| description | Fall armyworm (Spodoptera frugiperda) (FAW) is an important invasive pest of maize. The
young FAW larva disrupts the photosynthetic system by feeding on the leaves. The older
caterpillar interferes with pollination and fertilization processes, destroying the tassel and
silks, or it bores into the maize cob, reducing harvest quality and predisposing the cob
to secondary infections. The infested plant responds by channeling or converting the primary
metabolites into secondary metabolites for plant defense, further reducing crop yield.
The devastating feeding effect on maize becomes even more severe when maize plants are
exposed to prolonged drought, during which the production of secondary metabolites is
optimum. These secondary metabolites are food for herbivorous insects like the fall armyworm.
Naturally, plants possess several adaptive features which enable them to cope
and survive herbivorous insect attacks without compensating yield for plant defense. Such
features include: thickening of the leaf cuticle of the epidermal cell walls, production of certain
allelochemicals, defense proteins and the toxic chemical compound, favone glycoside
(silk maysin). This review attempts to critically appraise the physiological implications of
fall armyworm damage on developmental processes and maize yield. Understanding the
mechanisms of various adaptive traits that confer resistance to maize against herbivorous
insect damage would assist greatly in crop improvement processes. |
