Virus - Vector relationships of yellow vein mosaic virus and whitefly (Bemisia tabaci) in pumpkin
2002
and SABITHA DORAISWAMY, K. JAYASHREE*, K.B. PUN
Pumpkin yellow vein mosaic virus was transmitted to healthy pumpkin plants only by B. tabaci and not through sap inoculation. A single viruliferous whitefly was able to cause 21.67% infection but 100% infection was obtained when 15 whiteflies were used per plant. The acquisition threshhold and the inoculation threshhold periods for the whitefly were 6 h and 3 h, respectively. The percentage of transmission increased with increase in both acquisition and inoculation feeding periods. A pre-acquisition starvation period of 3 h gave 100% transmission, but post-acquisition starvation was found to reduce the transmission efficiency.
