About

Bruce Tabashnik is a Regents' Professor and Department Head of Entomology at the University of Arizona. His research focuses on the evolution and management of insect resistance to transgenic plants. He is involved in advancing understanding of how insects develop resistance to genetically modified crops and developing strategies to manage and mitigate this resistance, contributing significantly to the field of entomology and insect science.

• Global Patterns of Insect Resistance to Transgenic Bt Crops: The First 25 Years

  Journal of Economic Entomology · 2023-01-04 · 197 citations

  editorialOpen access1st authorCorresponding

  Crops genetically engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) have improved pest management and reduced reliance on insecticide sprays. However, evolution of practical resistance by some pests has reduced the efficacy of Bt crops. We analyzed global resistance monitoring data for 24 pest species based on the first 25 yr of cultivation of Bt crops including corn, cotton, soybean, and sugarcane. Each of the 73 cases examined represents the response of…

• Transgenic cotton and sterile insect releases synergize eradication of pink bollworm a century after it invaded the United States

  (Bt). An analysis of computer simulations and 21 y of field data from Arizona demonstrate that the transgenic Bt cotton and sterile insect releases interacted synergistically to reduce the pest's population size. In Arizona, the program started in 2006 and decreased the pest's estimated statewide population size from over 2 billion in 2005 to zero in 2013. Complementary regional efforts eradicated this pest throughout the cotton-growing areas of the continental United States and northern Mexico…

• Functional redundancy of two ABC transporter proteins in mediating toxicity of Bacillus thuringiensis to cotton bollworm

  PLoS Pathogens · 2020 · 100 citations

  Evolution of pest resistance reduces the efficacy of insecticidal proteins from the gram-positive bacterium Bacillus thuringiensis (Bt) used widely in sprays and transgenic crops. Better understanding of the genetic basis of resistance is needed to more effectively monitor, manage, and counter pest resistance to Bt toxins. Here we used CRISPR/Cas9 gene editing to clarify the genetics of Bt resistance and the associated effects on susceptibility to other microbial insecticides in one of the world…
