State ‐wide survey of Aedes aegypti and Aedes albopictus (Diptera: Culicidae) in Florida
ABSTRACTAedes aegyptiandAedes albopictusare invasive mosquito species with geographic ranges that have oscillated within Florida since their presence was first documented. Local transmission of dengue, chikungunya, and Zika viruses serves as evidence of the public health importance of these two species. It is important to have detailed knowledge of their distribution to aid in mosquito control efforts and understand the risk of arbovirus transmission to humans. Through a partnership involving the University of Florida Institute of Food and Agricultural Sciences Cooperative Extension Service and the Florida Medical Entomolo...

Characterization of α-Glucosidases From Lutzomyia longipalpis Reveals Independent Hydrolysis Systems for Plant or Blood Sugars
In this report, the authors consider that transglycosylation might be an adaptation for the obtention of monosaccharides from sucrose without the increase in osmolarity, as a simple hydrolytic reaction of a 0.7 M sucrose solution (phloem concentration) might result in osmotic shock for the midgut epithelial cells. In this respect, L. longipalpis enzymes might have the same biochemical adaptation. It would be very interesting to observe if this is a common trait of α-glucosidase from insects feeding on nectar or phloem sap, and verify if this is a case of evolutionary divergence or convergence. Two main mechanisms o...

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...

Mosquito Species Capable of Transmitting Zika Virus Found in Dane County
Researchers at the University of Wisconsin Medical Entomology Laboratory (UWMEL) and health officials from the Department of Health Services (DHS) and Public Health Madison-Dane County (PHMDC) today announced that the Aedes albopictus mosquito has been found in Dane County. This is the first documentation of this species of mosquito in Wisconsin. Aedes albopictus is one type of mosquito that is capable of spreadingZika virus, however there is no evidence of Zika-...(see release)

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....
