We use computer programme of Maia et al. (2000) in the software package Lifetable SAS to evaluate treatments (foods) on one predator (coccinellidae) at the same temperature. However, this programme use just one age (egg-adult at one temperature), and now we evaluate one specie's life table on different tempreatures. Exist some SAS programme to do this?
Thanks
