Long-horned beetles (Cerambycidae) may become severe pests when they encounter tree species suitable for their colonization and development. Susceptible host trees may display a genetic mismatch or be subjected to physiological weakness, and therefore lack the required defense systems needed to face the beetles' attack. Approximately 130 species of cerambycids are known in Israel, and as expected, only a minority among them are considered severe pests of healthy trees. Herein, we review some indigenous species that have become harmful: the duke beetle Cerambyx dux, the great capricorn beetle C. cerdo, the grape wood borer C. Chlorophorus varius, the mango branch borer Niphona picticornis and the sycamore borer Rhaesus serricollis. The five aggressive invasive long-horned beetle species identified in Israel, are also briefly discussed: the mango stem borer Batocera rufomaculata, two eucalyptus borers Phoracantha semipuncatata and P. recurva, the lebbek borer Xystrocera globosa, and the black pine sawyer beetle Monochamus galloprovincialis, known as a vector for the pine pathogenic nematode Bursaphelenchus xylophilus. Potential damage of the two Asian long-horned beetles, Anoplophora glabripennis and A. chinensis in Israel is discussed. Both these species have already become established in the East Mediterranean and may invade northern Israel in the near future. We present in brief, the direct and indirect effects of climate change on the performance of long-horned beetles as tree pests. Development of management tools to cope with the emerging problem of the long-horned beetle focused on three fields of activity. 1) Evaluating ten commercial insecticide formulations to prevent tree colonization by long-horned beetles, with an emphasis on environmentally friendly compounds; 2) evaluating the efficacy of specifically designated seismic sensors to detect tree colonization by larvae of long-horned beetles; 3) establishing a network of traps baited with commercial lures to identify the occurrences of the Asian long-horned beetles and the black pine sawyer beetle in Israel.
