Simple Summary Eotetranychus sexmaculatus and Oligonychus biharensis are devastating mite pests of the valuable tropical crop, rubber trees. Outbreaks of both spider mite species are associated with high temperatures and drought stresses. To evaluate both intra- and interspecific competition and the effects of temperature, we analyzed the population dynamics of E. sexmaculatus and O. biharensis under different temperature treatments. The results reveal the presence of both types of competition and demonstrate that O. biharensis is always more competitive than E. sexmaculatus, regardless of the temperature and the initial ratio. Therefore, O. biharensis has the potential to become a dominant pest of rubber trees. These findings provide a theoretical basis for early detection and effective management strategies for spider mites on rubber trees.
