Conophthorus coniperda
white pine cone beetle
Conophthorus coniperda, the white pine cone beetle, is a scolytine weevil that develops entirely within the cones of eastern white pine (Pinus strobus). Adults emerge in spring to attack new cones, and larvae feed on cone tissues and seeds, often killing the cone. The species is typically univoltine, though some individuals require two years to complete development. It is a significant economic pest in white pine seed orchards due to seed destruction.
