| developmental rates and host specificity for pseudacteon parasitoids (diptera: phoridae) of fire ants (hymenoptera: formicidae) in argentina. | this study extends our comparative knowledge of pseudacteon interactions with solenopsis fire ant workers. reported in this work are development times for seven argentinean parasitoid species reared on two hosts, solenopsis richteri forel and solenopsis invicta buren, under laboratory temperature regimes comparable with those of the climatic zones occupied by these host species. developmental times spanned 31-66 d across phorid species, and in general did not differ between genders or host speci ... | 2002 | 12539825 |

| 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. | we assessed the performance of pseudacteon curvatus borgmeier with respect to the social form of solenopsis invicta buren in argentina in the field, we studied the effect the parasitoid on size and proportion of ant foragers. in the laboratory, we evaluated p. curvatus oviposition preferences; host size elected; developmental periods; and sexual size dimorphism, sex ratio, and parasitoid survivorship. p. curvatus affected the average size of foraging workers on both social forms diminishing the ... | 2009 | 19791615 |
| fire ant alarm pheromone and venom alkaloids act in concert to attract parasitic phorid flies, pseudacteon spp. | pseudacteon tricuspis, pseudacteon obtusus and pseudacteon curvatus are three species of parasitic phorid flies (diptera: phoridae), which have been introduced as classical biological control agents of imported, solenopsis fire ants (hymenoptera: formicidae) in the southern usa. previous studies demonstrated the behavioral response of p. tricuspis to the venom alkaloids and alarm pheromone of the fire ant, s. invicta. in the present study, we compared the responses of p. tricuspis, p. obtusus an ... | 2013 | 24035750 |
| comparing electroantennogram and behavioral responses of two pseudacteon phorid fly species to body extracts of black, red and hybrid imported fire ants, solenopsis spp. | several phorid fly species were introduced to the southern united states for biological control of the invasive imported fire ants, solenopsis richteri (black), solenopsis invicta (red), and their hybrid s. richteri×s. invicta (hybrid). it has been previously reported that the jaguariuna biotype of pseudacteon tricuspis and the formosan biotype of pseudacteon curvatus could distinguish among the three fire ant species with greater preference for hybrid and red fire ants. we hypothesized that pho ... | 2012 | 22846844 |
