説明
The photoperiodic response of two populations of Coccygomimus luctuosus SMITH, a polyphagous internal parasitoid was investigated. In the Hokkaido strain (43°N), diapause was induced in about 90% of individuals at the final larval instar under LD 12:12 at both 17 and 20°C, whereas the diapause rate was much lower at photoperiods longer or shorter than LD 12:12. Although the diapause rate was slightly higher at 17 than at 20°C, the shape of the photoperiodic response curve was not altered by temperature. In the Hyogo (35°N) population, neither short nor long photoperiods induced noticeable developmental arrest at 20°C, while short photoperiods at 17°C induced diapause in a significant number of individuals. Larvae at the penultimate instar were most sensitive to diapause inducing stimuli. Diapause development continued under short photoperiods and the rate of diapause termination depended on photoperiod but not temperature. The difference in temperature-dependent photoperiodic response between the two populations might be related to the habitat climate conditions (severe north vs mild south). The result clearly indicates that the regulation of life cycle in C. luctuosus depends on environmental cues, suggesting 3-4 generations are produced annually in Hokkaido, and 7-8 generations in Hyogo.
