Figure 5. The effects of inoculation access period (IAP) of the vector B. tabaci MED on the proportion of CCYV-infected cucumber plants.

After feeding CCYV-infected cucumber plants with 3 days, 30 whiteflies were placed on non-infected cucumber leaves (3–4 leaf stage) with clip cages for 1, 6, 12, 24 and 48 h, respectively. Twenty-four plants were used for each treatment and detected with RT-PCR after 30 days. Data shown are mean ± SE. Three replicates were used.
