[29] There are two types of virus transmission between plant-aphid interactions: non-circulative transmission and circulative ...
Control of aphids with insecticide application is the only means of managing this problem in production years that are highly favorable for aphids. Seed borne infection generally results in small, stunted, badly impaired plants which have reduced yield both in tuber numbers and in tuber size.

[12] While feeding on a plant long term, Myzus persicae can uptake chloroplast DNA, even though the chloroplasts themselves are uninjured.
