Distribution and Management of the Red Imported Fire Ant, Solenopsis invicta Buren, in Virginia
Red imported fire ant specimens were first collected in Virginia in 1989 from colonies located in Hampton, Va. Now colonies are established throughout the Hampton Roads area of Virginia. Because the fire ant is a new pest information regarding the distribution, biology, and management of the ant in …

Variation and Adaptation in the Imported Fire Ant Solenopsis Saevissima Richteri Forel in the Gulf States
The imported fire ant, Solenopsis saevissima richteri Forel, is the southernmost race of a widespread and highly variable South American ant. It was introduced into the port of Mobile, Alabama, sometime around 1918 and by 1949 had spread to parts of Florida, Mississippi, and Louisiana. 2. A great …

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 …

Pathophysiology and transmission of Thelohania solenopsae in the red imported fire ants, Solenopsis invicta
… pathogens found in the red imported fire ant, Solenopsis invicta. These pathogens cause detrimental effects to their fire ant hosts. The present study revealed that the midgut and the meconium materials from pupating fourth instar larvae were possible vehicles for the horizontal …

Population ecology of Pseudacteon tricuspis Borgmeier (Diptera: Phoridae), an introduced parasitoid of the red imported fire ant Solenopsis invicta Buren (Hymenoptera: formicidae) in Louisiana
… (Pseudacteon 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
… another invasive 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 …

Functional Studies of Novel Bioactives From Complex Host-Microbiomes as Drug Leads for Cancer, Infectious Disease, Depression and Pain
… to some extent with the emergence of recombinant technologies and new synthetic methodology. With approximately 60 years of research performed after the development of SCUBA, the drug discovery opportunities in the sea are still too numerous to count. Since the FDA approval of the …

The consequences and implications of ecology on body size distributions in social insects
… Additionally, in approximately 13% of ant species worker variation is large enough that the worker caste can be subdivided into sub-castes based on size and shape. For these polymorphic species, body size is both an individual and a colony-level trait (distribution of worker body …

Effects of fragmentation and invasion on ant communities
… uses such as pastures, sugarcane and oil palm plantations. The resulting remnants generally maintain lower species diversity relative to unfragmented forest, and the species composition of what remains often includes generalist and invasive species. Another causative agent of extinction are …
