The effects of soil moisture, mineral nutrition and
temperature on the susceptibility of peas to inoculation
with bean yellow mosaic virus (BYMV) by the green peach
aphid, Myzus persicae (Sulz.) were investigated along with
three vector-virus relationships. In addition, a comparative
study was made of two methods of evaluating susceptibility...
Experiments were done to determine the effect of some
factors on the level of transmission of bean yellow mosaic
virus (BYMV) by aphids. The effect of different source
plant treatments, the effect of light on test plant susceptibility,
and the effect of a second virus on the transmission
of BYMV...
The effects of the inherent transmissibility of the
virus and of the inherent transmitting ability of aphids
on the transmission of bean yellow mosaic virus (BYMV)
were studied along with four virus-vector relationships of
BYMV and the green peach aphid, Myzus persicae (Sulz.).
In addition, investigations were made on the...
A method of culturing Eriosoma pyricola on detached root pieces
was developed to ensure a regular supply of aphids for experimental
work. Another method was designed for studying the alate sexuparae
formation in woolly pear aphid, whereby growing plants were infested
so that the aphids or their progeny could be...
The use of petroleum oil prevented, to varying degrees: the
transmission of three stylet-borne viruses in three different crops.
The use of oils resulted in a marked improvement in the number of
lily bulbs harvested from treated plots as compared to the number of
lily bulbs harvested from untreated plots....
