宁夏苜蓿主要害虫发生规律与综合防治研究概况OA

Medicago sativa,a high-quality leguminous forage widely cultivated in the northwest region,is currently facing increasingly severe pest threats due to large-scale cultivation.Based on a systematic review of the occurrence and damage regularities of the main pests[including Thysanoptera,Aphidoidea,Miridae,Loxostege sticticalis Linnaeus,Helicoverpa armigera(Hübner),and Spodoptera exigua(Hübner)]in the Medicago sativa planting areas of Ningxia,the existing comprehensive control technologies and strategies are summarized and reviewed from four aspects:agricultural control,physical and chemical attract-and-kill methods,chemical control,and biological control.It is further indicated that biological control and ecological regulation are expected to become the core technological support for the future green Medicago sativa industry.It aims to provide systematic theoretical basis for the sustainable control of Medicago sativa pests and contribute to the sustained healthy development of the forage industry in Ningxia and across the country.
