Abstract

The trails of Camponotus modoc Wheeler follow perennial routes. The ants orient along these using both chemical and visual cues. If the chemical cues are disrupted the ants reform the trail while orienting by visual cues. They can respond to the same visual cues after at least 12 h, and since no evidence was found that the chemical cues survive the winter, probably after 6 months.

Résumé

Les sentiers de Camponotus modoc suivent des tracés à caractère pérenne. Les fournis s’orientent le long de ces tracés en utilisant des signaux chimiques et visuels. Si les signaux chimiques sont éliminés, les fourmis reconstituent le sentier en s’orientant à partir de signaux visuels. Elles peuvent répondre aux mêmes signaux visuels après au moins 12 h, et puisque rien n’indique que les signaux chimiques persistent durant l’hiver, probablement après 6 mois.
