In this paper, according to the biological characteristics of B. gobica, it was divided into psyllid nymphs and adults, considering the chemical control of B. gobica combined with biological control, according to the resistance of psyllid nymphs and adults to pesticides as well as the predatory role of the dominant natural enemies on it, and we established a model of integrated control of B. gobica combined with the resistance to pesticides and the structure of stage. We investigated the dynamical properties of the model developed, theoretically proved the consistent boundedness of the system, and demonstrated sufficient conditions for the existence and global attractiveness of the periodic extinction solution of B. gobica. The effect of resistance development on B. gobica population density was discussed numerically, and the integrated B. gobica management strategy was compared with a single control strategy (chemical or biological), the effect of the number of pesticide sprays on the development of resistance to B. gobica was investigated, as well as the timing of pesticide switching according to the threshold theory, and, finally, the effect of the rest of the key parameters on the extinction threshold of B. gobica was illustrated by the contour plots as well as by sensitivity analyses. The results showed that shortening the release of natural enemies and the pulse period of spraying, controlling the intrinsic growth rate of nymphs, selecting pesticides with lower killing effect on natural enemies, controlling the killing rate of pesticides on natural enemies, and increasing the number of natural enemies released can be of great help to the management of B. gobica.
