PALMS - A PART OF OUR HERITAGE
Palms, sand and beautyIn the past two years sales of coconut water have more than doubled to $60 Million (Fortune Magazine June 14)
Facing several threats –lethal yellowing, coconut mite, and now weevils

ORIGIN AND DISTRIBUTION
Native to South and Southeast Asiawhere it is a key pest of coconut
Moved to the Middle East and Africain the 1980s where it is a major pest of date palms
By the early 1990s it had spread throughout the Mediterranean to Spain
In the 2000 reported in Australia

DETECTION OF EARLY STAGE INFESTATIONS
The ability to detect early stage infestations is critical for IPMRecognizing damage symptomsSome suggested tools:
Acoustic detection:Variety of acoustic equipment
Sniffer dogs

IPM: SANITATIONEradication of severely infested palms Cutting fronds if required at a distance of 1m from the frond baseMethods for trunk and frond disposal are critical
TimelyBurningChopping and Burying at appropriate depth)
Chipping/grinding
