Malaria remains a significant global health challenge. In this study, we focus on the strategy of releasing Wolbachia-carrying male mosquitoes to control the spread of malaria. Considering the impact of vector-bias and temperature on malaria transmission, we establish a reaction–diffusion periodic-delay malaria model incorporating Wolbachia release strategy and vector-bias. Then, the basic reproduction number \(R_0\) is defined. The dynamic behavior of the model is analyzed in depth. A globally attractive disease-free T-periodic solution exists when \(R_ 0<1\) . Conversely, if \(R_ 0>1\) , then the disease exhibits uniform persistence. Furthermore, when all coefficients are constant and the vector-bias is disregarded, we demonstrate that the positive constant steady state is globally attractive, provided that \(R_0>1\) . Finally, numerical simulations are conducted to validate the theoretical results and further illustrate the effectiveness of the Wolbachia release strategy and vector-bias. These results suggest that the release of Wolbachia-carrying male mosquitoes can effectively reduce the transmission potential of malaria, and disregarding vector-bias can lead to an underestimation of the risk of malaria spread.
