Caption: Functional calcium imaging in the antennal lobes of a female Manduca sexta moth: Different activation patterns (red spots) can be observed depending on whether the moths respond to (Z)-3-hexenyl acetate or (E)-2-hexenyl acetate. The odor of a (Z)-3-isomer or a (Z)-3 / (E)-2 ratio in favor of a (Z)-3-isomer -- according to the odor bouquet of an unattacked plant -- guides ovipositing Manduca females to plants that have yet been spared by herbivorous caterpillars.
