The corn earworm, Helicoverpa zea (Boddie), is a polyphagous pest found throughout the United States, where it attacks many field and vegetable crops. Although H. zea has long been a traditional pest of sweet corn, its importance to this crop has increased dramatically over the past two decades. In this review, we summarize information critical for current and future management of H. zea in sweet corn production in the United States. First, we discuss the pest status of H. zea and its life history, including migration, infestation and larval development, diapause, overwintering, and abiotic factors that affect its biology. Next we describe monitoring methods, crop protection decision-making processes, chemical control options, and the use of genetic technologies for control of H. zea Alternative H. zea management options including biological control, cultural controls, host plant resistance, and pheromone disruption are also reviewed. The role of climate change and its effects on H. zea and its ecology are discussed, as well as the recent invasion of its relative, Helicoverpa armigera (Hübner), which is a major pest of corn in other parts of the world. To conclude, we suggest future research opportunities for H. zea and H. armigera management in sweet corn.
玉米穗虫，即棉铃虫（Helicoverpa zea (Boddie)），是一种多食性害虫，在美国各地均有发现，它会侵害多种大田作物和蔬菜作物。尽管棉铃虫长期以来一直是甜玉米的传统害虫，但在过去二十年里，它对这种作物的重要性急剧增加。在本综述中，我们总结了对美国甜玉米生产中棉铃虫当前和未来管理至关重要的信息。首先，我们讨论棉铃虫的害虫地位及其生活史，包括迁飞、侵染和幼虫发育、滞育、越冬以及影响其生物学特性的非生物因素。接下来，我们描述监测方法、作物保护决策过程、化学防治选项以及利用基因技术防治棉铃虫的情况。还综述了棉铃虫的其他管理选项，包括生物防治、栽培防治、寄主植物抗性和性信息素干扰。讨论了气候变化的作用及其对棉铃虫及其生态的影响，以及其近缘种棉铃虫（Helicoverpa armigera (Hübner)）最近的入侵情况，棉铃虫是世界其他地区玉米的主要害虫。最后，我们提出了甜玉米中棉铃虫和棉铃虫管理的未来研究机会。
