  Pulsars play a crucial astrophysical role as the highly energetic compact
radio, X-ray, and gamma-ray sources. Our previous works show that the radio
pulsars found as the pulsing gamma sources by the Large Area Telescope (LAT) on
the board of the Fermi Gamma-Ray Space Telescope have high values of magnetic
field near the light cylinder, two-three orders of magnitude stronger comparing
with the magnetic fields of radio pulsars: $\log B_{lc}$ (G) are 3.60-3.95 and
1.75. Moreover, their losses of the rotation energy are also three orders
higher than the corresponding values for the main group of radio pulsars on
average:$\log \dot E$ (erg/s) = 35.37-35.53 and 32.64. The correlation between
gamma-ray luminosities and radio luminosities is found. It allows us to select
those objects from all set of the known radio pulsars that can be detected as
gamma pulsars with the high probability. We give the list of such radio pulsars
and propose to search for gamma emisson from these objects. On the other hand,
the known catalog of gamma pulsars contains some sources which are not known as
radio pulsars at this moment. Some of them have the large values of gamma
luminosities and according to the obtained correlation, we can expect marked
radio emission from these objects. We give the list of such pulsars and
expected flux densities to search for radiation at frequencies 1400 and 111
MHz.
