Abstract: In this paper, the main diseases and insect pests of jujube in hilly region of loess plateau in recent years were investigated. The meteorological conditions for the epidemic outbreak of 5 kinds of jujube’s diseases and insect pests in this region were summarized. The climate prediction models of jujube rust and jujube Carposina niponensis were established. The authors used the meteorological observation data of Jiaxian in nearly 34 years to test the models. The results showed that the occurrence probabilities of different levels of diseases and insect pests as indicated by the two prediction models were consistent with the actual situation; the numerical value distribution of typical disaster years coincided with the actual degree of the disaster. The two models can be used to predict the outbreak of two major diseases and insect pests in the loess plateau, and provide reference for the timely deployment and implementation of disaster prevention and mitigation.
