The development period of immature stages of the green apple aphid, Aphis pomi (De Geer) (Homoptera: Aphididae), at six constant temperature regimens (20, 24, 28, 30, 32, and 34C) was modeled to determine mathematical functions for simulating aphid development. Ten models (one linear and nine nonlinear) were used to describe the relationships between temperature and development rate of the different instars and stages of A. pomi (DeGeer) at constant temperatures. All models (except logistic and linear) provided accurate values for the optimum temperature for the Þrst-, second-, third-, and fourth-instar larvae and for total development. The results suggest that, amongfourmodels(HilbertandLogan,Lactin,Briere,andAnalytis)thatestimateallthreeparameters (tmin, topt, tmax), Lactin and Hilbert and Logan models gave the most suitable Þt of data.
