Synthetic Analogs of the Trail Pheromone of the Leaf-Cutting Ant, A tta
nvestigations of the town ant, Atra texnnu (Buckley), revealed the structures of its alarm pheromones (Moser et ul., 1968) and one of its trail-following pheromones (Tumlinson el n/., 1971 ; Wood er a/., 1970). This ant is a pest of pine plantations and farm crops (Moser, 1962); hence chemicals which control its social behavior are of great concern. We have prepared a number of analogs of the t...
متن کاملSynergy between social and private information increases foraging efficiency in ants.
Insect societies integrate many information sources to organize collective activities such as foraging. Many ants use trail pheromones to guide foragers to food sources, but foragers can also use memories to find familiar locations of stable food sources. Route memories are often more accurate than trail pheromones in guiding ants, and are often followed in preference to trail pheromones when t...
متن کاملAnt foraging on complex trails: route learning and the role of trail pheromones in Lasius niger.
Ants are central place foragers and use multiple information sources to navigate between the nest and feeding sites. Individual ants rapidly learn a route, and often prioritize memory over pheromone trails when tested on a simple trail with a single bifurcation. However, in nature, ants often forage at locations that are reached via more complex routes with multiple trail bifurcations. Such rou...
متن کاملConcise syntheses of insect pheromones using Z-selective cross metathesis.
Very short synthetic routes to nine cis-olefin-containing pheromones containing a variety of functionality, including an unconjugated (E,Z) diene, are reported. These lepidopteran pheromones are used extensively for pest control, and were easily prepared using ruthenium-based Z-selective cross metathesis, highlighting the advantages of this method over less efficient ways to form Z olefins.
متن کاملThe Trail Pheromone of the Venomous Samsum Ant, Pachycondyla sennaarensis
Ant species use branching networks of pheromone trails for orientation between nest and resources. The current study demonstrated that workers of the venomous samsum ant, Pachycondyla sennaarensis (Mayr) (Hymenoptera: Formicidae: Ponerinae), employ recruitment trail pheromones discharged from the Dufour's gland. Secretions of other abdomen complex glands, as well as hindgut gland secretions, di...
