Locusts

2013/14 Locust Season

The Australian Plague Locust is likely to have a low to moderate activity level this season, with widespread low density nymphs in parts of the Central West, Riverina, Far West and Far Southwest regions of NSW and high density nymphs in localised areas. The risk of widespread infestations is low but landholders are urged to actively monitor their properties and immediately report locust egg beds, nymphs or adults to their Local Land Services (LLS).

Present indications are that some localised ground control may be required by landholders. Landholders are responsible for the control of locusts on their land. If locust populations reach agreed treatment criteria, LLS will supply ratepayers with insecticide to treat locusts.

Department of Primary Industries (DPI), along with LLS, will advise if any significant locust activity develops.

There is a low risk of significant or widespread populations of the Spur-throated Locust and Migratory Locust in NSW.

Widespread rain during February and March 2014 resulted in moderate overall increases in adult population levels in all regions during April and further increased in May. In NSW, surveys of the Central West, Riverina, Far West and Far Southwest regions identified a moderate increase in adult numbers to medium densities during April whilst numbers remain low in the Northwest Plains regions. Low to medium density adults persisted through May and into June in some regions. The majority of eggs laid in March, April and May will mostly hatch together in spring.

Likely Hatching Date

Risk

Central West (Central West    and Central Tablelands LLS)

Sporadic laying likely around    Nyngan, Narromine, Tullamore and Condobolin districts

September

Moderate chance of low-medium    density nymphs developing during September and October with some small bands    developing in limited areas. There is a low risk of a significant infestation    developing during spring

Riverina (Riverina and Murray LLS)

Sporadic laying likely around    Narrandera, Oaklands, Rankin Springs and Urana districts

Late September and early    October

Moderate chance of medium    density nymphs developing in the Central Riverina region during October with    some small bands in the Lake     Cargelligo, Narrandera    and Jerilderie Area. There is a low risk of a significant infestation    developing during spring.

Northwest Slopes and Plains    (Northwest and Northern Tablelands LLS)

Very low levels

Late August

There is a low risk of    infestation developing during spring

Far     West (Western LLS)

Sporadic laying likely in the    Tibooburra, White Cliffs, Wilcannia and Broken Hill districts

Mid September (North) to late    September (South)

Moderate chance of low to    medium density nymphs developing in spring with small localised bands    developing in September. There is a low risk of a significant infestation    developing during spring.

Far Southwest (Western LLS)

Laying likely in the Broken    Hill and Ivanhoe Districts

Mid September

Localised medium and some    high density nymphs and some bands could develop in the Broken Hill, Menindee    or Ivanhoe areas during October with September hatchings likely to produce    low density nymphs. There is a low risk of a significant infestation    developing during spring.
