Research ArticleOpen accessIn the abstractSynthetic Pyrethroid Resistance in Field Strains of Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) in Tamil Nadu, South IndiaP. Duraimurugan, A. RegupathyResistance to synthetic pyrethroids was diagnosed in the field population of American bollworm, Helicoverpa armigera (Hubner) from Coimbatore, Tamil Nadu, South India during 2003-2004 cropping seasons. A Discriminating Dose (DD) bioassay technique was used to monitor fortnightly changes in resistance at Coimbatore where number of crops served as host plants for this pest. The resistance level of various synthetic pyrethroids … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,856 accessesView PDF Cite
