SILVEIRAS, Brazil � Jorge da Silva plucked a giant ant from the muddy ground, pulled off its wings, legs and mandible, and tossed it into his mouth like popcorn. The i��s are an obsession for the 6,000 people in Silveiras. "Tastes like mint," said Mr. da Silva, 58, with an audible crunch of his teeth. In his rubber boots, Mr. da Silva roamed the hills above this town of 6,000 people with a stick and a plastic bucket. He was on the hunt for Silveiras�s obsession and a rare gastronomic delicacy in Brazil: i��s, or queen ants. The thunderous spring rains in October and November drive the ants out of the ground, and for a few short weeks Silveiras becomes a frenzy of ant hunting. Residents stock up, cleaning the i��s and freezing them in one and two-liter bottles to get through until the next season. But this year the ant haul was smaller than usual, residents said, and the number of ants has been dwindling. The principal culprits are pesticides used on eucalyptus trees that are planted to produce cellulose for paper and other products, residents and local officials said. "With urbanization and the poison that they are putting into the soil, we do not have much time left," said Vera Toledo, 67, a writer and anthropologist whose husband is a native of Silveiras. Generations of indigenous people treated the ants as a protein substitute for fish and monkeys, residents said. Today, Silveiras residents � and the people who drive hundreds of miles every year to buy the ants � value them not only for their protein, but also as an aphrodisiac and source of natural antibiotics. Residents of this town 190 miles from S�o Paulo have kept alive the ancient indigenous tradition by cooking and serving the ants with traditional Brazilian dishes. These are no ordinary ants scampering over sugary leftovers, like the tiny American variety. I��s are big � up to an inch in length � and fat, and they can bite viciously. But the changing landscape means the ants are under threat, residents contend. Driven by Brazil�s growing economy, the eucalyptus trees have proved to be a big boon for some landowners in Silveiras, which has lost its place as a major coffee and cattle producer and once had a population of more than 30,000. Residents have not tried to make the ants into a big commercial enterprise. In northern Colombia, locals are exporting their "hormigas culonas" or big-rear queen ants, to France, Britain and other countries, where they are dipped in chocolate. The giant leaf-cutter ants in Brazil come from the same Atta family as the Colombian species, said Marina Saiki, a biologist at the S�o Paulo Zoo. But while residents here say they could certainly use the extra money, many seem more concerned with preserving the tradition � and the ant population � for themselves. Oc�lio Ferraz, Silveiras�s resident i��s guru, has dedicated himself to keeping the ant feast alive. A self-professed environmentalist, he has resisted efforts to export them, preferring to receive visitors at his restaurant, where he has a special kitchen devoted to frying the i��s. Mr. Ferraz, 72, says he receives almost daily phone calls asking him to start delivering ants to far-off towns. He said he looked into exporting them at some point but gave up because the Brazilian export laws for food are too complicated. Beyond that, he said, "I don�t think making deliveries would be good for the quality of the tradition." He grew up eating i��s at home and taught the tradition to his children. Then, 20 years ago, he held an i�� festival that drew more than 400 people. The festival�s success inspired him to create an arts and crafts center dedicated to the tradition. Today he shows off table mats, dishes, cups, his apron and paintings on a wall of his restaurant that all feature the queen ant. Other artists are designing toys. Slowly, Mr. Ferraz was able to help break the stigma that used to surround eating i��s, which had been seen as a tradition reserved for poorer families. "Many people would say they were embarrassed about eating i��s," he said. And yet, he said, every October and November "the entire town would smell like frying ants." Today the residents are more open about their appreciation for the crunchy queen ants. I am an i�� fanatic," said Mar�a Jos� Camargo, 29, as she sampled some ants at Mr. Ferraz�s restaurant. "I love it so much. It�s worth saving money all year to spend on i��s. My children are too young to catch them, but when they are grown they will catch i��s for sure." The içás are an obsession for the 6,000 people in Silveiras. Back in the hills, Mr. da Silva, the ant hunter, is teaching 12-year-old Dudu da Silva, no relation, how to capture the ants. With his bare fingers, Mr. da Silva grabbed the i��s one by one and tossed them into the bucket. Thump. Thump. Thump. The ants frequently bit Mr. da Silva, whose hands are typically bloodied after a day of catching them. At one point, a little girl watching him work cried out in pain as an ant bit her foot. Back at Mr. Ferraz�s restaurant, the ant catchers sell their haul for an average of about $15 per liter. He charges about $12 for a large plate of i��s with wheat fried in pig fat meant for two. While the ants sell fast and are a seeming source of pride, some Silveiras families are divided over the practice. Edson Mendes Mota, the former mayor of Silveiras and now its development director, said he does not care for them, even though his wife has 17 pounds of i��s in their freezer. "My wife likes it, my kids like it, the whole town likes it," he said. Mr. Mota supports the town�s growing eucalyptus industry, which has become the enemy of the ants. Landowners have a right to plant the highly profitable trees, though the plantings need to be regulated, he said. "We need to unite and sit down and discuss the fact that the new generation here will no longer know the traditions of our town," Mr. Mota said. Alair Duarte, the president of the town council, said he had proposed limiting eucalyptus plantings to certain areas so the ants can continue to reproduce. "If we don�t do it soon, we won�t have any i��s left," he said. "Before we can think about exporting i��s we need to preserve what we have here," said Mr. Duarte, who grew up eating the queen ants raw. If the i��s are imperiled here, some residents say they believe there is still a place where the eucalyptus plantings are not killing off the ants. "People say there are a lot of i��s in the cemeteries because they eat people�s brains," said Osmar da Silva, 43, an i�� salesman. "But it�s a legend," he said, though he admitted "I have never had the courage to go into a cemetery and actually look there."

If it will protect my rose's from looking like crap in 125F heat I am willing to try it. I don't get to enjoy my rose's in the summer in the Arizona desert my growing season is when most of you are buired under the snow. I dread summers but have to stay her until hubby retires. I am willing to try a product that claim's it will stop the stress my rose's are under in Jul, Aug & Sept. I will not build a cover in my front yard that I have to take down in the winter and apply and pay for a building permit with my city hall. A product I can spray would be easier and less expensive. If I lived in Zones 5,6,7 & 8 I would poo poo this product too but when one struggles with 125F in the hot Az. heat you try anything to stop the roses from being under so much stress. I have tried tons of organic products to help with summer stress to no avail. I am always on the look out for products that are somewhat sold at a reasonable price( I would only need the 16oz size).If you lived here and put up with the ugly leaves, the proliferated blooms you would be looking for new products to stop that too, and they get plenty of water and mulch, I do not feed them in the summer because of burn. I think I will try it, unless someone here has a better idea then building a structure in my front yard. Carrie

OK, I surrender :) The insecticide pyrethrins, under discussion, is contained in many products with different brand names. For example, you could check labels of "house and garden" aerosols that are sold in supermarkets. Aerosol might be convenient for you. The ingredients are pyrethrins + pepironyl butoxide. Be sure it is labeled for use on plants. This insecticide kills most bugs (good or bad) on contact, but has no residual effect. This means you must reach each insect with the spray. It is considered relatively safe for mammals. Another low-risk insecticide is spinosad. It is residual but has less effect on beneficial insects. Google the term for brand names. Fertilome, Monterrey, and Gardens Alive are some producers. You want the active ingredient spinosad. It will kill rose slugs. You need a tank sprayer to apply it. Use insecticides only on plants where there is active damage going on.

Your garden will show some effects.....even rinsing won't remove all of the herbicide and some succeptable plants will suffer. You will see twisted and odd shaped leaves and some plants may well die. BUT you may not see those effects....it depends on what herbicide you used....24D? 245T...trimec? But there is nothing to be done.....but I will bet you will never make that mistake again!!! OK...here comes the lecture! Quit using the chemical fertilizers on your garden and go with compost and composted manure, a bit of alfalfa pellets, some blood meal and that's pretty much all. I am not so organic minded that I don't use big guns when it comes to weeds and grass where it shouldn't be....but once I realized how much better my gardens were with just leaves, wood chips and composted manure....I have not touched that miracal grow sprayer.....and with only one sprayer, there's no chance of a similar error.
