报告题目:Mathematical models for citrus Huanglongbingand chemical and biological control（柑橘黄龙病及其化学生物控制的数学模型）
Abstract: Huanglongbing (HLB) is one of the most common widespread vector-borne transmission diseases through psyllid, which is called a kind of cancer of plant disease. In recent years, biologists are focused on the role of cross protection strategy to control the spread of HLB. In this talk, according to transmission mechanism of HLB, a deterministic model with cross protection is introduced. A threshold value $R_0$ is established to measure whether or not the disease is uniformly persistent. The existence of a backward bifurcation presents a further sub-threshold condition beyond $R_0$ for the spread of the disease. We also discuss the effects of cross protection and removing infected trees in spreading the disease. Numerical simulations suggest that cross protection is a promotion control measure, and replanting trees is bad for HLB control.
