摘　　要：采用室内饲养的方法对贵州地区核桃扁叶甲的生活史及生物学特性进行了观察,研究其发生发展规律。结果表明:核桃扁叶甲在贵州地区1年发生2代,第1代为4月中旬至6月下旬,第2代为5月中旬至次年4月上旬。核桃扁叶甲交配和产卵主要集中在白天,交配高峰期在11:00—15:00,13:00时最高,产卵高峰期主要集中在14:00—16:00,最高峰为15:00。In order to have a clearer understanding of the occurrence and development of Gastrolina depressa in Guizhou province,we studied the life history and biological characteristics of Gastrolina depressa.The results showed that:Gastrolina depressa occurred twice one year in Guizhou.The first generation was from mid-april to late June,and the second generation was from mid-may to early April.The mating and spawning of Gastrolina depressa were mainly concentrated in the daytime.The mating behavior was concentrated at 11:00—15:00,which reached the peak at 13:00.The spawning behavior was concentrated at 14:00—16:00,which reached the peak at 15:00.
