In the Mediterranean area, a major concern is the conservation of palm tree landscapes against the red palm weevil, Rhynchophorus ferrugineus (Olivier, 1790). The methodological approach of conservation ecology, such as multidisciplinary modelling also applies in the management of cultural landscapes concerning ornamental plants like palm trees of the area. In the paper we propose a dynamic model for the control of the red palm weevil, contributing in this way to the sustainability of an existing cultural landscape. The primary data set collected is a sample from the density-time function of a two-cohort pest population. This data set suggests a bimodal analytic description. If, from this data set, we calculate a sample from the accumulated density-time function (the integral of the density-time function), it displays a double sigmoid function (with two inflections). A good candidate for the analytical description of the latter is the sum of two logistic functions. As for the dynamic ...
