摘　　要：为明确云南澜沧地区旱地作物金龟子种群的发生动态,于2023年通过灯光诱集对云南省普洱市澜沧各地旱地作物金龟子的种类、优势种群的发生动态及其雌雄性比进行系统调查。结果表明,澜沧全区共采集到金龟子3科7属13种,主要优势种为小黄鳃金龟Metabolus flavescens、黑条异丽金龟Anomala vittata、黑阿鳃金龟Apogonia cupreoviridis和暗黑鳃金龟Holotrichia parallela,分别占诱虫总数的46.66%、18.20%、13.04%和7.35%。澜沧地区金龟子发生盛期为5月下旬至6月下旬,金龟子出土前期随温度持续上升开始大量出土,并于5月25日、6月9日和6月19日出现3个高峰期。小黄鳃金龟和暗黑鳃金龟的发生期为5月中旬至7月中旬,黑条异丽金龟的发生期为5月中旬至6月底,黑阿鳃金龟的发生期为5月中旬至7月下旬。暗黑鳃金龟和黑条异丽金龟雄虫多于雌虫;小黄鳃金龟雌虫多于雄虫。综上,澜沧地区金龟子种类丰富,小黄鳃金龟是优势种,金龟子出土盛期在5月和6月,该研究将为澜沧地区旱地作物金龟子的精准防治提供理论依据。To clarify the population dynamics of scarabs on upland crops in the Lancang area of Yunnan province,this study systematically investigated scarab species,dynamics of dominant populations,and their gender ratios in upland crop fields in Lancang county,Pu’er city,Yunnan province in 2023 using light traps.The results showed a total of 13 species,7 genera and 3 families.The main dominant species were Metabolus flavescens,Anomala vittata,Apogonia cupreoviridis,and Holotrichia parallela,representing 46.66%,18.20%,13.04%,and 7.35%of the total scarab population,respectively.The peak period of scarabs occurrence in Lancang area was from late May to late June,and a lange number of scarabs discoveries began with the continuous rise of temperature in the early stage of excavation,and three peak periods appeared on May 25,June 9 and June 19.Species-specific occurrence periods varied:M.flavescens and H.parallela were active from mid-May to mid-July,A.vittata from mid-May to late June,and A.cupreoviridis from mid-May to late July.Additionally,there were more males than females in A.vittata and H.parallela,while M.flavescens populations had a higher proportion of females.The Lancang area has abundant scarab species,with M.flavescens as the dominant species.Peak scarab emergence occurs in May and June.This study provides a theoretical basis for precise scarab control in upland crops in the Lancang area.
