Synthesis and bio-evaluation of aryl hydrazono esters for oviposition responses in Aedes albopictus
2011
Abstract A novel series of aryl hydrazono esters (AHE) (1–13) were synthesized (yield 76–98%) to study the oviposition responses in Aedes albopictus (Skuse) mosquitoes for the first time. At a concentration of 10 μg ml −1 in dual choice experiment, among the screened compounds, AHE-12 showed remarkable oviposition attractant activity with an oviposition activity index (OAI) of +0.299 (greater than 95% confidence limit) comparable to p -cresol (OAI +0.320) which is well-reported oviposition attractant for Aedes aegypti . Conversely, AHE-10 exhibited highest oviposition deterrent activity with OAI −0.247. The possible utilization of these compounds will be in integrated vector management strategies.
