The paper studies hybridization between native and invasive Helicoverpa moths in Brazil, showing rapid adaptive introgression of pesticide resistance genes with implications for global food security.

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.

This study examines population genetics in four flying-fox species, finding isolation-by-distance, hybridization, and recent secondary contact shaping their evolution.

This study shows that knocking out SfVipR1 in Spodoptera frugiperda confers high-level resistance to Vip3Aa toxin but not Cry1Fa.

This study reports the chromosome-level genomes of two invasive ambrosia beetles, revealing chromosomal rearrangements and repetitive element differences linked to their life history traits.

The paper presents the first reference genome of the redlegged earth mite, identifying genes associated with pesticide resistance and population structure in its invasive range.

The paper uses RADseq to analyze genetic diversity and invasion pathways of Solenopsis geminata, finding genetic bottlenecks and multiple secondary introductions.

The paper analyzes population genomic data of the fall armyworm to show multiple introduction events and gene flow across the Old World.

The paper uses genome-wide SNPs to reclassify cassava whitefly species and subgroups in Africa, revealing hybridization and population structure.
