Noctuidae species trapped by light and population dynamics in Luohe region

2015年4—10月,在河南省漯河市农业科学院试验基地设置自动虫情测报灯,系统诱集夜蛾科昆虫并鉴定种类、数量和优势种,分析夜蛾种群和优势种的发生动态。结果表明,夜蛾科昆虫年诱集量23 478头,分别隶属于44种,发生盛期为7月下旬到8月中、上旬;甜菜夜蛾、二点委夜蛾和黏虫是优势种,前两者发生盛期分别在8月中、上旬和7月中、下旬,黏虫的发生盛期在5月下旬到6月中旬和7月中、下旬;迁飞性害虫是漯河地区灯下夜蛾昆虫的主要类群。

Species of Noctuidae and population dynamics of the dominant species were investigated by light trapping in test based on Luohe academy of agricultural sciences from April to October in 2015. In total, 23478 pieces of Noctuidae belonged to 44 species were trapped. Emergence peak of Noctuidae adults was from late July to early （or mid） August, and dominant species were Spodopera exigua （Hubner）, Athetis lepigone （Moschler） and Pseudaletia separata （Walker）.
