Giant hornets genuinely frightening
The Asian giant hornet has recently been spotted close to the Canadian border in Washington state. Photo courtesy Washington State Department of Agriculture. Last year’s quiet arrival of a foreign wasp known as the Asian giant hornet is no longer a secret outside of Washington state. Within the past few days, all the major TV networks have broadcast stories of the arrival of the wasp to the Pacific Northwest. Known to entomologists as Vespa mandarinia, it has been named by the press the ‘murder hornet’. It’s hard… Read More →
Kudzu bug in Texas
Last week Texas became the fourteenth state with verified populations of kudzu bug. An alert county Extension agent, Kim Benton, reported kudzu bugs from a home garden in Rusk, TX, south of Tyler. The bugs were clustered on eggplant and other vegetables before being transplanted into the garden. The kudzu bug saga in the U.S. began in October 2009 when millions of small, pill-like bugs startled homeowners across nine counties in northeast Georgia. The never-before-seen insects covered the sides of homes by the thousands, and concerned citizens began… Read More →
Disinfectants are pesticides–so use safely!
What do “pest control” and public health campaigns against SARS Cov-2 have in common? Both activities use pesticides. In the eyes of the law, sanitizer and disinfectant products are considered pesticides. And if you’re a little wary of using pesticides, you should exercise the same caution when choosing and using a disinfectant. Let’s start with some basics. The term ‘pesticide’ refers to any substance or mixture of substances used to prevent, destroy, repel or mitigate a pest. All pesticides are regulated by the U.S. Environmental Protection Agency (EPA),… 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 →
Texas/Oklahoma Pollinator Project
This summer Texas A&M AgriLife is conducting a citizen science project to document the preferred host plants of Texas & Oklahoma pollinators. In the process some energetic volunteers and I will be learning a lot more about how to plant a successful pollinator garden. Last week I presented information about pollinators and how the project works to volunteers in the Dallas area. If you are signed up as a volunteer, but missed the training, an edited version of the training is available here https://youtu.be/JfSpwlYcM3s This training should prepare… Read More →
Sunshine and wildflowers–its mosquito time again
Two weekends ago my wife and I went for a long bike ride. It was one of those rare, completely beautiful spring days, cool air and wildflowers lining the roads. I knew it was going to be a long ride, and I knew the Texas sun was shining; but somehow the need for sunscreen never entered my mind (my wife had the good sense to lather up). It was a wonderful ride; but I’m still paying the price today, with the skin on my arms peeling like an… Read More →
Dr. Don R. Read
The next best thing to being great, it’s been said, is walking next to someone great. I am grateful to have had the chance to meet and get to know the late Dr. Don R. Read, who passed away on March 21, 2019. He was one of our local colorectal surgeons in Dallas, and a great man in many ways. Dr. Read made his (unfortunate) acquaintance with entomology in 2005 when he was bitten by a mosquito infected with the west Nile virus. He told his story of… Read More →
Bug bombs bomb
For many years the go-to solution for DIY pest control was the bug bomb. Got fleas? Get yourself a bug bomb. Cockroaches in the kitchen? Bug bomb! Most recently, it’s bed bugs. See a bed bug? Reach for the bug bomb. But do bug bombs (also known as total release aerosols) really work? Not very well according to a recent paper was published last month in the Open Access journal BMC Public Health. Researchers at North Carolina State University found that not only did bug bombs under-perform (not even… Read More →
Good news about monarchs, but…
News headlines often bear a second look. And this week’s “good news” about monarch butterflies is no exception. News sources this week are reporting that monarch butterfly colonies covered almost 15 acres of Mexican mountainside in 2019, a 144% increase from last winter. Colony sizes are based on estimates of the total acreage of trees covered with monarchs in the Monarch Butterfly Biosphere Reserve in Mexico–the main overwintering site for eastern monarch butterflies. Acreage estimates provide an index as to how many butterflies survived the previous year’s… Read More →
Giving Monarchs a hand
Where have all the butterflies gone? If you think there are fewer butterflies, and just plain bugs, on your windshield compared to a few years back, you’re probably right. Recent studies point to alarming declines in both insect and butterfly populations. Most scientists think that the primary causes for these declines are the many changes we humans are making to our environment. As we replace plant-diverse rural landscapes with simplified urban and suburban streets and lawns, we reduce habitat abundance and food supply for butterflies, among other insects. … Read More →
