Mosquito populations booming after rains: Three varieties to worry about, control and repel
That familiar buzz and bite are signs that mosquito season in Texas is here, according to a Texas A&M AgriLife entomologist. Sonja Swiger, Ph.D., Texas A&M AgriLife Extension Service entomologist and associate professor in the College of Agriculture and Life Sciences Department of Entomology, Stephenville, said biting mosquitoes are a seasons-long problem that often changes based on the environment. Which species are present and whether mosquitoes are an annoyance or vectors for diseases likely depends on those conditions, she said. Similarly, the temperature, availability of water and type of water available, such… Read More →
Where has West Nile virus gone?
If it seems you’re hearing less about West Nile virus (WNV) this summer, you are not imagining it. Although mosquitoes have been abundant this year, for some reason the virus has remained relatively quiet in 2019. Where has WNV gone? A paper written by epidemiologist Dr. Wendy Chung and colleagues in 2013 may offer some insights on the absence of the virus this summer. Those of us who lived in Dallas in 2012 may remember that summer as the worst human outbreak of WNV ever. Nearly 400 cases were… Read More →
And now it’s mosquitoes
Hurricane Harvey continues to leave its mark on Texas. Besides the giant cleanup, hoards of mosquitoes are now descending in many areas. The pictures are impressive. Just a couple of examples are enough to make the point. The young man in the picture here was fortunate to have chosen a sturdy shirt before venturing out last weekend. The mosquitoes in this picture are probably in the genus Psorophora, (sore ROFF oh ruh) one of our largest, most painful and aggressive biters. Psorophora mosquitoes have some impressive chops when it comes… Read More →
A chance to fight malaria
How would you like to save a life today? It’s not as hard as you might think. In the years since Bill Gates retired his position as CEO of MicroSoft Corporation, he and his wife Melinda have devoted tremendous effort to battling malaria. Malaria and the mosquitoes that transmit it is the single greatest killer of humans in the world, accounting for most of the 700,000+ mosquito-caused deaths annually. But unlike many of the other major problems in the world, solutions to the malaria epidemic are available now…. Read More →
New infographic on biting and stinging pests
Every now and then we get the opportunity to get a little creative with a partner who shares some of our mission. This month our partner is the Methodist Health System, and MHS Publication Specialist, Sarah Cohen. Sarah posed a challenge to a few of us subject matter experts, and her creative team, to come up with an infographic that would help inform you about the different kinds of pests in Texas that bite, sting and sometimes infect us. Here’s the final product and a link to the… Read More →
Quick fix for mosquitoes
This year my wife and I worked all spring to turn our backyard into a flowery paradise. We installed drip irrigation, planted new plants (including a bunch of perennials for attracting bees and butterflies) and mulched everything against the coming drought of summer. Now that summer’s here, however, the mosquitoes have decided that since everything’s so nice, they want to be in charge. In fact I believe every mosquito on the block knows about our backyard, making it difficult to go outside for even a few minutes without repellent. You… Read More →
First mosquito of the season
Before it’s old news, I wanted to make it official. It’s Aedes (AID ees) season again in north Texas. Last weekend I spotted my first Aedes albopictus (Asian tiger mosquitoes) of the season. So from now until November, get used to having these pesky mosquitoes around. Alex Wild, curator of the insect museum at the University of Texas in Austin (the OTHER Texas University) tweeted his first Aedes aegypti (yellow fever mosquito) of the season a month ago. Since then I’ve been tempting my local backyard mosquito population with my succulent, winter-white legs… Read More →
Zika Virus: What you need to know
Last December I wrote about bracing for a new mosquito-borne disease called Zika. Since then, evidence of a connection between Zika virus and two scary health conditions called Guillian-Barré syndrome and microcephaly has grown. Although there are still no known cases of Zika being acquired from mosquitoes locally, from within the U.S., there is a real possibility that Zika virus could reach Texas this summer. If so, these issues will become as important to the average stay-at-home Texan, as it is to those folks who are willing to… Read More →
Mosquito threat highest Now
In 2012 Dallas was the national epicenter of a West Nile epidemic. A mild winter and very hot summer combined to make conditions that resulted in approximately 400 reported cases and 19 deaths in Dallas county alone. While 2015 has not approached the mosquito numbers or disease transmission potential of 2012, this year’s data suggests that risk for getting a WNV infection from a mosquito is peaking higher than any time since then. Traditionally the potential for WNV transmission peaks in August and this year looks like no… Read More →
