EVENTO
Pest biological control in a spatial prey-predator system with Allee effect in the control agent population
Tipo de evento: Exame de Qualificação
The release of a control agent - a natural enemy of the pest - is a commonly used strategy in pest biological control. The occurrence of Allee effects in the control agent is accounted for as one of the causes of pest biological control failure. Within this biological context, in the present work we assess: (i) how the intensity of the release of the pest enemy can be detrimental or advantageous to pest biological control goals; (ii) how the relative magnitude ofpest and agent diffusivities influence the outcomes of pest biological control. To this end we resort to numerical simulations of a spatial prey-predator model in an environment where pest and control agent species interact. We show that massive releases as well as extremely fast spreading agents can be detrimental to pest biological control.
