Multiple roads to swarming: divergent molecular machineries drive the repeated evolution of locusts

Maéva Angélique Techer, Sheina B. Sim, Olga Dudchenko…·Hojun Song

The paper shows that locust swarming evolves through diverse molecular pathways rather than shared genes, highlighting flexible regulatory architectures and modular systems.

Identification of a novel resistance gene which provides insight into Vip3Aa mode of action in Helicoverpa armigera

Andreas Bachler, Amanda Padovan, Craig J. Anderson…·Tom Walsh

This study identifies a novel gene, HaVipR1, responsible for Vip3Aa resistance in Helicoverpa armigera through genetic crosses and genomic analysis, showing its role in conferring resistance independently of known genes.

Rapid evolution of pesticide resistance via adaptation and interspecific introgression in a major North American crop pest

Henry L. North, Zhen Fu, Richard P. Metz…·Gregory A. Sword

This study identifies two mechanisms of rapid pesticide resistance evolution in Helicoverpa zea: introgression from H. armigera and intraspecific adaptation.

Whole genome comparisons reveal panmixia among fall armyworm (Spodoptera frugiperda) from diverse locations

Katrina Schlum, Kurt Lamour, Caroline Placidi De Bortoli…·Juan Luis Jurat‐Fuentes

The paper analyzes whole genome sequences of fall armyworm samples from multiple locations to show panmixia, with minor gene flow reduction between two host strains in the USA.
