Stone dropping by Conomyrma bicolor (Hymenoptera: Formicidae): A new technique of interference competition

  journal={Behavioral Ecology and Sociobiology},
Summary1.The dolichoderine ant Conomyrma bicolor interferes with the activity of other desert ants when their nest entrances are in close proximity. C. bicolor workers surround these nests, pick up small stones and other objects with their mandibles, and drop them down the nest entrances.2.Interactions of C. bicolor with three species of Myrmecocystus (M. mexicanus, M. mimicus, and M. depilis) were investigated. ‘Stone dropping’ and associated behaviors prevent the Myrmecocystus colonies from… Expand

Figures from this paper

Competition between Formica cinerea Mayr [Hymenoptera: Formicidae] and co-occurring ant species, with special reference to Formica rufa L.: direct and indirect interferences
The presumption that F. rufa would influence the activity of F. cinerea was not supported by the results, and the outcome of interspecific interactions within the multi-species community studied responded with the species competitive status generally. Expand
Chemical interference competition by Monomorium minimum (Hymenoptera: Formicidae)
Workers of Monomorium minimum forage above-ground for dead arthropods and extrude an irritating poison gland secretion from the sting when ants of other species are encountered at food resources, delaying invasion by competitors and prolongs the period during which the colony can dissect and retrieve pieces of the food resource. Expand
Interspecific interference behaviours by workers of the harvesting ant Messor capitatus (Hymenoptera Formicidae)
A behavioural task group of workers (defined as ‘sappers’) that have a direct detrimental effect on colony activity of heterospecific congeneric competitors are identified. Expand
Interference competition between ants (Hymenoptera: Formicidae) in Amazonian clearings
The first case of interference competition through soil dumping in South America is documented between Ectatomma quadridens and Pheidole fallax in Atnazonian forest clearings, with the prediction that interference competition is more probable as resources become more concentrated. Expand
Interference strategy of Iridomyrmex pruinosum (Hymenoptera: Formicidae) during foraging
Iridomyrmex achieves this by quickly channeling large numbers of workers to food sources and nest entrances of Myrmecocystus, employing an effective chemical mass recruitment system, and chemicall repelling its competitors with secretions from the pygidial (anal) gland. Expand
This study investigated the tool-using behaviour of Aphaenogaster subterranea in retrieving food through field observations using honey and petroleum jelly baits and found the number of workers manipulating tool items was positively correlated with thenumber of workers performing other activities. Expand
Nest-plugging: interference competition in desert ants (Novomessor cockerelli and Pogonomyrmex barbatus)
Nest-plugging by N. cockerelli decreases the foraging capacity of P. barbatus colonies and means that these colonies do not compensate for late emergence or events impeding foraging by increasing foraging rate. Expand
Long-term partitioning of space between two territorial species of ants (Hymenoptera: Formicidae) and their effect on subordinate species
Differences between the two territorial species in their use of space and competitive effects ensured their coexistence in adjacent territories over long periods of time at this particular site in Finland. Expand
The Effects of Proximity and Colony Age on Interspecific Interference Competition between the Desert Ants Pogonomyrmex barbatus and Aphaenogaster cockerelli
The results suggest that the intensity of interspecific interference competitive interactions may depend on the proximity and age of competing colonies, and the age and proximity of P. barbatus colonies. Expand
Larval Ischnura verticalis (Odonata: Coenagrionidae) Respond to Visual Cues of Predator Presence
Results suggest larvae can use vision to detect large, active predators but can also detect predators through olfaction when visual cues are unreliable. Expand


Chemische Strategie beim Nahrungserwerb der Diebsameise (Solenopsis fugax Latr.) und der Pharaoameise (Monomorium pharaonis L.)
Solenopsis fugax, a subterranean ant, lays odorous trails in the tunnels leading to the brood chambers of neighbouring ant species, and discharges a highly effective and long lasting repellent substance from the poison gland when preying on the foreign brood. Expand
