[[Banana bunchy top virus]] is a plant virus of the genus ''Babuvirus'', family ''Nanonviridae'' affecting ''Musa'' spp. (including banana, abaca, plantain and ornamental bananas) and ''Ensete'' spp. in the family ''Musaceae''.<ref>National Biological Information Infrastructure & IUCN/SSC Invasive Species Specialist Group.

Global Invasive Species Database. N.p., July 6, 2005.</ref> Banana bunchy top disease symptoms include dark green streaks of variable length in leaf veins, midribs and petioles. Leaves become short and stunted as the disease progresses, becoming 'bunched' at the apex of the plant. Infected plants may produce no fruit or the fruit bunch may not emerge from the pseudostem.<ref name="Thomas-2015">Thomas, J.E. (ed). 2015.

MusaLit, Bioversity International, Rome</ref> The virus is transmitted by the banana aphid ''[[Pentalonia nigronervosa]]'' and is widespread in Southeast Asia, Asia, the Philippines, Taiwan, Oceania and parts of Africa. There is no cure, but it can be effectively controlled by the eradication of diseased plants and the use of virus-free planting material.<ref>{{cite web |last1=Thomas |first1=J.E. |last2=Iskra-Caruana |first2=M-L. |first3=D.R. |last3=Jones |year=1994 |title=''Musa'' Disease Fact Sheet N° 4.
