More than 13.5 million acres in western Nebraska are at high risk for serious grasshopper infestations this year, based on the 2010 fall adult grasshopper surveys conducted by the Animal Plant Health Inspection Service.
The number of adult grasshoppers last year is an indicator of the number of eggs laid in the fall, which is the overwintering stage of most grasshopper species.
Due to this potential threat, ranchers and landowners of rangeland in these high risk areas should be prepared to monitor the possible build-up of grasshoppers during the egg hatching period and early development periods of the most damaging species during May and June.
To address these concerns, a meeting will be held May 27 at the West Central Research and Extension Center in North Platte. It will begin at 1:30 p.m.
Speakers and topics are:
Matthew Masek, general forecaster, National Weather Service, "Summer 2011--a Climate Outlook"
Jerry Volesky, range and forage specialist, West Central Research & Extension Center,
"Balancing Forage Supply and Demand--including Grasshoppers"
Dave Boxler, Extension educator, entomology, West Central Research & Extension Center, "Grasshopper Biology, Control Strategies and Survey Updates"
