| diversity of ampeloviruses in mealybug and soft scale vectors and in grapevine hosts from leafroll-affected vineyards. | the occurrence and diversity of grapevine leafroll-associated virus 1 (glrav-1) and grapevine leafroll-associated virus 3 (glrav-3) in the soft scales parthenolecanium corni and pulvinaria innumerabilis and in the mealybug pseudococcus maritimus was determined in leafroll-affected vineyards in the finger lakes region of new york. groups of 1 to 4 specimens were collected under loose grapevine bark and tested by reverse-transcription polymerase chain reaction (rt-pcr) for segments of the second d ... | 2009 | 19740031 |
| grapevine leafroll-associated virus 1 occurs as genetically diverse populations. | the genetic diversity of thirty-four isolates of grapevine leafroll-associated virus 1 (glrav-1) from different wine, table and ornamental grape cultivars in california, new york and washington states in the u.s.a. was investigated. segments of the heat-shock protein 70 homolog (hsp70h) gene, coat protein (cp) gene, coat protein duplicate 2 (cpd2) gene and orf9 (p24) were amplified by rt-pcr, cloned and sequenced. a pairwise comparison of nucleotide sequences revealed intra- and inter-isolate se ... | 2011 | 21830956 |
| slowing the spread of grapevine leafroll-associated viruses in commercial vineyards with insecticide control of the vector, pseudococcus maritimus (hemiptera: pseudococcidae). | vineyards were surveyed for grapevine leafroll-associated viruses and their insect vectors in new york state's finger lakes region in 2006-2008. grape mealybug, pseudococcus maritimus (erhorn) (hemiptera: pseudococcidae), european fruit lecanium, parthenolecanium corni (bouche), and cottony maple scale, pulvinaria acericola (walsh and riley) (hemiptera: coccidae) were identified as vector species in this region. an increase in the incidence of grapevine leafroll-associated virus 1 (glrav-1) and ... | 2015 | 26223949 |
