Mosquito feeding habits. For each Culex species captured at the wetlands sites, the relationship between feeding success (proportion engorged of total captured) to overall biting intensity (total number of all Culex captured, transformed to log 10 N) on the same collection night was examined using linear regression, limited to collection periods when ≥10 mosquitoes of the species being analyzed were captured. It is important to note that not all mosqui-toes carry WNV, not all mosquitoes feed Who, when and where mosquitoes bite and how they find their targets.

Measuring biting itself is fraught with ethical concerns, so the landing rate of mosquitoes on humans is often used as a proxy measure. The most common mosquito species feed at dawn and dusk, and for a few hours into dark. The percentage repellency increased when the concentration of essential oils increased.
