Big Apple's Insects Eat Streets Clean

Researchers working in New York City found that hungry urban arthropods help dispose of tons of edible trash. Allie Wilkinson reports

Rather than cringing at 畏縮the next beetle甲蟲or wasp黃蜂 in your way擋在你的面前, you might want to thank them—for helping to keep city streets clean.

Researchers from North Carolina State University working in New York City found that hungry urban
arthropods節肢動物 play a significant role in the disposal of trash垃圾處理. For example, in a small section of Manhattan called the Broadway/West Street corridor通道/迴廊, insects consume the equivalent等同/相當於 of 60,000 hot dogs a year that would otherwise be lying in the street. And that’s assuming the bugs stop chowing down in winter.

To assess how much
discarded丟棄 food bugs got rid of, the researchers placed measured amounts of hot dogs, potato chips and cookies at 21 park sites and 24 street medians道路中央地帶(如分隔島). Contrary to their prediction與他們的預測相反, location played an even bigger role in garbage consumption than biodiversity 多元生態did—insects gobbled up 狼吞虎嚥地吃下去 two to three times more food in the street medians than they did in the parks.

The study appears in the journal Global Change Biology.


If all that garbage disposal still does not make you an arthropod admirer, then consider this: by competing with larger pests for resources, insects help keep rat populations down. There’s some food for thought.值得深思的
