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