The Drosophila larva can orient its movements towards chemoattractants such as food sources using olfactory information. Almost all reports on chemotaxis of the Drosophila larva have focused on sharp turns, however as far as we know, there is no report suggesting the existence of successive slow orientations during locomotion to odorant sources. Firstly we sought to reveal from behaviors of Canton S (wild type) that the successive slow orientation, which will be named `biased running' in this study, is used as an alternative behavioral strategy of the Drosophila larva during chemotaxis. Next, to verify the contribution of stereo olfaction to the biased running during chemotaxis, we studied behaviors of unilaterally and bilaterally rescued larvae that have unilaterally functional olfactory organs and bilaterally functional ones, respectively. |
