Fig. 2. Age-dependent in vivo hydrocarbon (HC) deposition in the ovary and epicuticle in relation to the reproductive cycle. [³H]3,11-Dimethylnonacosane (21.46 kBq) was injected in 0.4 µl of hexane into the hemocoel of females of various ages, and uptake of [³H]3,11-dimethylnonacosane by the ovary (A) and epicuticle (B) was assayed 24 h later. Values are means ±1 S.E.M.; some error bars are obscured by the symbol. N=8 for each mean, except on day 0, where N=10, day 1, where N=13, day 6, where N=6, and day 8, where N=9.
