 ABSTRACT

Fall armyworm, Spodoptera frugiperda is most destructive pest of agricultural crops especially maize all over the world. The pest has got primary pest status due to high feeding, migration and reproduction potential. The present study was conducted to check the biology of S. frugiperda under laboratory conditions. The flattened and pale green eggs were laid by female which turn golden yellow and then black prior to hatching. The mean number of eggs laid by female were 981.76±99.67. The incubation period of pest was 2-3 days. There were six larval instars which lasted for about 14-18 days. The duration periods of first, second, third, fourth, fifth and sixth larval instars were 2.23±0.56, 2.29±0.59, 1.50±0.58, 1.53±0.69, 2.35±0.65 and 3.60±0.97 days, respectively. Pupa was obtect. The female longevity was greater than male while male body length was small as compared to female. The average wingspan of female and male was 3.10 and 3.14 cm, respectively. Fall armyworm, Spodoptera frugiperda is serious pest of maize crop and attain status of primary pest.
