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. Avoiding Mosquito Bites – Tips From Grayson County Health Dept.
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
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
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
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
Mosquito sperm have a sense of smell — a surprising finding that could one day help control disease-carrying mosquitoes, researchers say.
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
