Influence of the Potato leafroll virus and virus-infected plants on the arrestment of the aphid, Myzus persicae
Journal of Insect Science 6 (22), 1-8
Abstract: A series of experiments was conducted using membrane sachets containing MP148 diet or phosphate-buffered sucrose with and without purified Potato leafroll virus to determine if direct encounter with the virus would arrest the aphid, Myzus persicae (Sulzer) (Homoptera:Aphididae). In only two out of 36 tests were there significantly more aphids settled on sachets containing the virus. In all other tests, there were either significantly fewer aphids on sachets containing virus or there were no differences between virus treatments and control sachets without virus. In an experiment using excised Physalis floridana leaves, twice as many M. persicae settled on virus-infected leaves as on noninfected control leaves. Taken together, the results indicate that arrestment of M. persicae on potato leaf roll virus-infected plants may be due to enhanced nutritional qualities resulting from disease, but not from direct encounter with or detection of the virus.
