found, showing its establishment in the studied areas.Keywords: Biological control. Diachasmimorpha longicaudata.

Diachasmimorpha longicaudata é um dos mais importantes agentes de controle biológico de moscas-das-frutas em liberações aumentativas. Este trabalho objetivou avaliar a capacidade desse parasitoide em aumentar seu índice de parasitismo de moscas-das-frutas e a pressão que ocasiona em outras espécies nativas de parasitoides. Coletaram-se pitangas, araçás, goiabas, goiabasserranas, caquis, nêsperas, pêssegos e guabirobas em Porto Alegre e Eldorado do Sul, Rio Grande do Sul (RS). No laboratório, os frutos foram divididos em dois lotes iguais e colocados em duas gaiolas. O grupo tratamento foi exposto a D. longicaudata por 24 horas, enquanto o testemunha não. Após o período de exposição, os frutos foram retirados das gaiolas e armazenados até a formação de pupários, que foram mantidos até a emergência de insetos. Anastrepha fraterculus foi o tefritídeo mais abundante. No lote tratamento, obteve-se o maior índice de parasitismo em araçás (68,4%), e o menor, em nêsperas (14,75%). Não se registrou parasitismo em caquis. Identificaram-se os himenópteros nativos: Doryctobracon areolatus (Braconidae), Utetes anastrephae (Braconidae) e Aganaspis pelleranoi (Figitidae), em ambos os lotes. Os resultados indicam que D. longicaudata tem potencial para aumentar os índices de parasitismo no RS sem causar a deleção de espécies nativas.
