Distribution and Management of the Red Imported Fire Ant, Solenopsis invicta Buren, in Virginia
… spp. parasitoid decapitating phorid flies, and Solenopsis invicta virues (SINV) genetic materials were detected in fire ant samples. CLIMEX model results indicate that fire ants will be able to spread as far east as the Greater Richmond area and as far north as Alexandria in Virginia.

Biological Control of Red Imported Fire Ant (Solenopsis invicta) Using Pseudacteon (Diptera: Phoridae) in Central Arkansas
<p>Red imported fire ants are major pests in the southeastern United States. As a part of an integrated pest management strategy, a biological control program has been implemented which includes Pseudacteon decapitating flies. These flies are parasitoids of fire ant workers and two species of …

Culture-independent identification of gut bacteria in fourth-instar red imported fire ant, Solenopsis invicta Buren, larvae
Red imported fire ants (RIFA), Solenopsis invicta Buren, are medical, urban, and agricultural pests from South America. Fourth-instar larvae are used by the colony to digest solid food and then regurgitate it for consumption by workers and queens. Larvae are an ideal source of investigations of …

The red imported fire ant, Solenopsis invicta, in early-successional coastal plain forests: tests of distribution and interaction strength
The red imported fire ant, Solenopsis invicta, is an abundant and aggressive component of early-successional communities in the southeastern United States. After disturbance, it rapidly invades new habitats, and once there, it has strong competitive and predatory effects on the existing arthropod …

Spread of Red Imported Fire Ant, Solenopsis invicta, in Virginia and effects of sub-lethal exposure to agrochemicals on its behavior
Solenopsis invicta is an invasive ant that has caused detrimental impacts to ecosystems and economies in the Southeastern United States, recently including Virginia. In this study, we explored the invasion ecology of S. invicta through two main objectives. First, we established a comprehensive …

Predation on lizard eggs by ants: interaction modifications in an unstable physical environment
… in the rate of predation on lizard eggs by Solenopsis ants induced by annual variation in wet season rainfall. I tested this hypothesis by manipulating water availability on experimental plots to Simulate the wettest (HW) and driest (LW) wet seasons in the last twenty years. The mean time to …

Population ecology of Pseudacteon tricuspis Borgmeier (Diptera: Phoridae), an introduced parasitoid of the red imported fire ant Solenopsis invicta Buren (Hymenoptera: formicidae) in Louisiana
… tricuspis) of the red imported fire ant (Solenopsis invicta) in Louisiana were studied. The spatio-temporal abundance patterns, dispersal, population spread, aggregation, direct mutual interference and functional response characteristics of this parasitoid were studied to address …

A Comparison of the Viability of Thistle Weevils From Fire Ant Suppressed Site to Weevils From a Site Where Fire Ants Were Not Suppressed
… non-native, the red imported fire ant, <em>Solenopsis invicta</em>. The research compared the viability of <em>R. conicus</em> from a <em>S. invicta</em> suppressed site to the viability from a non suppressed site. Although the evidence suggests there is a difference in viability where fire …

Survival, Movement, and Fine-Scale Habitat Selection of Reintroduced Texas Horned Lizards (Phrynosoma cornutum)
… Possible threats include Red Imported Fire Ants (Solenopsis invicta), herbicides and pesticides, habitat destruction and disturbance, and collection for the pet trade. Greater conservation effort is needed for Texas Horned Lizards, requiring more detailed knowledge of their habitat requirements. …
