Perkinsiella saccharicida

Biology

The sugarcane delphacid, Perkinsiella saccharicida, is a sugarcane pest native to Oceania and was first reported in Louisiana in 1994 (White et al. 1995). Females deposit eggs into leaf tissue. Eggs are laid in clusters on either side of the leaf, mainly along the midrib, leaf sheaths and stalk internodes. A female can lay up to 300 eggs during her normal 30-day life span. The incubation period varies from 2-3 weeks. The newly hatched nymph is pale, wingless, and starts feeding shortly after hatching. The nymphal period has 5 instars and lasts approximately 32 days. The first, second and third instars are important disease vectors (Francki et al. 1986).

Damage
The insect is not considered an economic threat in Louisiana. Damage is mainly caused by the adults and nymphs feeding on the sap of sugarcane plants. The feeding and laceration of leaves during oviposition cause yellowing and/or reddening and desiccation of the leaves. Additional damage results from impaired photosynthesis caused by growth of a sooty mold on honeydew excreted by the insects.
