Fall armyworm update and alert
Publication date: February 28, 2020
Fall armyworm (Spodoptera frugiperda) is an exotic pest that has recently been detected for the first time in Australia. Fall armyworm was originally found on the Torres Strait islands of Saibai and Erub in January 2020. Since then it has been detected in Queensland at Bamaga, Croydon, South Johnstone, Tolga, Lakeland, the Burdekin, Bowen, Bundaberg and Emerald and in the Northern Territory and northern Western Australia. Most recently, in October 2020 a single male moth was found in a trap in Northern New South Wales between Moree and Boggabilla near the Queesnland border.
The invasive moth’s larvae can cause significant and rapid damage to crops. The pest is known to feed on more than 350 different plant species, including fruit and vegetable crops.
The Queensland Department of Agriculture and Fisheries is leading the response and working with fellow Government agencies; Research and Development Corporations; industry groups and communities to assess the distribution, host range and threat of the pest.
Meanwhile, the Department of Agriculture, Water and Environment is implementing a fall armyworm national response plan with Queensland and Australia’s other states and territories.
The key characteristics of fall armyworm are:
If you suspect fall armyworm on your farm, you should immediately contact the QLD Department of Agriculture and Fisheries on 13 25 23. Early detection and reporting are essential.
More information on how to identify and protect against the pest can be found via this fact sheet and on the QLD Department of Agriculture and Fisheries website.
The adult moths are capable of flying long distances aided by wind currents. All life stages can be moved on infested plant material.
Adult moths are nocturnal and are most active during warm, humid evenings.
Fall armyworm larvae are most active during late summer and early autumn months, however they can be active year-round in tropical areas.
Fall armyworm is most likely found in warm, moist regions with little forest cover.
Depending on the plant, fall armyworm can cause significant and sudden crop damage and collapse if left unchecked.
Symptoms of fall armyworm include leaf damage such as pinholes, windowing, tattered leaf margins and defoliation of plants.
Growers should also look out for tiny larvae, less than 1 mm, that are more active at night, eating pin holes and transparent windows in leaves and bigger larvae grazing on leaves, stems and fruit, and leaving behind insect excrement.
In grass-like plants, larvae are often in plant whorls where leaves branch from the stalk.
Early detection is essential. Regularly check all your crops or pastures for unusual insect activities.
Key to the control of any pest is an integrated pest management approach. The Department, in collaboration with industry, is working to identify strategies and tactics for the medium to long-term response.
With any pesticides used for fall armyworm, it is essential that the implications for chemical resistance development in other pests (e.g. Helicoperva) and the potential impact on natural enemies are considered. Fall armyworm is also known to rapidly develop pesticide resistance.
The APVMA has issued a number of permits for the use of certain chemicals for the control of fall armyworm. More information on minor use permits for use on fall armyworm is available on this page.
Through the Plant Biosecurity Research Initiative, an educational podcast series for growers has been developed to assist industry in managing fall armyworm.
The series is available from the Plant Biosecurity Research Initiative website and will come to include five episodes featuring interviews with international experts on their experiences with the pest; two episodes with Australian scientists on current advice and knowledge gaps; and four episodes with growers and advisors discussing regional topics and responses.
This project is a collaboration between Hort Innovation and other research and development corporations including the Cotton Research & Development Corporation, Grains Research & Development Corporation, Sugar Research Australia and AgriFutures Australia.
A Fall armyworm conference is being organized by the Department for Agricultural Research, to bring together researchers from around the world working on Fall Armyworm (FAW) pest management to present their latest findings.
The programme is organised into eight plenary sessions, each covering a different topic related to the development of Integrated Pest Management (IPM) for FAW and chaired by an expert in the field. These sessions will comprise a series of oral presentations of original research followed by an extended Q&A.
The conference runs for the 24 to 26 August and is free to register. To get more information and to register visit the CIFOR-ICRAF website.
The Queensland Department of Agriculture and Fisheries (DAF) has developed range of resources:
A question and answer (QA) sheet has been produced by DAF that provides a lot more information and actions you should and can take to prevent and manage fall armyworm. The QA sheet is available at the DAF website or by download here.
Hort Innovation is keeping a close eye on the situation and is currently working with the relevant authorities to prepare and protect the horticulture sector against any potential spread of fall armyworm.
This includes, but is not limited to:
Hort Innovation investments:
MT19013: Podcast for fall armyworm management in Northern farming systems. This multi-industry and cross-sector project was established to support readiness and help protect the horticulture sector from fall armyworm, through the delivery of an educational podcast series for growers. Access the series from the Plant Biosecurity Research Initiative website.
MT19014: Field-based testing for fall armyworm. This project builds on previous developments of a rapid, in-field molecular test for early detection and identification of fall armyworm. This short investment will conduct the second phase of this research to monitor the movement of fall armyworm through quick and accurate testing conditions.
MT19015: Identifying potential parasitoids of the fall armyworm, Spodoptera frugiperda, and the risk to Australian horticulture. This project will deliver extension materials to growers on how to effectively manage fallarmyworm. The research team will identify potential parasitoids and predators of fall armyworm to improve management strategies and recommendations on control of the pest.
VG20003: Co-developing and extending integrated Spodoptera frugiperda (fall armyworm) management systems for the Australian vegetable industry. Through this investment, the vegetable industry will work closely with researchers to identify management gaps and trial a range of strategies on-farm. Outcomes from these trials will be shared with the Australian vegetable industry and will inform future fall armyworm research investments.
Hort Innovation has been successful in securing emergency minor use permits from the Australian Pesticides and Veterinary Medicines Authority (APVMA) for use on fall armyworm. Please see details below:

Plant Health Australia have also secured a permit for fall armyworm that includes sweetcorn that you can access on the APVMA website here.
All efforts have been made to provide the most current, complete and accurate information on these permits, however you should always confirm all details on the APVMA website at https://portal.apvma.gov.au/permits. Details of the conditions of use associated with these permits can also be found on the APVMA site.
You can also access the Non-Performance Reporting Form for Horticultural Pesticides here. This form should be completed when an adverse experience occurs as a result of using a permit. A 'non-performance' is an unintended or unexpected effect on plants, plant products, animals, human beings or the environment, including injury, sensitivity reactions or lack of efficacy associated with the use of an agricultural chemical product(s) when used according to label (or permit) directions.
Users are advised that while the pesticide can be applied legally under the APVMA minor use permit, there can be a significant delay until the MRL gazetted by the APVMA is adopted in the Australia New Zealand Food Standards Code. Until this occurs the MRL may not be recognised and a zero tolerance may be imposed for residues of the pesticide resulting from its use according to the APVMA permit.
Please be aware that in the absence of an MRL in the Food Standards Code, the use of the pesticide according to the permit may result in the suspension of the produce in the marketplace. Please check the FSANZ website or the Australian Government ComLaw website (https://www.legislation.gov.au/Series/F2015L00468) to confirm if there are MRL established by the Australia New Zealand Food Standards Code.
