Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae) is a cosmopolitan species that feeds on numerous cultivated plants and herbaceaus plants. Agrotis ipsilon causes significant economic losses in various agricultural products, especially in indisturial plants and vegetables in Turkey and worldwide. In this study, the effects on the biology and reproductive potential of lettuce ( Lactuca sativa L., Asteraceae), maize ( Zea mays L., Poaceae), sugarbeet ( Beta vulgaris var. saccharifera Alef.,Amaranthaceae) and potato ( Solanum tuberosum L., Solanaceae) which are essential host plants of A. ipsilon were investigated under climatized conditions of 28 ± 1 °C, 60% ± 10 r.h., and 16 h daily artificial light. The data obtained were analyzed by using an age-stage two-sex life table. Agrotis ipsilon had five larval stages fed on lettuce, whereas seven larval stages were fed on other host plants. Agrotis ipsilon showed the best development and reproduction on lettuce, followed by sugar beet. When A. ipsilon is reared on lettuce the intrinsic rate of increase ( r = 0.1237 d −1 ), finite rate of increase ( λ = 1.1317 d −1 ) and net reproductive rate ( R 0 = 403.06 offspring/individual) were found higher and the mean generation times ( T = 48.51 d) is shorter than those in other host plants. According to these results, A. ipsilon can cause the most damage to lettuce among studied plants.

Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae) (Lepidoptera: Noctuidae) 在不同栽培植物上的生命表

Agrotis ipsilon (Hufnagel)（鳞翅目：夜蛾科）是一种世界性物种，以许多栽培植物和草本植物为食。Agrotis ipsilon 对各种农产品造成重大经济损失，尤其是土耳其和世界各地的工业植物和蔬菜。本研究对莴苣（Lactuca sativa L.，菊科）、玉米（Zea mays L.，禾本科）、甜菜（Beta vulgaris var. saccharifera Alef.，Amaranthaceae）和马铃薯（Solanum tuberosum）的生物学和繁殖潜力的影响L., Solanaceae) 是 A. ipsilon 的重要寄主植物，在 28 ± 1 °C、60% ± 10 相对湿度和 16 小时人工光照的气候条件下进行了研究。获得的数据使用年龄阶段两性生活表进行分析。Agrotis ipsilon 有五个以生菜为食的幼虫阶段，而七个幼虫阶段以其他寄主植物为食。Agrotis ipsilon 在生菜上的发育和繁殖最好，其次是甜菜。当 A. ipsilon 在生菜上饲养时，发现内在增长率 ( r = 0.1237 d -1 )、有限增长率 ( λ = 1.1317 d -1 ) 和净繁殖率 ( R 0 = 403.06 个后代/个体) 更高平均世代时间（T = 48.51 d）短于其他寄主植物。根据这些结果，在所研究的植物中，A. ipsilon 对莴苣造成的损害最大。1317 d -1 ) 和净繁殖率( R 0 = 403.06 个后代/个体) 更高，平均世代时间( T = 48.51 d) 比其他寄主植物短。根据这些结果，在所研究的植物中，A. ipsilon 对莴苣造成的损害最大。1317 d -1 ) 和净繁殖率( R 0 = 403.06 个后代/个体) 更高，平均世代时间( T = 48.51 d) 比其他寄主植物短。根据这些结果，在所研究的植物中，A. ipsilon 对莴苣造成的损害最大。
