Longevity and detection of persistent foraging trails in Pharaoh’s ants, Monomorium pharaonis (L.)
Pheromone trails provide a positive feedback mechanism for many animal species, and facilitate the sharing of information about food, nest or mate location. How long pheromone trails persist determines how long these environmental memories are accessible to conspecifics. We determined the time frame over which Pharaoh’s ant colonies can re-establish a long-lived trail and how the behaviour of i...
متن کاملThe allocation of foragers in red wood ants
1. We studied how colonies of the red wood ant, Formica polyctena, adjust the numbers of foragers allocated to different foraging trails. In a series of field experiments, foragers were marked and transferred from one nest to another, related nest, where they joined the foraging force. Transferred workers acted as a reserve of uncommitted, available foragers. 2. Previous work shows that each in...
متن کاملSpatial and temporal variation in pheromone composition of ant foraging trails
Many social insects use pheromones to communicate and coordinate their activities. Investigation of intraspecific differences in pheromone use is a new area of social insect research. For example, interindividual variation in alarm pheromone content has been found in physical castes of polymorphic ants. Many ant species use multiple trail pheromones. Here we present novel research into trail ph...
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 کاملTriggering and persistence of trail-laying in foragers of the ant Lasius niger.
In the ant Lasius niger, the ability to ingest their own desired volume is the key criterion that rules the recruiting behaviour of scouts. This volume acts as a threshold triggering the trail-laying response of foragers. In this paper, we show that this desired volume is specific to each individual and is kept constant over successive trips to a food source. This individual specificity contras...
