Resource description
A comprehensive identification resource authored by Thomas Valente and published in April 2024 by the Oregon Department of Agriculture. This guide is designed to assist in the identification of the major pest grasshopper species in Oregon, particularly those that have historically reached outbreak levels and caused damage to rangeland and agricultural crops. It provides detailed species accounts for nine key grasshoppers, including Ageneotettix deorum, Aulocara elliotti, Camnula pellucida, and several Melanoplus species, offering descriptions of both nymphal and adult stages. The guide includes a pictorial key for identifying immature grasshoppers, high-quality photographs illustrating morphological features and developmental stages, and information on survey methodologies used to monitor grasshopper populations. Additionally, it presents historical outbreak data and a checklist of Acrididae species documented in Oregon. Developed in cooperation with the USDA Animal and Plant Health Inspection Service, this field guide serves as a valuable tool for entomologists, land managers, and agricultural professionals engaged in grasshopper monitoring and management.
