Nonlinear Modeling Treatments

Hi,

I'm trying to compare the effect of temperature on developmental rate using various nonlinear models in SAS. The temperatures range 10-35 degrees C.

At the 10 and 35 degree treatments I get no development. I want to know if I should include these 0 development data points when fitting my nonlinear models. Looking at the literature it seems to vary whether authors use these 0 data points when constructing the curves or to exclude them and let the models fit it. What is the accepted practice?
