The objective of this study was to ascertain the damage inflicted by the longhorn date palm borer Jebusaea hammerschmidti Reiche on date palm, Phoenix dactylifera L. Close observations were made on randomly selected date palms in infested plantation located in Al-Ahsa oasis, Kingdom of Saudi Arabia during the period from October 2011 to December 2015. Damage information was gathered from field observation and laboratory close examination of infested palm parts. Larvae (grubs) were responsible for most of the damage, which was mainly found on trunks and frond bases. The main external diagnostic symptoms of damage were adult exit holes and light brown gummy exidute from the trunk that eventually turned into dark brown to black. Less obvious symptoms were presence of brown powdery tissues (frass) around infested palm, withering of fronds, and crown decline. Characteristic undulating feeding galleries appeared in cross section of the trunk and fronds bases as internal symptoms. The impact of damage on palm longevity, utilization of wood, and management of this pest are discussed.
