L'invention concerne des isolats de Bacillus thuringiensis désignés par B.t.) PS157C1, B.t. PS86A1 et B.t. PS75J1 qui sont actifs contre les aphidiens. Ces isolats ou les variantes de ceux-ci peuvent être utilisés pour détruire ces parasites. De plus, les gènes codant de nouvelles delta-endotoxines peuvent être extraits de ces isolats et transférés dans d'autres microbes ou plantes hôtes. L'expression des delta-endotoxines des hôtes microbiens permet de détruire les aphidiens alors que les plantes transformées selon l'invention deviennent résistantes aux aphidiens. The subject invention concerns Bacillus thuringiensis isolates designated B.t. PS157C1, B.t. PS86A1, and B.t. PS75J1, which are active against aphid pests. Thus, these isolates, or variants thereof, can be used to control such pests. Further, genes encoding novel delta -endotoxins can be removed from these isolates and transferred to other host microbes, or plants. Expression of the delta -endotoxins in microbe hosts results in the control of aphid pests, whereas transformed plants become resistant to aphid pests.
