The results of studies involving aphid trapping and natural virus infection of test plants showed that A. gossypii played an important part in cucumber and gherkin infection by CMV, which occurred most frequently in August. However, only a small percentage of any of the aphids found was responsible for virus transmission. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Satellite RNAs (satRNAs) are associated with Cucumber mosaic virus (CMV) in tomato, most often causing severe epidemics of necrotic plants, and not associated with specific host symptoms. Laboratory studies on virus transmission by the aphid vector Aphis gossypii were performed to better understand the dynamics of field populations of CMV. The presence of satRNAs correlated with lower concentrations of virus in infected plants and with a decrease in the efficiency of transmission from satRNA-infected plants. Both the concentration of virus in CMV-infected tomato and the efficiency of transmission varied more extensively with nonnecrogenic satRNAs than with necrogenic satRNAs. A negative effect of satRNAs on virus accumulation can account, in part, for a decrease in the field transmission and recovery of CMV + satRNAs. Aphids behaved differently and probed less readily on plants infected with CMV + necrogenic satRNAs compared with plants containing non-necrogenic satRNAs. Aphid-mediated satRNA-free CMV infections were observed in test plants when aphids were fed on source plants containing CMV + nonnecrogenic satRNA; no comparable satRNA-free test plants occurred when aphids were fed on source plants containing necrogenic satRNAs. These results indicate that factors associated with transmission can be a determinant in the evolution of natural populations of CMV and its satRNA.

Entomological aspects of the epidemiology of cucumber mosaic virus (CMV) were studied in Michigan. Myzus persicae (Sulzer) and Aphis gossypii Glover were efficient vectors of CMV between various hosts in the laboratory. Macrosiphum euphorbiae (Thomas) transmitted CMV between cucumber and Echinocystis lobata (Michx.) T. & G. Myzocallis asclepiadis (Monell) was shown to be a new vector of CMV between Asclepias syriaca L. Neither Melanoplus differentialis (Thomas) nor Acalymma vittata (Fabricius) transmitted the virus in limited trials.There was a small proportion of cucumber plants infected early in July, when alate M. persicae were present. In August the incidence of infection rose rapidly after a period of activity of alate A. gossypii. Alate aphids were trapped in yellow water pans situated in and around cucumbers. Seven known vectors of CMV were caught.

Resistance Evaluation of Chillipepper Cultivars for Cucumber Mosaic Virus and Chilli Veinal Mottle Virus.  The use of resistance culivars is an important strategy for management of virus infection in chillipepper. A research was undergone to study the effect of single and mix infection of CMV and ChiVMV on the disease incidence and on the growth and yield of nine chillipepper cultivars, i.e. Cilibangi 4, Cilibangi 5, Cilibangi 6, Helem, Jatilaba, Tit Bulat, Tit Segitiga, Tit Super and Tampar. Mechanical inoculation was conducted to transmit the virus. Infection of the virus was then confirmed with DAS-ELISA.  In general, inoculated chillipepper cultivars developed similar symptoms, i.e. mosaic type for CMV and mottle type for ChiVMV.  More severe symptom was not always observed from mix infection of CMV and ChiVMV. Disease incidence occurred in the range of 16.67 – 86.0% and this caused 18.3 – 98.6% yield loss.  Based on symptom expression, ELISA result, and reduction on yield, it can be concluded that all chillipepper cultivars used in this study could not hold up the virus infection. However, several cultivars showed tolerance response :  Jatilaba, Tit Super, and Tampar for CMV; Cilibangi 4 for ChiVMV; Tit Super for mix infection; and Cilibangi 5 for CMV, ChiVMV, and mix infection.  Further evaluation and investigation involving different chillipepper cultivars should be conducted.

Symptom Phenotype

ABSTRACT A hybrid virus (CMVcymMP) constructed by replacing the movement protein (MP) of cucumber mosaic cucumovirus (CMV) with that of cymbidium ringspot tombusvirus (CymRSV) was viable and could efficiently spread both cell to cell and long distance in host plants. The hybrid virus was able to move cell to cell in the absence of functional CP, whereas CP-deficient CMV was restricted to single inoculated cells. In several Chenopodium and Nicotiana species, the symptom phenotype of the hybrid virus infection was clearly determined by the foreign MP gene. In Nicotiana debneyi and Nicotiana tabacum cv. Xanthi, the hybrid virus could move systemically, contrary to CymRSV.
