Acquisition of Fiji disease virus by Perkinsiella saccharicida kirk and observations on its instars

Abstract

The first, second and third instars of Perkinsiella saccharicida were the only stages which transmitted Fiji disease virus to healthy Q70 plants after a 48 hour access feed on diseased plants. A key to distinguish the developmental stages of P.saccharicida was developed with the main distinguishing features being eye colour, and the shape, length and relationship, one to the other, of the fore and hind wing pads.
