抄録

The circannual pupation rhythm of Anthrenus verbasci is entrained to an environmental cycle by changes in photoperiod. Exposure of larvae reared under short-day conditions to long days induced a clear phase delay of the circannual rhythm. There was no notable difference in the initial phase or period of the circannual rhythm among four geographically distinct populations of A. verbasci in Japan: Takanabe (32.1°N), Osaka (34.7°N), Sendai (38.3°N), and Sapporo (43.1°N) populations. The range of photoperiodic changes effective for phase delay in the circannual pupation rhythm was compared among the four populations. Although larvae did not show a typical threshold response, but responded quantitatively to the photophase duration in intermediate conditions, the critical daylengths were calculated as those under which the pupation was delayed by 50%: 12.8 h in the Takanabe population, 13.2 h in the Osaka population, and 13.6 h in the Sendai and Sapporo populations. Thus, the critical daylength for entrainment of the circannual rhythm in A. verbasci was correlated to the habitat latitude, but the differences among the populations were much smaller than those reported in photoperiodism for induction of diapause in various insects. Consequently, the difference in the pupation time among the four geographic populations was very small under the natural photoperiod in Osaka at 20°C, and absent under the natural photoperiod and temperature in Osaka. These results suggest that A. verbasci survives and successfully produces the next generation in different geographic regions without changing the parameters of the circannual rhythm.
