Uma Abordagem Fuzzy para um Modelo Presa-predador Acoplado ao Parasitismo

Abstract: Resumo. Nesse trabalho utilizamos sistemas baseados em regras fuzzy para elaborar um modelo do tipo presa-predador acoplado ao parasitismo para estudar a interaçao entre pulgões (presa/hospedeiro), joaninhas (predador) e um afídideo (parasitóide) na citricultura, onde pulgões são considerados agentes transmissores da Morte Súbita dos Citros. Simulações são realizadas e analisadas por gráficos de populações de presas, potencialidade dos predadores e população de parasitóides, bem como um espaço de fase obtido p… Show more

“…In our study the number of the natural enemies increased from 1 year to the next, which probably contributed to reducing the number of herbivores in two sites (CDS_1 and CS_1). According to Parra 2000 andPeixoto et al 2007 natural enemies are the main cause of insect mortality in agroecosystems.…”
