I am analysing results of my study related to development rates of Helicoverpa armigera w.r.t different favourable temperature regimes varying from 18.75 to 24.17 degree celsius to find out optimum, minimum and maximum threshold temperatures . I am facing problem w.r.t feeding starting values of parametres for the models suggested by Briere (1999) , Lactin (1995), etc.
