Pseudacteon notocaudatus and Pseudacteon obtusitus (Diptera: Phoridae), two new species of fire ant parasitoids from South America.
Ongoing studies in South America of phorid flies of the genus Pseudacteon Coquillett 1907 have revealed two further new species in this genus that are described here: P. obtusitus and P. notocaudatus. Both species are parasitoids of Solenopsis (F.) fire ants.

Environ. Entomo!. 26(5): 1149-1154 (1997) ABSTRACT Pselldacteon phorids that parasitize the red imported fire ant, Solenopsis invicta Buren, inSouthAmericaare not present in the introduced range ofthispest speciesin the United States. Sequential host specificity tests were conducted with 4 South American Pselldacteon species, P. litoralis Borgmeier, P. wasmanni (Schmitz), P. triCllspis Borgmeie...
متن کاملPhenology and Dispersal in Pseudacteon Flies (Diptera: Phoridae), Parasitoids of Solenopsis Fire Ants (Hymenoptera: Formicidae)
The phenology and dispersal abilities of Pseudacteon phorid ßies, parasitoids of Solenopsis Þre ants, were measured at multiple sites over several years. Four Pseudacteon species [P. browni Disney, P. spatulatus (Malloch), P. crawfordi Coquillett, and an undescribed species, P. sp. A.] were found in the vicinity of 5 S. geminata (F.) populations over a 3-yr period. P. browni was the most common...
متن کاملHost Specificity in Two Additional Pseudacteon Spp. (diptera: Phoridae), Parasitoids of Solenopsis Fire Ants (hymenoptera: Formicidae)
We tested the host specificity of two South American Pseudacteon phorid flies, P. obtusus Borgmeier and P. borgmeieri Schmitz, on North American colonies of the red imported fire ant, Solenopsis invicta Buren, and the tropical fire ant, S. geminata (F.). Sequential host specificity tests conducted in the laboratory indicated that P. obtusus was highly specific to S. invicta . In individual tria...
متن کاملMechanisms of Pseudacteon Parasitoid (Diptera: Phoridae) Effects on Exploitative and Interference Competition in Host Solenopsis Ants (Hymenoptera: Formicidae)
I conducted a series of laboratory experiments to quantify the effects and elucidate the mechanisms by which Pseudacteon tricuspis Borgmeier phorid ßies affect the exploitative and interference components of interspeciÞc competition in host Solenopsis invicta Buren ants. In manipulative experiments, workers retrieved 50% less food in a foraging tray with phorids present, compared with an equidi...
