Palms in the advanced stages of attack and mortality have a flattened top, and as the remaining halo of fronds that ring the top of the trunk dry down, the palm looks like a giant brown umbrella or mushroom. Ornamental palm tree sales are estimated at $70 million per year in California, and $127 million in Florida. Feeding in this region can lead to trunk collapse and palm death. Riparian areas in California with susceptible palm species may provide good habitat for weevil populations to proliferate. cide treatment programs are implemented or restrictions on the movement of host plant materials are established. Working unseen and deep inside the palm trunk, the weevil larvae tunnel and feed, eventually killing the palm. Trap efficacy is maximized if traps are placed in areas with partial or full shade. When palm weevils infest a tree, it shows signs of disease, such as brown, drooping fronds. (C)Adult SAPW next to a US quarter (top) and a US penny (bottom). "Once the top of the tree is damaged severely, it will drop and it cannot recover," Hoddle said. Anyone with a sago palm needs to know how to control palm weevils. Systemic pesticides (mainly neonicotinoids) are translocated within the palm and accumulate in the meristematic tissue where weevil larvae feed.

Insecticidal treatment of trees infested with the palmetto weevil is difficult owing to problems with detecting a weevil infestation before lethal damage is done to the crown. Nematodes may reside inside tracheal sacs, part of the weevils tube-like breathing system, from where they can move to the ovipositor (i.e., egg laying tube) of female weevils. Bucket traps can be suspended above the ground or partially buried. 2017 Arborjet, Inc. It is likely that San Diego County was invaded by weevils that originated from Tijuana Mexico,where infestations and dead palms had been detected earlier (December 2010). Additional information and photos of RRN and red ring disease are available. Several natural enemies of SAPW are known, but one group of natural enemies, parasitic flies, in the genusBillaea(formerlyParatheresia) (Diptera: Tachinidae), appear to be exceptionally promising candidates for use in a classical biological control program targeting SAPW in California. Eggs are laid in these holes, they are relatively large, and female weevils can probably lay a hundred eggs or more over the course of a life time. Are Weevils Destroying Palm Trees in San Diego? Another problem South American palm weevil can cause is red ring disease since this pest vectors a nematode that transmits the disease.

From trimming and pruning, to tree removal, to disease and pest control - you will always get outstanding service and exceptional treatment. The entire life cycle, egg to adult, can take 45 to 139 days. These fermentation odors (especially when coupled with aggregation pheromone) from feeding and other types of damage (e.g., pruning wounds or pathogen infections) attract weevils to palms which intensifies attacks. 11Report an Infested Palm. Rhynchophorus palmarum (South American palm weevil); larvae have no legs, initially 3-4 mm long, may reach 5-6 cm. 7Chemical Control Red Palm Weevil is attacked by a variety of different natural enemies including parasites and small predators that attack weevil eggs, while bacteria, fungi, and nematodes can kill weevil larvae. To protect against infestation, palms should be sprayed with chemical insecticides (clorpirifos 48%, imidacloprid) or nematodes (or a combination of the two) as a preventative measure. The South American palm weevil and red ring nematode (should it establish in California) have the potential to cause significant damage to native and non-native palms in California. These areas are surrounded by densely populated urban areas that have an impressive number and species variety of palms. The list of suceptible palms is a little longer for south Florida. Once the damage is noticed, the palm is most likely beyond salvage. You can also wrap the trunk and foliage of palms for winter palm tree protection. The prepupal larva molts inside the cocoon and develops wing buds. If detecting low levels of palm weevil activity in the general vicinity is the goal of the monitoring program, traps should be deployed outside (perhaps > 0.5 mile away) of the immediate area of concern.
