The 1965 aerial spraying operations was the sixth in the current series to protect the forests in central New Brunswick from the spruce budworm. It was also the thirteenth operation since the commencement of large scale aerial spraying operations in the Province in 1952. Increased emphasis was given to experimental studies this year in addition to the usual operational program. A preliminary assessment of the effectiveness of the operational program is provided herein together with a forecast of budworm populations for 1966. Analyses of the data collected in 1965 are still in progress; conclusions drawn in this statement are there fore based on partial analysis of data only and may be subject to change.
