Extract
During 1958 a general infestation of Pineus coloradensis (Gillette) was observed on red or Norway pine, Pinus resinosa Ait. This insect is widely distributed throughout western United States where it attacks a number of pines. The Annand collection has a slide with specimens of P. coloradensis (Gillette) taken from red pine on the Universitv of California campus dated February 10, 1925. However, there are few reports of any Pineus species attacking red pine in its natural range from the region of the Great Lakes to the Atlantic coast. Shenefelt and Benjamin (1955) have reported the white pine bark aphid or a closely related form on red pines in Wisconsin. Bean and Godwin (1955) also mentioned the presence of an unidentified species of Pineus on red pine.
