Fuzzy model of Drosophila mediopunctata population dynamics

Drosophila mediopunctata belongs to the tripunctata group, which is the second largest Neotropical group of the Drosophila genus, with 64 species described. This paper presents a p-fuzzy system to describe its population dynamics. An approach using fuzzy set theory was chosen to handle some problems of uncertainty in knowledge-based modeling. This model is based on population density, climatic variation and extractive activity. Simulations allow us to visualize the behavior of the population in different environments and seasons of the year. The results are consistent with previous studies showing that in preserved area the population exhibits oscillations with return to equilibrium while in altered area it can be extinguished after a certain time.
