The biology and behavior of Orthotomicus erosus (Wollaston) (Coleoptera: Scolytidae) in the subcortical zone of pine in Israel are described. The pest attacks and develops in various Pinus species and uses them, or species of Cupressus, for maturation feeding. In Israel O. erosus is clearly bigamous. Rates of development of various stages at different constant temperatures were measured and discussed. The accelerated development of O. erosus at high temperatures demonstrates its good adaptation to the hot weather prevailing in Israel. © 1982 Springer Science + Business Media B.V.
