Black vine weevil is the common name of Otiorhynchus sulcatus. It's one of two weevils whose feeding leaves azalea leaves notched or scalloped along the margins. The feeding also may cause the leaves to yellow, drop or curl. Additionally, the larval stage of these two weevils tends to attack the plant's roots.
It's considered a serious pest. The grubs may be controlled below ground by a soil drench, such as with imidacloprid. The adults above ground may need treatments every three weeks throughout the summer with the active ingredient acephate.

Strawberry root weevil is the common name of Otiorhynchus ovatus. Along with the black vine weevil [Otiorhynchus sulcatus], it's a serious pest of azalea leaves and roots. The adult feeds on the leaves, which are left with notched or scalloped margins. The leaves also may yellow, droop, or curl. The larval stage hatches from eggs the adult lays at the base of stems. They burrow down through the ground to the roots.Adults are night-time feeders. So they best are controlled by treatments with the active ingredient acephate late in the day. Grubs best are controlled by soil drenches with the active ingredient imidacloprid.

There are four currently accepted species in the genus Stegosaurus. They are Stegosaurus armatus, Stegosaurus stenops, Stegosaurus sulcatus, and Stegosaurus longispinus.
'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.
