The locust population remains generally low in much of inland eastern Australia but parts of the North West, Central West and Far West regions of NSW currently have moderate to high nymph presence in some areas. The Moree area in particular is reporting small numbers of bands of nymphs between 1-20ha in size with a few being up to 100ha. Hatching and banding locusts are expected after the low to medium number of adults across the north and west of the state in November and December 2020.
Favourable seasonal conditions in most areas will assist with rapid nymph development. Further generations hatching and developing will put late summer and early winter crops at risk as well as impacting pastures. Landholders are encouraged to inspect their lands, report locusts and undertake control in order to reduce the development of large swarms in autumn and the following spring.
North Eastern, South Eastern and parts of Western NSW received higher than average rainfall totals in December. Elsewhere December rainfall was close to or slightly below the December average. The official climate outlook indicates moderate to high probabilities of above median rainfall across NSW in the February to April period.
This means there is a high probability of locust breeding within favourable habitats. Under suitable weather systems, redistributions and aggregations are possible and thus swarms are likely to appear in many areas from now into autumn 2021.
Landholders and Local Lands Services staff will continue to monitor these areas over the coming months.
Landholders that suspect or are aware of any locust activity on their land should contact their Local Lands Services office on 1300 795 299.
Landholders are responsible for reporting locusts and the control of locusts on their land. If locust populations reach agreed treatment criteria, Local Lands Services will supply ratepayers with chemical to treat locusts.
