Molecular Evolutionary Mechanisms of -Type Variant Associated with Resistance to Neonicotinoid Insecticides in Field Populations of .

The evolution of insecticide resistance has threatened the control of . Research on mechanisms behind neonicotinoid resistance in remains incomplete. This study examined P450-mediated resistance to neonicotinoids in a resistant strain (XA-2017-3G).

Lack of Known Target-Site Mutations in Field Populations of in China from 2019 to 2021.

The Asian corn borer, (Guenée) (Lepidoptera; Pyralidae), is one of the most destructive insect pests of corn, for which chemical insecticides have been the primary method of control, especially during outbreaks. Little information is currently available on the status of insecticide resistance and associated mechanisms in field populations. Invasions and outbreaks of in China in recent years have increased chemical application in corn fields, which adds to the selection pressure on .
