Genetically modified (GM) cotton fortified with cry1Ac (crystal 1Ac) gene derived from the soil bacterium Bacillus thuringiensis (Bt), commonly known as Bt-cotton, was approved in 2002 for commercial cultivation in India. The Cry1Ac protein expressed in Bt-cotton is toxic to the three major cotton bollworms: the American bollworm, Helicoverpa armigera (Hübner) (Lepidoptera:Noctuidae), pink bollworm Pectinophora gossypiella (Saunders) (Lepidoptera:Gelechiidae) and spotted bollworms Earias vittella (Fabricius) (Lepidoptera:Noctuidae) and Earias insulana (Boisduval) (Lepidoptera:Noctuidae).Full Text

Pink Bollworm (PBW) incidence on Bollgard-II (BG II) cotton was not observed so far in North Zone of India. During 2018–19 cotton season, BG II cotton was found infested withPink Bollworm at one location in Haryana and two locations inPunjab near cotton ginning and oil extraction units. Cotton seeds are being procured from the central and south India by many units where PBW has already acquired resistance against BG II hybrids. Bioecological and resistance monitoring studies of larvae collected from the infested location revealed absence of larval diapauses in surviving population and resistance levels equivalent to central/south zone populations. The threat perception of pink bollworm in north zone on BG II cotton due to transport of resistant larvae along with cotton seed is discussed.Keywords
