Think twice before you swat, stomp, curse or ignore insects, says Cornell University entomologist John Losey. His research, published in the current issue of the journal "BioScience" shows that the dollar value of just four services provided by insects is worth more than $57 billion in the United States each year.
"Most insects tirelessly perform functions that improve our environment and lives in ways that scientists are only beginning to understand," Losey says. "Don't let the insects' small stature fool you - these minute marvels provide valuable services."
The study found that native insects are food for wildlife that supports a $50 billion recreation industry, provide more than $4.5 billion in pest control, pollinate $3 billion in crops and clean up grazing lands, which saves ranchers some $380 million a year. And these are "very conservative" estimates that probably represent only a fraction of the true value, says Losey, associate professor of entomology at Cornell.
Losey co-authored the study with Mace Vaughan, a Cornell graduate, who now serves as conservation director of the Xerces Society for Invertebrate Conservation in Portland, Oregon. The Xerces Society works to protect native insect habitats through education and research.
Insects are an integral part of a complex web of interactions that helps put food on our tables and remove our wastes. Humans, and probably most life on Earth, would perish without insects, Vaughan said.
"We know how to repair roads and other components of our physical infrastructure, but our biological infrastructure is vulnerable to degradation too," said Losey, an applied insect ecologist. "If we do not take care of it, it will break down and could seriously impact the economy." "In fact in many places - crop pollination, for example - the cracks in the infrastructure are already showing," says Vaughn.
Using published data, the scientists compared the values of each service at current levels of function to theoretical levels if these serves were absent. The analysis did not include such insect services as decomposing carcasses, garbage and trees - thereby decreasing the likelihood of forest fires. Also omitted from the study were the insect functions of producing honey, shellac, dyes and other products.
