| Studies suggest that frugivorous bats search and select fruit mainly by olfaction so that they can be attracted by smell alone. The aim of this study was to evaluate, in captivity, the behavioural response (number of foraging attempts) of Artibeus lituratus and Carollia perspicillata offered essential oils extracted from ripe fruit of Ficus insipida (Moraceae) and Piper hispidum (Piperaceae) as well as intact fruit wrapped in gauze to attract bats with reduced visual stimuli. Based on previous reports, we hypothesized that A. lituratus would exhibit preference for Ficus fruits/oil while C. perspicillata would prefer Piper fruit/oil. Four arrangements of these attractants were tested in triplicate: P. hispidum fruit vs. F. insipida fruit, P. hispidum oil... |
