High genetic variability for resistance to Bacillus thuringiensis toxins in a single population of diamondback moth

Article Abstract:

The diamondback moth has two genes that confer resistance to the Bacillus thuringiensis Cry toxins. One is dominant and one is partially recessive. Cross-resistance among insects from these two lines also differs.

Shared binding sites in lepidoptera for Bacillus thuringiensis Crt1Ja and Cry1A toxins

Article Abstract:

The Cry1Ja and Cry1A toxins of Bacillus thuringiensis share binding sites in six moth and butterfly species from different families. This means that the insects might develop cross-resistance to the two toxins.

Different mechanisms of resistance to Bacillus thuringiensis toxins in the indianmeal moth

Article Abstract:

Insects possess varying degrees of resistance to the Bacillus thuringiensis Cry1Ab and Cry1Ac toxins. The resistance appears to be mediated by a protease.
