Disease relevance of 1-OCTEN-3-OL

  • The effect of 1-octen-3-ol (octenol) on catches of estuarine biting midges in encephalitis vector surveillance (EVS) traps was examined in southeastern Queensland. Octenol by itself was not attractive but appeared to act as a synergist with CO2 to increase catches of most species [1].
  • Does 1-octen-3-ol enhance trap collections of Japanese encephalitis virus mosquito vectors in northern Australia [2]?

High impact information on 1-OCTEN-3-OL


Chemical compound and disease context of 1-OCTEN-3-OL

  • Encephalitis vector surveillance (EVS) traps were used to study the attractant effect of CO2 and 1-octen-3-ol (octenol) on mosquitoes at 2 different locations in southeast Queensland. Octenol alone was only slightly attractive for Aedes vigilax [8].

Biological context of 1-OCTEN-3-OL

  • However, both compounds provoked negative chemotaxis of conspecific millipedes in a Y-tube olfactometer, especially 1-octen-3-ol, which was active at a dose equivalent to the content of a single millipede [9].

Anatomical context of 1-OCTEN-3-OL

  • Volatiles from tick exuviae plus feces and from dead ticks also attracted A. variegatum, suggesting that 1-octen-3-ol may contribute to the aggregation response of Amblyomma spp. on such substrates [10].

Associations of 1-OCTEN-3-OL with other chemical compounds

  • Although B. microplus responded to the same synergistic mixture of volatiles as I. ricinus, it showed significant higher sensitivity to the cattle-associated compounds 1-octen-3-ol and 2-nitrophenol and this might contribute to its host-specificity [11].
  • The major volatile components of the SDE extracts obtained at 1.5 h and pH 6.0 were gamma-caryophyllene, 1-octen-3-ol, 2-hexenal, germacrene B, and aromadendrene II, with corresponding peak areas of 44.14, 15.6, 9.86, 5.24, and 4.01%, respectively, and major antibacterial components were 1-octen-3-ol and 2-hexenal [12].
  • The presence of small amounts of compounds such as ethyl hexanoate, 1-octen-3-ol, nonanal, and ethyl 2-methylbutanoate could justify the particular odorous profile of the plant, resembling the aroma of milk and other dairy products such as mozzarella [13].
  • Key odorants of fennel seeds determined by gas chromatography-olfactometry (GC-O) showed similar patterns when applying SDE and SFE. trans-Anethole (anise, licorice), estragole (anise, licorice, sweet), fenchone (mint, camphor, warm), and 1-octen-3-ol (mushroom) were the most intense odor compounds detected in fennel extracts [14].
  • Many of the compounds shown to attract Glossina have been tested with mosquitoes, and one of these, 1-octen-3-ol, attracts female mosquitoes of a number of species, but only in the presence of CO2 [15].

Gene context of 1-OCTEN-3-OL

  • Additional studies with deer models baited with CO2, 1-octen-3-ol and Deer Trail Scent, and muzzle and nostrils treated with insect adhesive, revealed that only C. apicata Bennett & Sabrosky larviposited onto the lips/lower muzzle; C. jellisoni, by contrast, larviposited into the nostrils [16].
  • 1-Octen-3-ol with and without ammonia were evaluated as attractants in canopy traps for Haematopota pluvialis L., Hybomitra expollicata Pand., and Morellia spp [17].
  • These included 1-octen-3-ol, 6-methyl-5-hepten-2-one, (Z)-3-hexen-1-ol, naphthalene, and all EAG active compounds identified from urine [18].
  • Lure-baited traps consisted of one ABC PRO insect suction trap (fitted with a 30 by 30-mesh polyester screen bag) baited with carbon dioxide (500 ml/min) and a 4:1:8 mixture of 1 octen-3-ol, 3-n-propylphenol, and 4-methylphenol (5.39 +/- 0.54 mg/h) placed in each of three backyards [19].
  • Octenol (1-octen-3-ol), acetone, 4-methylphenol, 3-n-propylphenol, and other potential attractants (human urine, stable fly faeces), as well as guiacol, creosol (potential repellents), were tested as baits for biting flies in North America using standard phthalogen blue IF3GM cotton Nzi traps, or similar commercial polyester traps [20].
