Fall armyworm

Larva — Lepidoptera

What is an opportunist?

An "opportunist" is a population (fungi, bacteria, insects…) that takes advantage of a favourable environment to settle in, multiply and feed on it. It often develops when the natural defences of the affected organism are weakened — for genetic reasons or linked to context (water stress, deficiencies, nutritional imbalances, overcrowding…). This is typically the case in monocultures, where a single host plant, uniform and present in large numbers, offers ideal ground for it to spread.

Identification key : Leaf-eating caterpillar (Larva) Butterflies and moths (Adult (and nymphs resembling the adult))

Scientific name : Spodoptera frugiperda

Other names : Spodoptera frugiperda

Night-flying moth native to tropical and subtropical America that has spread since 2016 across Africa, Asia and Oceania. Its caterpillars, marked with a pale inverted Y on the head, devour young leaves and the whorl of maize, leaving abundant droppings, and may also bore into the cob. It is highly polyphagous (maize, sorghum, rice, sugarcane, cotton, vegetables) and the moths travel long distances.

Crops affected : Corn, Cotton, Quinoa, Rice, Sorghum, Sugarcane, Wheat
