  • Circadian rhythms in Megachile rotundata (Fabricius) and Nomia melanderi Cockerell

    Creator:
    Tweedy, David Graham
    Abstract:
    The purpose of the study was to determine an emergence rhythm, its period, and the developmental stages susceptible to emergence synchronization in the leafcutter bee Megachile rotundata (Fabricius). An attempt was made to determine if an oxygen consumption rhythm was present in the pupal and adult stages of the alkali...

  • Circadian rhythms in Megachile rotundata (Fabricius)

    Creator:
    Tweedy, David Graham
    Abstract:
    The rhythms of emergence, oxygen consumption, and activity were studied in Megachile rotundata with the object of comparing the results to the major properties of the biological clock such as temperature independence, susceptibility to light synchronization, and entrainment. A further objective was to compare the three rhythms to determine if...
