No controls are necessary for the deodar weevil in forest stands. Deodar cedars growing in yards, parks and along city streets are hosts of this weevil and should be kept in a healthy condition. Damaged terminals are often attacked by the weevils. The fungus Botriyosphaeria dothidea has been isolated from damaged terminals also and can cause a progressive dieback of the tree if the dead wood is not pruned properly. The southern pine root weevil Hylobius aliradicis , occasionally damages the roots of seedling and sapling- sized loblolly and slash pines in southern Georgia.
Damage appears to be worse in droughty years and on stressed trees.
The larvae bore extensively in the root collar area of the trees. These pupal cells can he found under the bark at or below the ground line in dying trees. This weevil historically has been a serious problem in cotton, peanuts, okra, velvetbeans. The larvae and adults have been observed feeding on more than 380 species of plants. The larvae feed on the roots, whereas, the adults feed on other plant parts above the ground.
