“…The main constituents of male volatile compounds include geranyl acetate, (E,E)-R-farnesene, and ethyl (3E)-3-octenoate, which is consistent with the results of similar studies [26]. Relationships between compounds structures and emission patterns were the similar positions in some compounds like nonane and octanal [27]. In fact, this kind of experiment was carried out with C. capitata and the conditions (age, RH, temperature, light) could also be an impact on the detected VOCs.…”

The Mediterranean fruit fly (Medfly) Ceratitis capitata (Diptera: Tephidae), as most of the Tephritidae species, is a pest of great economic importance around the world. For Integrated Pest Management (IPM) and biological pest management purposes, this research will investigate characterization of the broadest possible range of volatile organic compounds and the possible changing trends of volatile biological emissions during development stages of insect. During the last years, many types of research have been done to understand chemical communications between pest-pest interactions and about the insect responses to specific volatile organic compounds. An early comparison of the VOCs emitted from larvae, pupae and adult was performed. Our research focuses on the comparison of volatile compounds emitted from a different stage of Medfly using stable isotope 13 C 6 -glucose. Gas Chromatography (GC) technique coupled with Flame Ionization Detection (FID) and gas chromatography with mass spectrometry (GC-MS) for identification of VOCs was employed. Head Space-Solid Phase Micro Extraction HS-SPME method with Three-phase fiber 50/30 µm divinylbenzene/carboxen/ polydimethylsiloxane (DVB/CAR/PDMS) was used. The results showed that there are different chemicals emitted in a different stage of Medfly (Larvae, pupae, and adults M/F) especially in the adult stage. GC-MS detected 27 compounds from larvae, 23 compounds from pupae and 29 compounds from adults. These different VOCs emitted in different stages of Medfly were clearly displayed, and a broad range of emitted volatile compounds was successfully described. The characterization of release patterns could be useful tool for the selection of compounds and for further investigated in biological studies to understand of the key semi-chemicals involved in medfly behaviour.

“…The main constituents of male volatile sampling were geranyl acetate, (E,E)-α-farnesene and ethyl (3E)-3-octenoate, which is consistent with the results of similar studies (Baker et al, 1985;Jang et al, 1989;Flath et al, 1993;Light et al, 1999), but our analysis added 2-ethylhexanoic acid to these main components. Jang et al (1989) reported that the only compounds attributable to the presence of females were some short-chain aldehydes at trace levels.…”

“…Later, Flath et al revised, in 1993, the composition of virgin male medfly volatiles, and the differences in abundance of the major compounds according to two factors: age and time of day. These reported works (Jang et al, 1989;Flath et al, 1993) agree with the three major components present in male samples: ethyl-(E)-3-octenoate, geranyl acetate and (E,E)-α-farnesene, and many efforts have been conducted to formulate these key compounds for field testing (Heath et al, 1991;Flath et al, 1993;.Jang et al, 1994;Jang et al, 1996;Light et al, 1999).…”

“…This fact could be explained by the different technique applied for volatile collection, as mentioned above, or other experimental factors (e.g. sampling duration or air-flow) as pointed out by other authors (Flath et al, 1993). Actually, taking into account that this kind of experiences were carried out with C. capitata mass-rearing colonies, the rearing conditions could also have influence on the detected compounds.…”

“…Estos últimos estudios coinciden en los tres componentes mayoritarios de las emisiones de machos vírgenes de C. capitata: (E)-3-octenoato de etilo, acetato de geranilo y (E,E)-α-farneseno. Se han realizado formulaciones de estos compuestos para su ensayo en campo (Heath et al, 1991;Flath et al, 1993;Jang et al, 1994;Light et al, 1999), pero no se ha conseguido una buena actividad atrayente con ellos. Es posible que la ausencia de alguno de los compuestos minoritarios, no incluidos en la mezcla, sea clave para conseguir un buen poder atrayente.…”

A novel and versatile synthetic approach to the preparation of (E)‐non‐6‐en‐1‐ol, a sex pheromone of the Mediterranean fruit fly, Ceratitis capitata, is presented. This pheromone can be viewed as potential active component for lures designed to control and eradication of Mediterranean fruit fly. The described protocol is a six‐step reaction sequence producing the desired compound with 28% overall yield from commercially available and inexpensive starting material and total E stereoselectivity of the double bond present in final structure. The key to the success of the presented strategy is application of lithiated α‐allylphosphoramido carbanions and their reaction with halogenated acetals. © 2010 Wiley Periodicals, Inc. 21:139–147, 2010; Published online in Wiley InterScience (http://www.interscience.wiley.com).
