粉虱和蓟马类害虫是我国经济作物上的主要害虫,为害呈逐年加重趋势,其抗药性也是生产中的主要问题。抗药性水平监测是害虫抗性早期预警和治理的基础,了解害虫抗药性水平须建立一套准确易于操作的监测方法。分别针对粉虱成虫和蓟马的琼脂保湿浸叶法和叶管药膜法的最大特点是快速、便于操作,接虫前的准备工作可以提前1~2 d完成,可监测当代试虫的抗性水平,结果更接近于田间实际,适合在粉虱和蓟马抗性监测中推广使用。
Whitefly and thrips pests are the major pests on economic crops in our country. The harm is increasing year by year, and its resistance is also the main problem in production. Resistance level monitoring is the basis for early warning and management of pest resistance. Understanding the level of pest resistance requires the establishment of an accurate and easy-to-use monitoring methodology. The most important feature of the agar moisturizing and leaf sheath membrane methods against adults and thrips of whitefly, respectively, is rapid and easy to operate. The preparation before picking can be completed 1-2 days in advance and the resistance of contemporary pests can be monitored Sexual level, the result is more close to the actual field, suitable for the promotion of whitefly and thrips resistance monitoring.
