Bt cotton hybrids viz., Ankur Jai BOIL Ankur Jai Bt, Ankur Jai non-Bt, RCH 134 BGll, RCH 134 Bt and RCH 134 non-Bt were used for evaluation of their effect on ovipositional preference of Spodoptera litura (Fabricius) adults at CCS Haryana Agricultural University, Hisar under laboratory conditions. Observations were recorded at 90 and 120 days after sowing (DAS). Twigs of cotton hybrids were brought to the laboratory and kept in ovipositional chamber for oviposition by four pairs of adults. Eggs were counted after 48 h of release. The studies revealed that S. litura adults showed no specific preference for egg laying on any of the hybrids at 90 and 120 DAS. However, leaves were preferred over flowers and bracts.
