Promoting Major Pests Green Prevention And Control Based On Multi-omics Technology
Through application of multi-omics technologies,the Ecological Genomics Center focuses on studying the genomic basis of harmfulness and invasiveness of major agriculture pests and pathogens,and the molec- ular mechanism of pest-host and pathogen-host interactions.Research at the Center is designed to identify molecular targets for sustainable pest and pathogen control,as well as inheritable resistance-related genetic elements in crop genomes.Through these efforts,the Center aims to estab- lish integrative and eco-friendly warning-monitoring-management systems.and to develop sustainable pest management methods and products to support national food security and sustainable development of the Guangdong-Hong Kong-Macao Greater Bay Area.

农业害虫嗅觉编码的神经和分子机理研究
系统研究了重大农业害虫棉铃虫的气味受体基因家族的功能，首次全面解析了棉铃虫识别寄主挥发物的嗅觉功能图谱；揭示了鳞翅目昆虫通过嗅觉与被子植物协同进化的新机制，为发展对多种鳞翅目害虫高效的绿色防控技术提供了新的分子靶标。该成果作为封面文章发表在生物进化权威期刊《MolecularBiology and Evolution》上。
This study systematically reported the global function of the odorant receptor (OR)family in the major agricultural pest cotton bollworm Helicoverpa armigera,and for the first time generated the global function map of the odorant receptors for coding host-plant volatiles.On this basis,further reveal a new mechanism of olfactory mediated co-evolution between lepidopteran insects and angiosperms.and also provides new molec- ular targets for the development of efficient and eco-friendly technology against various lepidopteran pests. This work was selected for the cover story published on the journal of Molecular Biology and Evolution.
