The other solution is to grow pines under some shade. Shade means lower temperatures, and insects develop slower under cooler conditions. A lesser insect pest of white pine is the gypsy moth. The gypsy moth defoliates trees, and prefers Oaks and Aspens. Older larvae will eat pine needles while the young larvae will not.
Animal control is the next most important problem to growing healthy white pine.
This is of course only a threat when the trees are young, because after a few years the deer cannot reach the lowest branches.
