Abstract We studied the developmental performance of the large biotype of Pseudacteon obtusus Borgmeier, a promising biological control agent of imported fire ants. We measured selected life history traits of this parasitoid as a function of (1) host species (Solenopsis invicta Buren versus Solenopsis richteri Forel), (2) temperature (22 versus 28°C), and (3) size distributions of available host ants (big versus mixed-size classes of workers). Survivorship on S. invicta was much greater than… 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
TLDR
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
A Small Parasitoid of Fire Ants, Pseudacteon obtusitus (Diptera: Phoridae): Native Range Ecology and Laboratory Rearing
TLDR
Pseudacteon obtusitus has 2 seasons of peak abundance, and exhibits low tolerance for cold temperatures or extended cold periods, and holds interest for inclusion among the multi-species assemblage of parasitoid flies considered for biological control of S. invicta in its invasive range in North America. Expand
Rearing and Biology of the Decapitating Fly Pseudacteon bifidus (Diptera: Phoridae): A Parasitoid of Tropical Fire Ants
TLDR
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
Introduction of the fire ant decapitating fly Pseudacteon obtusus in the United States: factors influencing establishment in Texas
The introduction and establishment of Pseudacteon obtusus Borgmeier (Diptera: Phoridae) into the United States is an important milestone in the effort to introduce a suite of parasitoids andExpand
Laboratory Rearing and Niche Resources of Pseudacteon spp. Coquillett (Diptera: Phoridae) Parasitoids of Solenopsis saevissima (Smith) (Hymenoptera: Formicidae)
TLDR
The daily period of activity and body size are important factors to be considered in the use of these natural enemies in future programs of biological control of S. saevissima. Expand
Optimal Conditions to Rear Phorid Parasitoids (Diptera: Phoridae) of Atta vollenweideri and Acromyrmex lundii (Hymenoptera: Formicidae)
TLDR
This temperature and humidity combination is suggested as the most suitable for rearing these species, whereas the 20HH treatment is ideal for maintaining adults for longer periods, which would be advantageous for synchronizing matings and mass releases of adults in the field. Expand
BIoNomIcS 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 parasitoidsExpand
Biological attributes of Argentinian phorid parasitoids (Insecta: Diptera: Phoridae) of leaf-cutting ants, Acromyrmex and Atta
TLDR
The results helped to increase the knowledge of the phorids of leaf-cutters, and highlighted their potential use for the biocontrol of these ants. Expand
Geographical transition zone of Solenopsis fire ants (Hymenoptera: Formicidae) and Pseudacteon fly parasitoids (Diptera: Phoridae) in the state of São Paulo, Brazil.
TLDR
Both fire ant species have a parapatric distribution, apparently determined by the climate: S. saevissima predominates in the north part of São Paulo (Aw climate), while S. invicta in the south (Cfa climate). Expand

Development of Pseudacteon cultellatus (Diptera: Phoridae) on Solenopsis invicta and Solenopsis richteri Fire Ants (Hymenoptera: Formicidae)
TLDR
Although larval developmental times did not differ as a function of sizes of host offered, average time of development in the pupal stage was extended by 12% in the case of host size mixtures which included workers larger than the phorid’s preferred host size in comparison to homogeneously small ants.

Immature Development of Pseudacteon tricuspis (Diptera: Phoridae), an Endoparasitoid of the Red Imported Fire Ant (Hymenoptera: Formicidae)
TLDR
The parasitization and development of P. tricuspis in two sizes of ants is described and the behavioral response of these ants to the attack of this fly is evaluated. Expand
Developmental Rates and Host Specificity for Pseudacteon parasitoids (Diptera: Phoridae) of Fire Ants (Hymenoptera: Formicidae) in Argentina
TLDR
The concept of incorporating several complementary species of Pseudacteon in the biological control of pest fire ants is supported, with development times for seven Argentinean parasitoid species reared on two hosts under laboratory temperature regimes comparable with those of the climatic zones occupied by these host species.

Pseudacteon Obtusus (Diptera: Phoridae) Attacking Solenopsis Invicta (Hymenoptera: Formicidae) in Brazil
TLDR
Field observations of Pseudacteon attack on foraging S. invicta workers and document parasite oviposition on a host ant indicate that the parasite preferentially attacks major workers of the host species. Expand

TLDR
The phenology and dispersal abilities of Pseudacteon phorid flies, parasitoids of Solenopsis fire ants, were measured at multiple sites over several years, and overall sex ratios were always highly male-biased at all sites and in all years, with 1 exception. Expand

Host Specificity of Fire Ant Decapitating Flies (Diptera: Phoridae) in Laboratory Oviposition Tests
TLDR
Host specificities of 3 species of Pseudacteon decapitating flies were tested in quarantine facilities in Gainesville, FL, indicating that the field release of P. tricuspis poses some risk to native fire ants; however, the extremely low rates of attack on S. geminata in the laboratory and in the field indicate that this risk would be minimal.
