Field evaluation of an insect growth regulator, pyriproxyfen, against Aedes togoi larvae in brackish water in South Korea.
The granular formulation of 0.5% pyriproxyfen was evaluated for inhibition of emergence of Aedes togoi in brackish water of rock pools near a coastal area in Pusan, South Korea. Complete adult emergence inhibition in 4th-stage larval and pupal isolations was affected from 5-40 days at 0.05 mg/l after treatment. Most inhibition rates were over 80% throughout the test period at all test concentrations of pyriproxyfen except 61.0% and 67.5% of inhibition rates at 0.01 mg/l at 52 days and 62 days after treatment, respectively. It is suggested that the dose for successive control of Ae. togoi for long-term might be 0.05-0.1 mg/l of 0.5% pyriproxyfen granules.
