Medium larva and shot hole damage
Fall armyworm (FAW, Spodoptera frugiperda) is an exotic pest that was first detected on the Australian mainland in February 2020. Eradication has been determined to be unfeasible and it is now classified as an endemic pest. Reported to have a very wide potential host range, it hast so far shown a distinct preference for grass species with whorls, including sweet corn, maize and sorghum, where crop destruction can happen rapidly under high infestation levels.

The DARABUG insect development model provides a convenient and readily available means of predicting development times using different insect models, including FAW. Gridded climatic data of daily temperatures is used to generate estimates of the dates of occurrence for each stage throughout the whole lifecycle of an insect. The science behind the modelling is described in Regional and seasonal activity predictions for fall armyworm in Australia (Insect Science volume 1).
Cesar Australia have developed a wind dispersal forcasting tool to help predict FAW movement.
DPIRD (Western Australia) has released a Fall armyworm surveillance manual with instructions for using pheromone traps.
CottonInfo has a short video highlighting some of the similar characteristics between caterpillars and an Endemics to exotics factsheet that looks at some of the differences between armyworm species found in the tropics.
