Abstract: The Spodoptera spp. are important lepidopteran pests which cause severe damages to major agricultural crops in many parts of the world. The SlNPV member of the Baculoviridae, a pathogen of Spodoptera spp., is considered as a potential control agent of these pests. Infection of S. littoralis larvae with SlNPV revealed the phenomenon of delayed or blocked larval moulting. Such inhibition was attributed in other nuclear polyhedrosis viruses (NPVs) to the activity of a viral-encoded ecdysteroid UDPglucosyltransferase (egt). In order to study further the interaction of SlNPV with its host, we isolated the egt gene from the viral genome using an Autographa californica NPV (AcNPV) gene-specific probe. Sequence determination of a 1925 bp portion of the hybridizing DNA fragment revealed an open-reading frame of 1548 bp that exhibits significant percentage of identity to egt identified in other NPVs. The detection of egt activity in media of SlNPV-infected cells implied the production and secretion of a functional egt protein.
