Single aphids ( Myzus persicae ) were allowed sequential access to two leaves which were either free from infection or infected with potato virus Y° (PVY°). PVY N . beet mosaic virus (BMV), or tobacco mosaic virus (TMV). Aphids given prior or subsequent access to PVY N ‐infected leaves transmitted PVY° and BMV less frequently than aphids given prior or subsequent access to virus‐free leaves; those given prior or subsequent access to BMV also transmitted PVY° less frequently. However, prior or subsequent access to PVY° did not decrease transmission of either BMV or PVY N , and access to BMV did not decrease transmission of PVY N . Access to the non‐aphid‐transmissible TMV did not affect transmission of either PVY° or PVY N . PVY N had the greatest electrophoretic mobility. BMV was least mobile and PVY° was intermediate, so ability to decrease transmission was not directly related to the total anionic charge on the virus particles.
