Nortbem jack pine populations were more susceptible to tbe eastern pine sboot borer (King, 1971 Jeffers, 1978 Hodson et al, 1982, 1986). Jeffers (1978) observed that incidence was correlated with length of the terminal shoot during the period of borer oviposition in May, with longest terminals having highest incidence and shortest terminals the lowest. Source variabibty was also described for resistance to the northern pitch twig moth, but was not related to latitude (Hodson et al, 1982, 1986).
