title: Importance of tactile and olfactory cues to the inhibition of the grasshopper mouse's attack through toxicosis.
abstract: This study examined the effect that toxicosis paired with the presence of a distinctive texture had on the inhibition of the grasshopper mouse's predatory attack. The first experiment measured the context in which tactile cues would be most effective by presenting prey with various combinations of added stimuli. The combination of distinctive tactile, olfactory, and gustatory cues produced the longest lasting inhibition. Because certain manipulations also had an unintended weak odor associated with them, the second experiment measured the importance of a weak or strong odor to inhibition of a mouse's attack. A combination of strong odor and distinctive texture paired with toxicosis inhibited an attack more effectively than a weak odor and a similar texture. In a third experiment, toxicosis was paired with an acraea moth caterpillar which has a highly distinctive texture. This produced the longest lasting inhibition of mouse's attack observed thus far. The ecological significance of a combination of a distinctive texture and odor to the inhibition of the grasshopper mouse's attack is discussed.
