A virus with elongate particles (656 nm) was isolated from several Lonicera species. This virus, apparently belonging to the carlavirus group, is serologically distantly related to shallot latent virus and closely related to poplar mosaic virus. The inability to infect poplar and two other hosts of poplar mosaic virus characterizes the virus from Lonicera as a new virus which was named Lonicera latent virus.The virus was easily sap-transmissible but was not transmitted by Myzuspersicae. Dilution end-point was about 10-3, thermal inactivation between 65 ~ and 80 ~ and ageing in vitro 1-6 days.Heat treatment, combined with tip-rooting appeared to be a good method to eliminate the virus from several Lonicera species and cultivars.Additional keywords." Nicotiana megalosiphon, virus adaptation, yellow vein mosaic of Lonicera japonica.
