Florida Container Mosquitoes

Container mosquitoes inhabit small natural and artificial water-filled vessels during their immature stages. This publication lists and illustrates fifteen species of them, including two exotics that are the most important vector species of dengue, chikungunya, yellow fever, and Zika viruses. It also describes available control measures, the best for homeowners being to eliminate aquatic habitat by draining standing water in containers near homes.

Container Mosquito Habitat Community Cleanup: A How-To Guide for Event Organization

Being bitten by the container mosquitoes Aedes aegypti and Ae. albopictus means a higher risk of becoming infected with Zika, dengue, or chikungunya virus. Container mosquitoes develop in the water that collects in discarded tires, jars, cans, buckets, and boats. The best way to prevent irritating bites and dangerous mosquito-transmitted illnesses is to get rid of all trash that holds water. This 6-page fact sheet written by Amy Hallock, Eva A. Buckner, Ricky W. Telg, and Alena R. Poulin and published by the UF/IFAS Entomology and Nematology Department is packed with recommendations that will help you to successfully develop and host a cleanup event to reduce potential mosquito larval habitats in your community and keep yourself and your neighbors safe.

Collection and Rearing of Container Mosquitoes and a 24-h Addition to the CDC Bottle Bioassay

Container mosquitoes (Diptera: Culicidae) oviposit their eggs in both natural and artificial containers. Many container mosquito species also serve as important vectors of disease-causing pathogens including Aedes aegypti, Ae. albopictus, and Ae. triseriatus. Control of these species can be done through the use of adulticide sprays. The efficacy of these treatments is highly dependent on the insecticide susceptibility status of the local mosquito populations. This paper provides protocols on collecting and rearing container mosquitoes for use in the Centers for Disease Control and Prevention (CDC) bottle bioassay. A brief description of the CDC bottle bioassay is provided as well as a standardized protocol for the incorporation of a 24-h mortality to the CDC bottle bioassay. Results from this 24-h holding addition to the CDC bottle bioassay reveal that some forms of resistance may be missed without the incorporation of the additional mortality reading. These protocols provide a foundation for new laboratories to establish rearing protocols and begin conducting resistance monitoring.

A Mosquito Workshop and Community Intervention: A Pilot Education Campaign to Identify Risk Factors Associated with Container Mosquitoes in San Pedro Sula, Honduras

Dengue poses a significant public health threat and results in ~96 million clinical cases every year. Central America is a region burdened by neglected tropical diseases, including dengue. The primary vectors of dengue, Aedes aegypti and Aedes albopictus, are widely distributed in Honduras. Additionally, sustained and consistent mosquito control is lacking in the country. Successful control of container mosquitoes relies heavily on participation from community leaders, stakeholders, and the community itself. We conducted a pilot study in San Pedro Sula, Honduras where community leaders and stakeholders were trained on mosquito biology and control and were able to apply that knowledge to an underserved community in San Pedro Sula. Surveys to assess the number and type of containers in the community and the number of containers on the residence identified associations with select socioeconomic factors and other variables based on survey questions. The average number of containers on the premises was 15 (± 2.3) and the most prevalent containers (>50%) were flowerpots, garbage, and toys, which could be targeted in mosquito control programs. This pilot study offers a framework for training community leaders and stakeholders to create a sustainable community-based vector control program for container mosquitoes.
