By Andrew Porterfield The red palm weevil ( Rhynchophorus ferrugineus) is a common pest of palm trees in subtropical regions of the globe (and, for a brief time, in the United States ). Adult SAPW are strong fliers and have the potential to disperse naturally over long distances. In San Diego County, the weevil has shown a very strong preference for attacking Canary Island date palms; however, the palm species host list is growing, and we expect this pest to attack . The larval stage lasts 1 to 3 weeks. On the low end, replacing a small Saw Palmetto can cost $100 on average. A palm that is completely overrun may have no hope of survival, and will need to be removed, and destroyed, entirely. Preventive treatments with systemic insecticides may help; however curative treatments once symptoms are noticed are not effective. Systemic pesticides can be applied as soil drenches, soil injections, trunk sprays or paints, trunk injections, or as drenches applied to the crown. When adult weevils fly to another palm they may carry these hitch hiking nematodes on the outside of their bodies.

Riparian areas in California with susceptible palm species may provide good habitat for weevil populations to proliferate. Two different yearlong surveys by Brazilian scientists indicated that parasitism of SAPW larvae/pupae averaged 40% (range 18-50%) in one study and 51% (range 33-73%) in the second survey. College of Natural and Agricultural Sciences, Extension Specialist in biological control Applying systematic insecticides to the soil helps to eliminate the weevils in the egg stage. RPW adults are attracted by the pheromones and the plant material and fly into buckets. The best recourse is to cut down infested palms and destroy them before adults emerge from the tree. Large numbers of wilding Canary Islands date palms grow in unmanaged riparian areas and will provide abundant food for weevils. The efficacy of a local isolate of the entomopathogenic fungus Beauveria bassiana was tested against the red palm weevil (RPW) Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) larvae and adults by direct spraying of the fungus conidiospores on the targeted stages under laboratory conditions. Contact insecticides (i.e., pesticides that either kill on contact or leave a dry external residue that is lethal upon contact) can be applied to palm fronds or pruning wounds to kill adult weevils attracted to these substrates. This is a lethal pest of palms which can attack about 17 varieties of palm trees. The adults of the red palm weevil ( Rhynchophorus ferrugineus) are typical weevils: the head extends with a long thin rostrum that holds the antennae and tiny mandibles. Trunk injections or soil applications of systemic insecticides that move inside the palm poisoning weevil larvae and adults may also be effective. This collection in Laguna Beach represents the first timeR. ferrugineushas been found in the United States.

When you use insecticide as a palm weevil treatment, you must repeat the application two or three times every year. When they hatch, hundreds of larvae in the form of big grubs begin feeding at the top of the tree, in the palm's heart. An incision must be made to the middle of the trunk in order to reach the greatest number of conductive vessels or trachea. El-Lissy, O. Surveys forR. palmarumactivity in Tijuana Mexico in May 2016 revealed large numbers of dead Canary Islands date palms. The larvae (grub worms) then feed into the trunk causing severe vascular damage over time that eventually results in death of the infested palm. Palms are ubiquitous in the California landscape and they give urban and beach areas a distinct appearance that is strongly thought of as being southern Californian. The sex ratio is slightly biased towards females (1 male to about 1.2 females). Feeding larvae cause significant damage to the apical meristem and when severe, palm death can result.
