In 2014 a paper with the following title was published: "Host-range studies, genetic diversity and evolutionary relationships of ACLSV isolates from ornamental, wild and cultivated Rosaceous species"
It was published in: Plant Pathology (2014), volumn 63, pages 63-71.

Fortunately the full paper is available free.
The virus was detected in R. canina and in R. acicularis.
In R. canina the virus was detected by ELISA in 3 or 4 of 26 samples and by PCR in 2 of 26 samples. In R. acicularis the virus was detected in 9 of 9 samples tested by ELISA and by 1 of 9 of those tested by PCR. The data are given in Table 3. Please be aware that It appears to me that there are inconsistencies in the Table (or my interpretation of it).
In the body of the article the following numbers appear (in bold):The ornamental species, ornamental plum (P. cerasifera) and ornamental (Japanese) quince (C. japonica) showed high ACLSV prevalence (28/38 and 24/62, respectively). In rose (R. canina) and C. monogyna the virus was less frequent (2/26 and 1/40, respectively) while ACLSV was not detected in P. coccinea (firethorn; 0/29)."
"ACLSV was also detected in wild Rosaceae species such as Rubus sp. (1/2), wild cherry (Cerasus nigra, 6/ 36), Prunus spinosa (5/14), P. pindicola (1/7), P. amygdaliformis (10/81), wild rose (R. acicularis, 1/9) and wild pear (P. pyraster, 1/43)."
Concerning spread:
"Even though vegetative propagation and grafting could explain virus spread and maintenance in the cultivated and ornamental plants, they cannot account for its presence in the wild species. In these hosts ACLSV could either be transmitted by seed, pollen or by a putative vector even if it has not been reported to be spread in this way (Yoshikawa, 2001)."
