Among the different environmental signals, olfactory cues are critically important for foraging, navigation, and social communication in many species, including ants. Ants use their two antennae to explore the olfactory world, but how they do so remains largely unknown. In this study, we use high resolution videography to characterize the antennae dynamics of carpenter ants (Camponotus pennsylvanicus). Antennae are highly active during both odor tracking and exploratory behavior. When tracking, ants used several distinct behavioral strategies with stereotyped antennae sampling patterns (which we call Sinusoidal, Probing, and Trail Following). In all behaviors, left and right antennae movements were anti-correlated, and tracking ants exhibited biases in the use of left vs right antenna to sample the odor trail. These results suggest non-redundant roles for the two antennae. In one of the behavioral modules (Trail Following), ants used both antennae to detect trail edges and direct subsequent turns, suggesting a specialized form of tropotaxis. Lastly, removal of an antenna resulted not only in less accurate tracking but also in changes in the sampling pattern of the remaining antenna. Our quantitative characterization of odor trail tracking lays a foundation to build better models of olfactory sensory processing and sensorimotor behavior in terrestrial insects.<\/jats:p>","DOI":"10.1242\/jeb.185124","type":"journal-article","created":{"date-parts":[[2018,9,28]],"date-time":"2018-09-28T04:35:44Z","timestamp":1538109344000},"source":"Crossref","is-referenced-by-count":48,"title":["Carpenter ants use diverse antennae sampling strategies to track odor trails"],"prefix":"10.1242","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8198-1469","authenticated-orcid":false,"given":"Ryan W.","family":"Draft","sequence":"first","affiliation":[{"name":"Center for Brain Science, Harvard University, Cambridge, MA, USA; Department of Molecular & Cellular Biology, Harvard University, Cambridge, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew R.","family":"McGill","sequence":"additional","affiliation":[{"name":"Program in Neuroscience, Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vikrant","family":"Kapoor","sequence":"additional","affiliation":[{"name":"Center for Brain Science, Harvard University, Cambridge, MA, USA; Department of Molecular & Cellular Biology, Harvard University, Cambridge, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2443-4252","authenticated-orcid":false,"given":"Venkatesh N.","family":"Murthy","sequence":"additional","affiliation":[{"name":"Center for Brain Science, Harvard University, Cambridge, MA, USA; Department of Molecular & Cellular Biology, Harvard University, Cambridge, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","published-online":{"date-parts":[[2018,1,1]]},"reference":[{"key":"2021042513343458600_JEB185124C1","doi-asserted-by":"publisher","first-page":"229","DOI":"10.2307\/3493193","article-title":"Artificial diet for rearing various species of ants","volume":"53","author":"Bhatkar","year":"1970","journal-title":"Fla.
