Pathotypes of the Pinewood Nematode Bursaphelenchus xylophilus.
An isolate of Bursaphelenchus xylophilus from Pinus sylvestris in Missouri infected and reproduced in 2-3-year-old seedlings of P. sylvestris and to some extent in seedlings of P. nigra. Wilting, however, occurred only in P. sylvestris. B. xylophilus isolated from P. strobus in Vermont infected and reproduced only in P. strobus seedlings. P. taeda seedlings were resistant to both of these isola...
متن کاملPinewood Nematode, Bursaphelenchus xylophilus, Associated with Red Pine, Pinus resinosa, in Western Maryland.
Red pines Pinus resinosa in Garrett and Allegany counties, Maryland, were examined during 1982-84 to determine distribution of the pinewood nematode, Bursaphelenchus xylophilus, within and among trees. Approximately 25-year-old (younger) and 47-year-old (older) trees were subdivided into the following categories: 1) trees with mostly green needles; 2) trees with mostly reddish-brown needles; 3)...
متن کاملWithin-wood Spatial Dispersion of the Pinewood Nematode, Bursaphelenchus xylophilus.
Pinewood nematode, Bursaphelenchus xylophilus (Steiner &Buhrer) Nickle, spatial dispersion was determined in Scots pine, Pinus sylvestris L., bolts infested with the pine sawyer beetle, Monochamus carolinensis (Olivier) and in bolts without M. carolinensis. According to Taylor's power law and Green's index of dispersion, nematode dispersion was aggregated in both sets of bolts. The degree of ag...
متن کاملCharacterization of Bacteria Associated with Pinewood Nematode Bursaphelenchus xylophilus
Pine Wilt Disease (PWD) is a complex disease integrating three major agents: the pathogenic agent, the pinewood nematode Bursaphelenchus xylophilus; the insect-vector Monochamus spp.; and the host pine tree, Pinus sp. Since the early 80's, the notion that another pathogenic agent, namely bacteria, may play a role in PWD has been gaining traction, however the role of bacteria in PWD is still unk...
متن کاملPathogenicity of the pinewood nematode, Bursaphelenchus xylophilus, to Japanese larch, Larix kaempferi, seedlings.
Pathogenicity of the pine wood nematode, Bursaphelenchus xylophilus, to Japanese larch, Larix kaempferi, seedlings was tested with inoculation experiments under nursery conditions. Water suspensions of nematodes (mixed stages cultured on Botrytis cinerea or dispersal fourth-stage juveniles (DJ4) extracted from the adult Japanese pine sawyer, Monochamus alternatus) were injected into the stems o...
