Event Abstract Back to Event Odor effects on innate color preference in foraging behavior of the Japanese yellow swallowtail, Papilio xuthus Michiyo Kinoshita1*, Mina Yoshida1, Basil El Jundi2, Uwe Homberg3 and Kentaro Arikawa1 1 The Graduate University for Advanced Studies (SOKENDAI), Department of Evolutionary Studies of Biosystems, Japan 2 Lund University, Department of Biology, Sweden 3 Philipps-Universität Marburg, Department of Biology, Germany Papilio butterflies have sophisticated color vision and are potential pollinators for red flowers. Do they innately prefer red flowers? Is their foraging based solely on color? To answer these questions, we presented newly emerged Papilio with four colored disks (blue, green, yellow and red) on an otherwise black floor of a small cage. We defined their innate color preference as the color upon which they first land and extend their proboscis. In both sexes, more than half of individuals selected blue in the absence of odor (top bars of charts). When we performed the same test with ambient odor present, clear differences emerged between different odors as well as between the sexes. When orange flower essence (Neroli) was added, females selected either red, yellow or blue, while males mainly selected either yellow or blue (second bars). With Citrus trees present (third bars), or with both the trees and Neroli (bottom bars), the frequency of green selection significantly increased in females, but not in males. To identify the neural basis of this behavioral phenomenon, we initiated a neuroanatomical study focusing on the primary olfactory ganglion, the anntenal lobe (AL). The AL is composed of about 60 glomeruli. One glomerulus in the dorsolateral AL is found only in males, while three glomeruli in the ventrolateral AL are enlarged in females; this sexual dimorphism may be related to the sexual difference in behavior. We also inspected the brain areas where visual and olfactory information are integrated. Local dye injection revealed that outputs of both the optic lobe and the AL innervate the calyces of the mushroom body (MB), suggesting that the MB integrates vision and olfaction in Papilio, as in hymenopterans.
