Florida has become a worldwide hotspot for introduced and invasive ants (Hymenoptera: Formicidae). Furthermore, studies have shown that non-native ants support other invasive insects in Florida, such as the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), which is the vector of Candidatus Liberibacter asiaticus, the causal pat...
The well‐being of Pacific island communities and the ecosystems that support them is inextricably linked. Island ecosystems are fragile, complex, and have often evolved in isolation. Many species have not evolved defenses against common predators such as rats, cats, and invasive ants, and the introduction of new invasive species threatens the delic...

Pseudacteon flies (Diptera: Phoridae) parasitize individual ant workers, causing decapitation of the host during pupariation. Phorid flies that attack South American fire ants in the Solenopsis saevissima (Smith) complex are distributed across a wide range of habitats and climates associated with the geographical range of their hosts. Sympatric spe...
Field evaluations assessing the prevalence of Solenopsis invicta virus 3 (SINV-3) have shown that the virus exhibits a distinct seasonal phenology in the host, Solenopsis invicta, that is negatively correlated with warmer temperatures. Active SINV-3 infections were established in Solenopsis invicta colonies, which were subsequently maintained at 19...
The red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), is a stinging, invasive ant from South America that has plagued the southern US since the 1930s. It is currently established in parts of California, including the Coachella Valley. We introduced and established the fire ant decapitating phorid flies, Pseudacteon curvatus...
The small decapitating fly, Pseudacteon bifidus Brown and Morrison (Diptera: Phoridae), is a parasitoid of the tropical fire ant, Solenopsis geminata (F.) (Hymenoptera: Formicidae). This fly is of interest as a potential self-sustaining biocontrol agent because tropical fire ants are invasive pests throughout the world's tropics, especially on isla...
The tropical fire ant, Solenopsis geminata (F.) (Hymenoptera: Formicidae), is an invasive pest throughout most of the tropics, especially on islands in the Pacific. Natural enemies such as the fire ant decapitating fly, Pseudacteon bifidus Brown and Morrison (Diptera: Phoridae), offer the potential for use as self-sustaining biological control agen...
