Online published on 18 April, 2020. Abstract Oviposition behaviour of maize stem borer (Chilo partellus Swinhoe) on different genotypes of maize was studied at the School of Agricultural Sciences and Rural Development (SASRD), Nagaland University during 2013–2014. Eight genotypes viz., Tsük mendi, Boboü, Nashi nukjang temüsungla, DC61-A (Improved), Asubokipileu, Yetaü, Ayeghüu and Vijaya (composite) were evaluated. Reduction in oviposition showed significant variations in both the choice and no-choice tests: maximum reduction was in Nashi nukjang temüsungla (98.06%) followed by Yetaü (80.21%), Ayeghüu (69.81%) and Tsük mendi (63.51%) in choice test and Nashi nukjang temüsungla (75.70%) in no-choice test. The least reduction was exhibited by Boboü of 27.84% and 26.76% in both choice and no-choice tests.
