Trail Communication in the Dacetine Ant Orectogna Thus Versicolor (Hymenoptera: Formicidae)

Trail Pheromone of the Argentine Ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae)

The Argentine ant (Linepithema humile) is recognized as one of the world's most damaging invasive species. One reason for the ecological dominance of introduced Argentine ant populations is their ability to dominate food and habitat resources through the rapid mobilization and recruitment of thousands of workers. More than 30 years ago, studies showed that (Z)-9-hexadecenal strongly attracted A...

A North Florida Ant Fauna (Hymenoptera: Formicidae)

Argentine ant (Hymenoptera: Formicidae) trail pheromone enhances consumption of liquid sucrose solution.

We investigated whether the Argentine ant, Linepithema humile (Mayr), trail pheromone, Z9-16:Ald, could enhance recruitment to and consumption of liquid sucrose solutions. All tests were done as paired comparisons with a 10% sucrose solution as food. In the laboratory, mixing 20 microl of a 10-microg/ml solution of the pheromone with 50 microl of the 10% sucrose solution increased the number of...

Foraging behavior in the ant genus Messor (Hymenoptera: Formicidae: Myrmicinae)

The genus Messor consists of 113 species of seed harvesting ants that are found in grasslands, semi-arid areas and savannahs in both the Old and New World. A full spectrum of foraging strategies occurs in Messor, ranging from individual to group foraging, with the latter having evolved several times. This paper reviews foraging strategies and the underlying behavioral mechanisms found in specie...

Ant (Hymenoptera: Formicidae) Communities of the Southern Cumberland Plateau

The Cumberland Plateau supports diverse plant communities that vary greatly across cove and plateau habitats. Unfortunately, little is known about how terrestrial invertebrate communities vary across cove andplateauhabitats andhowdisturbanceaffects these communities. Toaddress this deÞciency, we used the Ant Leaf Litter protocol to survey ant diversity on the southern Cumberland Plateau in Tenn...
