    The Banana bunchy top virus (BBTV) is a circular single-stranded DNA virus ( nm in diameter) that causes Bunchy top in bananas. Although the disease was first reported in the late s, the virus itself, which was originally classified as a Luteovirus, was isolated in the late s and reassigned to the Nanoviridae family in the genus Babuvirus. cigar end rot, banana bunchy top virus disease, and post-harvest diseases. Banana thrips, nematodes and the banana weevil are among the most important pests of banana in most banana growing regions in banana weevil,(C. sordidus)is a major pest of bananas in all banana growing regions of Kenya (Kung’uet al., ).

      Field samples of banana plants affected by bunchy top disease from Hawaii, Indonesia and Tonga, but not unaffected controls, gave strong positive reactions when tested by enzyme-linked immunosorbent assay using Australian polyclonal and Australian and Taiwanese monoclonal antibodies specific for banana bunchy top virus (BBTV). Isometric virus-like particles, nm in diameter, were Cited by: Congo. The geographical distribution of the disease throughout the vast Congo basin, has, however, not been studied. Banana bunchy top virus (BBTV), a luteovirus, multiplies in the phloem and is transmitted by the aphid vector Pentalonia nigronervosa (Magee, ; Burns et al., ). Once established, it is extremely difficult to.

    Banana Industry Biosecurity Guideline Version: 1 Purpose banana bunchy top virus; and pest bananas. If a pest or disease is detected, such records may enable a parcel by parcel approach to be taken rather than whole-of-property controls being imposed. Brief introduction • Banana bunchy top disease (BBTD) is 1 of the most important disease of bananas in many producing regions • Virus can be spread by: – infected plant suckers – infected plant tissues used in banana micro- propagation – Aphid vectors, Pentalonia nigronervosa • Lots of misconceptions or inaccuracies regarding BBTD.
