  In this letter, we investigate the changes in the quantum vacuum energy
density of a massless scalar field inside a Casimir cavity that orbits a
wormhole, by considering the cosmological model with an isotropic form of the
Morris-Thorne wormhole, embedded in the FLRW universe. In this sense, we
examine the effects of its global curvature and scale factor in an instant of
the cosmic history, besides the influences of the local geometry as well as of
inertial forces, on the Casimirenergy density. We also study the behavior of
this quantity when each plate is fixed without rotation at the opposite sides
of the wormhole throat, at zero and finite temperatures, taking into account
the effective distance between the plates through the wormhole throat.
