Research Project: Factors Affecting Hematophagous Arthropod Attraction to Infected and Uninfected Animals

Location: Arthropod-Borne Animal Diseases Research

Project Number: 3020-32000-006-02
Project Type: Specific Cooperative Agreement

Start Date: Sep 01, 2011
End Date: Aug 31, 2015

Objective:
Arthropod vectored disease transmission is dependent on insects becoming infected by feeding on diseased hosts. The objective of this project is to test if mosquitoes and flies are more attracted to diseased animals than infected ones. If there is a quantifiable preference for diseased animals, the increased feeding may be associated with behavioral or physiological changes in the host.

Approach:
The feeding preferences of the mosquitoes and flies will be quantified to determine if infected animals are preferentially fed upon. If this is found, then the odor volatiles from infected animals will be collected and compared to healthy animals. Differences in odor volatile profiles will be tested with electro-antennal detection (EAD) to determine the mosquito or flies attraction to the specific components of the odor profile.
