A laboratory evaluation of alcohols as attractants for the sandfly Lutzomyia longipalpis (Diptera:Psychodidae)

Abstract

BackgroundThe potential attraction from 1-octen-3-ol for sandflies has been documented; however, studies using other primary alcohols are limited.FindingsWe used a wind tunnel to compare the activation and attractive behaviors in male and female Lutzomyia longipalpis using 1-octen-3-ol and three additional alcohols, 1-octanol, 1-heptanol and 1-nonanol at three different concentrations: neat (100%) and diluted in hexane (10% and 50%). The compounds 1-octen-3-ol and 1-nonanol induced a clear concentration-dependent activation and attraction response in females. In males, 1-octen-3-ol, 1-nonanol and 1-heptanol yielded the same results.ConclusionsL. longipalpis is attracted to 1-octen-3-ol, 1-nonanol and 1-heptanol, which are found in many plant volatiles.

DNA barcode for the identification of the sand fly Lutzomyia longipalpis plant feeding preferences in a tropical urban environment

“…Magalhaes-Junior et al . 43 additionally verified that volatile plant compounds, 1-octen-3-ol, 1-nonanol and 1-heptanol, can act as attractive factors for insects from the L. longipalpis species. It is worth noting that the compounds 1-octen-3-ol 44 and 1-nonanol 45 have been identified in different species belonging to the Fabaceae family.…”

Evolutionarily conserved odorant receptor function questions ecological context of octenol role in mosquitoes

“…Octenol is used as an aggregation pheromone in the sawtoothed grain beetle, Oryzaephilus surinamensis 42 and as a plant attractant in the black blowfly, Phormia regina 43, the legume pod borer, Maruca vitrata 44, the Grapevine Moth, Lobesia botrana 45, the European grape berry moths, Eupoecilia ambiguella 46 and the sandfly Lutzomyia longipalpis 47. It is also used as a compost attractant for the phorid fly, Megaselia halterata 48 and as an avoidance cue for the parasitoid Lariophagus distinguendus 49.…”

Effectiveness of Pleurotus eryngii (King Oyster Mushroom) Extract for Killing Larvae and Attracting Adult Mosquito Vectors in Samut Songkhram Province of Thailand

“…The use of odor in traps is one of the most important tools used to increase the effectiveness of mosquito control. Octenol is a powerful mosquito attractant [21], but it is expensive. It attracts mosquitoes because it emanates from humans and animals that would serve as prey for blood-feeding female mosquitoes [22].…”
