Phlebotomine sand flies are often captured with human bait and/or light
traps, either with or without an animal bait. More recently, synthetic
attractants have been used as bait in traps to improve the capture of
phlebotomine sand flies as well as other insects of medical and
veterinary importance. The aim of the present study was to evaluate the
effects of the kairomone 1-octen-3-ol (octenol) and the synthetic human
odor BG-Mesh LureTM (BGML - lactic acid, caproic acid and ammonia)
baited in modified CDC light traps on the capture of phlebotomine sand
flies. The experiments followed the 5x5 Latin square design. Among the
species caught, Lutzomyia intermedia apparently presented a
dose-dependent response to octenol. The response obtained with the
BGML, alone or in combination with octenol (5 mg/h), indicated some
degree of attractiveness of these baits to different phlebotomine sand
fly species. Octenol seems to be more attractive to L. intermedia than
to Lutzomyia longipalpis , while the BGML presented a higher success
in capturing L. longipalpis. When the components of the BGML were used
separately, there was no increase in catching the female of L.
intermedia. Apparently, there was no synergistic effect between the
octenol and the BGML. In conclusion, the octenol and the BGML were
demonstrated to be possible baits to attract some phlebotomine sand fly
species.
