The subject invention concerns novel Bacillus thuringiensis strains containing parasporal proteins with pesticidal properties against whitefly, aphid, jassid, and possibly other sucking insects of agronomic importance, and peptide sequences to these proteins that can be used to obtain structural genes. The spores or crystals of these microbes, or mutants thereof, are useful to control hymenopteran pests in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.
L'invention concerne des nouvelles souches de Bacillus thuringiensis contenant des protéines parasporales, lesquelles possèdent des propriétés pesticides contre la mouche blanche, le puceron ou la cicadelle, ou le cas échéant contre d'autres insectes suceurs importants sur le plan agronomique; elle concerne également des séquences peptidiques de ces protéines que l'on peut utiliser pour obtenir des gènes de structure. Les spores ou cristaux de ces microbes, ou de mutants de ceux-ci, sont utiles pour lutter contre les hyménoptères nuisibles, dans divers environnements. On peut utiliser les gènes de l'invention pour transformer divers hôtes dans lesquels ces nouvelles protéines toxiques peuvent être exprimées.
