ABSTRACT This study examined the effectiveness of sodium chloride (NaCl) as an oviposition repellent for Aedes albopictus females. Oviposition responses to 0.5%, 0.75%, 1.00%, 1.25%, and 1.5% solutions of pure NaCl were evaluated over 8 days using ovitraps. Gravid Ae. albopictus females showed a reduction in oviposition at all NaCl concentrations. Compared with controls, the inhibition of oviposition ranged from 84.4% to 97.0% at concentrations above 0.5% NaCl. We also show that NaCl is effective for oviposition control of gravid females when laying their overwintering eggs. Our results showed that a 0.5% NaCl solution is effective for use as an oviposition repellent against Ae. albopictus females.
