1. Geographical transition zone of Solenopsis fire ants (Hymenoptera: Formicidae) and Pseudacteon fly parasitoids (Diptera: Phoridae) in the state of São Paulo, Brazil
Solenopsis saevissima (Smith) and Solenopsis invicta Buren are the most abundant and widely distributed fire ants in Brazil. The occurrence of the two fire ant species and of their parasitoids Pseudacteon spp. is described for a climatic and phytophysiognomic transition area in the state of São Paulo. Both fire ant species have a parapatric distribution, ap

2. Cytogenetic analysis of three species of Pseudacteon (Diptera, Phoridae) parasitoids of the fire ants using standard and molecular techniques
Pseudacteon flies, parasitoids of worker ants, are being intensively studied as potentially effective agents in the biological control of the invasive pest fire ant genus Solenopsis (Hymenoptera: Formicidae). This is the first attempt to describe the karyotype of P. curvatus Borgmeier, P. nocens Borgmeier and P. tricuspis Borgmeier. The three species possess

3. Efeito da estrutura de habitat sobre a abundância de parasitóides Pseudacteon Coquillett (Diptera, Phoridae) em ninhos de Solenopsis invicta Buren (Hymenoptera, Formicidae)
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

4. Ecologia de Solenopsis invicta Buren (Hymenoptera: Formicidae) em um agroecossistema diversificado sob manejo orgânico. / Ecology of Solenopsis invicta Buren (Hymenoptera: Formicidae) in an agroecosystem.
Solenopsis invicta Buren (Hymenoptera: Formicidae) (formiga-lava-pé), espécie nativa da América do Sul, hoje ocorre na América Central, América do Norte e Oceania. A espécie é considerada uma praga importante devido às altas densidades populacionais, agressividade e à sua picada desagradável, podendo provocar reações alérgicas. A espécie pode t

5. Populational and taxonomical studies of fire ants, Solenopsis invicta (Hymenoptera: Formicidae), and of the phenology of their parasitoids of the genus Psedacteon (Diptera: Phoridae) / Estudos populacionais e taxonomicos de formigas lava-pes, Solenopsis invicta (Hymenoptera: Formicidae) e da fenologia de seus parasitoides do genero Pseudacteon (Diptera: Phoridae)
This work discusses some aspects of the ecology of the fire ant species Solenopsis invicta and its phorid parasitoid flies ofthe genus Pseudacteon, and ofthe taxonomy of S. invicta and S. saevissima, both of which are native to South America. The allometry of S. invicta colonies in southeast Brazil was studied by measurement of mound (aboveground) dimensions

6. Ecologia da interação entre formigas invasoras e moscas parasitoides
The establishment of exotic species is an important disturbing factor of native community. The knowledge of the ecology of these invading species in their native range is fundamental to handle effectively the problem. The red fire ant, Solenopsis invicta Buren, and the Argentine ant, Linepithema humile (Mayr), are invading species in many places, bringing ec
