College Point now has eight mosquito traps designed specifically to trap Aedes Mosquitoes, the insects that can potentially carry the Zika virus. The traps were installed after concerns were raised about an excess of mosquitoes in College Point, where West Nile virus was first discovered in the United States (August 1999), and the potential danger of the Zika virus. source
Stagnant water, dark enclosures, carbon dioxide — different things attract different mosquitoes. From April to October each year, Vivek Raman, an environmental health supervisor with the Southern Nevada Health District, and his team sets hundreds of mosquito traps across Clark County to keep tabs on these pesky — sometimes even deadly — insects.
Last year, his team of five environmental health workers collected more than 26,000 mosquitoes. The mosquitoes are sorted and sent to the Nevada Department of Agriculture, which tests the insects for West Nile Virus, St. Louis Encephalitis and Western Equine Encephalitis. “Now Zika is on the radar, but it is one of many mosquito-borne diseases that we try to keep our eye on,” Raman said.
Maricopa County Vector Control is ahead of the game when it comes to trapping and potentially testing the mosquitoes that carry the Zika virus. James Will, a supervisor at Vector Control, said the agency has a few different traps that are designed specifically to attract the Aedes Aegypti. “The Aedes Aegypti mosquito can transmit Chikungunya, Dengue and Zika virus,” Will said.
Will said what attracts the Aedes Aegypti to them is scene and the color scheme; all the traps are black and white. “They just fly into the contrast and then there’s a fan and the motor in there that suck the mosquitoes into the net,” he said, describing one of the traps. Will admits some of the traps work better than others. “We were catching 300-400 in that one, and we’re catching 100, 100 or so in that one,” he said. Right now Vector Control can’t actually test for Zika but has to wait until the CDC develops and distributes a protocol.
Panama’s Gorgas Memorial Institute for Health, or ICGES, found in a recent study that genetically modified mosquitoes can be used to combat dengue with a high degree of effectiveness, scientists involved in the project said. Local residents “accepted and participated” in the study by placing “larvae-traps” and traps to catch mature mosquitoes in their homes in order to monitor the Aedes aegypti population.
Also taken into account was whether a declining Aedes aegypti population would increase the presence of other mosquito species like the aggressive Aedes albopictus, a concern expressed in a study by the British organization GeneWatch, but that, Caceres said, never happened.
However, the Panamanian scientist did not wish to claim that “this tool will eliminate or eradicate Aedes aegypti altogether.” “This tool must be used to complement other techniques and other strategies that exist to control Aedes aegypti in our country,” he said.
Nine mosquito traps in Gerlach, Nevada, a town near Black Rock Desert, have tested positive for West Nile virus. Sixty-five thousand people attended this year’s Burning Man Festival in Black Rock and could now be at risk of contracting the mosquito-borne disease.

Armed with buckets, odorous lures, nets and poison sprays, Columbus Public Health workers are prepared to take on the hordes of blood-sucking insects that can ruin summer for outdoors lovers. The agency hopes to outflank mosquitoes this year by increasing the number of traps across the city. Health workers will be trapping the insects at 81 locations this year, setting and collecting about 40 traps each week. Officials say they hope that setting the traps in permanent locations will help track trends in mosquito behavior better and determine where further action — such as spraying pesticides — is needed.
Although most mosquito species found in Ohio are merely an annoyance, the few that can transmit disease are worrisome. The Ohio Department of Health reported 24 human cases of West Nile virus last year and three deaths statewide. The agency also employs a few traps that use lights and dry ice (solid carbon dioxide) to lure mosquitoes. Both will trap Culex mosquitoes, which carry West Nile, said Joseph Conlon, a technical adviser for the American Mosquito Control Association. Read more
