Summer’s Mosquito Fight Begins With Mosquito Traps

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

 

Mosquito Traps to Test for West Nile Virus

It’s that time of year again, time to watch out for those pesky mosquitoes. Already, some local communities are setting up traps to catch and test mosquitoes for the West Nile Virus. 

Mosquitoes are back and West Nile Virus Testing begins

The Bureau/Putnam County Health Department says it’s not too soon to be thinking about mosquitoes and West Nile Virus.  Kurt Kuchle, director of health protection for the two-county health department, said the health department has begun its surveillance program to detect possible West Nile Virus (WNV) activity in the local area. The surveillance program consists of testing mosquitoes collected from traps and also submitting dead birds for testing at the state lab.

The mosquito traps are placed each year in the vicinity of public access/gathering areas in both Bureau and Putnam counties. The health department has four traps, with typically three of those traps placed in Bureau County and one trap in Putnam County.  Read more

Mosquitoes have met their match

The 10th Medical Group Public Health office will be placing mosquito traps in areas throughout the U.S. Academy in Colorado.

The traps will be placed in “high-people traffic areas,” including base housing areas, the child development centers, installation gate entrances, Jacks Valley and other places throughout the Academy.
According to Senior Airman Anthony Arroyo, a public health technician here, the traps are not intended to get rid of the mosquitoes but to trap them for testing.

“The purpose of the traps is testing,” Arroyo said. “We want to ensure that the mosquitoes aren’t carrying harmful illnesses and diseases intended for humans.”

The trap most commonly used on base is the New Jersey Light Trap. The trap combines two types of attractions for the mosquitoes: CO2 and light. The trap emits CO2 and also has a small light attached that is powered by a small battery back. Mosquitoes are drawn to the light and a small fan attached to the trap pushes the mosquitoes into the net at the bottom of the trap. The traps will usually be placed in trees 6-8 feet off the ground with a battery pack placed in the tree. source

City of Dallas Prepares for WNV Season with Mosquito Traps

The City of Dallas is preparing once again for mosquito season.

The plan is very similar to last year’s plan, but there are some changes they hope will keep the number of cases of West Nile virus down.   Once again there will be 90 mosquito traps located throughout the city testing for West Nile virus.

They are hoping that this year’s cold winter will keep the number of West Nile deaths low and not spike like they did in 2012 when 21 people died. Read more

Mosquito Traps to fight Dengue Fever

As part of their efforts to control the spread of dengue in Singapore, the National Environment Agency (NEA) will be progressively placing traps in different residential areas to reduce the mosquito population.

The number of dengue cases had hit a historic high of 22,170 cases last year, with 3,420 cases detected so far this year.  Read more

New Findings May Help Control Disease-Carrying Mosquitoes

Mosquito sperm have a sense of smell — a surprising finding that could one day help control disease-carrying mosquitoes, researchers say.Mosquito Sperm

Mosquitoes use scent-detecting molecules known as odorant receptors in their antennae. These sensors help mosquitoes “sniff out” sources of blood as part of their sense of smell, technically known as olfaction.

Now, researchers have discovered mosquitoes have these same molecules in their sperm.  Scientists analyzed the mosquito species Anopheles gambiae, one of the most common carriers of malaria. They found odorant receptors on the whip like tails of the mosquitoes’ sperm. These molecules help to spur the beating of the tails, and thus help control the movement of the sperm, the researchers said.  read more

New Findings Could Lead to Better Mosquito Repellants and Traps

Every time a mosquito is lured to the scent of your skin, you’re at risk of contracting malaria, dengue fever, West Nile virus, or another deadly disease. A study published by Cell Press December 5th in the journal Cell has revealed an important class of neurons responsible for a mosquito’s attraction to human skin odor, as well as odors that stimulate and inhibit the activity of these neurons. The findings could lead to a new generation of repellants and traps for effective mosquito control worldwide.

“These findings open up very realistic possibilities of developing ways to use simple, natural, affordable, and pleasant odors to prevent mosquitoes from finding humans,” says senior study author Anandasankar Ray of the University of California Riverside.

“The powerful experimental approaches we have developed will help us find potential solutions that we could use not only here in the United States but also in Africa, Asia, and South America, where affordability is key in the war against these diseases.”   Read more

Mosquito Trapping To Continue in Phoenix

Mosquito activity is expected to decrease as temperatures fall. But the Maricopa County Environmental Services Department will continue to fog and set traps in Phoenix to prevent the spread of the mosquito-borne West Nile Virus.

And as the busy season for mosquitoes winds down, county spokesman Johnny Diloné said at least 500 mosquito traps will be set a week across the county.

Officials examine the traps for one of three conditions: if any of the trapped mosquitoes carry West Nile Virus, if it has more than 30 Culex mosquitoes (which are more likely to carry West Nile Virus), or if there are 300 or more mosquitoes in a trap.

Diloné said if the traps have one or more of these conditions, the county will fog the area. Exterminators fog between midnight and 5 a.m. — when most people are inside and won’t be fully exposed to the Permanone 30-30 and Zenivex E4 chemicals — around a square mile of where they collected the traps. One component of the traps is dry ice, which mimics human breathing and attracts mosquitoes. Read more

West Nile Virus Found in Rhode Island Mosquito Trap

A trap that was set on September 3 in Barrington, Rhode Island tested positive for West Nile virus. The positive result came from a pool of mosquitoes that were trapped near Barrington High School. The mosquitoes were of the Culex species, which feasts on both birds and mammals.

This is the fourth time this year that WNV has been found in Rhode Island. The Rhode Island Department of Health recently confirmed Eastern Equine Encephalitis in mosquitoes trapped near Tiverton and in Chapman Swamp. This brings the year’s total to four confirmed pools of WNV and three of EEE.  source
