" The old adage says dog is man&amp;#039;s best friend, but Cornell University entomologist John Losey begs to differ. Insects, he says, provide far more valuable services.  In the first analysis of its kind, a study Losey co-authored in the journal BioScience estimated the economic value of various jobs the six-legged creatures routinely perform. It found that 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.  The analysis did not include such important insect services as decomposing carcasses, garbage and trees (thereby decreasing the likelihood of forest fires); producing honey, shellac, dyes and other products; being used in medicine or as a source of food for animals other than those used in hunting, fishing and birding; and providing a direct source of food for humans. According to Losey, insects improve our lives\u2014and our economy\u2014in ways that scientists are still just beginning to understand. \u2014J.Bogo  If dung beetles did not clean cattle environments, it would deter cattle from eating the plants and attract more flies and parasites that would then have to be controlled.
