比较了8个观赏植物非洲菊品种对二斑叶螨的寄主适应性。这是通过确定来自每个品种的植物的叶盘上的叶螨的种群增加的内在速率rm来完成的。发现rm值存在较大差异，范围从品种Bianca的0.088/天到品种Sirtaki的0.242/天。这种rm的变化主要是由叶螨发育时间的差异引起的。
Eight cultivars of the ornamental crop Gerbera jamesonii Bolus (Asteraceae) were compared in host plant suitability for the two spotted spider mite Tetranychus urticae Koch (Acarina: Tetranychidae). This was done by determining the intrinsic rate of population increase, rm, of spider mites on leaf discs of plants from each of the cultivars. Large differences in rm values were found, ranging from 0.088/day on cultivar Bianca to 0.242/day on cultivar Sirtaki. This variation in rm was mainly caused by differences in developmental time of the spider mites.
