abstract = {<p style="text-align: justify;">By combining geometric singular perturbation theory (GSPT) with
qualitative method, this paper analyzes the phenomenon of successive canard
explosions in a singularly perturbed Spruce-Budworm model with Holling-II
functional response. We select suitable parameters such that the critical curve
is $S$-shaped, and the full model only admits a unique equilibrium. Then, under
the variation of the breaking parameter, it is found that a canard explosion
followed by an inverse canard explosion successively occurs in this model. That
is, a relaxation oscillation arises via the first canard explosion, which persists for a large interval of parameter until it vanishes via the so-called inverse
canard explosion. All these theoretical predictions are verified by numerical
simulations.</p>},
