Notre Dame research offers important clues about grasshopper population explosions
Date:2/25/2011

Literature and films have left us with vivid images of the grasshopper plagues that devastated the Great Plains in the 1870s. Although commonly referred to as grasshoppers, the infestations were actually by Rocky Mountain locusts.

The Rocky Mountain locust became extinct in 1902, but their cousins, grasshoppers and Mormon crickets, today still cause an estimated $1.5 billion (2005 U.S. dollars) in damage to grazing lands in the American West. A long-running research project directed by University of Notre Dame biologist Gary Belovsky, who also is director of the Notre Dame Environmental Research Center (UNDERC), is examining what limits grasshopper populations and the role played by grasshoppers in prairie ecosystems.

Belovsky first started studying grasshopper populations in 1978 at the National Bison Range, now a location for one of UNDERC's national undergraduate programs. Following the last major Western grasshopper outbreak in 1985, the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (UDSA-APHIS) asked Belovsky to help study the grasshopper's feeding preferences and population dynamics in western Montana.

Belovsky's research demonstrates that no single factor leads to a grasshopper outbreak, but, rather, multiple interacting factors are necessary. This requires sound understanding of how food and predators influence these native insects in combination with varying climate.

One of his key discoveries is that grasshoppers have a major impact on plants by changing the way nitrogen cycles in grasslands. Where grasshoppers speed up the process of nitrogen recycling by selectively feeding on plants that take longer to decompose, plant production increases. However, if they selectively feed on plants that decompose quickly, nitrogen becomes less available to the soil and plant production decreases.

Belovsky's findings helped change the way USDA/APHIS carries out its mandate to control grassh
