Mayetiola eggs on Red cedar conelet Kaltenbachiola pupae in spruce cone axis
Put three fine mesh bags on each parent tree. Inoculated with budworm eggs
Measured Extent of feeding, Survival to pupa
Found wide range of clonal variation in feeding performance Survival was worst in non-preferred clones
