The region most-affected has been the Central Plains from Kansas to Southern South Dakota (up to about I-90). The disease has been found in Southern South Dakota during the past several decades. It periodically results in outbreaks, with many trees lost in a specific community or county for a year or two. The disease affects exotic pines, Austrian, Scotch, and Mugo; our native pines, ponderosa pine for example, are not killed by the disease. The disease also appears on older trees, and you usually do not see it on pines younger than 10-to-15 years in the landscape as can be noted in the picture.

What are sawyers in North Carolina?
Southern pine sawyers, Monochamus titillator, are longhorned beetles that are common in North Carolina. These beetles are up to 1.5 inches long and are mottled and blend in with pine bark. The “horns” are actually antennae that often much longer that the rest of the insect. Southern pine sawyers are very sensitive to the health of pines. Very soon after a pine reaches the "point of no return" or is cut down, adult sawyers soon fly in to chew oval, conical holes in the bark in order to lay eggs underneath. Sawyer larvae hatch and bore in the sap wood for a while excavating shallow tunnels filled with wood fibers and frass. These roundheaded borers are legless and fairly slender. Older larvae then tunnel directly into the heart wood and before pupating close to the bark about a year later. The larvae are called roundheaded borers because their tunnels are round. They are called sawyers because as they feed, these grubs make a clicking or rasping noise that can be heard several feet away. In addition, “sawdust” accumulates around the base of infested pines. Adults molt from the pupae and emerge by chewing round holes in the bark. New adults feed on the bark of healthy pines before mating and laying eggs. In warm weather, sawyers develop from egg to adult in about two months. Development and adult activity is much slower in cold weather. This is a main reason pines are best cut in the winter for log homes. In warm weather southern pine sawyers soon infest newly cut logs and degrade the wood with their tunnels. Pinewood nematodes are carried by sawyers and perhaps other beetles. New sawyers feed on the bark of pine twigs and infest the new tree with nematodes from the tree the beetle emerged from. Because sawyers feed on the bark of healthy trees, it is possible for such trees to become infested with pinewood nematodes at that time.
