•The most important way that banana bunchy top
disease (BBTD) spreads in Hawaii is by humans moving diseased planting material
between and among Hawaiian islands (according to the Hawaii Dept. of Agriculture).
•BBTD is also spread by a small insect, the banana aphid.The aphids pick up the virus while feeding
on diseased plants.These aphids are
infective; some can fly and spread the disease to healthy plants.
•The only known host for the banana bunchy top
virus (known as BBTV) is banana.
