Kevin A. Caillouet, a research entomologist with the St. Tammany Parish Mosquito Abatement District, will talk about the West Nile virus at 7 p.m. Tuesday at the East Bank Regional Library, 4747 W. Napoleon Ave., Metairie.

Caillouet’s presentation is presented by NOLA Science Café. Science cafés are events that take place in casual settings and feature an engaging conversation with a scientist about a particular topic. They welcome people who may or may not typically get involved in scientific discussions. They are not club meetings for scientists and science majors, nor do they take place exclusively in lecture halls or science museums. Science cafés happen in informal community gathering spaces all over the world.

According to Caillouet, every spring, thousands of birds hatch into a harsh reality of predators, parasites and pathogens. This seasonal pulse of susceptible West Nile virus avian hosts and abundant mosquito vectors fuel the potential for West Nile outbreaks in humans. Techniques combining thermal imaging, fieldwork and mathematical models are leading to new insights into the ecology of the virus.
