The resultant radioactivities of yellow-fever mosquito, Aedes aegypti (L.) adults, when instar III and IV larvae were treated with P32, have been studied. Instar III larvae incorporated comparatively greater amounts of radioactivity but also lost large amounts during development in distilled water. Instar IV larvae retained a considerable amount of the incorporated radioactivity during development under similar conditions. Synchronously pupating-larvae yielded adults with comparatively less variation in radioactivity. There was little but measurable transfer of radioactivity from a radioactive male to a normal female during her first copulation. |
