Population structure and gene flow in the global pest, Helicoverpa armigera.

Molecular ecology - 1 Nov 2016

Anderson C J, Tay W T, McGaughran A, Gordon K, Walsh T K

Abstract excerpt

Helicoverpa armigera is a major agricultural pest that is distributed across Europe, Asia, Africa and Australasia. This species is hypothesized to have spread to the Americas 1.5 million years ago, founding a population that is at present, a distinct species, Helicoverpa zea. In 2013, H. armigera was confirmed to have re-entered South America via Brazil and subsequently spread. The source of the recent incursion...
