Immunolocalization of general odorant-binding protein in antennal sensilla of moth caterpillars. Abstract Text:

M Laue,

Antennae of Bombyx mori and Helicoverpa armigera larvae were immunolabelled with antisera raised against the pheromone-binding protein or the general odorant-binding protein 2 of Antheraea polyphemus to assign the expression of these proteins to individual sensilla and to compare the localization pattern with that in sensilla of adult moths. Specific labelling of antennal sensilla was only obtained with the antiserum against general odorant-binding protein 2. Among the few sensilla present on the antenna the three large sensilla basiconica, which are suspected to be olfactory in function, were labelled. These sensilla are compound sensilla consisting of several sensillum units which form a common sensory hair. The hair is single-walled and pierced by many pores. Labelling of sensillum compartments was the same as in sensilla of adults. Prominent labelling of the sensillum lymph is accompanied by labelling of secretory organelles in the two outermost auxiliary cells and of endocytotic pathways in all sensillum cells. The results suggest that general odorant-binding protein is expressed in single-walled multiporous sensilla of presumed olfactory function on the antenna of moth larvae. The overall identity of the localization pattern for general odorant-binding protein between larval and adult sensilla implies a similar role of these proteins in olfactory stimulus transduction.
