Effect of agricultural intensification on the genetic diversity of Helicoverpa armigera

Agricultural intensification affects natural and crop ecosystems, and increases the risk of agricultural pests in agroecosystems. Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) is an important pest that damages a wide range of crops. However, the effect of agricultural intensification on the genetic diversity of this pest is still unclear. In this study, we investigated the effects of the compo- sition and configuration of the landscape on the genetic diversity of the agricul- tural pest...
