Its incidence and distribution have extended manifolds in potato growing regions of India especially in seed production areas. In the recent past, it has been occurring on potato in the four agroecosystems of Shimla, Jalandhar, Modipuram and Gwalior. This study determines species distribution and its viruliferous nature with respect to most predominant viruses viz., Potato virus Yo (PVYo) and Potato leafroll virus (PLRV). Adults of A. solani (prestarved) were given an acquisition feeding of 24 hr on pure culture of PVYo and PLRV, and then released on to tissue culture raised healthy potato seedlings for inoculation. These plants were allowed for expression of external visual symptoms and were PCR tested at weekly intervals for 35 days.
