Abstract:
The investigations were carried out on study of biology of fall armyworm on maize revealed that the average fecundity of this pest was 1015 eggs per female and the incubation period was 3.32 days. During larval development, larvae passed through six instars and total larval duration was observed to be 18.02 days, wherein first, second, third, fourth, fifth and sixth instar were 2.6, 2.7, 2.5, 2.4, 2.7 and 5.1 days respectively. The pupal period lasted for 9.92 days. The pre oviposition, oviposition and post oviposition period was observed as 10, 3.02, 4.40 days respectively. Mean longevity of males was observed as 9.10 days while in case of females, it was 11.52 days. The total life cycle of male and female was completed in 40.34 and 42.76 days. The morphometric data viz., larval body length; pupal length and adult body length and wing span were measured.
