Controlling the invasion and spread of Aedes albopictus in the Los Angeles Basin

PRINCIPAL INVESTIGATOR: Christopher M. Barker

PROGRESS REPORT FOR YEAR 1 (2012) BACKGROUND AND SIGNIFICANCE (see more detailed background in year 2 proposal) Aedes albopictus is a vector of global health concern because it bites humans and is a competent vector of many arboviruses, including dengue, West Nile virus, and chikungunya1. This species invaded California repeatedly during the last four decades2, 3, 4, 5, including a recent infestation detected during late 2011 in the El Monte and South El Monte area of Los Angeles County, and it has already established populations in similar climates in southern Europe 6, 7, 8, 9, 10. This project focuses on development of spatial models that simulate adult mosquito reproduction and movement between locations, aspects that are particularly important for targeting control of Ae. albopictus or other invasive species because of the potential for spread beyond the containment area or repopulation from neighboring areas following successful local control 11. In this progress report, we focus on our work during 2012. More detailed background and justification for the work are presented in our proposal for year 2.
