The purpose of this study is to understand the composition and distribution of alien invasive insects in The Nanling Mountain Priority Area Guangxi,to provide technical support for Monitoring and warning sys-tem and risk management,it is essential to conduct a systematic investigation and establish a risk assessment system to assess the invasive risks of invasive insects.The alien invasive insects in The Nanling Mountain Re-gion of Guangxi From September 2021 to August 2023,an investigation was arried out 11 systematic in-depth surveys of alien invasive insects in the region for a total of 85 days,and recorded that the alien invasive insects in the region belong to 6 orders and 10 families,a total of 13 species:Bemisia tabaci,Trialeurodes vaporario-rum,Oracella acuta,Blattella germanica,Periplaneta americana,Acanthoscelides obtectus,Sitophilus oryzae,Lissorhoptrus oryzophilus,Bactrocera cucuribitae,Bactrocera dorsalis,Solenopsis invicta,Hyphantria cunea,Spodoptera frugiperda.7 species originated from the Americasand 3 pecies originated from the Africa.Among the 13 alien invasive insects,11 species were obviously invasive with 7 species being high-risk invaders and 4 species being medium-risk invaders.7 species such as Blattella germanica,Periplaneta americana,Solenopsis invicta are the dominant invasive species,the number of alien invasive insect species outside the nature reserve exceeded those within them.The habitats in The Nanling Mountain Region of Guangxi favorable to tropical and subtropical invasive insects.Relevant laws and regulations should be formulated and new control technologies should be created to strengthen the management and control of alien invasive insects in the region.
