Behavioral and biochemical evidence is presented for hybridization between the fire ants,Solenopsis richteri andS. invicta. The response of the two species to extracts of their trail pheromones presented as a point source is clearly species-specific; however, hybrid workers responded to parental Dufour's gland extracts and parental workers responded to Dufour's gland extracts of the hybrid. The behavioral evidence for hybridization was confirmed by gas Chromatograph comparison of the Dufour's… Expand

The Trail Pheromone of the Venomous Samsum Ant, Pachycondyla sennaarensis
TLDR
It was demonstrated that workers of the venomous samsum ant, Pachycondyla sennaarensis (Mayr), employ recruitment trail pheromones discharged from the Dufour's gland, which demonstrates effective longevity for about one hour. Expand
Hybridization in the European carpenter ants Camponotus herculeanus and C. ligniperda (Hymenoptera: Formicidae)
TLDR
The presented case increases the known ratio of hybridizing species within the 178 ant species of Central Europe to 19.1%. Expand
Comparing electroantennogram and behavioral responses of two Pseudacteon phorid fly species to body extracts of Black, Red and Hybrid imported fire ants, Solenopsis spp.
TLDR
The results of the EAG and behavior studies suggest that parasitic phorid flies utilize host derived non-polar compounds from worker ants extracted out by hexane for host location but not for host preference, since both fly species are not able to distinguish among the body extracts of the three fire ant species. Expand
Chemical blueprints to identifying fire ants: overview on venom alkaloids
TLDR
A set of chemical tools to facilitate species diagnosis from field-collected fire ant samples are introduced, herein focusing on minor workers, to help researchers working on fire ants in future studies. Expand
Chemical blueprints to identifying fire ants: overview on venom alkaloids
TLDR
A set of chemical tools to facilitate species diagnosis from field-collected fire ant samples are introduced, herein focusing on minor workers, to help researchers working on fire ants in future studies. Expand
Host preference in Pseudacteon phorid flies: response of P. tricuspis and P. curvatus to black, red and hybrid imported Solenopsis fire ants in multiple choice bioassays
TLDR
The results suggest that both biotypes may have evolved a specialized relationship with red IFA including an ability to discriminate it from related fire ants. Expand
Statewide survey of imported fire ant (Hymenoptera: Formicidae) populations in Tennessee.
TLDR
The survey results are being used to direct current and future biological control efforts against imported fire ants in Tennessee and the first detection of polygyne imported fire ant in Tennessee was detected. Expand
Phylogeography of two European Reticulitermes (Isoptera) species: the Iberian refugium
TLDR
The phylogeography of Reticulitermes termites collected from various parts of France, Spain and Portugal revealed intraspecific differentiation into two major lineages with distinct geographical ranges, and phylogeny based on the analysis of mitochondrial DNA showed its close kinship with the R. grassei lineage occurring in southern Spain. Expand
A Comparative Study between Solenopsis invicta and Solenopsis richteri on Tolerance to Heat and Desiccation Stresses
TLDR
Testing the hypothesis that S. invicta is more tolerant to heat and desiccation stress than S. richteri found the data strongly support this hypothesis and indicates that cuticular lipids were not the only factors accounting for difference in theDesiccation resistance between these two species. Expand
Quantitative analysis of alkaloidal constituents in imported fire ants by gas chromatography.
TLDR
A method based on silica gel chromatography and GC-MS/GC-FID analyses was developed for the quantitation of alkaloidal compounds in imported fire ants, Solenopsis richteri, S. invicta, and their hybrid found in the southern United States and the results were discussed in relation to the evolution of fire ant venom alkaloids and their role as host location cues for parasitic Pseudacteon phorid flies.

Symposium: New Technologies for the Taxonomic Identification of Arthropods: Use of Chemical Characters in Defining Populations of Fire Ants, Solenopsis Saevissima Complex, (Hymenoptera: Formicidae)
TLDR
The use of three species-specific chemical characters (venom alkaloids, cuticular hydrocarbons, and trail pheromones) to define S. invicta, S. richteri, and hybrid populations in the United States have important consequences regarding the species status of the two imported fire ants and the taxonomy of fire ant populations in South America.

Orientation and recruitment behavior in the ponerine ant Pachycondyla tesserinoda (Emery): laying of individual-specific trails during tandem running
TLDR
Tandem leaders of Pachycondyla tesserinoda mark their way during nest moving with colony-specific trails while scouting and foraging for food in an unknown area, chemical orientation is used as well. Expand
Hydrocarbon components of the trail pheromone of the red imported fire ant, Solenopsis Invicta
Abstract Terpenoid trail pheromone components were isolated from whole worker extracts of the red imported fire ant, and identified as Z,E and E,E -α-farnesene, and the previously unreported… Expand
Fire ant trail pheromones: Analysis of species specificity after gas chromatographic fractionation
TLDR
The specificity of the trail pheromones of four Solenopsis species was determined using natural trails, and purified fractions from Dufour's gland extracts collected after gas-chromatographic separation, to find that S. richteri and S. invicta possess species-specific major trail phersomones.

Chemical communication among workers of the fire ant Solenopsis saevissima (Fr. Smith) 1. The Organization of Mass-Foraging
TLDR
Recruitment in mass foraging is organized almost exclusively by the use of the trail substance, which is secreted by Dufpur's gland and released through the extruded sting, a powerful attractant which excites workers and draws them out of the nest in the direction indicated by the trail. Expand
