Fall armyworm

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. It has since been been detected in the Northern Territory, northern Western Australia and northern New South Wales. Eradication has been determined to be unfeasible and it is now classified as an endemic pest.

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 life-cycle of an insect.
