Development Of Anchor Loci To Map A Bt Resistance Factor In The Domesticated Silkworm, Bombyx Mori, Marc Chatenay-Lapointe

Senior Honors Projects

The BT toxin is an insecticide produced by the bacterium Bacillus thuringiensis, and millions of acres of genetically modified crops expressing this agent have been planted. However, with such widespread use, there is a great potential for pests resistant to this toxin to develop. An understanding of how BT resistance operates and is inherited is central to ensuring continued use of the transgenic crops. Bombyx mori, the domesticated silkworm, is the model organism for the Lepidoptera, an order of insects containing many important agricultural pests. Screening shows that BT resistance is present in some silkworm strains, and linkage group 15 ...
