A Concise Guide on the Bionomics and Key Morphological Characteristics for Identifying Aedes pertinax (Grabham, 1906) – a Mosquito Species from the Neotropics Expanding in Geographic Range

Ana L. Romero-Weaver, Michael T. Riles, Kristin Sloyer, Yoosook Lee, Lindsay P. Campbell, and Bryan V. Giordano

Aedes pertinax is a non-invasive mosquito first described in Jamaica by Grabham in 1906. It is currently classified in the Protoculex Group. It was first identified in the U.S. in 2015; its current distribution is unknown because it is so difficult to differentiate it from other mosquito species that are morphologically similar. It has not been reported in association with humans or animal diseases, but Ae. Atlanticus, another mosquito in the Protoculex Group, is a vector of the Keystone virus and the West Nile virus, which have the potential to cause encephalitis and death. Moreover, Ae. serratus, once classified as synonym of Ae. pertinax, was reported infected with yellow fever in Brazil in 2008. Because Ae. pertinax may be a vector and because it has expanded its geographical range, it should be monitored closely. This publication provides a description of the species so that it can be identified and monitored.

An Overview of Integrated Mosquito Management Performed by Mosquito Control Programs in Florida

Miranda J. Tressler and Eva A. Buckner

Mosquito control programs in Florida manage mosquito populations and reduce the public risk of contracting mosquito-borne diseases. They use many methods to target multiple life stages of mosquitoes in a process called integrated mosquito management, or IMM. The American Mosquito Control Association considers IMM the best way to manage mosquitoes and reduce mosquito-borne disease transmission. An IMM program includes community engagement, mosquito surveillance, source reduction, biological control and the application of targeted insecticides, and monitoring for insecticide resistance. Public perception of mosquito control programs is sometimes negative, especially when people do not have a good understanding of the behind-the-scenes steps of IMM. This publication is intended to educate Florida residents about mosquito control programs by providing an overview of the regulation of these programs and a full understanding of the IMM strategies they practice.

Chagas Disease: A Review of Vector-Borne Transmission by Triatomine Bugs (Hemiptera, Reduviidae, Triatominae)

Bethany R. Eutsey, Cameron J. Jack, Shelley A. Whitehead, and Eva A. Buckner

Chagas disease is a potentially fatal, chronic disease caused by Trypanosoma cruzi, a protozoan parasite. It causes 6 to 8 million cases and 50,000 deaths each year. Humans and animals usually become infected with T. cruzi via triatomine bugs, also called kissing or conenose bugs, found only in the Americas. Disease transmitted by triatomine bugs generally occurs in rural areas of Mexico, Central America, and South America, but it is becoming more prevalent in non-endemic areas like the US as asymptomatic infected people move from rural to urban areas of Latin America and other regions.  In the US, approximately 300,000 people are currently infected with Chagas disease, 18,000 in Florida. Most if not all of them were infected elsewhere; local transmission of Chagas disease via triatomines in the US is rare. Awareness and understanding of Chagas disease are critical to detect and treat cases early. This publication is intended for anyone interested in learning more about Chagas disease.

Dengue and Dengue Virus in Florida

Yasmin V. Ortiz, Daniel W. Pérez-Ramos, Eric P. Caragata, and Panpim Thongsripong

This publication provides an overview of dengue fever, focusing on its epidemiological landscape in Florida. Dengue, caused by dengue virus and transmitted through the bites of infected Aedes mosquitoes, is a major global health concern. Florida has experienced local dengue transmissions, and the incidence of dengue is increasing in the state. The biology and ecology of the primary vectors, Aedes aegypti and Aedes albopictus, play  important roles in the disease's transmission cycle. No vaccine and no specific antiviral treatments are yet available, and diagnosis is difficult because dengue symptoms overlap with those of other, similar febrile illnesses. Prevention and control strategies, such as mosquito management, are therefore crucial to mitigate disease risks. Alongside urbanization, climate change, and globalization, incidence of dengue is increasing in Florida. Continued vigilance and research will help to combat this public health threat.

El Zika, un Virus Transmitido por Mosquitos

L. P. Lounibos, B. W. Alto, N. D. Burkett-Cadena, C. C. Lord, C. T. Smartt, and C. R. Connelly

Zika es un virus transmitido por mosquitos que se ha esparcido recientemente en regiones tropicales y ha causado epidemias, especialmente durante los últimos 8 o 9 años. En su ámbito nativo en África Occidental y Uganda, el virus se mantiene en los bosques, circulando entre mosquitos que viven en huecos de árboles y primates arbóreos; las infecciones de humanos se consideran incidentales y de poca importancia médica. Una cepa del virus que se implicó en brotes en Polinesia Francesa emergió en el Norte de Brasil en el 2015 y causó gran consternación debido a la alta incidencia de microcefalia en bebes nacidos de madres que fueron infectadas con el virus durante la gestación. Transmisión local, principalmente por el mosquito de la fiebre amarilla Aedes aegypti, ha sido documentada en la mayoría de los países tropicales de las Américas, pero aún no se ha detectado en Los Estados Unidos Continentales. Los síntomas de la infección incluyen, salpullido, dolor de cabeza, fiebre, dolor muscula

Fact Sheet: West Nile virus

Yasmin Tavares, Amely Bauer, Lawrence Reeves, and Lindsay Campbell

Introduced to the United States in 1999, West Nile virus (WNV) is transmitted from mosquitoes to humans and equines. With over 52,000 reported human infections, it is the most frequent cause of mosquito-borne disease in the continental United States. Many mosquito species can transmit WNV, and many wildlife species can be infected with the virus and transmit it to biting mosquitoes, which makes identifying WNV's high risk areas or time periods complex. The US equine industry, domestic pets, and livestock are all at risk from harm from WNV. Many equine WNV epizootics have occurred since 1999, with more than 30,000 equine cases reported in the United States. Since WNV's introduction to Florida in 2001, infections have been reported in a total of 460 people and 757 equines. This publication provides information about WNV to the general public, researchers and stakeholders in mosquito control, and public health professionals.

Human Malaria

C. R. Connelly, J. K. Nayar, C.D. Morris, and R. H. Baker

Malaria in humans is a disease transmitted by mosquitoes in the genus Anopheles and caused by any one of four species of microscopic protozoan parasites in the genus Plasmodium (P. vivax, P. falciparum, P. malariae and P. ovale ) distributed throughout the world. Malaria was one of the major endemic diseases in the United States for more than four centuries (Russell, 1968). As recently as 1935, malaria caused 4,000 deaths every year in the United States. However, by the 1940s, the annual death toll had been reduced to 400, and by 1952 it was down to 25 with little or no local transmission. In the United States and elsewhere, malaria was eradicated by draining larval habitats, treating patients with antimalarial drugs, applying mosquito larvicides and adulticides, and screening doors and windows.

One Health Defined: A New Way to Think about Wellbeing

Amely Bauer and Lindsay Campbell

“One Health” is a way of conceptualizing wellbeing that recognizes the interconnection and co-dependence of human, animal, plant, and environmental health and focuses on collaborating across scientific fields to improve health across all components of the ecosystem. One Health was formalized in the early 2000s after the first cases of severe acute respiratory disease (SARS) and the rapid spread of highly pathogenic avian influenza (H5N1) drew international attention and concern about how pathogens can move and spread across the human, animal, and environmental interface. SARS and H5N1 highlighted the need for collaborative efforts to address diseases in an increasingly connected world. One Health is now used broadly to address health challenges across human, animal, and plant systems. This publication provides information about One Health to the public and to researchers and stakeholders in mosquito control and public health professions.

Using Wolbachia Bacteria to Control Mosquitoes and Mosquito-Borne Disease

Leena A. Salama, Abdullah A. Alomar, Daniel W. Pérez-Ramos, and Eric P. Caragata

This publication is intended for both the general public and mosquito control professionals. It outlines the use of the bacterium Wolbachia pipientis as a tool to control mosquito populations and reduce the spread of mosquito-borne disease. Biting mosquitoes transmit many pathogens that cause deadly diseases in people, our pets, and our livestock. Collectively, malaria, dengue, West Nile, filariasis, and other mosquito-borne diseases result in millions of infections and hundreds of thousands of deaths every year. Effective vaccines for most of these have not been developed or are not yet available to the general public, and disease management is focused on controlling mosquito populations. Insecticides have become less effective over the past fifty years as mosquito populations all over the world have developed resistance. This has driven scientists to explore new options for controlling mosquitoes, including using the bacterium Wolbachia pipientis.
