“…Las variedades de caña mas atacadas por mosca pinta (CP 72-2086 y MEX 69-290) son las que producen una menor cantidad de (z)-3-Hexen-1-ol y 1-Octen-3-ol. El (z)-3-Hexen-1-ol se relaciona directamente con aromas de hojas verdes, en las gramíneas se liberan volátiles de las hojas dañadas inmediatamente después del comienzo de daño por alimentación o incluso inmediatamente después de que la planta es dañada mecánicamente (Röse y Tumlinson, 2004;D'Auria et al, 2007), se forman por la degradación enzimática y la reducción de ácido graso (Cortés et al, 2005) y se ha evaluado como atrayente de las hembras de enjambre de otoño (Hyphantria cunea) utilizando la técnica de electroantenograma (Tang et al, 2012). Se demostró que este compuesto de origen vegetal emite señales químicas que atraen insectos benéficos a los cultivos (Gurr y Reynolds, 2009).…”

Este trabajo analizó las volátiles mediante la obtención de extractos de hojas verdes de caña de azúcar en estado maduro de ocho variedades de caña de azúcar y de dos especies de pastos mediante hidrodestilación con una trampa Clevenger. Las variedades de caña de azúcar utilizadas en este estudio fueron: CP 72-2086, MEX 69-290, RD 75-11, ITV 92-1424, MEX 79-431, L 77-50, COLPOS CT MEX 05-223, COLPOS CT MEX 05-204. Los pastos evaluados fueron: zacate peludo (Rottboellia cochinchinensis) y pasto estrella africana (Cynodon nlemfuensis). En el material evaluado se encontraron tres compuestos principales, estos son: (Z)-3-hexen-1-ol, 1-octen-3-ol y fitol. Estos compuestos fueron más representativos en las variedades CP 72-2086 y MEX 69-290. El compuesto con mayor frecuencia fue el (Z)-3-hexen-1-ol, que estuvo presente en siete variedades al igual que en los dos pastos evaluados. La abundancia de (Z)-3-hexen-1-ol en las muestras de las variedades de caña de azucar varia desde 20.35% hasta 57.36%, la mayor cantidad de (Z)-3-hexen-1-ol se detecto en el pasto estrella africana con una abundancia de 59.69%.

“…The head space absorption method was used for collecting volatile blends from substrates, following previous protocols 36 37 . Odor compounds were collected at 25 °C using 0.3 g of super-Q absorbent (80/100, Alltech, Deerfield, IL, USA) for 24 h at 50 ml/min air flow rate and eluted with 1.5 ml hexane solvent.…”

“…GC-EAD was used for the identification of bioactive compounds in female flies. Antennae were processed following standard procedures by cutting both extremes of flagella and immediately mounted with two glass capillary Ag/AgCl electrodes containing Kaissling saline (glucose 354 mmol/l, KCl 6.4 mmol/l, KH 2 PO 4 20 mmol/l, MgCl 2 12 mmol/l, CaCl 2 1 mmol/l, NaCl 12 mmol/l, KOH 9.6 mmol/l, pH 6.5) 36 37 and an identical GC column was used under the same temperature program as GC-MS with detector at 230 °C. Electroantennogram signals and flame ionization detector (FID) responses from the GC were recorded simultaneously.…”

Oviposition attractants for the house fly Musca domestica have been investigated using electrophysiological tests, behavioural assays and field tests. Volatiles were collected via head space absorption method from fermented wheat bran, fresh wheat bran, rearing substrate residue and house fly maggots. A Y-tube olfactometer assay showed that the odor of fermented wheat bran was a significant attractant for female house flies. Bioactive compounds from fermented wheat bran for house fly females were identified by electrophysiology and mass spectrophotometry and confirmed with standard chemicals. Four electrophysiologically active compounds including ethyl palmitate, ethyl linoleate, methyl linoleate, and linoleic acid were found at a proportion of 10:24:6:0.2. Functional imaging in the female antennal lobes revealed an overlapped active pattern for all chemicals. Further multiple-choice behavioural bioassays showed that these chemicals, as well as a mixture that mimicked the naturally occurring combination, increased the attractiveness of non-preferred rearing substrates of cotton and maize powder. Finally, a field demonstration test revealed that, by adding this mimic blend into a rearing substrate used to attract and breed house flies in West Africa, egg numbers laid by females were increased. These chemicals could be utilized to improve house fly production systems or considered for lure traps.

Volatile organic compounds (VOCs) were collected from damaged and intact mulberry leaves (Morus alba L., Moraceae) and from Hyphantria cunea larvae by headspace absorption with Super Q columns. We identified their constituents using gas chromatography-mass spectrometry, and evaluated the responses of male H. cunea antennae to the compounds using gas chromatography-flame ionization detection coupled with electroantennographic detection. Eleven VOC constituents were found to stimulate antennae of male H. cunea moths: β-ocimene, hexanal, cis-3-hexenal, limonene, trans-2-hexenal, cyclohexanone, cis-2-penten-1-ol, 6-methyl-5-hepten-2-one, 4-hydroxy-4-methyl-2-pentanone, trans-3-hexen-1-ol, and 2,4-dimethyl-3-pentanol. Nine of these chemicals were released by intact, mechanically-damaged, and herbivore-damaged leaves, while cis-2-penten-1-ol was released only by intact and mechanically-damaged leaves and β-ocimene was released only by herbivore-damaged leaves. Results from wind tunnel experiments conducted with volatile components indicated that male moths were significantly more attracted to herbivory-induced volatiles than the solvent control. Furthermore, male moths' attraction to a sex pheromone lure was increased by herbivory-induced compounds and β-ocimene, but reduced by cis-2-penten-1-ol. A proof long-range field trapping experiment showed that the efficiency of sex pheromone lures in trapping male moths was increased by β-ocimene and reduced by cis-2-penten-1-ol.
