What is HopperWiki?

HopperWiki is an early-stage project designed to serve as a global repository of information for all Orthoptera. The project, led by the Global Locust Initiative at Arizona State University, brings together experts from diverse fields to create original content and facilitate access to the wealth of existing resources on the world’s ~30,000 described species of orthopteran insects. In addition to species profiles which are built on the foundational taxonomic database of the Orthoptera Species File, HopperWiki aims to enhance the accessibility of researchers and organizations working on Orthoptera. A key focus is compiling resources that address the complex challenges of sustainably managing locusts and pest grasshoppers, which have significant impacts on human livelihoods and the environment.

Featured person

Hector Medina is the Coordinator of the National Grasshopper and Locust Program at the National Food Safety and Quality Service (SENASA) in Argentina. He brings over 25 years of experience to the field. His expertise lies in locust and grasshopper monitoring, control strategies, and early warning systems. He actively develops policies to prevent and mitigate locust outbreaks and has contributed significantly to national and international meetings, workshops, and training programs associated with locust management. Hector has also played a crucial role in shaping guidelines and manuals for effective locust control.

Featured resource

This handbook provides a comprehensive guide to the grasshoppers of New Mexico, covering their morphology, life cycles, behavior, population dynamics, and distribution. It explores historical and ecological aspects of grasshopper management, including biological and chemical control methods, population estimation, and cooperative control programs. The book also includes identification keys for various grasshopper families and subfamilies, along with an annotated species list, making it a valuable resource for researchers, land managers, and entomologists.

Featured species

The migratory grasshopper (Melanoplus sanguinipes), is a spur-throated grasshopper widespread across North America, particularly in central and western regions. It is thought to be a close relative of the extinct Rocky Mountain locust (Melanoplus spretus) that swarmed the Great Plains in the 1800's. M. sanguinipes is a medium to large grasshoppers and is considered one of the most abundant and destructive pests to rangeland and agriculture in the North American West. It is a generalist feeder and thrives in degraded or weedy landscapes. They are known for their ability to migrate in swarms, especially during outbreaks. The economic impact of their outbreaks along with other species leads to the treatment of millions of acres of range and cropland each year. Click here for more details.
