摘要
本文对湟源县林区庭园丽金龟在沙棘上的发生规律和危害特点进行了初步研究。结果表明:庭园丽金龟在湟源县2年发生1代,以3龄幼虫在土壤中越冬,6月下旬成虫羽化,7月上旬进入羽化高峰期;同时分析研究了庭园丽金龟在湟源林区发生与寄主、树龄和温湿度的关系。
Phyllopertha horticola Liunaeus attackingHippophae rhamn in Huangyuan county was observed.The result showed that one generation ofPhyllopertha horticola Liunaeus occurred in two year,with third instar larvae overwinter in soil.In June,adult emergence began and in July reached high peak.The research also showed that the occurrence ofPhyllopertha horticolaLiunaeus is highly related to host,tree age and temperature.
