The Red Palm Weevil poses a very serious threat to Californias landscape plantings of ornamental palms if it were to become established here. A similar situation for SAPW-RRN may eventually develop in California. This damage provides entry for nematodes into palms and immature nematodes mature and reproduce inside palms. Females may also lay eggs into cracks or wounds on the trunk or the base of the fronds. Occasionally, meristematic tissue may occur near the base of the trunk where offshoots grow. RPW may establish readily in new areas because it has traveled with its food supply, or there are other ornamental or date palms nearby that it can infest once larvae finish developing and emerge as new adults that abandon their original host plant.
