环境因素对水稻品种抗褐飞虱的影响研究概况

A review on factors affecting resistance of rice varieties to the rice brown planthopper

褐飞虱是东南亚、东亚水稻产区的重要害虫。栽培丰产的抗虫水稻品种是防治该虫经济有效的措施之一,由于作物抗虫性是在一定的环境条件下寄主与昆虫相互作用的表现,不同环境条件对作物抗虫性有影响。本文从气候因素、土壤肥力因素、生物因素、人为因素、抗虫品种和褐飞虱及不同因素综合作用等几方面概述了环境因素对水稻品种抗褐飞虱的影响,并提出了有待于今后进一步研究的问题。

The brown planthopper, Nilaparvata lugens Stal, is one of the most harmful insects on rice in Southeast Asia and East Asia. Planting high-yield and multiresistance rice varieties is an economical and effective measure for preventing and controlling the brown planthopper. Because the resistance of crops to insects is the result of interaction between crops and pests under certain environmental conditions, it will be affected by different environmental factors. This paper summarizes the effects of environmental factors, including climatic factor, soil fertility factor, biological factor, human factor, insect resistant varieties and the rice brown planthopper, and the composite factors affecting the resistance of rice varieties to brown planthopper. The problems that must be further studied in the future are also put forward and summarized.
