Artibeus literatus

Neotropical bats Desmodus rotundus, Artibeus literatus, and Phyllostomus discolor) are very sensitive to butanoic acid their detection threshold lies between 1.5 x 10 ° and 1.5 x 10 mol/1 (Schmidt, 1975). The short-tailed fruit bat Carollia perspicillata) has detection thresholds for 18 odorants ranging from 3.6 x 10 to 2.7 X 10 ° molecules/cm air. The animals were most sensitive to fruit-typical compounds such as ethyl butyrate (5.4 x 10 °molecules/cm ), w-pentyl acetate (2.8 X 10 °molecules/cm ), andlinalool(1.8 x 10 molecules/cm ), suggesting nutritional specialization of chemoreception (Laska, 1990). The bats increased their respiration rate from a basal rate of 2-4 Hz to as much as 12 Hz when confronted with an odor of high concentration.
