Thomas and Krishnaswami (784) first reported in 1939 this species as a vector of little leaf of brinjal (eggplant). However, only one of nine plants tested became diseased. There are no records confirming transmission, and it is unlikely that the Species will become important as a vector owing to its association with cotton.
