To clarify the adaptability of Eotetranychus sexmaculatus in different main rubber strains in rubber planting areas in China, the development and reproduction of E. sexmaculatus in six rubber strains, Reyan 73397, Reyan 72059, Reken 628, Dafeng 95, PR107 and RRIM600, were observed by biological methods, and the experimental population life table was established. The results showed that different rubber strains had significant effects on the development and reproduction of E. sexmaculatus. The whole generation duration of E. sexmaculatus was the shortest in RRIM600 strain and the longest in Reken 628, which was 10.93 d and 12.82 d, respectively, followed by Reyan 73397, Reyan 72059 and PR107, with no significant difference. The juvenile survival rate of Dafeng 95 strain was the lowest, only 65.00%, and there was no significant difference among other strains. The large number of fecundity per female was the largest when feeding on RRIM600, which were 18.38 eggs. PR107 strain was the most unfavorable to the survival and reproduction of adult mites, and its life span and spawning period were also the shortest. There was significant difference in the sex ratio of F1 generation of E. sexmaculatus on different rubber strains and the female rate of Dafeng 95 was the highest, which was 78.67%. Through the establishment of population life table for parameter analysis, the intrinsic rate of increase and finite rate of increase of E. sexmaculatus were the largest in RRIM600, and the lowest in Reyan 73397, followed by Reyan 72059, Reken 628 and PR107, which was no significant difference among the Reyan 72059, Reken 628 and PR107. The double population time was the shortest in RRIM600, while was the longest in Reyan 73397, followed by Reyan 72059, Reken 628 and PR107. In a comprehensive view, it showed that E. sexmaculatus had a high fitness when feeding on RRIM600 and a low fitness on PR107.
