Moths are nocturnal animals that find their host plants mainly by olfactory cues. Even closely related species often have particular host preferences and therefore should rely on different sets of potentially crucial odorants. Do the different host preferences affect the spatial and temporal coding of plant-released odorants within the moths’ brain? Using calcium imaging I am studying odour-evoked neural activity patterns in the antennal lobe, the first olfactory processing centre in insects, to compare these patterns across different moth species (e.g. hawk moths, silk moths, owlet moths). That way I am aiming to unravel the impact of phylogenetic relationships and diverging life histories on the olfactory code in moths.
