I am searching for any example insect species of the plant virus which was previously reported as non-vector the in later investigation it was found to be good vector of same virus, due to Genetic Diversity within Virus genome?
Vector biotypes of the whitefly Bemisia tabaci are a good example, specifically the whitefly-transmitted begomoviruses by whitefly biotype A, B, C, Q,, are presently associated with severe diseases in tomatoe, cotton, beans and cassava. There are many references about the family Geminiviridae transmitted by whiteflies.
Finally I got couple of references.
BYDV-GAV is transmissible by Schizaphis graminum as well as Sitobion avenae, which earlier reported to be transmitted only by Sitobion avenae (Zhou et al., 1987; Wang et al., 2001).
Similarly, Damsteegt et al. (2011) had discussed Aphis glycines as vector of Soyabean dwarf virus isolates (SbDV) which was always reported as a pest of soybean that did not transmit SbDV except for one report.
