农作物病虫害物理消杀机理与防控新产品研发进展OA

To address the national industrial demand for green prevention and control of crop pests and diseases in China,this paper focused on the research progress of the National Key R & D Program project,entitled"Mechanisms of Physical Pest Eradication and Development of Novel Control Products."Targeting on major pests and diseases infesting rice,vegetables,fruit trees and other crops,this review summarized the mechanisms of insect phototactic behavior,light-trapping rhythms and their underlying mechanisms and the mechanisms of male sterility inducted by X-ray irradiation in fruit flies.It systematically reviewed key technologies for precise and highly intelligent pest control using light/color trapping,along with a series of new physical control technologies and products.Furthermore,it summarized efficient and precise physical control technology models for major pests and diseases throughout the entire growth period of rice,citrus and protected vegetables(tomato,cucumber).These integrated technical solutions have been demonstrated and extended in major agricultural provinces and municipalities including Hunan,Fujian,Shandong and Beijing,covering a cumulative demonstration area of 86 700 hectare-times.In the demonstration areas,chemical pesticide application was reduced by more than 20％,generating significant economic,social and ecological benefits.The related research outcomes provided core technologies and practical products for the green control of major pests and diseases on rice,vegetables,fruit trees and other commercial crops in China,while also laying a foundation for the sustained innovation of physical control mechanisms and advanced control technologies and products.
