Host recognition via chemosensory organs. (A) Oviposition responses of Lyonia race females after ablating the following chemosensory organs, A: antennae; A (one): one of pair of antennae; FT: foreleg tarsi; A-FT: antennae and foreleg tarsi; None: untreated. Different letters indicate statistically significant differences among the treatments by Fisher’s exact test, p < 0.01. Numbers in parentheses represent the number of tested animals. (B) SEM images of distal and middle portion of female and male antennae. Scale bars: 10 μm. (C) Middle portion of antennae without scales. Scale bars: 25 μm. (D) Sensilla chaetica of female. Scale bar: 2 μm for whole image of sensillum and 0.5 μm for the image of tip. Symbols indicated sensilla chaetica (asterisk), sensilla basiconica (filled circle) and sensilla trichodea (filled arrowhead).
