Plague locust situation
Locust swarms have recently been reported in the Central West authority, particularly in the Coonamble and Trangie areas.
The outlook is for more swarms to form in the Coonamble–Gulargambone–Baradine, Quambone–Warren, Nyngan–Tottenham and Tullamore–Peak Hill areas during November. Migration of young adults from central west NSW to other regions is possible during November and these could form swarms in some areas. There were reports of laying in the Coonamble-Gulargambone area and these are forecast to hatch in late November and early December.
Landholders should check their properties for locust activity including adult swarms, nymphal bands, hatchings and egg beds.
Livestock Health and Pest Authorities are working closely with Industry & Investment NSW (I&I NSW), the NSW Farmers Association, the Australian Plague Locust Commission (APLC) and landholders in a coordinated approach to controlling locusts in NSW.
Under the Rural Lands Protection Act 1998, landholders are required to report the presence of plague locusts on their land to their local Livestock Health and Pest Authority. They are also required to use insecticide to control locust nymphs when the nymphs band together. Insecticide is provided free of charge from local LHPAs provided locust activity meets certain criteria.
It is important to contain the outbreak at the nymphal stage using ground control to prevent the locusts from migrating, breeding and laying more eggs.
Monitoring
Livestock Health and Pest Authority staff are collating locust reports from landholders, carrying out on-ground inspections and mapping locust activity.
It is essential that landholders report any locust activity immediately to their local Livestock Health and Pest Authority office.
Role of landholders
Landholders have a responsibility under the Rural Lands Protection Act 1998 to report the presence of plague locusts to their Livestock Health and Pest Authority and to control locusts/nymphs on their land, using insecticide provided from the Livestock Health and Pest Authorities. The stocks of insecticide are funded from the Pest Insect Levy paid by all Livestock Health and Pest Authority ratepayers in NSW.
It is vital that landholders cooperate and:
- Report all infestations to their local Livestock Health and Pest Authority office.
- Control locust bands on their land by treating them with insecticide.
Control methods
Ground control by landholders when the nymph form of the locusts band together provides the most effective opportunity to control locusts.
To report locust activity contact your Livestock Health and Pest Authority office.
