A Multiplex PCR-Based Molecular Identification of Five Morphologically Related, Medically Important Subgenus <i>Stegomyia</i> Mosquitoes from the Genus <i>Aedes</i> (Diptera: Culicidae) Found in the Ryukyu Archipelago, Japan

Abstract

Internal transcribed spacer regions of ribosomal DNA were sequenced, and new species-specific primers were designed to simplify the molecular identification of five morphologically related subgenus Stegomyia mosquito species--Aedes aegypti, Ae. albopictus, Ae. riversi, Ae. flavopictus, and Ae. daitensis--found in the Ryukyu Archipelago, Japan. Each newly designed primer was able to amplify a species-specific fragment with a different size. Conditions for multiplex PCR were optimized to identify all five species in a single PCR. This method is a convenient tool for entomological field surveys, particularly in arbovirus endemic/epidemic areas where some of these species coexist.
