Abstract

The attraction of Aedes albopictus (Skuse) to hands and forearms of human subjects treated with several concentrations of L-LA solution were studied in a test chamber containing proboscis-amputated mosquitoes. Fewer mosquitoes alighted on L-LA treated human skin than on water-treated control skin. Similar results were found using normal mosquitoes following L-LA and water treatment of mouse skin. The relative repellent effects of L-LA varied with concentration. The minimum repellent concentration was lower than previously reported for human skin. The number of alightments decreased at increasing concentrations of L-LA, demonstrating the absolute repellency of L-LA. Unlike previous reports suggesting that L-LA attracted mosquitoes, our studies using human and mouse skin showed that L-LA exhibited both relative and absolute repellency.
