Function of the antennae in receiving social cues that stimulate reproduction.

<p>Newly-eclosed females were ice-anesthetized and the flagellum of each antenna was ablated just distal to the pedicel. Socially isolated intact females represent the negative control, and intact females that were socially paired represent the positive control. Other females received one of the following treatments: (1) isolated-housed antennectomized female; (2) an intact female paired with an antennectomized female; and (3) paired antennectomized females. Mean basal oocyte length ± SE. ANOVA: <i>F</i>_{5, 122} = 52.29, <i>P</i><0.0001. Different letters above the bars indicate significant differences among treatments (LSD, <i>P</i><0.05).
