Coded sampling forms used during studies on the life-system of the Swaine jack pine sawfly, Neodiprion swainei Middleton, are described. The forms permit the transfer of scientific data direct to punch-cards or magnetic tape. They are used for population sampling of various stages of the sawfly, as well as for sawfly dissection data, small mammal and bird census data, forest inventories, and climatological records.
