Extract

This paper describes the seasonal history and habits of the less important red pine cone insects, and presents notes on the predators, scavengers, and other insects that commonly inhabit infested cones. During 1950-1954, Eucosma monitorana Hein., Laspeyresia toreuta Groté, and Rubsaamenia sp. were rarely as abundant as the cone beetle, Conophthorus resinosae Hopk., (10) or Dioryctria spp. (11), although they contributed significantly to seed loss. Owing to the scarcity of these insects, some of the life history details remain incomplete.
