Abstract(s)
A limitação natural de pragas é um serviço de ecossistema que deve ser promovido nos
sistemas agrícolas, já que pode ser usada como alternativa, ou complementarmente, à aplicação
de pesticidas. Consiste no consumo das pragas pelos seus inimigos naturais e pode ser
promovida através do estabelecimento de componentes paisagísticas que forneçam, a estes
inimigos das pragas, alimento alternativo e refúgio, para além da aplicação de práticas agrícolas
sustentáveis. No entanto, o delineamento de uma estratégia eficaz de limitação natural de
pragas está dependente da caracterização detalhada dos comportamentos dos animais que
fazem parte dessa cadeia trófica, nomeadamente, das pragas e dos seus predadores, o que pode
ser feito através de simulações computacionais. Neste contexto, e no âmbito do projeto
OLIVESIM, estamos a construir um sistema de modelos para simular a biologia e o
comportamento de duas espécies de artrópodes (1) a mosca-da-azeitona, Bactrocera oleae
(Rossi), praga chave da oliveira, e (2) a aranha de solo, Haplodrassus rufipes (Lucas), um dos
potenciais predadores da praga, e as suas interações com a paisagem selecionada para realizar
este estudo, localizada na região de Trás-os-Montes (Mirandela, Portugal) e caracterizada
fundamentalmente por olival tradicional. Para isso, está a ser utilizado o sistema ALMaSS
(Animal, Landscape and Man Simulation System), que recebe inputs diários de variáveis
climáticas e também de ações de gestão agrícola, e que é calibrado com dados sobre abundância
quantitativa e qualitativa de animais. Neste simpósio focamo-nos nestes dois modelos,
mostrando também o estado atual deste trabalho.
Natural pest control is an ecosystem service that should be promoted in agricultural systems, as it can be used as an alternative or complementary to pesticide application. It consists in increasing the populations of natural pest enemies by establishing landscape components that provide them with alternative food and refuge, and by applying sustainable agricultural practices. However, the design of an effective strategy for natural pest control depends on the detailed characterization of the behaviour of animals that are part of this trophic chain, namely pests and their predators, which can be done through computational simulations. In this context, and in the scope of project OLIVESIM, we are building a system of models to simulate the biology and behaviours of two species (1) the olive fly, Bactrocera oleae (Rossi), key pest of the olive tree, and (2) a ground spider, Haplodrassus rufipes (Lucas), one of the potential predators of the pest, and their interactions with the landscape selected to carry out this study, located in the region of Trás-os-Montes (Mirandela, Portugal) and characterized primarily by traditional olive groves. For this, the ALMaSS (Animal, Landscape and Man Simulation System) system is being used, which receives daily inputs of climatic variables and agricultural management actions, and which is calibrated with data on quantitative and qualitative abundance of animals. In this symposium, we focus on the models for these two animal species, showing the current state of this work.
