Abstract: | In this paper,we propose a two stage-structure model with density-dependent birth pulses and pulse harvesting.Using the stroboscopic map,we obtain an exact cycle of system,and obtain the threshold conditions for its stability. |

Keywords: | stage-structure pulse dynamics equilibrium bifurcation |
