Figure 1. Transmission of PaLCuCNV by four species of the B. tabaci complex.
Percentages of tomato plants infected by the virus as a function of the number of whiteflies per plant were assessed at 30th day after an inoculation access period of 48 h by viruliferous adults. Frequencies of virus-infected versus uninfected plants between the four whitefly species at each of the three whitefly densities were compared by a 2 × 4 test of independence; for easy comprehension of the comparison between the species, frequency data are presented as percentages in the diagram.
