Conservation Strategy for Palm Groves: Optimal Chemical Control Model for Red Palm Weevil, Rhynchophorus ferrugineus

Rhynchophorus ferrugineus (Olivier, 1790) is an invasive pest species that constitutes one of the most important problems around Mediterranean region and has been responsible for loss over 100,000 palm trees with estimated annual cost EUR several hundred million since its introduction into Europe. Methodological approaches conservation ecology, such as multidisciplinary modelling, also apply in management cultural landscapes concerning ornamental plants, area. In this paper, we propose a dynamic model control red weevil, contributing way to sustainability existing landscape. The primary data set collected sample from density-time function two-cohort population. This suggests bimodal analytic description. If, set, calculate accumulated (the integral function), it displays double sigmoid (with two inflections). A good candidate analytical description latter sum logistic functions. As process, two-dimensional system differential equations can be obtained, where solution’s second component provides original Since waves appear all three cycle stages, reasoning applies subpopulations larvae, pupae adults. fitting always performed using SimFit package. On basis, mathematical proposed, which sufficiently versatile help other geographical areas.
