Developing and incorporating new vector control tools based on chemical ecology are necessary to reduce mosquito disease transmission. Chemical substances that mediate the selection of oviposition sites by adult female mosquitoes have been identified. Salvia brandegeei and Salvia pachyphylla were shown to have an oviposition-deterrent effect in Ae. aegypti resistant to temefos and pyrethroids. In addition, both plant extracts produced a high percentage of inhibition in egg-hatching.
