报告摘要：An eco-epidemiological lifecycle model incorporating interactions between the two hostsis formulated to explore the transmission mechanism. The basic and demographic reproduction numbers are developed to characterize the transmission dynamics. The study reveals that, under effects of the energy conservation, both population can coexist via a steady state or a cyclic oscillation bifurcated from a Hope bifurcation, and the disease becomes endemic simultaneously. Furthermore, we study how predation rates of foxes, voles control rates, and different voles control measures work. The findings suggest that improving the control rate of voles will reduce the risk of transmission, while the high predation rate of foxes may also lead to a lower transmission risk, which is different from the predictions of previous studies. The evaluation of the three control measures on voles implies that, when the fox’s predation rate is low (high), the chemical (integrated) control will be more effective.
