Banana Leaf Wooly Worm
Eggs are laid on the reverse side of the leaves and 28 days Figure 2. Ceramidia larva 5-6 days.
As the larva grows, the band size increases. Damage is perpendicular to the central vein, finally perforating the leaf. The chrysalis is surrounded by numerous larva hairs, which protect against environmental conditions and predators. Chrysalises are found mostly along the central vein on the underside of the leaf, on the shoot and occasionally on the bunch.
The vast majority of the bananas currently grown and consumed were not conventionally bred but are selections made over probably thousands of years from naturally occurring hybrids. Cultivated bananas are very nearly sterile and as a consequence are not propagated from seed but rather through vegetative propagation, primarily suckers as well as more recently micropropagated or tissue cultured bananas. These factors, very old selections, near sterility and vegetative propagation, mean that these bananas have not been genetically improved either for resistance or improved quality and are becoming increasing in affected by serious pests and diseases.
