Oviposition preference of pink stem borer Sesamia inferens was studied on twenty maize germplasm.Results of present investigations revealed all the maize germplasm were more or less preferred for egglaying and no germplasm showed a complete antixenosis. The site selected by adult female moths of S.inferens for oviposition on all the maize germplasm was inner side of leaf sheath. Significant variationswere revealed regarding the total number of eggs laid by S. inferens female on different maizegermplasm. The total number of eggs laid were ranged from 29.67 to 191.00. The total number of eggswere laid maximum on the germplasm DC-2 (191.00), E-62 (149.67) and HKI-193-2 (145.00) whereas itwas observed minimum on WP-21 (29.67), HKI-193-1 (37.67) and E-63 (40.67). Significantly highernumber of eggs were deposited on first leaf sheath followed by second leaf sheath, basal leaf sheath andthen third leaf sheath. Least number of eggs were deposited on third leaf sheath. Only four germplasmwere preferred for egg laying on third leaf sheath viz., DC-2, JCY-2-7, E-62 and HKI-193-2. Maizegermplasm DC-2, HKI-193-2 and E-62 received higher number of eggs on different leaf sheaths incomparison to WP-21, E-63 and HKI-193-1. Thus, the maize germplasm DC-2, HKI-193-2 and E-62were preferred for egg laying indicating their susceptibility in comparison to least susceptible germplasmWP-21, E-63 and HKI-193-1, as these germplasm were less preferred for oviposition.
