Purification of the Fire Ant Trail Substance

  title={Purification of the Fire Ant Trail Substance},
  author={CHRISTOPHER T. Walsh and John H. Law and Edward O. Wilson},
THE fire ant, Solenopsis saevissima (Fr. Smith), utilizes a trail substance as an aid in effective foraging1. Workers secrete a substance from the Dufour's gland which is deposited from the sting in the form of minute streaks. These mark a trail from a suitable food source to the nest. Workers are strongly attracted to this substance and follow the trail outward to the food source. The newly recruited workers in turn lay trails to the nest, reinforcing the original trail. The appropriate… 
Isolation of the trail recruitment pheromone ofSolenopsis invicta
This is the first report that demonstrates that different exocrine products from the same gland control different subcategories of behavior related to mass recruitment.
Hydrocarbons on Harvester Ant (Pogonomyrmex barbatus) Middens Guide Foragers to the Nest
It is shown that hydrocarbons found on the mound of Pogonomyrmex barbatus nests facilitate the return of foragers to the nest, and the chemical environment of the nest mound contributes to the regulation of foraging behavior in harvester ants.
Biology and control of imported fire ants.
The purpose here is to review this research, although because of space limitations, much of the recent work concerning the chemical toxicology and persistence of mirex, the chemical currently used for control of imported fire ants.

Summary1.The trail substance of Lasius fuliginosus is neither colony nor caste specific. All tested species of the subfamily Formicinae accumulate their trail substance in the rectal ampulla. The
Dufour glands in the hymenopterans (Apidae, Formicidae, Vespidae): a review.
Its original function of egg-protective substance producing, or favoring the oviposition, appear to have been replaced or complemented in hymenopterans by the production of semiochemicals with function in communication.
Mercury Detoxification and Natural Product Synthesis: the Work of Christopher T. Walsh
Christopher Thomas Walsh elucidation of the process by which bacteria detoxify mercury-containing molecules in the environment by cleaving carbon-mercury bonds and then reducing the mercuric salt to elemental mercury and is widely recognized for spurring a renaissance in natural product biosynthesis.


Source and Possible Nature of the Odor Trail of Fire Ants
Experimental evidence shows that the odor trail of the fire ant Solenopsis saevissima (Fr. Smith) is produced as a secretion of the accessory gland of the poison apparatus and released through the
