Field experiment was conducted at the Experimental farm, Department of Entomology, School of Agricultural Sciences and Rural Development (SASRD), Nagaland University, Medziphema campus during 2018 and 2019 to study the effect of date of planting on the incidence of ginger shoot borer, Conogethes punctiferalis. Experiments were laid out in Split Plot Design. Pooled data revealed that the per cent reduction of C. punctiferalis population increased over time. The highest mean per cent reduction (39.24%) in the population of C. punctiferalis was observed in D₃ i.e. 16^th April planting while the lowest total mean per cent reduction was recorded on 15^th February planting (D1) with percent reduction of 36.13%. The mean per cent reduction was recorded to be 37.69% for D₂ i.e. 17^th March planting.
