A method for killing pests (e.g. insects) comprising administering material from Xenorhabdus species (e.g. X. nematophilus) such as cells or supernatants orally to the pests, either alone or in conjunction with Bacillus thuringiensis or pesticidal materials derived therefrom. Also disclosed is an isolated pesticidal agent (and compositions comprising the same) characterized in that it is obtainable from cultures of X. nematophilus or mutants thereof, has oral pesticidal activity agent Pieris brassicae, Pieris rapae and Plutella xylostella, is substantially heat stable to 55° C., is proteinaceous, acts synergistically with B. thuringiensis cells as an oral pesticide and is substantially resistant to proteolysis by trypsin and proteinase K. DNA encoding pesticidal activity is also disclosed.
An insecticidal composition adapted for oral administration to an insect comprising a pesticidal material obtainable from a Xenorhabdus species, or a pesticidal fragment thereof, or a pesticidal variant or derivative of either of these.
A composition as claimed in any one of the preceding claims which comprises supernatant taken from cultures of cells of Xenorhabdus species.
A composition according to any one of the preceding claims wherein the Xenorhabdus species is Xenorhabdus nematophilus.
A composition as claimed in any one of the preceding claims which comprises a further pesticidal material not obtainable from Xenorhabdus.
A composition according to any one of the preceding claims which further comprises an agriculturally acceptable carrier.
A method for killing or controlling insect pests, which method comprises administering to a pest or the environment thereof a composition according to any one of the preceding claims.
A microorganism comprising Xenorhabdus strain NCIMB 40886.
A microorganism comprising Xenorhabdus strain NCIMB 40887.
A pesticidal agent which comprises a a toxin comprising a protein which is encoded by DNA which includes SEQ ID No. 1 or a variant or fragment thereof.
An isolated pesticidal agent characterised in that it is obtainable from cultures of X. nematophilus or mutants thereof, has oral pesticidal activity against Pieris brassicae, Pieris rapae and Plutella xylostella, is substantially heat stable to 55° C., is proteinaceous, acts synergistically with B. thuringiensis cells as an oral pesticide, and is substantially resistant to proteolysis by trypsin and proteinase K.
A recombinant DNA which comprises or hybridises under stringent conditions with all or part of the sequence of FIG. 2, and which encodes a pesticidal material.
