“…These observations are in agreement with behavioral responses of R. palmarum to odors in the laboratory and in the field, males and females respond with the same sensitivity to hynchophorol and sugarcane juice in a four-armed olfactometer (Said et al, 2003).…”

“…For instance, ORNs are often excited by some compounds and inhibited by others (e.g. Andersson et al, 2009;Hallem and Carlson, 2006;Said et al, 2003), and responses to compound blends cannot always be predicted based on the responses to the individual blend constituents (Getz and Akers, 1997;Ochieng et al, 2002;Party et al, 2009). Furthermore, insects typically have two or more ORNs co-compartmentalized within a sensillum.…”

SUMMARYWe identified several compounds, by gas chromatographic-electroantennographic detection (GC-EAD), that were antennally active in the bark beetle Ips typographus and also abundant in beetle-attacked spruce trees. One of them, 1,8-cineole (Ci), strongly inhibited the attraction to pheromone in the field. Single-sensillum recordings (SSRs) previously showed olfactory receptor neurons (ORNs) on I. typographus antennae selectively responding to Ci. All Ci neurons were found within sensilla co-inhabited by a pheromone neuron responding to cis-verbenol (cV); however, in other sensilla, the cV neuron was paired with a neuron not responding to any test odorant. We hypothesized that the colocalization of ORNs had a functional and ecological relevance. We show by SSR that Ci inhibited spontaneous activity of the cV neuron only in sensilla in which the Ci neuron was also present. Using mixtures of cV and Ci, we further show that responses to low doses (1-10ng) of cV were significantly reduced when the colocalized Ci neuron simultaneously responded to high doses (1-10mg) of Ci. This indicated that the response of the Ci neuron, rather than ligand-receptor interactions in the cV neuron, caused the inhibition. Moreover, cV neurons paired with Ci neurons were more sensitive to cV alone than the ones paired with the non-responding ORN. Our observations question the traditional view that ORNs within a sensillum function as independent units. The colocalization of ORNs might sharpen adaptive responses to blends of semiochemicals with different ecological significance in the olfactory landscape.

“…La técnica de SPME ha sido empleada principalmente para estudios en coleópteros (Said et al, 2003;Cai et al, 2007;Yasui et al, 2008;Arakaki et al, 2009), y recientemente para la identificación de sustancias emitidas por el tefrítido Anastrepha serpentina (Wiedemann) (Robacker et al, 2009). …”

“…SPME-gas chromatography (GC) was first applied in 1995 as an alternative method for the study of airborne insect pheromones (Malosse et al, 1995), and since then, SPME has been employed in sampling of insect volatiles, particularly in beetles (Said et al, 2003;Cai et al, 2007;Yasui et al, 2008;Arakaki et al, 2009). SPME has also been recently employed in the identification of chemicals emitted by Anastrepha serpentine (Robacker et al, 2009), but its use in medfly volatile collection has not yet been reported, as far as we know.…”
