Black vine weevil (BVW) is probably more common than strawberry root weevil or rough strawberry root weevil in New England. The life cycle and management of these weevils are the same. Their larvae are whitish, crescent-shaped larvae and 1/4 to1/2 inch long with no legs. Black Vine Weevil beetle (Otiorhynchus sulcatus) aka: Taxus weevil is a very serious pest both landscape plantings and in nursery and greenhouse g from Europe, this pest was first seen in the United States in the early s. Today it is one of .
The efficacy of various monitoring devices for Otiorhynchus sulcatus were compared beneath the canopies of yew trees (Taxus cuspidata) in Connecticut in and Pitfall traps captured adults/trap, while catches of trap-boards and cardboard wafers averaged Cited by: 4. The black weevil of the vine is about 1/5-inch long and mostly black in color. It is slightly larger than the strawberry root weevil, but the two are difficult to distinguish. The larvae of the black weevil on the vine feed on the roots of the target plant.
Introduction. The vine weevil (Otiorhynchus sulcatus F.; Coleoptera: Curculionidae) is a polyphagous insect feeding on many plant species from very distantly related plant current host‐plant list is based on laboratory studies of feeding, performance and field observations of damage by larvae and adults on nurseries and in ornamental plantings in parks and by: The black vine weevil, Otiorhynchus sulcatus (Fabricius), earned its name "vine" weevil as it was first documented as a pest on grapes in Germany. It has been reported as being accidentally imported from Europe and was first detected in Connecticut in However, there is evidence in the scientific literature that this species was actually detected as early as the s.
