The Asian citrus psyllid (ACP) survival in the presence of contact insecticides may be through physiological adaptations or by behaviorally avoiding. Curiously, although the first alternative is the object of frequent attention, the second was often neglected, but both may lead to insecticide resistance. In this paper, we characterize the growth dynamics of ACP population using a novel impulsive differential equation model to account for the effect of physiological and behavioral resistance, and investigate the threshold conditions for the extinction of ACP population. Furthermore, we discuss the optimal switching methods for insecticides based on two different criteria. Our numerical result suggests that ignoring both resistances or behavioral resistance would underestimate the transmission risk of Huanglongbing, whereas only considering behavioral resistance leads to an overestimation.

亚洲柑橘木虱生理和行为抗性的建模与动力学

在接触杀虫剂存在下,亚洲柑橘木虱 (ACP) 的存活可能是通过生理适应或通过行为回避。奇怪的是,虽然第一个选择是经常关注的对象,第二个经常被忽视,但两者都可能导致杀虫剂抗药性。在本文中,我们使用一种新的脉冲微分方程模型来表征 ACP 种群的生长动态,以解释生理和行为阻力的影响,并研究 ACP 种群灭绝的阈值条件。此外,我们讨论了基于两个不同标准的杀虫剂的最佳转换方法。我们的数值结果表明,忽略抵抗或行为抵抗将低估黄龙病的传播风险,
