Title A name given to the resource Efeito da estrutura de habitat sobre a abundância de parasitóides Pseudacteon Coquillett (Diptera, Phoridae) em ninhos de Solenopsis invicta Buren (Hymenoptera, Formicidae) Influence of habitat structure on the abundance of the parasitoids Pseudacteon Coquillett (Diptera, Phoridae) on mounds of Solenopsis invicta Buren (Hymenoptera, Formicidae) Creator An entity primarily responsible for making the resource Fábio Souto Almeida, Jarbas Marçal Queiroz Description An account of the resource A influência de características do habitat na abundância dos parasitóides Pseudacteon Coquillett (Diptera, Phoridae) de Solenopsis invicta Buren (Hymenoptera, Formicidae) foi estudada em um agroecossistema orgânico diversificado no sudeste do Brasil. Os parasitóides foram coletados durante 30 minutos após a perturbação de ninhos da formiga lava-pé em áreas com culturas anuais ou perenes. Foram coletados no total 228 parasitóides de quatro espécies diferentes em 61,90% dos 84 ninhos da formiga lava-pé perturbados. Pseudacteon obtusus Borgmeier foi a espécie mais abundante (70 fêmeas), seguida por Pseudacteon litoralis Borgmeier (37 fêmeas), Pseudacteon tricuspis Borgmeier (23 fêmeas) e Pseudacteon solenopsidis Schmitz (1 fêmea). Pseudacteon litoralis foi mais freqüente em ninhos presentes nas culturas perenes que anuais enquanto que P. obtusus e P. tricuspis tiveram um padrão oposto. Correlações significativamente negativas foram encontradas para as abundâncias de P. litoralis e P. obtusus com a temperatura do ar. Houve correlação significativamente positiva entre a abundância dos parasitóides e o tamanho dos ninhos da formiga lava-pé. Considerando que os forídeos são importantes inimigos naturais de S. invicta, esse estudo fornece informações para o manejo de S. invicta em agroecossistemas tropicais diversificados.The influence of habitat characteristics on the abundance of the parasitoids Pseudacteon Coquillett (Diptera, Phoridae) of Solenopsis invicta Buren (Hymenoptera, Formicidae) was studied in organic polyculture agroecosystem in southeastern of Brazil. Parasitoids were collected during 30 minutes after fire ant colonies perturbation in plots with annual or perennial crops. A total of 228 parasitoids belonging to four species were obtained in 61.90% of the 84 fire ant colonies disturbed. Pseudacteon obtusus Borgmeier was the most abundant species (70 females), followed by Pseudacteon litoralis Borgmeier (37 females), Pseudacteon tricuspis Borgmeier (23 females) and Pseudacteon solenopsidis Schmitz (1 female). Pseudacteon litoralis was more frequent on fire ant mounds in plots with perennial crops than annual crops whereas P. obtusus and P. tricuspis had an opposed pattern. Negative significant correlation was found between air temperature and P. litoralis and P. obtusus abundances. Fire ant mound size and parasitoid abundance were positively correlated. Considering that phorids are important natural enemies of S. invicta, this study provides information for the management of fire ants in tropical polyculture agroecosystem.
