This function has the following characteristics: (1) if temperature is equal to or below the lower base temperature (Tb), or equal to or higher than the upper base temperature (TB), the function is zero, implying that no development occurs under these conditions; (2) the beta function equals to one when the temperature is equal to the optimum temperature (Topt), and has a value below one but higher than zero in the intermediate conditions.
Expected germination time courses were obtained from the equation [t.sub.G] = (T-Tb)/[[theta].sub.G], where: [t.sub.G] is the expected time (in days) to primary root emergence of percentage G; T is the average daily temperature estimated from the arithmetic mean of the maximum and minimum daily temperatures recorded both from local (Test site) and CEAPLA; Tb is the base temperature (estimated from Test 1) and; [[theta].sub.G] is the thermal time (in degree-days) required to germination of percentage G, also estimated from Test 1.
Since the data on developmental threshold temperature (base temperature) is not available for this pest, the method of Arnold (1959) was used, in which DD to first emergence are computed for a number of base temperatures (0, 2, 4, 6, 7, 8 and 10C) for different years.

The base temperature used in energy modeling methods can be interpreted as the "balance temperature," i.e., the outside temperature at which the building's internal heat generation offsets its losses.
