Table 1. Differences in the rates of incorporation of oleic acid into DG and TG between larval and adult stages of M. sexta.
The distribution of radiolabeled oleic acid between the glycerolipids of fat body and hemolymph was determined 4h after injecting the insects with [3H]-oleic acid. Data are expressed as percent of total radioactivity recovered in hemolymph or fat body +/- SD (n= 4 insects). Other lipids include radioactivity found in phospholipids, MG and non-esterified fatty acids.
| % of Total dpm | TG (dpm %) | DG (dpm%) | Other Lipids (dpm %) | ||
|---|---|---|---|---|---|
| Larva (5th Instar, day 2) | Hemolymph | 23.5 ± 2.5 | 1.1 ± 0.8 | 21.3 ± 0.9 | 1.1 ± 0.2 |
| Fat Body | 76.5 ± 2.5 | 67.6 ± 2.0 | 4.7 ± 0.7 | 5.5 ± 1.5 | |
| Adult (day 2) | Hemolymph | 65% ± 5.8 | 0.4 ± 0.3 | 58.2 ± 4.3 | 6.2 ± 1.2 |
| Fat Body | 35% ± 5.8 | 25.4 ± 3.3 | 6.7 ± 0.9 | 3.2 ± 0.5 | |
