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

oppers on federal rangeland. Previously, the agency sprayed large swaths of land with insecticides, including areas where grasshoppers were actually befitting plant growth by speeding up nitrogen recycling. USDA/APHIS now relies on more restricted spraying, focusing on those areas where grasshoppers are damaging plants.

Belovsky also used National Science Foundation funding to develop mathematical models to help predict significant spikes in grasshopper populations based on the number of grasshopper eggs. If egg numbers are low in the spring, grasshopper predators like birds and spiders can usually keep the populations under control. However, when eggs in the spring are especially numerous, more grasshoppers hatch and predators are unable to keep the populations under control, which can signal significant problems for rangeland ecosystems. However, if grasshoppers are very abundant, the young grasshoppers may actually compete for the rarer highly nutritious food plants and starve to death before they can grow up and cause damage to the range.

Belovsky's research is now the longest running experimental study at a site examining what controls grasshopper numbers and, as such, Belovsky continues to acquire an unusually detailed and rich database of scientific information about Western rangelands. Additionally, UNDERC undergraduates, including a number of Native Americans, learn about this striking ecosystem and some participate in the research.

His research has the potential to make grasshopper plagues, like the Rocky Mountain locust, but a memory.
