太行山低山丘陵区鳞翅目趋光性昆虫种群动态初报

Elemental study on the population dynamics of Lepidoptera phototactic insects in hill area of lower Taihang Mountain

摘要: 采用黑光灯引诱逐日调查的方法，研究了太行山低山丘陵区鳞翅目趋光性昆虫种群数量动态变化规律。结果表明，实验区鳞翅目趋光性昆虫共有206种，分属16科。玉米螟、木撩尺蛾、棉铃实夜蛾和豆荚野螟为优势害虫种群。昆虫种群动态可分为零星出现、连续少量出现和连续大量出现3种类型，揭示了鳞翅目昆虫种群数量变化规律，为制定防治害虫对策提供理论依据。

Abstract: By the black light lamp lure and investigation day after day,the population dynamics of Lepidoptera phototactic insects in hill area of lower Taihang Mountain is studied. Experimental results indicate that there are 206 kinds of phototactic insect species belonging to 16 families in this region.The dominant species include Ostrinia nubilalis(Hübner),Heliothis armigera(Hübner),Culcula panterinaria(Bremer et Grey),Maruca testulalis(Geyer).Three types of the population dynamics of phototactic insect species could be identified as sporadic appearance,successive appearance with small amount and successive appearance with great number.It reveals quantitative change of Lepidoptera insects and provides scientific basis for making correct policy of controlling the pests.
