title: Involvement of spindles of an entomopoxvirus (EPV) in infectivity of the EPVs to their host insect.
abstract: The biological function of entomopoxvirus (EPV) spindles (inclusion bodies that lack virions), has not been elucidated. We characterized the function of EPV spindles in the cupreous chafer, Anomala cuprea (Coleoptera: Scarabaeidae). Spheroids or spheroids mixed with spindles of Anomala cuprea EPV were administered per os to the A. cuprea larvae. A significant increase in infectivity was induced by the addition of spindles to the spheroids, strongly suggesting that the spindles play an important role in the infection of the host insect.
