Fire ant-detecting canines: a complementary method in detecting red imported fire ants.
In this investigation, detection dogs are trained and used in identifying red imported fire ants, Solenopsis invicta Buren, and their nests. The methodology could assist in reducing the frequency and scope of chemical treatments for red imported fire ant management and thus reduce labor costs and chemical use as well as improve control and quarantine efficiency. Three dogs previously trained fo...
متن کاملSpecificity of the Red Imported Fire Ant Phagostimulant Response to Carbohydrates
The red imported fire ant, Solenopsis invicta Buren, is considered an oil-loving feeder, however, carbohydrates are essential ingredients in the diet of the fire ant also. Comprehensive screening of mono-, di-, and tri-saccharides demonstrated that glucose, fructose, fucose, sucrose, maltose, turanose and raffinose were significant phagostimulants for fire ant workers. It was also found that wh...
متن کاملRepellency of callicarpenal and intermedeol against workers of imported fire ants (Hymenoptera: Formicidae).
Callicarpenal and intermedeol are two insect-repellent terpenoids isolated from leaves of American beautyberry (Callicarpa americana L.; Verbenaceae) and Japanese beautyberry (Callicarpa japonica Thunb.). The repellency of these two terpenoids against workers of red imported fire ants, Solenopsis invicta Buren, black imported fire ants, Solenopsis richteri Forel, and a hybrid of these two speci...
متن کاملDiscovering Pheromones of the Red Imported Fire Ant (Solenopsis invicta Buren): A Review and Proposed New Target for Pheromone Disruption1
A method is described for discovering pheromones of the red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), using affinity chromatography with the pheromone-binding proteins of the ant. Proteins in the pheromoneand odorant-binding protein family, which are abundant in moths and other insect species, are not apparent in fire ant antennae. Two other types of hydrophobic lig...
متن کاملUse of Chemical Characters in Defining Populations of Fire Ants
The fire ants, Solenopsis invicta and S. richteri, were accidentally imported into the United States in the first half of this century from South America. In their adopted habitat the imported fire ants have thrived causing considerable medical and agricultural problems in the nine widely infested states of the south and southeast. The red imported fire ant, S. invicta was considered the domina...
