- Helicoverpa armigera (Lepidoptera: Noctuidae), the boll worm or corn ear worm, has a widespread distribution in tropical, subtropical and warm temperate regions, and is an important pest of many crop plants.
- The cotton bollworm, Helicoverpa armigera (Hu¨bner) (Lepidoptera: Noctuidae), is one of the most serious agricultural pests in Asia, Africa, southern Europe and Australia. Due to heavy selection pressure over the past 40 years, it has developed resistance to organochlorine, carbamate, organophosphate and pyrethroid insecticides in many countries and has begun to show some tolerance to newer chemistries such as fipronil, chlorfenapyr, spinosad and indoxacarb. The failure of insecticides to control resistant H. armigera has been a strong incentive for the development and adoption of Bt cotton genetically engineered to withstand bollworm attack.
- RecentstudieshavefocusedondeterminingfunctionalgenesandmicroRNAsinthepestHelicoverpa armigera (Lepidoptera: Noctuidae). Most of these studies used quantitative real-time PCR (qRT-PCR). Suitable reference genes are necessary to normalize gene expression data of qRT-PCR. However, a comprehensive study on the reference genes in H. armigera remains lacking.  .
