For information on currently registered and or permitted insecticides to manage FAW, check the Australian Pesticide and Veterinary Medicine Authority (APVMA) website.īeneficial insects can be prevented from becoming effective at reducing pest populations if broad spectrum insecticides are used in the production system. The use of chemical control is an option where economic damage can be prevented. Economic thresholds for control are an area of current research.
Issues such as whether FAW will persist through winter in Victoria, or migrate seasonally from warmer northern states, will influence control strategies.
Melinda Miles, Queensland Department of AgricultureįAW development and behaviour in the Victorian climate is not known to date.NSW Department of Primary Industries – Fall armyworm.For more information about FAW in Australia please take the time to look at the experience of monitoring and managing FAW from other states and industry perspectives. Report any sightings of FAW to Agriculture Victoria on 136 186 or complete the Agriculture Victoria online reporting form. Look for egg masses, plant leaf damage and fruit or vegetable damage. It is not yet known if FAW will be able to establish in Victoria. Given the ability of FAW to travel long distances, there is potential for incursions into Victoria from the northern states, most likely during warmer months (summer/autumn). It is not yet known if FAW will be able to persist over winter Yes, FAW is considered present in Victoria.įAW generally prefers tropical and subtropical climates, which does not match the climate of Victoria’s production regions. It is now considered established in Australia.ĭespite multiple attempts, FAW has never been successfully eradicated from any country it has invaded. In December 2020 FAW was found at a single location in East Gippsland in Victoria. In January 2020 it was detected in far north Queensland and has since been found in northern Western Australia and the Northern Territory. In September 2020, it was detected in a FAW surveillance trap near Moree in northern New South Wales. Since 2016 FAW has spread quickly through Africa, the Indian subcontinent, China and south-east Asia. Left unchecked, numbers can increase quickly due to abundance of suitable host plants, fast reproductive cycle and ability to disperse long distances.ĭestruction of crops can happen almost overnight when population levels are high.
Fall armyworm is a highly invasive pest that has recently become established in Australia.įall armyworm (FAW), Spodoptera frugiperda, is a highly invasive and destructive caterpillar native to tropical and subtropical regions of the Americas.
