For the control of Vine WeevilBlack vine weevil [i]Otiorhynchus sulcatus[/i] is a major pest of nursery stock, pot plant and soft fruit production. Leaf notches around the edge of leaves indicates damage by adult weevils, this is when egg laying begins.

Adults are all female, approximately 10mm long, and can lay up to 1000 eggs between June and October but over a longer period under protection. The larvae feed mainly on roots but they will also eat corms and soft fleshy stems.

It takes several months to develop from egg to adult resulting in one cycle per year on outdoor crops but multiple generations may occur on heated crops.
