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。
本文對湟源縣林區庭園麗金龜在沙棘上的髮生規律和危害特點進行瞭初步研究。結果錶明：庭園麗金龜在湟源縣2年髮生1代,以3齡幼蟲在土壤中越鼕,6月下旬成蟲羽化,7月上旬進入羽化高峰期;同時分析研究瞭庭園麗金龜在湟源林區髮生與寄主、樹齡和溫濕度的關繫。
본문대황원현림구정완려금구재사극상적발생규률화위해특점진행료초보연구。결과표명：정완려금구재황원현2년발생1대,이3령유충재토양중월동,6월하순성충우화,7월상순진입우화고봉기;동시분석연구료정완려금구재황원림구발생여기주、수령화온습도적관계。
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.
