“…A major part of the peripheral coding system for the two principal pheromone components resides in neurons responding to both of these components. This condition contrasts with previous studies stating that insect pheromone receptor neurons are highly specific in their response spectrum (Van der Pers and T. Takanashi and others Den Otter, 1978;Liljefors et al, 1987;Akers and O'Connell, 1991;Hansson et al, 1995;Mustaparta, 1997;Wojtasek et al, 1998;Kalinová et al, 2001;Larsson et al, 2002). This has been demonstrated in the closely related European corn borer, O. nubilalis Hansson et al, 1994;Cossé et al, 1995).…”

“…In species having multi-component pheromones, specific neurons for each component are housed either in the same sensillum (e.g., Yponomeuta spp.) (Van Der Pers and Den Otter 1978) or in separate sensilla (e.g., heliothine moths) (Baker et al 2004;Cossé et al 1998). Chemotransduction mechanisms in arthropod sensory neurons are complex, with several second-messenger pathways and ion channels involved (Ache et al 1998), so that interactions between different odorant molecules may be processed at the single sensory cell level.…”

. Dynamic properties of pheromone plumes are behaviorally important in some moths for inducing upwind flight, but little is known about the time-dependent properties of odor transduction or the mechanisms that limit receptor dynamic sensitivity. We stimulated male antennae of two moth species, Cadra cautella and Spodoptera exigua, with pheromone plumes in a wind tunnel while recording electroantennograms (EAG) and concentration of a surrogate plume (propylene, which mimics a pheromone plume) using a photoionization detector (PID). Turbulent plumes were produced by mechanical baffles, creating broad frequency range dynamic concentration changes at the antennae. Frequency response functions and coherence functions between PID and EAG signals were used to measure the dynamic responses of the two species to pheromone blends and individual components. A single time constant filter fitted the responses of both species, but S. exigua was about three times faster than C. cautella. Responses to individual pheromone components were significantly different in S. exigua but not in C. cautella. We also fitted the data with a simple blockstructured nonlinear cascade. This supported the simple filter model but also suggested that the response saturates at an early stage of chemotransduction.

“…Field and laboratory experiments showed that virgin females attracted almost exclusively their conspecific males and that EAG profiles of compounds known to be active as components of pheromones in other Lepidoptera differed among Yponomeuta species (54,55,64). For these same compounds, the more sensitive procedure of single-cell recordings of the sensilla trichodea showed that response spectra in males differed among the five species tested, indicating differing responsiveness to and probable use of different sex pheromones (148). Further refinement and extension to all nine West European representatives of Yponomeuta confirmed these earlier findings and suggested that Zll-14:OAc and EII-14:OAc are important components of the pheromones of most species (146).…”
