Appearance

Larvae (third stage): size 0.7-0.8 mm

Other stages: develop inside host

 

Mode of action

The nematode enters the larva of the vine weevil via mouth, anus or respiratory openings and starts to feed. This causes specific bacteria to emerge from the intestinal tract of the nematode. These spread inside the insect and multiply very rapidly. The bacteria convert host tissue into products which can easily be taken up by the nematodes. The weevil larva dies within a few days.

 

Visual effect

Infected larvae colour orange-red to red-brown.
