What is the Latin name of the black vine weevil?

'Otiorhynchus sulcatus' is the binomial, Latin or scientific name of the black vine weevil. It leaves notched or scalloped margins to azalea leaves from its night-time feeding. It also may cause these same leaves to yellow, droop or curl. Additionally, it even may chew away at the bark at the base of the stem. The larval stage of this weevil is known to attack the plant's roots.

A soil drench, such as with Imidacloprid, may take care of the grubs below ground. A pesticide with the active ingredient of acephate may take care of the adult weevils above ground. The treatment may need to be carried out every three weeks, summer through September.
