Abstract：The population density of Citrus psyllids exhibits a significant positive correlation with the epidemic intensity of Huanglongbing(Huanglongbing disease).As a destructive pest,Huanglongbing can cause yellowing of citrus leaves,fruit malformation and shrinkage,quality deterioration,and in severe cases,tree decline or even complete plant death,posing a serious threat to the citrus industry.Precise monitoring of psyllid population dynamics and implementation of scientific control measures are crucial for interrupting the spread of Huanglongbing.Based on this,this study conducted systematic monitoring of C.psyllid population dynamics from 2024 to 2025 in the main citrus production areas of Chenzhou city,Hunan province(covering Yongxing county,Yizhang county,Guiyang county,and Beihu district),through fixed-point surveys,yellow trap collection,and meteorological data collection.The study analyzed the spatiotemporal distribution patterns and meteorological influencing factors of C.psyllid,and proposed comprehensive control technologies tailored to local conditions.This paper provided practical evidence for scientific monitoring and efficient management of C.psyllid,which holded positive significance for enhancing the comprehensive control level of Huanglongbing,reducing chemical pesticide usage,and promoting the green and sustainable development of the citrus industry.
