Resumo: In this work we propose a Coupled Map Lattice to study a predador-prey system where the prey is a pest and the predador is a biological control agent. We consider that the strategy of biological pest control is combined with a planned use of pesticides. That is, the chemical is sprayed only when the prey density is higher than the threshold control. Furthermore, application of chemical is made only in the patches of high pest infestation. In the absence of the chemical prey and predators move by diffusion. However, when the chemical is sprayed, the individuals have an escape behavior and they move from patches with high concentrations of the chemical to others with lower concentrations. The chemical, in turn, spreads by diffusion and by wind. The simulation results show that the initial distribution of predators can have great effect on the system dynamics and therefore the efficacy of biocontrol.

Consideramos que a estratégia de controle biológico da praga é combinada com o uso racional e planejado de pesticidas. Isto é, uma substância química nociva `a praga é utilizada apenas quando a densidade de presas atinge o limiar de controle. Além disso, a aplicação do agente químico é feita apenas nos sítios de alta infestação da praga. Na ausência do químico, presas e predadores se movimentam por difusão. No entanto, quando a substância é aplicada, os indivíduos têm um comportamento de fuga e se locomovem de sítios com altas concentrações do químico para outros com concentrações mais baixas. A substância química, por sua vez, se espalha por difusão e pelo vento. Os resultados de simulações mostram que a distribuição inicial de predadores pode ter grande efeito na dinâmica do sistema e, portanto, na eficácia do controle da praga.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de Ciências Naturais e ExatasPrograma de Pós-Graduação em MatemáticaUFSMBrasilMatemáticaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessPresa-predadorSubstância químicaRede de mapas acopladosDinâmica espaço-temporalControle biológicoDifusãoTaxiaPrey-predatorChemicalCoupled map latticSpatio-temporal dynamicsBiological controlDiffusionTaxisCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICAUm modelo para controle biológico de pragas associado ao uso de pesticidasA model for biological pest control associated with the use of pesticidesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisMistro, Diomar Cristinahttp://lattes.cnpq.br/5816121630218752Barros, Laécio Carvalho deGuedes, Jerson Vanderlei Carúshttp://lattes.cnpq.br/3507362275133401Frank, Adriane100100000008600901cd4da-552f-474a-ae2a-048c58d2b4ea1fccf13c-0bf2-4579-acdb-96ce452ae86a5d9cdd3f-800e-4754-991e-461aaeaa52610eabbb94-37a1-4707-bd14-5db96affd76breponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGMATEMATICA_2014_FRANK_ADRIANE.pdfDIS_PPGMATEMATICA_2014_FRANK_ADRIANE.pdfDissertaçãoapplication/pdf1012028http://repositorio.ufsm.br/bitstream/1/21647/1/DIS_PPGMATEMATICA_2014_FRANK_ADRIANE.pdfbfa7b4cac7158efa9130cbdebcd3d959MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
