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.

What is the common name of Otiorhynchus sulcatus?
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.
What is the scientific name of the strawberry root weevil?
Otiorhynchus ovatus is the binomial, Latin or scientific name of the strawberry root weevil. Despite its name, it's a serious pest of azaleas. It attacks vulnerable plant body parts above and below ground.Specifically, the larval stage damages the roots, by which the plant takes in necessary dissolved nutrients from the soil. The adult stage damages the leaves. In the aftermath of its feeding, the leaves are notched or scalloped along the margins. They also may curl, droop or yellow.A soil drench with the active ingredient imidacloprid tends to take care of the larval damage. A treatment with the active ingredient acephate tends to take care of the adult damage above ground. But it may need to be applied every three weeks, summer through September.
What causes notching or scalloping of the leaves and chewing of the bark at the base of the stem of azaleas?
Adult weevil damage typically is seen in notching or scalloping of leaves and chewing of the bark at the base of stems. Leaves often may be left yellowed, drooping or curled. In terms of azaleas, the weevil in question is either the black vine weevil [Otiorhynchus sulcatus] or the strawberry root weevil [Otiorhynchus ovatus].Adult weevils are black or gray. They have quite noticeable 1/4 - 3/8 inch [0.635 - 0.9525 centimeter] snouts by which they feed. They will be found on the leaves for night-time feeding. So it's later in the day they can be controlled by treatments with the active ingredient acephate, if need be every three weeks summer through September.The larval stage also feeds on azaleas. They cause even more damage than the adults. The 1/4 - 1/2 inch [0.635 - 1.27 centimeter] legless grubs are in the soil, to feed on the azalea's roots. So that's where they'll be controlled by a soil drench, such as with imidacloprid.
