The fall armyworm (FAW), Spodoptera
frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is an
economically important polyphagous pest native to the
Americas. The pest has recently introduced to India and
causing severe damage to maize and other crops. The
occurrence of fall armyworm on fodder maize (Zea
mays L), Guinea grass (Megathyrsus maximus) (Jacq.),
para grass (Brachiaria mutica) (Forssk.) and green amaranth
(Amaranthus viridis L) is reported first time from
Goa, India. The damage incidence of 16 to 52% was
recorded on fodder maize. The other host plants viz.,
Guinea grass, para grass and green amaranth recorded
damage incidences of 9.0, 4.0 and 13.0%, respectively.
The pest was identified based on morphological characters
and molecular techniques. Phylogenetic analysis of
COI gene sequence revealed that fall armyworm on
fodder maize from Goa is clustering with the fall armyworm
isolates from India, Nigeria, Ghana, Kenya, Canada
and Brazil. Goa isolate is aligning with the “Rice”
strain of fall armyworm and not with “Corn” strain.
Studies on the biology of fall armyworm indicated that
longer larval and pupal developmental period (18.6 and
10.7 days) was recorded on Guinea grass and green
amaranth, respectively. The highest number of eggs
was recorded from fall armyworm population reared
on fodder maize as compared to those reared on other
host plants. Longer life cycle was recorded on Guinea
grass and green amaranth. Shortest larval and pupal
period and faster life cycle of fall armyworm was recorded
on fodder maize compared to other host plants
indicating that fodder maize was the most preferred host
for S. frugiperda in India.
