Response of B. germanica females to transient social interaction during the photophase and scotophase.

Newly-eclosed females were reared either in social isolation (negative control) or paired with a conspecific female (positive control) for the entire 6-day-long experiment. Other females were transiently paired 6 h daily either in the middle of the photophase or the middle of the scotophase. Some females were transiently paired for 1 or 2 h daily in the middle of the scotophase. Mean basal oocyte length ± SE Different letters above the bars indicate significant differences among treatments (ANOVA, LSD, F_{5, 121} = 13.69, P<0.0001).
