Figure 4. Aversion to EA in adults is not due to exposure to odors from the larval environment.

Proportions of untreated M. sexta larvae (light bars) and adults (dark bars) that had an EA-impregnated gel added to their pupal case (N = 40 adults, 30 larvae), and of shock+odor conditioned larvae whose pupal cases were washed (N = 39 adults, 31 larvae), that chose ambient air over EA in the Y choice apparatus. * (p<0.05) or ** (p<0.01) indicates values that differ significantly from random choice (dashed horizontal line) by a two-tailed binomial calculation. Values are means±SD.
