Similar variations at all three storage durations occurred for both OV and CG wet weights (see Table I); , both organs were large in June-August, significantly smaller in September-December, and increased significantly in weight in January-March. MO production and OV and CG development at LD25 seemed to be correlated with mating status during January-March but not September-December. As shown in Table II, organ weights in mated and virgin females did not differ significantly after storage duration in September December. Similarly, although MO production was apparently twice as high in mated females at 10 days in September-December, that relationship was not evident at 5 or 20 days. By contrast, in mated females TABLE I Female monarch ovarian and colleterial gland development at LD25. Data expressed as mean wet weight in mg ± SEM; n, in parentheses, are the same for both organs; ovary (OV) values are weights of single ovaries; CG = colleterial glands; days indicate duration of storage at LD25.
