Extract

The meteorological program of the Sault Ste. Marie Forest Insect Laborarory was inauguraced during 1946, with the establishment of stations at Sault Ste. Marie and Black Sturgeon Lake, for the study of the spruce budworm,Choristoneura fumiferana (Clem.) (vide Freeman, 1947) as its first subject. During 1946 and 1947, joint field and laboratory studies have been concerned primarily with the effects of evaporation, temperature, light and air currents upon the behaviour and activity of the insect. Recently, the work has been extended to include studies of the stages which can be dispersed by air currents and studies of certain aspects of the microclimates of the habitat.
