在美国，水稻种植在不同的地方，当地的环境条件影响着栽培实践和昆虫的多样性和丰富性。每个地点都有独特的害虫复合体，从播种到收获都会攻击水稻。然而，主要的害虫是水稻水象甲(LisorHoptrus Oryzophilus)和水稻臭虫(Oebalus Pugax)，前者分布在美国各地的水稻种植区，后者仅在南方水稻产区发现。杀虫剂是主要的控制策略，但正在研究开发替代方法。已经为这些和其他害虫制定了经济阈值，但研究仍在根据新的高产品种、相关的栽培措施和复杂的政府补贴计划来完善危害/害虫密度关系。昆虫学家必须与其他学科的研究人员合作，以解决这些复杂的问题，并最大限度地利用有限的研究资金。
Rice is grown in the United States in varied locations where local environmental conditions impact cultural practices and insect diversity and abundance. Each location harbors a unique complex of insect pests which attack rice from seeding to harvest. However, the key insect pests are the rice water weevil (Lissorhoptrus oryzophilus), distributed throughout the rice growing areas of the United States, and the rice stink bug (Oebalus pugax), found only in the southern rice producing states. Insecticides are the main tactics of control but research is underway to develop alternative methods. Economic thresholds have been developed for these and other pests but research continues to refine the damage/insect density relationships in light of new high yielding varieties, associated cultural practices, and complex government subsidy programs. Entomologists must cooperate with researchers in other disciplines to solve these complicated problems and make the most of limited research dollars.
