- Abstract
Based on resistance selection, the life tables of abamectin-resistant (AbR), fenpropathrin-resistant (FeR), and susceptible (S) strains of Tetranychus cinnabarinus at 15 °C, 20 °C, 25 °C, 28 °C, 31 °C, 34 °C, and 36 °C were constructed, and the development duration, fertility, and intrinsic rate of increase (rm) of the strains were compared, aimed to understand the relative fitness of T. cinnabarinus resistant strains at different temperatures. The results indicated that compared with S strain, AbR and FeR strains had longer development duration at 15 °C but lower fertility at 20 °C-28 °C, and their relative fitness (represented by rm) was smaller at 15 °C but similar at 20 °C-31 °C. For AbR and FeR strains, the fitness cost was moderate at 15°C but lower at 20 °C-31 °C. However, at high temperatures (≥34 °C), FeR strain possessed remarkable fitness cost while AbR strain showed better fitness.
