Previously, a South African Trichoplusia ni single capsid nuclear polyhedrosis virus (TnSNPV) isolate was partially characterized as a novel baculovirus. During the process of the characterization, a few late genes of the virus were identified. This thesis describes a molecular characterization of the TnSNPV early genes to gain insight into the functional roles of these genes, their unique features and further determination of the placement of TnSNPV in baculovirus phylogeny.enBaculovirusesInsect pestsTrichoplusia NI singleBiological insecticidesSouth AfricaUniversity of the Western Cape
