In nearly a century of living and studying living things, Wilson has undoubtedly seen more ants than the busiest professional bug exterminator. Placing the words ants <\/i>and exterminator<\/i> together in a sentence in an article about Wilson could strike a nerve among people with an affinity for ants. As a man who has studied ants for most of his life, it\u2019s not surprising that one of the most common questions Wilson gets asked by people is what to do about the ants that crawl into their houses. Spray? No way!<\/p>\r\n

\u201cThey are missing some of the wonders of nature,\u201d Wilson insisted. \u201cI love having a colony of ants in my kitchen. What I do is I give them something to eat [like]<\/em> cookie crumbs.\u201d<\/p>\r\n

Once, a colony took up residence near Wilson\u2019s kitchen sink. \u201cThey would come out of a crack in the base of the edge of the sink. Instead of spraying them or squishing them, I would put food out for them and watch,\u201d he said. \u201cThe scout would come out and smell and then he would eat a little bit and then he would [get] <\/i>all excited. It would go running back, laying a little trail and, in a few minutes, out would come a whole bunch of ants out along the trail. I enjoyed having a pet colony. I recommend it.\u201d<\/span><\/p>\r\n

As a teenager, Wilson reported the first known colony of imported red fire ants in his home state of Alabama. Later, he studied the warrior-like Matabele ants in Africa, the critically endangered Aneuretus simoni <\/i>in Sri Lanka, and thousands of other species. Several of his 32 books focus on the ant world, including The Ants<\/i> [coauthored with Bert H\u00f6lldobler],<\/i> which won a Pulitzer Prize, and his only work of fiction, Anthill: A Novel<\/i>.<\/span><\/p>\r\n

In the late 1950s, Wilson made what he considers his single most important discovery: pinpointing which gland in ants gives them the ability to communicate with each other.<\/p>\r\n

\u201cWhen I made it, I couldn\u2019t sleep that night\u2014that kind of a discovery,\u201d Wilson recalled. \u201cI knew that ants communicate, not by touch\u2014there isn\u2019t any signaling something\u2014not by any sound\u2014but by chemicals\u2014pheromones, that is, odors that they would release, substances they would spread from a gland that would give a message to other ants. That was only vaguely thought when I decided to check this all out and see if I could break the pheromone code.\u201d<\/span><\/p>\r\n

Using fire ants for his experiment, Wilson tested different glands with no luck until he extracted the Dufour\u2019s gland at the base of the sting.<\/span><\/p>\r\n

\u201cI had noticed when the fire ants find food and return home they stuck out their sting and were dragging their sting,\u201d he said. \u201c[Dufour\u2019s]<\/i> was a little teensy gland that took really a lot of effort to dissect out. But when I took it out and made an artificial trail with it, I could lead fire ants anywhere I wanted.\u201d<\/span><\/p>\r\n

It was an amazing sight to the young entomologist. \u201cThe fire ant would discover food, come running back, laying a trail, rush into the nest, and then rush up to other fire ants\u2014almost like grabbing them by the shoulder and shaking them and saying \u201cFood, food, I found food! The ants smell the trail and get on the trail, and they run back.\u201d<\/span><\/p>\r\n

Right now, Wilson\u2019s research focus is on ecosystems. Little research has been done on them. But their importance is inescapable. [Read the accompanying article \u201cThe Half-Earth(ling)<\/a>\" to learn more about Wilson's Half-Earth Project.]<\/i><\/p>\r\n

Much more data on plant and animal species needs to be collected, both by scientists and citizen scientist volunteers, according to Wilson. He recently celebrated his 90th birthday by participating with taxonomic specialists, students, families, and other community members in the Great Walden BioBlitz at Walden Woods in Massachusetts. Wilson made a special point of spending time with a group of children collecting samples of organisms, including ants. <\/span><\/p>\r\n

Wilson likes to use the example of the ecosystem of the sea otter, which was hunted to near extinction on the Pacific Coast by the early 1900s. When the sea otter population fell, the kelp forests along the coast disappeared too. That threw an entire ecosystem off kilter.<\/p>\r\n

\u201cThe kelp forest of seaweed and algae along the coast declined and, in places, disappeared,\u201d Wilson said. \u201cWhat had happened? The sea otter fed upon sea urchins that live in kelp forests. The sea otter was the [urchins\u2019]<\/i> main predator. The sea urchins exploded in population. They did not have their predator that kept them in control. There were so many of them that they ate the kelp. When sea otters were allowed to come back\u2014hunting was forbidden\u2014then the sea otters reduced the numbers [of sea urchins]<\/i>, and now the kelp is coming back.\u201d<\/span><\/p>\r\n

Wilson said not much is known about ecosystems, but he hopes to change that. \u201cWhat I am doing right now is to begin systematic studies, deep studies, mathematical studies of ecosystems,\u201d he said. \u201cIt\u2019s so complex; nobody understands them.\u201d<\/p>\r\n

He wants to find out how ecosystems are formed, how they evolve, and then how they equilibrate. \u201cA pine forest has been there for a thousand years. How did [the trees]<\/i> come to a point where they don\u2019t change much?\u201d he asked.<\/p>\r\n

It\u2019s a tall order, but Wilson is never one to slow down. \u201cI\u2019m 90 now, so I\u2019ve got to get this done before I pass on to that great rain forest in the sky,\u201d he said with a smile.<\/p>"}],"references":null},"yoast_head":"\nHe Pays Attention to the Little Things That Run the World<\/title>\n<meta name=\"description\" content=\"25 years after his first appearance at the Esri User Conference, renown entomologist Edward O.
