Abstract:
Cucumber mosaic virus (CMV) was transmitted more efficiently by Aphis gossypii. Pre-acquisition starvation for four hours was beneficial. Around 20 and 30 minutes of acquisition access period with 20 min of inoculation feeding period was required for transmitting 100 per cent CMV virus, when 10 aphids per plant were released. Thirty min. acquisition feeding period and one hour of inoculation feeding period showed maximum per cent of CMV transmission. Minimum 10 aphids were required for the 100 per cent transmission of virus. Feeding aphids lost infectivity after one hour. The studies indicated non-persistent relationship of CMV with A. gossypii.
