Electroantennogram, flight orientation and oviposition responses of Anopheles stephensi and Aedes aegypti to a fatty acid ester-propyl octadecanoate

► We study olfaction-mediated behavioral responses of Anopheles and Aedes to PO. ► Dose dependent EAG responses at 10−5 g were recorded from both mosquito species. ► 80% of Stephensi, and 77% of Aegypti females were trapped at 10−5 g odor plume. ► Residual activity of PO effervescent tablet lasted for up to 1 week at 1 and 10 mg/L. ► PO can be used in ovitraps for monitoring of An. stephensi and Ae. aegypti.
