It was not until we identified the right environmental conditions that the larvae started moving freely around the chamber.
As soon as they did, they moved to the plastic pipe and started biting it and causing damage that was consistent with that seen on grower properties.
The Whitefringed weevil is a well known pest of lucerne. The larvae attack the roots of lucerne plants causing significant yield loss and sometimes death of the plant.
