Abstract:
:Multicomponent pheromone systems are common in many insect species. As our knowledge about the number of different chemical compounds actually involved in a particular communication system increases, so too does the need for an efficient neural mechanism for the encoding of behaviorially relevant odor compounds. Here we consider the electrical activity of olfactory receptor neurons in a subset of the individual pheromone-sensitive sensilla on the antennae of male cabbage looper moths (Trichoplupia ni). Responses to single- and multiple-component stimuli, drawn from seven behaviorally active compounds, were obtained at several different intensities. Some blends elicited electrical responses which were not readily predicted from a knowledge of the receptor neuron's response to individual components.
