Fig. 4From: Cucumber mosaic virus and its 2b protein alter emission of host volatile organic compounds but not aphid vector settling in tobaccoSummary of the aphid free choice assays performed under normal illumination and in darkness. Aphids (M. persicae) showed a marginally lesser tendency to settle upon plants infected with CMV than on mock-inoculated control plants at 0.25, 1 or 24 h post-placement when the experiment is done under normal illumination (95% credible interval for the probability of settling on an infected plant conditional on settling was 0.36–0.48 for p 0.25 , 0.40–0.49 for p 1, 0.40–0.49 for p 24) or under continuous darkness. Under continuous darkness aphids showed a tendency to discriminate against settling on plants infected with CMVΔ2b, although 0.5 was contained in all 95% credible intervals. Under normal illumination and in continuous darkness there was no apparent tendency for aphids to discriminate between CMV- or CMVΔ2b-infected plants. The labelling of the y-axis shows the pair of plants being tested (Fny-CMV, Fny-CMVΔ2b, and mock-inoculated plants) and the conditions (normal illumination cycle or continuous darkness) under which the test was carried out. The x-axis showed the range of the 95% credible interval of the parameters p 0.25, p 1 and p 24, the probabilities of choosing to settle on an infected plant conditional on settling at t = 0.25 h, t = 1 h and t = 24 h, respectivelyBack to article page
