Research Project: Area-Wide Management of the Asian Tiger Mosquito: Enhanced Tools and Message Dissemination

Location: Mosquito and Fly Research

Project Number: 6036-32000-050-02-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jun 18, 2014
End Date: Sep 30, 2014

1. Characterize the source and genetic makeup of populations of Ae. albopictus across the U.S. 2. Understand the mechanisms underlying the response of populations to varying temperature regimes in order to develop a more precise and accurate degree-day model to guide control programs. 3. Support the dissemination of information from the AW-ATM project through additional peer-reviewed publications and enhancement of the webpage. These are all ongoing projects with key personnel in place and therefore achievable during FY14.

(1) Rutgers University will implement a recently developed strategy to genotype populations of Ae. albopictus at thousands of single and low copy DNA loci (SLC Seq, Fonseca and Condon in prep) to examine the degree to which local evolution vs. multiple introductions from across the temperate and tropical range, are contributing to the patchiness in control efficacy. (2) Collaborator at Georgetown University, will replicate earlier experiments that uncovered metabolic differences between temperate and tropical populations of Ae. albopictus identifiable by distinct cytochrome oxidase mitotypes (Armbruster et al in prep) and develop a rapid mitotype ID assay developed to predict the response of populations to temperature and latitude. (3) Collaborator at Louisiana State University (LSU), a former Research Associate in the AW-ATM and now an assistant professor and extension specialist at LSU, will develop experiments to examine the effects of temperature on feeding rates and growth rate of Ae. albopictus. All results will be immediately incorporated into the existing degree-day model that is already available for download on the AW-ATM webpage. Of note, mosquito control programs in the northeast (NJ, NY, and PA) are already actively using the degree-day model to assess interventions. (4) Publish findings of the AW-ATM in peer-reviewed journals. (5) Contract with Web designer to enhance functions on the AW-ATM webpage, such as faster and more robust access, protection from hackers, ability to use the costing tool and degree-day model directly on the web, and supporting Twitter and Facebook access.
