Symbionts and immune defence in lepidopteran crop pests
… their resistance against chemical pesticides and Bt crops. These factors emphasize the importance to the development of technologies for rapid field diagnosis and specific environmentally-safe pest control. Here we show that different molecular and biochemical tools can be widely useful in studies …

Investigating host use and migration by the corn earworm (Noctuidae: Helicoverpa zea) using stable isotope and morphometric techniques.
… a caterpillar-specific insecticidal protein (Bt toxin) has focused renewed attention on the issue of southward migration of Helicoverpa zea because it could have a major effect on the rate at which this pest evolves resistance to the Bt toxin. Corn is a major host of H. zea and since there is …

Modeling insect resistance to transgenic corn and cowpea
The global area planted to Bt crops covered over 66 million hectares in 2011. Insect resistance management (IRM) is implemented to protect the efficacy of commercial transgenic crops expressing Bacillus thuringiensis toxins because the benefits of the pest susceptibility to Bt toxins is considered …
