ABSTRACT We studied how the behavior and performance of Pseudacteon tricuspis Borgmeier varies with the social form of its host Solenopsis invicta Buren, in its native range in Argentina where monogyne colonies are more abundant than polygynes (≈75 vs. 25%). Female, P. tricuspis took 44% less time (50 vs. 89 s) to attack monogyne than polygyne ants, but oviposition attempts were similar (23 vs. 18 attacks). The presence of the parasitoid affected the average size of foragers on the trail… Expand
Rearing and Biology of the Decapitating Fly Pseudacteon bifidus (Diptera: Phoridae): A Parasitoid of Tropical Fire Ants
Methods for mass rearing P. bifidus were developed by modifying preexisting rearing procedures to provide adults access to water and sugar water so they could live longer, by extending access to hosts for 1 to 2 extra d, and by avoiding reuse of host colonies with poor rates of parasitism. Expand
Parasitism, sexual dimorphism and effect of host size on Apocephalus attophilus offspring, a parasitoid of the leaf-cutting ant Atta bisphaerica
Evaluated which parasitoid species attack the leaf-cutting ant A. bisphaerica in pasture areas of a Brazilian Savannah-Atlantic Forest ecotone, parasitism rate, effect of host size, sexual dimorphism and sex ratio of the emerged parasitoids showed Apocephalus attophilus would be a potential biocontrol agent of leaf- cutting ants.

Effect of phorid fly density on the foraging of Atta vollenweideri leafcutter ants in the field
The results show that releases of these phorids into the field should not necessarily involve many individuals to reduce foraging by A. vollenweideri, making them potentially useful candidates for biological control of these ants. Expand
Pseudacteon Phorid Flies: Host Specificity and Impacts on Solenopsis Fire Ants.
This review focuses on the mechanisms underlying host location, host preference, and host-size selection of Pseudacteon phorid flies and highlights their direct and indirect effects on fire ant populations. Expand
Importation biological control of invasive fire ants with parasitoid phorid flies—progress and prospects
Information gained from the successful importation and establishment of South American phorid flies in the US can provide guidance for utilization of these parasitoid flies for biological control of S. invicta in other introduced ranges, and aid the search for additional importation biological control agents of pest ants in general.

Biology of Pseudacteon Decapitating Flies (Diptera: Phoridae) That Parasitize Ants of the Solenopsis saevissima Complex (Hymenoptera: Formicidae) in South America
Pseudacteon flies (Diptera: Phoridae) parasitize individual ant workers, causing decapitation of the host during pupariation, with the potential of being used for biological control of the imported fire ants in North America, Australia, and Asia. Expand
Mitigating the allergic effects of fire ant envenomation with biologically based population reduction
Specific, self-sustaining biological control agents have been discovered, studied, and released into fire ant populations in the United States in an effort to re-establish an ecological/competitive balance, resulting in reduced fire ant densities and human exposure. Expand


Behavior and Development of Pseudacteon curvatus (Diptera: Phoridae) Varies According to the Social Form of Its Host Solenopsis invicta (Hymenoptera: Formicidae) in Its Native Range
The rarity of polygyne S. invicta in its native range may prevent this phorid from adjusting its life history to that social form, and consequences of applying thisphorid in biological control are discussed. Expand
Oviposition behavior and development of Pseudacteon flies (Diptera: Phoridae), parasitoids of Solenopsis fire ants (Hymenoptera: Formicidae).
We studied the oviposition behavior and larval development of Pseudacteon phorid flies, which are parasitoids of Solenopsis fire ants. Four South American Pseudacteon spp., P. litoralis Borgmeier, P.Expand
Post-Release Host-Specificity Testing of Pseudacteon tricuspis, a Phorid Parasitoid of Solenopsis Invicta Fire Ants
Tests of host specificity on introduced populations of Pseudacteon tricuspis found it to be highly host specific and pose no obvious threat to nontarget species. Expand
Host Specificity of a Biotype of the Fire Ant Decapitating Fly Pseudacteon curvatus (Diptera: Phoridae) from Northern Argentina
It is demonstrated that this new biotype of P. curvatus is more host specific to North American red imported fire ants than a previous biotype collected from black importedFire ants. Expand
Distribution of the Two Social Forms of the Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in the Native South American Range
It is found that polygyny occurs in a mosaic pattern with respect to the more common monogyne (single queen) social form in the fire ant Solenopsis invicta Buren, a pattern superficially similar to that seen in the introduced range in the United States. Expand
Phenology and parasitism rates in introduced populations of Pseudacteon tricuspis, a parasitoid of Solenopsis invicta
We documented patterns of seasonal abundance and rates of parasitism in introduced populations of Pseudacteon tricuspis Borgmeier, a phorid parasitoid of the red imported fire ant, Solenopsis invictaExpand
Evaluating biological control of fire ants using phorid flies: effects on competitive interactions
In light of a literature search indicating that laboratory tests of biological control agent efficacy are good predictors of field efficacy, it is concluded that P. tricuspis alone is unlikely to suppress S. invicta populations in the field by reducing their competitive ability. Expand
Sex ratio variation as a function of host size in Pseudacteon flies (Diptera: Phoridae), parasitoids of Solenopsis fire ants (Hymenoptera: Formicidae)
Examination of Pseudacteon life history reveals several traits assumed to be important in models predicting conditions under which environmental sex determination is favoured, and the pattern of sex ratio variation observed has important implications for biocontrol efforts of imported Solenopsis fire ants by the introduction of PseUDacteon parasitoids.

Comparison of nestmate recognition between monogyne and polygyne populations of Solenopsis invicta (Hymenoptera: Formicidae).
Polygyne workers are less able to distinguish nestmates from nonnestmates than monogyne workers, which fits a theoretical prediction of diminished intraspecific aggression in polygyne populations. Expand
Testing for population-level impacts of introduced Pseudacteon tricuspis flies, phorid parasitoids of Solenopsis invicta fire ants
A multi-year, large-scale field experiment to investigate potential population-level impacts on host Solenopsis invicta Buren fire ants and associated arthropods found P. tricuspis parasitism pressure (averaged over the course of the experiment) was positively associated with changes in S. Invicta density. Expand
