Abstract:
The life table of FAW was studied on maize at room temperature under laboratory conditions at Department of Entomology, Anbil Dharmalingam Agricultural College and Research Institute, Trichy. Pre-oviposition occurs from the 29^th to the 31^st day of pivotal age. The oviposition began on the 32^nd day of pivotal age and continued it until 40^th day. On the 36^th day of pivotal age, females contributed the maximum progeny (mx = 577) in the life cycle. The average generation period (T) was 35.51 days, and the net reproductive potential (R_o) was 479.89 females. The number of hypothetical F2 females was found to be 230290.09. The egg stage contributed the maximum (52.20%), while larvae, pupae, and adults contributed 37.77, 2.15, and 0.21 percent, respectively, in a stable age distribution of FAW on maize.
