Incidence of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) and pheromone trap captures of male moths in damask rose (Rosa × damascena Herrm.) under field conditions was studied for three years. Results indicated that peak infestation of H. armigera eggs/bud reported at 19, 14 and 17th week (0.51, 0.73, 0.32 eggs/bud) in first (May), second and third year (April), respectively. Feeding holes/bud was peak at 19, 17 and 18th week (2.12, 2.16 and 1.1 holes/bud) in first, second and third year, respectively. The number of larvae/bud was higher at 19th week (0.53 larvae/bud) in the first year and was followed by the third year at 17th week (0.52 larvae/bud) as compared with second year. Similarly, the number of larvae/flower was also higher at 20th and 17th week (0.68 and 0.59 larvae/flower) in the first and third year, respectively as the compared second year. H. armigera damage on flowers was significantly positively correlated with humidity (evening) and rainfall during first year. Whereas, larva/bud and larva/flower were also significantly positively correlated with humidity (evening) and temperature (max. and min.), respectively in second year. In third year, eggs/bud was significantly positively correlated with humidity (morning). The number of H. armigera moths captured in sex pheromone traps at 30 cm above crop canopy level was significantly higher in all the three years as compared to crop canopy level and 30 cm below crop canopy level.

在田间条件下，研究了棉铃虫（Helicoverpa armigeraHübner）（鳞翅目：夜蛾科）的发生率和捕获锦缎玫瑰（Rosa×damascena Herrm。）中雄蛾的信息素陷阱。结果表明棉铃虫的侵染高峰第一年（5月），第二年和第三年（4月）分别在第19、14和17周报告鸡蛋/芽（分别为0.51、0.73、0.32鸡蛋/芽）。第一，第二和第三年的进食孔/芽分别在第19、17和18周达到高峰（2.12、2.16和1.1孔/芽）。与第二年相比，第一年的幼虫/芽的数量在第19周（0.53幼虫/芽）更高，其次是第三年的第17周（0.52幼虫/芽）。同样，与第二年相比，第一年和第三年的第20周和第17周幼虫/花的数量也分别更高（0.68和0.59幼虫/花）。棉铃虫在第一年，对花朵的伤害与湿度（晚上）和降雨呈显着正相关。而第二年的幼虫/芽和幼虫/花与湿度（晚上）和温度（最高和最低）也呈显着正相关。第三年，鸡蛋/芽与湿度（早晨）显着正相关。与农作物冠层水平和农作物冠层水平下30 cm相比，在这三年中，在高于农作物冠层水平30 cm的性信息素诱捕器中捕获的棉铃虫蛾的数量显着更高。
