In many situations, it is difficult to evaluate the location of nests of ants, especially in tropical systems, or to determine which trail system corresponds with which nest, as in the case of high‐density populations of leaf‐cutting ants, Atta spp. Fragments of colored drinking straws coated with an attractant, generally vegetable oil and/or a starchy carbohydrate, are carried by ants and following removal of the attractant are deposited in middens, allowing determination of the origin of foraging workers.
Zusammenfassung
Eine einfache Methods zur Lokalisierung von Nestern bei nahrungssuchenden Ameisen am Beispiel von Atta spp. (Hym., Formicidae)
Da es manchmal, insbesondere in den Tropen schwierig ist, Ameisennester genau zu lokalisieren oder Ameisenstraßen bestimmten Nestern zuzuordnen, wird hier eine einfache Methode dargestellt. Teile von farbigen Strohhalmen, die mit Fraßstimulantien bestreut werden (Pflanzenöl und Kohlehydrate) werden von Atta spp. gerne verschleppt. Anhand der verschleppten Nahrungspartikel kann die Herkunft der nahrungssuchenden Ameisen bestimmt werden.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
