Abstract In June 2018, Fr. Diener presented some results on Dynamic of a Population of Spurce Budworms and she received interesting questions on what would happen if the “external” parameter would change slowly (depending on the dynamic of the forest or of birds who contribute to fight against the pest). We will present such a three-dimensional slow-fast model that, under some conditions, exhibit hysteric cyclic behaviour.
