Abstract:Feeding behavior of two instars of the spruce budworm, Choristoneura Fumiferana (Clemens), was shldied with sucrose and white spruce, Picea glauca (Moench) Voss, sugar extracts. Feeding preferences were similar for third and sixth instars. Relative feeding rates on plant sugar extracts were higher for third than for sixth instars. When sugar fractions from early- and late-growth current-year foliage were used, relative feeding rates were greatest for third and sixth instars, respectively.
