Abstract - The fruit tree shot hole borer has become recently of economic importance in Jordan. This work is the first study on this pest in Jordan. Field and laboratory tests were conducted to give ecological and biological informations for better control. The borer attacked six tested species including cherry-, plum-, almond-, peach-, apricot- and apple tree. More tunnels and heavier saw-dust were significantly produced in cherry-, plum-, peach- and almond- than apricot- and apple tree. More survived adults were significantly recorded on cherry-tree than any other tested plant species. It seems that the branches of all deciduous trees emit odor in the surrounding environment attracting adults, but in variable degree. Removed and weakened branches carried a significantly higher number of saw-dust like infestations than live branches. Some aspects of the life history and habits are described in details. Several conclusions are recommended to improve the control of this scolytid.
