The study provides the details of the ethology of Megachile rotundata
(Fabricius), and presents preliminary observations on its
foraging and nesting behavior. Development from prepupae to adults
proceeds most rapidly at 32 degrees C., and is retarded when held
at lower and higher temperatures.
Male behavior is distinct from that...
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
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...
