A large infestation of southern pine beetle, (Dendroctonus frontalis Zimm.), located in central Louisiana, was surveyed for the pinewood nematode, Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle. Pinewood nematodes were present in 4.2 percent of 94 loblolly pine (Pinus taeda L.) trees attacked by D. frontalis and were absent from 101 unattacked trees that surrounded the infestation. Monthly sampling of this infestation revealed an increase in the incidence of nematodes as the season progressed. Samples taken from different heights on beetle infested-boles did not differ significantly in the presence of nematodes.
