Two novel mosquitocidal bacteria, VB17 and VB24, identified as new Bacillus species were isolated from dead mosquito larvae obtained in Florida aquatic habitats. Gas chromatographic analysis of fatty acid methyl esters (GC-FAME) and 16S rRNA sequencing indicated that VB24 is closely related to Bacillus sphaericus whereas VB17 does not have a close relationship with either Bacillus thuringiensis or B. sphaericus. Both isolates were significantly more active than B. sphaericus 2362 against Aedes taeniorhynchus, Anopheles quadrimaculatus, Culex quinquefasciatus larvae, and as active as B. sphaericus 2362 against Anopheles gambiae. Interestingly, however, both were not active against Aedes aegypti larvae, indicating some level of insecticidal specificity. © 2011 Elsevier Inc.

Mosquitoes often are collected as part of an arbovirus surveillance program. However, trapping and processing of mosquitoes for arbovirus detection is often costly and difficult in remote areas. Most traps, such as the gold standard Center for Disease control light trap, require batteries that must be charged and changed overnight. To overcome this issue we have developed several passive traps for collection of mosquitoes that have no power requirements. The passive traps capture mosquitoes as they follow a CO2 plume up a polyvinyl chloride pipe leading to a clear chamber consisting of a plastic crate. We believe the translucent, clear windows created by the crate inhibits escape. Once inside the crate mosquitoes readily feed on honey-treated Flinders Technology Associates cards that then can be processed by polymerase chain reaction for viral ribonucleic acid. Of the two designs tested, the box or crate-based passive trap (passive box trap, PBT) generally caught more mosquitoes than the cylinder trap. In Latin square field trials in Cairns and Florida, PBTs collected mosquitoes at rates of 50 to 200% of Center for Disease Control model 512 light traps. Mosquito collections by PBTs can be increased by splitting the CO2 gas line so it services two traps, or by placing an octenol lure to the outside of the box. Very large collections can lead to crowding at honey-treated cards, reducing feeding rates. Addition of fipronil to the honey killed mosquitoes and did not impact feeding rates nor the ability to detect Kunjin viral ribonucleic acid by polymerase chain reaction; this could be used to minimize crowding affects on feeding caused by large collections. The passive traps we developed are made from inexpensive, commonly available materials. Passive traps may thus be suitable for collection of mosquitoes and potentially other hematophagous dipterans for pathogen surveillance. © 2013 Entomological Society of America.

A group of researchers, mosquito and coastal managers, and consultants joined together to explore issues of concern to coastal and mosquito management in mangrove forests. At a 1-day workshop in Florida, participants identified issues that are important for their roles. The issues were subsequently compiled into a matrix and the participants were asked to individually assess the importance and urgency of each. The most important issues for everyone included habitat responses to management, community attitude, public education, interaction between agencies, local connectivity, sea-level rise (SLR) loss of wetlands, and conservation. Most urgent were public education, conservation easements, local connectivity, SLR, loss of wetland, restoration, and conservation. There were differing viewpoints among the roles that appeared to be related to responsibility for and ability to influence on-ground outcomes. This is reflected in mosquito and coastal managers who viewed issues broadly and ascribed higher levels of importance and urgency to them than did researchers and consultants. We concluded that collaboration is a key issue. Barriers to collaboration include knowledge differences between agencies. Facilitators of collaboration include interaction, trust, and shared goals. © 2014 by The American Mosquito Control Association, Inc.

Specimens of a mosquito new to the continental USA, Aedes pertinax, were retrospectively identified from 2 collections made in 2011 in Indian River County, FL. Routine mosquito surveillance in subsequent years yielded more than 700 specimens appearing in 100 collections. The distribution of this mosquito in Florida and the United States is currently unknown, and recognition of the adult female is likely hampered by morphological similarities to Ae. atlanticus and Ae. tormentor. © 2015 by The American Mosquito Control Association, Inc.

High mosquito populations have always been a part of Florida's environment. While mosquito-transmitted diseases have played a major role in Florida's history, saltmarsh mosquitoes have not been implicated in these disease outbreaks. However, the impact of high saltmarsh mosquito numbers on the well-being of residents and visitors cannot be underestimated. Coastal wetland management efforts in Florida, which date back to the 1920s, have included ditching, dredging and filling, and impounding, all having mosquito control and environmental benefits and liabilities. In the early 1980s, efforts to encourage coastal wetlands management for both mosquito control and environmental interests came to the forefront. This resulted in the Florida Legislature creating the Florida Coordinating Council on Mosquito Control and its Subcommittee on Managed Marshes. Through the efforts of these committees, a heavy investment in research, interagency cooperation, and public acquisition of coastal wetlands property, tremendous progress has been made in management of coastal wetlands. This has occurred largely by implementing management and restoration techniques that minimize environmental impacts, allow for mosquito control, and minimize the need for pesticide use. Continued efforts are needed to place into public ownership remaining privately owned coastal wetland property to allow implementation of best management practices on these important habitats. © 2011 Springer Science+Business Media B.V.
