Abstract: A method of inducing transposition in a transgenic embryo, sperm and egg is described, comprising the steps of (a) generating a first adult transgenic organism comprising within its genome one or more copies of a transposon; (b) generating a second adult transgenic organism comprising within its genome one or more copies of a gene encoding a transposase cognate for the transposon and/or a sequence capable of regulating expression of the gene encoding the transposase; (c) crossing the first adult transgenic organism with the second transgenic adult organism to provide a progeny which comprises, in the genome of one or more of its cells, both (i) one or more copies of the transposon and (ii) a gene encoding a transposase cognate for the transposon, wherein the gene encoding the transposase is under the control of one or more inducible regulatory sequences which permit expression of the transposase, and (d) expressing the gene encoding the transposase in the embryo, sperm or egg to cause mobilization of the tran

Abstract: The invention relates to a method for producing a protein of interest comprising transforming a target insect with a non-viral expression system that expresses the protein in the insect larvae, breeding the insect to produce larvae, culturing the larvae and isolating the protein from the larvae.

Abstract: The inventon provides a method for producing a library of genetic mutations in a cell population by insertional mutagenesis, wherein a viral vector comprising a transposon is used to deliver said transposon to said cell population, which cell population stably expresses the cognate transposase for said transposon, and the transposon is mobilised to give a rise to the genetic mutations.

Abstract: The present invention provides a method for controlling a population of target pests, comprising: a) providing gene comprising a coding sequence encoding one constituent of an enzyme/pro-pesticide system and a promoter capable of driving the coding sequence in the target plants or vertebrate host; b) transforming the target plant or vertebrate with the gene; and c) administering to the transformed population of target plant or vertebrates the remaining constituents of the enzyme/pro-pesticide system such that inactive pro-pesticide is converted to active pesticide on or within the transformed plant or vertebrate host leading to the death of any invading population of target pests.
