title: Transmission of Pinewood Nematode Through Feeding Wounds of Monochamus carolinensis (Coleoptera: Cerambycidae).
abstract: Transmission of pinewood nematode, Bursaphelenchus xylophilus, to mature, field grown Scots pines through feeding wounds of Monochamus carolinensis was investigated by caging nematode-infested beetles on pine branches for 24 hours. Nematodes were transmitted to 31 of 64 branches. Frequency of successful transmission was independent of the sex of the beetle but dependent upon beetle age. Transmission frequencies were highest for beetles 2, 3, and 4 weeks after emergence as adults. The number of nematodes transmitted per branch was low and did not differ between beetle sexes or among beetle age categories. The number of nematodes extracted per branch was correlated with the number of nematodes carried per beetle but was not correlated with the feeding area on the branch.
