Growth Loss and Mortality of White Pine Nursery Stock Caused by Pine Bark Aphids After Field Planting
Outplantings of 2-0 white pine seedlings heavily infested with pine bark aphids were compared with outplantings of uninfested seedlings in a 1980-81 study. After two growing seasons, there was no statistically significant difference in mortality between heavily infested and uninfested seedlings. There was a significant difference in growth, however, with the uninfected seedlings averaging 11 percent greater growth than the infested seedlings.
