miR‐252a‐5p targets OVOL to regulate ovary development and egg viability (hatchability) in Helicoverpa armigera This paper describes a study on the mechanisms of reproductive development in the cotton bollworm (Helicoverpa armigera). Cotton bollworm poses a serious threat to agricultural production as a polyph...

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
