Study cracks code for increasing sustainability of pest-killing proteins in genetically engineered crops

Farmers in dozens of countries have embraced crops genetically engineered to produce proteins from Bacillus thuringiensis (Bt) bacteria that kill some key pests yet are safe for people and wildlife. Although this biotech approach reduces reliance on insecticide sprays, thereby providing economic and environmental benefits, resistance to Bt crops has evolved in at least 11 species of pests. Thus, effective ways to combat such pest resistance are …

Cameras Reveal Secret Allies in the Fight Against Oilseed Rape Pests

In-field cameras have revealed surprising predators of two major oilseed rape pests, potentially improving pest control strategies. The two-year camera study, conducted across two UK sites, showed that the larval stages of predatory Carabid beetles play a key role in controlling the pollen beetle (Brassicogethes aeneus) and the brassica pod midge (Dasineura brassicae), two major threats to oilseed rape crops. While ecologists have long used came…
