Pheromone traps make it possible to detect very low density pest populations that would otherwise be almost impossible to find. SAPW cannot reproduce on these fruit. Host plant resistance can reduce the ability of Red Palm Weevil to damage palms because the weevil is unable to effectively exploit these hosts. We also offer care, nourishment, and tree preservation treatment to safeguard palm trees from such infestation in the future. College of Natural and Agricultural Sciences. Dr. Daniel Herms, Vice President of Research & Development at Davey, shares recent climate change data and projections. To track the spread of SAPW we need the help of community scientists, interested and concerned members of the public, who are willing to take time to report SAPW infestations via the web.

Faleiro Adult weevils are strong fliers and can fly up to 900m (~900 yards) at a time and they can move up to 7 km (~4.3 miles) in 3-5 days. As the infestation progresses, damaged palm material inside the palm will start fermenting and it acquires a characteristic odor. Insecticides are probably the most common control tool used against Red Palm Weevil, and can applied in a variety of ways for RPW suppression including applications as dusts, liquid sprays. An incision must be made to the middle of the trunk in order to reach the greatest number of conductive vessels or trachea.

Immature nematodes can apparently infest weevil larvae and remain in an immature stage until larvae pupate. From wetlands and streams to stormwater management and tree inventories, we offer turn-key solutions for clients nationwide. The Red Palm Weevil (RPW) (or Rhynchophorus ferrugineus) is a major transboundary pest that originated in South Asia and is rapidly spreading around the world. High levels of feeding damage to the apical meristem can result in palm death as frond and trunk growth originates from this region. Non Native Invasive Species California - where? Red Palm Weevil larvae feed within the apical growing point of the palms creating extensive damage to palm tissues and weakening the structure of the palm trunk.

Trunk injections or soil applications of systemic insecticides that move inside the palm poisoning weevil larvae and adults may also be effective. Trunk injection of IMA-jet (Imidacloprid) will give both preventative and curative control providing there has not been extensive feeding damage to the palm. A palm that is completely overrun may have no hope of survival, and will need to be removed, and destroyed, entirely. Any stress factors such as drought, excessive moisture, cold damage, lightning strikes, fire and nutrient deficiencies can cause palms to be at risk. In commercial groves, mass trappings with aggregation pheromones have also been used, as well as chipping and burning infested material so the pest doesnt continue spreading.
