Pissodes nemorensis, known generally as the eastern pine weevil or deodar weevil, is a species of true weevil in the beetle family Curculionidae. It is found in North America and Africa. Deodar weevils are considered a forest pest in the United States, with adults and larvae feeding on a variety of coniferous tree species, including trees such as deodar cedar, loblolly pine, longleaf pine, sand pine, shortleaf pine, slash pine, and spruce pine Trees of all ages are susceptible to weevil infestations, while trees that are severely stressed by fire, drought, extreme cold, fusiform rust, wind damage, and other problems are prone to weevil infestation. In well-managed pine stands, deodar weevil infestations are sporadic, attacking only the suppressed and unhealthy trees throughout the area. Because they do not typically effect healthy trees, they do not usually alter traditional management strategies. Unlike many other forest pests in the eastern United States, deodar weevils are most active in the winter months, and this is often when sign of infestations can be seen. The best way to avoid a deodar weevil infestation is to maintain good tree and stand health: healthy trees do not typically face mortality or extensive damage from these pests. If an infestation has occurred, pesticides can be used in the fall as the weevils become active, but are typically not recommended.
