  Traditional searches for radio pulsars have targeted individual small regions
such as supernova remnants or globular clusters, or have covered large
contiguous regions of the sky. None of these searches has been specifically
directed towards giant supershells, some of which are likely to have been
produced by multiple supernova (SN) explosions from an OB association. Here we
perform a Montecarlo simulation of the pulsar population associated with
supershells powered by multiple SNe. We predict that several tens of radio
pulsars could be detected with current instruments associated with the largest
Galactic supershells (with kinetic energies >~ 10^{53} ergs), and a few pulsars
with the smaller ones. We test these predictions for some of the supershells
which lie in regions covered by past pulsar surveys. For the smaller
supershells, our results are consistent with the few detected pulsars per
bubble. For the giant supershell GSH 242-03+37, we find the multiple SN
hypothesis inconsistent with current data at the 95% level. We stress the
importance of undertaking deep pulsar surveys in correlation with supershells.
Failure to detect any pulsar enhancement in the largest of them would put
serious constraints on the multiple SN origin for them. Conversely, the
discovery of the pulsar population associated with a supershell would allow a
different/independent approach to the study of pulsar properties.
