THRESHOLD TEMPERATURE FOR SPRUCE BUDWORM PUPAL DEVELOPMENT (LEPIDOPTERA: TORTRICIDAE)
Published online by Cambridge University Press: 31 May 2012
Extract
A frequently used method for determining the threshold temperature for insect development is based on the expression for the hyperbola and its reciprocal (Bean 1961). This method has certain disadvantages, the major one being that the developmental velocity curve is sigmoid and the selection of a linear portion of this curve has a subjective element (Morris and Fulton 1970).
