cherries are severely impacted, resulting in tasteless fruits, lacking both sweetness and flavor. Other cultivars show symptoms similar to those in
Lambert, but usually less severe and more varied. Typically, dark-fruited cultivars show more severe fruit symptoms than cultivars with red or yellow fruit. The ability to recover is also dependent on cultivar, with some able to return to fruit sizes and coloring comparable to uninfected trees. The taste, however, never recovers.

Little cherry virus-1 is spread by an unknown vector. Little cherry disease likely originated in Japan and spread with ornamental cherry trees world-wide; many of the

Some sweet cherry cultivars display foliage symptoms, with the fruit crop less hidden by the canopy, and leaf symptoms, varying from a slight marginal up-curl of the leaves to marked reddening of leaf surfaces. The general vigor of infected trees may be impaired, though this is not always apparent.

production in the region resumed in 1996 after mandatory control programs had been put in place. In 1938, parasitic wasps were introduced to the area as biocontrol agents in an attempt to manage the apple mealy bug population, with some success in limiting the speed at which the viruses spread.

In infected trees of the commercially important cultivar
Lambert, the fruit develops normally until about ten days before harvest, when maturation stops. At picking time, the cherries are 1/2–2/3 of the regular size, dull in color, with an angular pointed shape. The sugar and acid levels of the

There is no known cure for little cherry disease and tolerance breeding programs have not yielded any cultivars able to withstand the effects of the disease for more than a few seasons. Thus, prevention of spread has been the focal point in combating the disease.

Due to considerable genetic variation among strains, isolates from both viruses have previously been designated as belonging to new and separate species before being reassigned to one of the two recognized viruses.
