| The different geotactic behaviour of the two species of cercariae brings them into the ecological range of their different second intermediate hosts. |
| Emerging adults exhibit a negative geotactic response, rising up in the cage to a boll-weevil trap where they can be easily removed and counted. |
| The obstacle wall provides a geotactic barrier by presenting a side wall and an obstacle wall with numerous identical elevations. |
| As the insect climbs the surface, the geotactic response mode would provide positive reinforcement while the olfactory modality would provide negative reinforcement. |
| The present study was conducted to determine whether A. invadans zoospores show geotactic behaviour compared to other Oomycete genera. |
