Life-cycle of Suidasia medanensis (=pontifica) (Acari: Suidasiidae) under laboratory conditions in a tropical environment.

The life cycle of Suidasia medanensis (=pontifica) was studied under laboratory conditions at 26 degrees C and 86% relative humidity. Freshly laid eggs were observed until they developed into adults and the periods between stages were recorded. Production of eggs by mated females was monitored until they died. The eggs required an average of 12.6 +/- 0.6 days to develop into adults. Mean longevity of mated females and males was similar (48.6 +/- 13 and 49.1 +/- 20 days, respectively). The conditions used in this study may be considered optimal for in vitro culture of S. medanensis.
