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...
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...
