Fall armyworm (Spodoptera frugiperda -JE Smith) also known as FAW, is a Lepidopteran pest that damages over 350 plant species which includes maize, rice, sorghum, sugarcane and wheat. FAW are strong fliers that contribute to the fast distribution of the pest.

Young larvae feed within whorl, it can skeletonize in the leaf lamina in a typical 'window-pane' damage. Larger larvae can cut the base of the plant. It can make larger holes, causing ragged and skeletonized leaves. 

Impact to the Crop

Feeding damage directly affects the quantity and quality of yield. Larvae damage silks and developing tassels that limit ear fertilization. Damaged cobs may lead to fungal infection and aflatoxins, decreasing grain quality.

How to control

√ Biological controls such as parasitic Hymenopterans acting as larval parasitoids and predators have recorded control against FAW.

√ Sex pheromone technique, biopesticides and some botanicals can control FAW.

√ Chemical control and IPM programs
