Sampling and dynamics of Pseudacteon tricuspis (Diptera: Phoridae) in Louisiana.
The population dynamics of a fire ant (Solenopsis invicta Buren) parasitoid (Pseudacteon tricuspis Borgmeier) was studied in Louisiana. The objectives of this study were to understand the daily and seasonal population dynamics of P. tricuspis in the context of environmental variables, determine whether P. tricuspis populations were synchronized over local and regional scales, determine the sex ...
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 کاملPseudacteon 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.
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...
متن کاملPatterns of Host Specificity in Pseudacteon Parasitoid Flies (Diptera: Phoridae) that Attack Solenopsis Fire Ants (Hymenoptera: Formicidae)
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...
