Transmission studies of watermelon mosaic virus by aphids

ENTOMON, 1976
Comparative efficiency of four species of aphids as vectors of watermelon mosaic virus revealed Aphis gossypii as most efficient vector. Lipaphis pseudobrassicae and Aphis nerii are reported as additional vectors of watermelon mosaic virus. A detailed study of virus-vector relationship was made using made using Aphis Gossypii.
