First Record of<i>Wyeomyia</i>(<i>Wyeomyia</i>)<i>mitchellii</i>(Diptera: Culicidae) in French Polynesia

Abstract

Wyeomyia (Wyeomyia) mitchellii (Theobald) was discovered in 2007 and 2008, respectively, in Moorea and Tahiti, two islands of the Society Islands (archipel de la Société) in French Polynesia. A few adult specimens were captured using a CDC backpack aspirator and BG-Sentinel mosquito traps. Wy. mitchellii larvae were found in water-impounding bromeliads and aroids at various survey sites around Tahiti. Imported bromeliads likely played a critical role in the introduction, establishment, and maintenance of Wy. mitchellii in Tahiti and Moorea. Bromeliads and aroids are common in residential areas, thereby increasing the exposure of human and domestic animals to Wy. mitchellii, which is of public health and veterinary concern. The establishment of Wy. mitchellii in French Polynesia requires further study.
