The vision of Culex quinquefasciatus was studied in the laboratory. The attractiveness of colors (black, white, brown, yellow, blue, a skin tone) was evaluated with respect to the collection of Cx. quinquefasciatus in natural light, in the dark, and in ultraviolet light. Culex quinquefasciatus prefers both black and brown in natural light and ultraviolet light, but, as expected, there is no pre...

This paper studies the relationship between ambient light and criminal activity. I develop a Becker-style crime model that shows sudden increase in produces larger reduction areas with less public lighting. Daylight savings time (DST), natural experiment used, induces sharp during crime-intense hours. Using geolocated data on lighting for city of Montevideo Uruguay, regression discontinuity est...
