The mosquito can also carry dengue, a painful disease better known in tropical countries that has made appearances in Key West over the past decade, including one case in The third of MosquitoMate's saboteur insects, Ae. The bacterial infection technique that finally worked was simple in concept, though not so simple to execute, says entomologist Stephen Dobson at the University of Kentucky in Lexington. Larvae can grow in mere bottle-capfuls of rainwater, so saucers under potted plants or puddles in a crumpled tarp can become a public health menace. Wolbachia-carrying males have no problem siring bouncing baby mosquitoes if the mom also carries the bacterium, and the young then carry the bacteria, too.
Blowing gently at one end of the tubes encouraged males to lift into the air and whine off in search of the island's wild females. Keys' residents would love to see a big drop in the mosquito's numbers, too, but Leal says that's the next stage. After a long hunt, Dr Roelofs and his team found the relevant gland, right at the tip of the female cockroach's abdomen. Wolbachia compete with viruses for precious resources inside cells, such as cholesterol. Instead of suppressing mosquitoes and risking a comeback, he chose an approach that relies on the bacteria to spread and maintain themselves. With mosquitoes doing the work, "we can sort of march across the landscape," O'Neill says. It is all very well having an insect trap, but you need an effective bait. After the California test, the group made some tweaks in hopes of creating at least a 7-to-1 ratio of bacteria-carrying Kentucky males to native Floridian rivals. Over time, flooding a neighborhood with bad dads should shrink the local population of Ae. Now they have, Science magazine reports, and they hope to develop a special trap using the pheromone. The first salvo in this new battle began on the afternoon of April 18, when staff of the Florida Keys Mosquito Control District worked their way along some streets on Stock Island. That's the initial result that Leal, of the mosquito control district, is focusing on for this year. One advantage of the test's population-crashing approach, says Dobson, also MosquitoMate's CEO, is that workers puffing a thousand insects out of a shipping tube near someone's yard are releasing only males, which don't bite. One of the project's first release sites, in Australia, still hums with Wolbachia-carriers six years later with no need for additional treatment. The project could release mosquitoes with a new combination of Wolbachia strains to spread through a population and replace ones that are losing effectiveness. O'Neill hasn't seen signs of resistance yet, but he has a plan if he does: Eliminate Dengue is marching over swaths of five countries, including Brazil. The bacterial infection technique that finally worked was simple in concept, though not so simple to execute, says entomologist Stephen Dobson at the University of Kentucky in Lexington. Wolbachia-carrying males have no problem siring bouncing baby mosquitoes if the mom also carries the bacterium, and the young then carry the bacteria, too. The approach now being tried in Florida would instead try to stomp down their numbers. To replace the mosquito population with a safer one — the better-known strategy — requires releasing females, too, which Dobson points out, "bite people and drink their blood. Larvae can grow in mere bottle-capfuls of rainwater, so saucers under potted plants or puddles in a crumpled tarp can become a public health menace. Now all they need to do is design a clever trap. The bacterial infection can sweep into a population extraordinarily fast. The Eliminate Dengue team has already developed mosquitoes infected with just such a combination of bacterial strains , he says. Scientists were able to infect mosquitoes with the bacteria without genetically modifying either species, a plus because a recent proposal to release genetically modified mosquitoes as pest control in nearby Key Haven stirred fierce protests SN Online:
