Two species into one: bottleneck history of Helicoverpa zea from Helicoverpa armigera revealed by DNA barcoding

The use of mitochondrial DNA Cytochrome Oxidase I (mtDNA COI) gene in species identification has gained popularity in recent years, with its effectiveness in identifying cryptic and new species demonstrated in birds and Lepidoptera.

The Influence of Transgenic Cottons Expressing One or Two Bacillus Thuringiensis Proteins Against Helicoverpa zea (Lepidoptera: Noctuidae) and Factors Affecting B. t. Resistance in H. zea

, 2002
Because control of bollworm with transgenic Bacillus thuringiensis var. kurstaki cottons that express the Cry1Ac protein has not been absolute compared to that of tobacco budworm, transgenic cottons expressing two B. t.
