A locust laying eggs.

LOCUST activity in central west New South Wales is prompting new on-farm inspections by authorities and a call for vigilance by landholders.

Central West Local Land Services suspected reported adult swarm activity might be the result of migration on recent storm fronts.

This has kept CWLLS busy on the ground with confirmed inspections of activity in the Trundle, Leadville and Weetaliba areas. Further inspections were planned for the Mendooran, Purlewaugh, Albert and Trangie areas.

The CWLLS is still encouraging landholders to remain vigilant in reporting any activity. This is a quick and easy process which proves invaluable to all affected by locusts, it said.

There are still reports of nymph activity coming in and landholders are being reminded that this is the best time for control. Once the locusts are flying, effective control becomes very difficult and expensive.

Inspections have discovered egg development on some adults, which means monitoring for any egg beds is essential, especially over the coming weeks. Current environmental conditions would likely see any eggs laid by early December, set to hatch around Christmas.

If you would like to report any locust activity, contact your nearest Local Land Services office on 1300 795 299 or complete the online form available on our website www.centralwest.lls.nsw.gov.au
