It is shown that for a resonant magnetic field, the two cyclotron masses (m+* and m-*) in a parabolic quantum dot are split into two cyclotron masses, respectively. The cyclotron mass (m+*) decreases with decreasing the size of the quantum dot, the stronger the magnetic field strength, the larger the cyclotron mass. The lower branch of the cyclotron mass (m-*) increases linearly with increasing the magnetic field strength. The upper branch of the cyclotron mass (m-*) is larger than the bare band mass and enhances as the magnetic field strength increases.
