LACK OF EVIDENCE FOR A NEMATODE VECTOR OF BLUEBERRY LEAF MOTTLE VIRUS (BBLMV)
Jersey highbush blueberry for potential virus vector nematodes beneath blueberry leaf mottle virus (BBLMV)-infected bushes failed to show any consistent association between Xiphinema americanum or Longidorus sp. and BBLMV-infected bushes. Trichodorus sp., however, were consistently associated with BBLMV-infected bushes, but this nematode is ubiquitous in highbush blueberry plantations.
Nematodes of all genera washed from soil from beneath BBLMV-infected blueberry bushes were negative for BBLMV when tested by radioimmunoassay.
Xiphinema americanum and Longidorus sp. washed from soil from beneath BBLMV-infected bushes and given inoculation access to Nicotiana clevelandii failed to transmit the virus.
Five species of perennial weeds growing beneath BBLMV-infected bushes supporting a low population of X. americanum were negative for BBLMV when assayed on Chenopodium quinoa. The same was true when three species of perennial and four species of annual weeds growing beneath BBLMV-infected bushes supporting a low population Longidorus sp. were assayed on C. quinoa.
Soil taken from beneath BBLMV-infected bushes containing six X. americanum 100 c3 was baited with C. quinoa, N. clevelandii and cv.
Jersey blueberry seedlings for a 3-week period.
Tops and washed roots assayed negatively for BBLMV on C. quinoa.
