We investigate resonant wave-particle interactions in weakly turbulent low-beta plasmas. We are interested in the scenario in which wave energy is injected at large scales and cascades to smaller scales via three-wave interactions. The resonant interactions between different types of waves and particles are widely different in their efficiency. In this work, the behavior of the resonant interactions are investigated along with the coupled evolution of the anisotropic wave power spectra and particle velocity distributions in 2D numerical simulations. The simulations show that the efficiency of resonant interactions changes as the particle velocity distributions evolve. The implications of our results for solar flares are discussed.
