Cyt1Aa from Bacillus thuringiensis subsp. israelensis is toxic to the diamondback moth, Plutella xylostella, and synergizes the activity of Cry1Ac towards a resistant strain
Applied and Environmental Microbiology 67 (12), 5859-5861
Abstract: The Bacillus thuringiensis subsp. israelensis cytolytic protein Cyt1Aa was found to be toxic to an insecticide-susceptible laboratory population of Plutella xylostella. Cry1Ac-resistant populations of P. xylostella showed various degrees of resistance to Cyt1Aa. Cyt1Aa/Cry1Ac mixtures showed a marked level of synergism in the Cry1Ac-resistant populations.
