title: [Determinism of the displacements of the first stage larvae of Acrolepiopsis (Acrolepia) assectella Zell. (Lepidoptera) in the host plant].
abstract: The leek-moth digs straight mines towards the base of the plant. Experiments show that this orientation would be essentially the consequence of the morphological structure and of the physiological activity of the host-plant while geotactism had little influence on the behaviour of the leaf-miner.
