To clarify the adaptability of Oligonychus biharensis in different main rubber varieties, the development and reproduction of O. biharensis in six rubber varieties, 'Reyan 73397' 'Reyan 72059' 'Reken 628' 'Dafeng 95' 'PR107' and 'RRIM600' were observed by biological methods, and the experimental population life table was established. Different rubber varieties had significant effects on the development and reproduction of O. biharensis. The whole generation duration of O. biharensis was the shortest in 'RRIM600' and the longest in 'PR107', which was 11.40 d and 12.07 d, respectively. The survival rate of all mite stage was the highest after feeding on 'Reken 628', which was 100%. The value was 75% when feeding on 'PR107'. The longevity of female O. biharensis mites was prolonged and O. biharensis had large number of fecundity per female when feeding on 'Reken 628' and 'RRIM600', which wase 12.23 d and 28.66 eggs, 10.31 d and 29.56 eggs, respectively. There was no significant difference in the sex ratio of F1 generation of O. biharensis on different rubber varieties. According to the parameters of population life table, the net reproductive rate of O. biharensis was the largest in 'RRIM600' and 'Reken 628', which was 29.570 and 28.640, respectively. The intrinsic rate of increase and finite rate of increase of O. biharensis were the lowest in 'PR107', which was 0.257 and 1.292. The mean generation time and double population time were the longest in 'PR107', which was 9.539 and 2.702, respectively. In a comprehensive view, it showed that O. biharensis had a good adaptability when feeding on 'RRIM600' and 'Reken 628', while it went against the population growth of O. biharensis in 'PR107'.
