Mendel, Z. 1988 The relation of bast scale and bark beetle outbreaks to management of pine plantations in Israel.. Integrated Control of Scolytid Bark Beetles / Proceedings of the IUFRO Working Party. Payne, T. L. & Saarenmaa, H., eds. :329-336.

Notes: Journal title continues: Vancouver, B. C., Canada: July 4, 1988. (XVII International Congress of Entomology Symposium.). Abstract: After silvicultural thinning, Orthotomicus erosus and Pityogenes calcaratus are among major insects (scolytids) attacking pine trees injured by the bast scale, Matsucoccus josephi; it is suggested that bark beetle outbreaks are the outcome of the temporary weakening of the trees due to extreme opening of the stand coinciding with high flight aggregation of these beetles; ecological pest management should focus on early thinning integrated with bast scale management.
