叶螨的敏感性品系在抗性研究中对建立一个敏感度基线,准确监测抗性发展的动态十分重要。特别是在叶螨的抗性遗传的研究中,一个纯化的敏感性品系是不可缺少的必要条件。但是,由于化学防治水平不断提高,防治面积不断扩大,致使几乎无法采到纯的敏感品系。人们不得不从田间采得相对的敏感品系,经室内选育,使之纯化。最近,Keena等在美国加州研究二斑叶螨对克螨特的抗性
Sensitive strains of spider mites build a baseline of sensitivity in resistance studies and it is important to accurately monitor the dynamics of resistance development. Especially in the study of the resistance inheritance of spider mites, a purified sensitive strain is an indispensable requirement. However, as the level of chemical prevention and control continues to increase, the area of prevention and control continues to expand, making it almost impossible to obtain pure and sensitive strains. People have to obtain relatively sensitive strains from the field, and they are purified by indoor breeding. Recently, Keena et al. Studied the resistance of two-spotted spider mites to propargite in California, USA
