我国天敌昆虫资源发掘利用与新产品创制研究进展OA

Promoting green management of crop diseases and insect pests is a major strategic priority for safeguarding national food security and ecological security and advancing high-quality agricultural development.As natural guardians of agricultural ecosystems,natural enemy insects offer a key route to sustainable pest management through resource exploration and product innovation.This review systematically summarizes recent research and application advances in the exploration and utilization of natural enemy insect resources and the development of new products in China since implementation of the special program"Research,Development and Demonstration of Integrated Technologies for the Management of Major Diseases and Insect Pests"under the National Key R&D Program of China in 2023.In resource exploration,a nationwide survey network has enabled the discovery and identification of new parasitoid and predatory natural enemy resources.Functional response evaluation,omics technologies and studies of molecular interaction mechanisms have deepened understanding of their pest-suppression potential,foraging and host location,and coevolution with hosts.In commercial production,key bottlenecks in mass rearing and quality control have been overcome through the optimization of alternative hosts,artificial diet formulation,diapause regulation and adaptation to environmental stress.These advances have established systems of production processes and equipment for diverse natural enemies,including predatory bugs,Trichogramma parasitoids and predatory mites.In practical application,whole-process green pest management approaches have been developed by integrating precise releases of natural enemy insects,banker plant systems,ecological regulation and selective pesticides.Large-scale demonstration and adoption in major rice-producing regions and areas of protected fruit and vegetable cultivation have substantially improved pest suppression and management efficiency while reducing chemical pesticide use.Future priorities include further exploration and conservation of indigenous natural enemy resources,the development of intelligent and standardized production equipment,genetic improvement of natural enemy insects using cutting-edge technologies such as gene editing,and research on ecosystem services supported by the integration of multiple technologies under climate change.These efforts will advance biological control and strengthen scientific and technological self-reliance in plant protection in China,while providing essential scientific and technological support for climate-smart,biodiversity-friendly modern agriculture.
