In NSW Spring surveys by Australian Plague Locust Commission staff identified low density adults in most regions. The outlook for summer is for population densities to remain generally low in all regions of inland eastern Australia. Localised breeding is likely to occur in habitat areas that receive heavy rainfall in December and this will result in small regional population increases. NSW Department of Primary Industries (NSW DPI) and Local Land Services (LLS) continue to plan and prepare for any potential plague locust control program.
Australian Plague Locust: The outlook for the rest of summer 2018/19 is for population densities to remain generally low in inland eastern Australia. Small population increases are likely in localised areas of favourable habitat. The Bureau of Meteorology seasonal rainfall outlook for January to March 2019 indicates continued below average rainfall and high temperatures over most of the species range. However, localised heavy rainfall events can provide breeding opportunities resulting in subsequent nymph populations. Given the very low current population numbers in all surveyed regions, there is a low probability of successful breeding producing high density populations during January or February.
Spur-throated Locust: No locusts have been recorded in NSW and no nymphs have been detected by surveys. There is a low risk of a widespread infestation developing during 2018-19.
Migratory Locust: Surveys in December did not detect this species in NSW. There is a low risk of a widespread infestation developing during summer 2018/19.
