将人口统计和食物消费联系起来,预测印度鞘翅目蚜虫的种群增长和危害潜力
已被确认为全球入侵害虫的秋虫(Spodoptera frugiperda (J. E. Smith))已严重威胁到印度的农业生产和粮食安全。为了在新的入侵栖息地针对蚜虫制定生态友好型害虫综合治理策略,了解该害虫的繁殖参数和危害潜力至关重要。本文研究了玉米(Zea mays L.)、爆米花(Zea mays everta Sturt)、甜玉米(Zea mays saccharata Sturt)、高粱(Sorghum bicolor (L.))和大豆(Glycine max (L.) Merr.)这五种寄主作物对笛琶蝽发育和食物消耗的影响。利用计算机模拟绘制了基于生命表和消耗率的不同寄主上的种群预测曲线。食蚜蝇在爆米花(28.02 天)、玉米(28.04 天)和甜玉米(28.31 天)上成虫前发育最快,而在大豆(34.83 天)上发育最慢。玉米上的净繁殖率、内在增长率和有限增长率最高。玉米上 S. frugiperda 的摄食潜力也最高。第六龄幼虫在玉米上的消耗量最大(19470.47 平方毫米),而在大豆上的消耗量最小(9033.67 平方毫米)。在 90 天的模拟期内,预计玉米、爆米花和甜玉米上的 S. frugiperda 生长最快,而大豆上的生长最慢。在非玉米寄主(高粱和大豆)上的幼虫和蛹存活率很高,这表明秋绵虫可能会阻碍它们的生产以及玉米-大豆间作系统的成功。基于龄期和双性生命表的模拟有助于预测施用杀虫剂的最合适时间,也有助于增加释放卵和幼虫寄生虫来控制秋绵虫。

期刊介绍: Agricultural and Forest Entomology provides a multi-disciplinary and international forum in which researchers can present their work on all aspects of agricultural and forest entomology to other researchers, policy makers and professionals. The Journal welcomes primary research papers, reviews and short communications on entomological research relevant to the control of insect and other arthropod pests. We invite high quality original research papers on the biology, population dynamics, impact and management of pests of the full range of forest, agricultural and horticultural crops.
