Abstract
The larvae of Drosophila exhibit osmotropotaxis. At high concentration s of the odorant, chemotactic response is strongly oriented. At low co ncentrations oriented crawl is replaced by quasi-random turning. If th e olfactory sensillum is ablated unilaterally, the larvae turn so as t o present the ablated side to the odour source.
