【摘要】 在福泉烟田设置黑光灯诱蛾 ,结果表明 :斜纹夜蛾及棉铃虫成虫种群数量季节性消长年度间变化大 ,强翅夜蛾年发生 2个世代 ,金弧翅夜蛾、掌夜蛾年发生多世代。烤烟大田生长期 :烟夜蛾种群数量低 ,到 8月或 9月出现成虫种群数量高峰期 ;鬼脸天蛾种群数量最少 ;银纹夜蛾种群数量保持较高水平 ,但幼虫对烤烟危害轻更多还原

【Abstract】 Trapping mothes using blacklight trap in tobacco field at Fuquan county, the results show that the (seasonal) (dynamics) of the population number of Prodenia litura (Fabricius) and Heliothis armigera (Hubner) changes by a wide margin (among) different years. Euxoa robusta EV. reproduces two generations every year, Tiracola plagiata (Walker) and Plusia (orichalcea)(Fabricius) reproduce several generations every year. During field growth period of (tobacco), the population number of (Heliothis) assulta (Guenee)is lower, its peak period of the population number of the (adult) appears in August or September. The (population) number of Acherontia lachesis Fabricius is the less among these mothes, but the population number of Plusia agnata staudinger keeps a higher level.更多还原
