Description To study the egg laying pattern of Sesamia inferens (Walker) on maize (Zea mays L.), a set of variable number of 12-day old plants, i e 1, 2, 3 and 4 plants in each set of resistant cultivar HQPM 1 and susceptible cultivar, Basi Local were offered to a single pair of adult S. inferens in versatile insect rearing cage. The number of eggs laid on HQPM 1 was 47.7 % more than the number of eggs laid on Basi Local. When only one plant was available for oviposition, the female laid 84% of its eggs complement on it both in case of HQPM 1 and Basi Local. The number of eggs was divided unequally when two plants were made available with the first plant receiving 60-70% of the eggs. The maximum number of plants utilized for depositing the eggs was four out of ten plants offered to the female, although at times, the female oviposited six plants as well but the total number of eggs did not increase when the number of plants exceeded more than four, on contrary, it got reduced. The distribution pattern of eggs on plants resulted in the decline in number of eggs per plant with increase of every additional plant. The egg distribution within a plant showed significantly more percentage (58.57) of eggs on first leaf sheath followed by second leaf sheath (27.19) and least number on basal leaf sheath (14.24). The total oviposition period was observed to be seven days with average fecundity as 405 and maximum number of eggs (174) obtained on second day of emergence of adults.
