Extract

There seems to be only one report of the aphid Myzus certus (Wlk.) transmitting a virus, bean yellow mosaic virus (Swenson, 1957). It is therefore noteworthy that M. certus transmits potato virus Y as readily as does Myzus persicae (Sulz.), until now the most efficient vector known for virus Y. In one experiment that showed this, the numbers of single aphids out of 50 that transmitted virus Y were 27 and 28 respectively. Briefly the experiment was as follows: M. certus was reared on pansy (Viola tricolor) and M. persicae on rape (Brassica napus); the strain of virus Y was the one that has been used at our laboratory for aphid transmission studies during the past ten years; single adult apterae or late instar nymphs each probed once for less than a minute into an infected tobacco plant and then fed overnight on a young healthy tobacco plant (Nicotiana tabacum var. White Burley).
