Field Evaluation of Two Topically Applied Insect Repellent Products Containing IR3535 Against Mosquitos in Louisiana

Status unconfirmed · Not applicable

Conditions studied: Bites and Stings

In brief

To determine the efficacy and duration of protection of two topically applied insect repellent products at preventing landing by mosquitos. The study will follow the EPA Product Performance Test Guidelines1. It is intended to test the products against natural populations of mosquito species of public health importance within the genera Aedes, Anopheles, and Culex, and to replace data from one site previously tested in Florida with data from a site in Louisiana with adequate landing pressure from target mosquito species of public health relevance.
