Outline of Final Research Achievements

Locomotor activities and circadian rhythms of long-reared (more than 35 years) and wild populations of Tribolium castaneum (Coleoptera: Insect) were compared. We found significantly higher percentages of arrhythmic individuals in the long-reared population compared to the population caught in the wild. Only males were compared because no difference between the sexes was found in the percentage of arrhythmic beetles. Next, comparison of the circadian rhythms of wild and long-reared beetle populations showed no significant difference between the populations. The result suggests that the circadian rhythm in T. castaneum has been lost during long-rearing under an artificial condition. We will discuss arrythmicity in organisms.

Academic Significance and Societal Importance of the Research Achievements

生物個体のリズムの有無を判別するには統計学的な問題のあることがわかった。それはリズムは連続的な形質であり、1/0で分類できないためと考えられた。そこで、リズムの有無ではなく、リズムの強さを指標として行動生態学の解析を行った。コクヌストモドキでは行動形質を育種した系統間ではリズムの強さに一貫した差は見られず、オオツノコクヌストモドキではリズムの強さに遺伝変異があり、それはメスに比べてオスでより強かった。これはオス同士闘争が必要な昆虫では、リズムに関連した形質にも性差が見られることを示唆している。
