A model for the development of the cabbage root fly ( Delia radicum L.) based on the extended Leslie model

An application of the extended Leslie model to predict the population dynamics of the cabbage root fly is given. This model couples several Leslie processes, one for each stage of the life cycle. The coupling is done via time-dependent transition probabilities reflecting the development status of th...

Description
Summary:An application of the extended Leslie model to predict the population dynamics of the cabbage root fly is given. This model couples several Leslie processes, one for each stage of the life cycle. The coupling is done via time-dependent transition probabilities reflecting the development status of the individuals which is described by the biological age. The model parameters were identified by experiments carried out. Comparing the simulation results with (i) laboratory experiments (controlled conditions) and (ii) field experiments (variable conditions) a good correspondence is observed. This simulation model can be used to analyze the effect of an insecticide application on the population dynamics of Delia radicum.
