Hybrid megapests evolving in Brazil are a threat to crops worldwide Two extremely damaging crop pests have interbred to create hybrids resistant to more than one pesticide that could cause serious problems in many countries

“Two “megapests” that are already a major problem for farmers worldwide, the #cottonbollworm and the #cornearworm, have interbred in Brazil and swapped genes conferring resistance to pesticides.“

Proposed mechanism of Vip3Aa resistance through disruption of HaVipR1, based on its hypothesized role in mediating membrane repair in the midgut.

Bt proteins such as Vip3Aa are commonly used in #GMcrops to control lepidopteran #pests, but Vip3Aa resistance has been observed. This study identifies a gene in the crop pest #Helicoverpa armigera #CottonBollworm whose disruption confers resistance to Vip3Aa @plosbiology.org 🧪 plos.io/4kBtD89
