Resumo: | Octenol (1-octen-3-ol) is a kairomone used by haematophagous insects to locate their vertebrate hosts. However, effect of 1-octen-3-ol on Lutzomyia (Lutzomyia) longipalpis (Lutz &amp;amp; Neiva) has never been studied. The present work evaluated the electrophysiological (EAG) responses of female L. (Lutzomyia) longipalpis. Air current, air pulse and solvent (hexane) pulse were used as control stimuli. The logarithmic concentrations of 1-octen-3-ol 10 a 10(6) etag/50µl of solvent were tested. Significant olfactory responses were observed in the concentration of 1-octen-3-ol from 10³ etag/50ul with the greatest response at concentration of 10(6) etag/50ul (-3,33mV). Dose-dependency was observed, as the concentration increased, so did the electrophysiological response. These results demonstrated, for the first time, that L. longipalpis, can detect the presence of 1-octen-3-ol in air current. The possible use of 1-octen-3-ol as kairomone for this species is discussed.
