Measurements of the c-axis resistivity and magnetoresistance have been usedto investigate the pseudogap (PG) behavior in Bi_{2+z}Sr_{2-x-z}La_xCuO_y(Bi-2201) crystals at various hole densities. While the PG opening temperatureT* increases with decreasing hole doping, the magnetic-field sensitivity of thePG is found to have a very different trend: it appears at lower temperatures inmore underdoped samples and vanishes in non-superconducting samples. These datasuggest that besides the field-insensitive pseudogap emerging at T*, a distinctone is formed above T_c as a precursor to superconductivity.Comment: 7 pages, 6 figures, accepted for publication in Europhysics Letters  (initially submitted to PRL on 14 June 2000
