A new mutation, designated as psi-mutant, affecting the timing of the circadian oviposition rhythm was discovered the in natural population of Aedes krombeini . This mutation advanced the phase of the oviposition median in an entraining light-dark cycle of 12:12 h by ca. 7.0 h and shortened the free running period t in constant darkness (DD) by ca. 4.0 h. Early oviposition in psi-mutants was also observed when while free-running in DD they were subjected to 24-h temperature cycles (29°C for 12 h and l8°C for l2 h). When the phase response curves (PRCs) for light pulses against DD as background were measured, the PRC for the psi-mutant had large delaying phase shifts, whereas, that of the wild strain had small delaying phase shifts. |
