DescriptionThe white-pine cone beetle (Conophthoras coniperda ( Schwarz ) ) can cause extensive damage to cones of eastern white pine (Pinus strobus L.) and can severely hamper natural reproduction of this species (Graber 1964). This insect also will be a potential pest of seed orchards for the production of genetically superior seed if and when such orchards are established. It may be assumed that in certain areas, and for certain purposes, these seed orchards will contain white pine species that are exotic to the Northeast, or are hybrids of P. strobus and exotic species. Knowledge about the relative vulnerability of non-native species to this insect is extremely limited.
