Recombinant insect virus with reduced capacity for host-to-host transmission in the environment and methods to produce said virus

摘要

A noninfectious insect virus is described having an altered genetic element whose function is restored by genetic complementation, thereby again producing the insect infectious form of the virus. Also described is the insertion of a heterologous gene into the viral genome, such that an insect controlling or modifying substance is also produced by the virus for an improved bioinsecticidal effect and genetic stability of desired traits.
