Abstract: Sinitinea pyrigolla is one of the important xylophagous insect in pear tree. Laboratory studies found that the lifespan of adult Sinitinea pyrigolla were 7~9 days. The courtship and mating mainly occurred within 2 days after eclosion. Daily activity peak mainly occurred at 19:00-22:00. Daily courtship mainly occurred from 19:00 to 22:00, except this period time, courtship also occurred in the morning from 3:00-6:00. There were two peaks of daily mating. The first peak appeared at 17:00-23:00 as the main mating phase. The second peak was small, appeared at 6:00-9:00. The average mating duration was 89 min, which varied from 30 min to 180 min. This study is helpful in understanding the biological characteristics of Sinitinea pyrigolla and provides guidance for the control and prevention.
