This Year Might Be the Worst Tick Season Ever. Here ’ s Why
Marci Silbert wasn’t walking far on the evening of May 6. She, her husband, and another couple were visiting friends for dinner, and after eating, took a brief stroll down a short path to a small pond on their hosts’ property in the Berkshires in Massachusetts. They lingered for just a few moments, and then walked back. But that was all it took.
The next day, her husband noticed a tick embedded in his forearm. Silbert had one on the inside of her knee, and the husband in the other couple had one on his thigh. Out of an abundance of caution, they went to the hospital, had them removed, and were given prophylacti...

The Least Toxic Ways to Protect Yourself from Ticks
When it comes to keeping away creatures that creep and crawl, the U.S. doesn’t mess around. More than 198 million Americans used insect repellent last year, a figure that is expected to top 200 million this year. Much of that is to ward off ticks, which are technically arachnids and carry more than a dozen diseases.
But the repellents themselves can present concerns of their own with their pungent smells, occasional irritation, and labels full of mystifying chemicals most people have never heard of.

Insect Experts Say People Should Calm Down About the Threat of ‘Murder Hornets’
Insect experts say people should calm down about the big bug with the nickname “murder hornet” — unless you are a beekeeper or a honeybee.
The Asian giant hornets found in Washington state that grabbed headlines this week aren’t big killers of humans, although it does happen on rare occasions. But the world’s largest hornets do decapitate entire hives of honeybees, and that crucial food pollinator is already in big trouble.
Numerous bug experts told The Associated Press that what they call hornet “hype” reminds them of the 1970s public scare when Africanized honeybees, nicknamed &l...

Hot, Dry New England Summer Brings Fewer Cases Of Lyme Disease
SCARBOROUGH, Maine (AP) — New England’s hot summer might be helping keep the ticks that carry Lyme disease at bay.
The Northeastern states — which are some of the worst for Lyme in the U.S., posing a hazard to residents and vacationers alike — are still totaling the number of Lyme cases from the summer months, and there will likely be more in the fall. But preliminary indicators show the disease abating, and public health authorities are finding fewer deer ticks, state officials and researchers said.
In Maine, there had been a steady annual growth of Lyme cases, including a jump of 23 percent to more than 1...

Fewer Scientists Are Studying Insects. Here ’s Why That’s So Dangerous
In the summer of 2016, Jerome Goddard, a medical entomologist in Mississippi, received an email from the U.S. Centers for Disease Control and Prevention (CDC) with a desperate ask. The agency was conducting an “urgent” search for insect scientists around the U.S. who could take up to a six-month paid leave from work to help the CDC fight the Zika outbreak in the U.S., and possibly respond to areas with local transmission if needed.
“That’s how bad it is—they need to borrow someone,” says Goddard, an extension professor of medical entomology at Mississippi State University. “We can&...

CDC surveys find increase in the number of U.S. counties with Aedes aegypti and Aedes albopictus mosquitoes that can spread Zika
The Southern United States shows a substantial increase in the number of counties that reported evidence of the mosquitoes that can spread chikungunya, dengue, and Zika viruses, according to new research by the Centers for Disease Control and Prevention (CDC) published in the Journal of Medical Entomology.

Mosquitoes (Diptera: Culicidae) From the Northwestern Brazilian Amazon: Padauari River
The mosquito fauna (Culicidae) from remote northern areas of the State of Amazonas were sampled using Centers for Disease Control and Prevention, Shannon, Malaise, and Suspended traps, together with net sweeping and immature collections. One hundred and seven collections were performed in five localities along the Padauari River, State of Amazonas, Brazil, during June 2010. The 20,557 mosquitoes collected are distributed in 17 genera, representing 117 different species, of which four are new distributional records for the State of Amazonas. Furthermore, there are 10 morphospecies that may represent undescribed new taxa, ei...

Florida Sees Second Local Dengue Case This Year
By Laura Geggel
A person in Florida has caught a locally transmitted case of dengue fever, news sources reported Wednesday. The case is the first in which a person caught dengue from a mosquito bite within Miami-Dade County in 2016.
The person diagnosed with the viral infection has received treatment and is expected to fully recover, CBS Miami reported. The case is also Florida’s second local dengue case of 2016, according to CBS Miami. In 2015, the state reported one locally transmitted case of dengue, and in 2014 it had six known locally acquired cases of the disease, according to the Florida Department of Health....

Reported Distribution of Aedes (Stegomyia) aegypti and Aedes (Stegomyia) albopictus in the United States, 1995-2016 (Diptera: Culicidae)
Aedes (Stegomyia) aegypti (L.) and Aedes (Stegomyia) albopictus (Skuse) transmit arboviruses that are increasing threats to human health in the Americas, particularly dengue, chikungunya, and Zika viruses. Epidemics of the associated arboviral diseases have been limited to South and Central America, Mexico, and the Caribbean in the Western Hemisphere, with only minor localized outbreaks in the United States. Nevertheless, accurate and up-to-date information for the geographical ranges of Ae. aegypti and Ae. albopictus in the United States is urgently needed to guide surveillance and enhance control capacity for these mosqu...

TrapTech R-Octenol Lure Does Not Improve the Capture Rates of Aedes albopictus (Diptera: Culicidae) and Other Container-Inhabiting Species in Biogents Sentinel Traps
This study evaluated the effectiveness of the TrapTech lure (TT lure), containing R-octenol, alone or in combination with the human skin lure in a BGS trap to capture Ae. albopictus and other species. BGS traps with human skin lures or a combination of the two lures collected approximately twice as many Ae. albopictus females compared to those with TT lures. Unlike previous studies, baiting BGS traps with TT lures did not result in increased diversity of mosquito species, or in higher numbers of other container-inhabiting Aedes species. Although human skin lures were clearly superior to TT R-octenol lures in BGS traps, R-o...

Determination of Insecticidal Effect (LC50 and LC90) of Organic Fatty Acids Mixture (C8910+Silicone) Against Aedes aegypti and Aedes albopictus (Diptera: Culicidae)
Emerging and re-emerging vector-borne diseases such as chikungunya and dengue and associated Aedes vectors are expanding their historical ranges; thus, there is a need for the development of novel insecticides for use in vector control programs. The mosquito toxicity of a novel insecticide and repellent consisting of medium-chain carbon fatty acids (C8910) was examined. Determination of LC50 and LC90 was made against colony-reared Aedes aegypti (L.) and Aedes albopictus (Skuse) using probit analysis on mortality data generated by Centers for Disease Control and Prevention bottle bioassays. Six different concentrations of C...

Feeding Patterns of Mosquitoes (Diptera: Culicidae) in the Atlantic Forest, Rio de Janeiro, Brazil
The stomach contents of culicids from the Atlantic Forest in Rio de Janeiro state, Brazil, were analyzed using the precipitin technique to evaluate the feeding patterns of the species. Sampling was performed from February 2012 to December 2013, using CO2-baited Centers for Disease Control and Prevention traps to catch mosquitoes from 15 00 to 07 00 hours. The following antisera were used: bird, rodent, opossum, human, horse, capybara, lizard, and frog. Of the 325 adult bloodfed females caught and analyzed, 273 (84.0%) reacted in the precipitin test. The percentage of specimens with a positive reaction to a single antiserum...
