Spatial repellency and other effects of transfluthrin and linalool on Aedes aegypti and Aedes albopictus

ABSTRACTIn the present study, the effects of two spatial repellents (SR) were determined forAedes aegypti andAe albopictus, the main vectors of dengue, Chikungunya, and Zika fever. The modular high ‐throughput screening system (HITSS) was used to evaluate the response of both species to transfluthrin and linalool SR at different concentrations. The highest spatial repellency results forAe. aegypti were obtained by transfluthrin to 0.001% with 37.50 ± 4.33%, and for linalool to 10% with 77.50 ± 3.90%. ForAe. albopictus, the highest spatial repellency percentages for transfluthrin 0.01% were 45.00 ± 3.78%, and linalool at 1% and 10% were 56.25 ± 7.06% and 56.25 ± 6.46%, respectively. Transfluthrin caused high levels of mortality with 71.25 ± 6.66%, 79.75 ± 8.65%, and 100% toAe. aegypti and 70.00 ± 5.98% and 98.75 ± 0.82% toAedes albopcitus. With the results of this study, we concluded that both the transfluthrin and linalool could be used as protection measures against the bite ofAe. aegypti andAe. albopictus in the integral strategies for the control of vectors in Mexico.
