摘要

The life history and adult daily rhythm of Gilpinia yongrenica Xiao et Huang in Guizhou Province were observed and recorded.The results showed that there were three generations of G.yongrenica in Guizhou area;the first generation occurred from late March to middle July;the second generation occurred from early June to middle October;and the third generation occurred from middle September to late April.The ratio of male to female was 5.75∶1,and the emergence rate was 88.25%.The emergence of adults changed significantly with time,and the peak emergence period was at 12:00-13:00.The resting behavior accounted for the largest proportion in daily time distribution of adult behavior;followed by moving behavior and spawning behavior;and the mating behavior accounted for the smallest proportion.The moving behavior mainly occurred during the daytime,which reached the peak at 8:00-11:00.The resting behavior mainly occurred at 19:00-7:00,with the maximum reaching 100%.The mating behavior was concentrated at 12:00-13:00,which reached the peak at 13:00(19.5%).The spawning behavior mainly occurred at 14:00-15:00,and reached the peak at 14:00(42.1%).
