Soybean looper (SBL), (Walker 1858) (Lepidoptera: Noctuidae), is one of the most damaging insect pests of soybean, (L.) Merr., in the mid-south region of the United States, and causes significant economic losses to cotton, sunflower, tomato, and tobacco crops in the United States, Brazil, and Argentina. Soybean production in the southern region accounted for 15.5% of the total production in the United States, and yield losses due to invertebrate pests were 5.8%, or 1.09 million metric ton, in 2022. As insecticide resistance of SBL continues to rise, the lack of alternate control strategies is a serious concern. Numerous studies have been reported on pest status, distribution, semiochemical-based attractant blends, pesticides and resistance mechanisms, host-plant resistance mechanisms, and molecular tools for controlling this pest in soybeans and other crops. However, there is no comprehensive review that summarizes and discusses these research on SBL and soybeans. The current management strategies for SBL remain heavily reliant on chemical insecticides and transgenic crops. In contrast, integrated pest management (IPM) strategies are needed to control the pest in an effective and environmentally friendly way. This review examines and synthesizes the literature on SBL as a significant pest of soybeans and other important crops, highlighting recent progress in ecological interactions, host plant defenses, and control strategies and identifying information gaps, thereby suggesting avenues for further research on this pest.
豆夜蛾(SBL),学名Chrysodeixis includens (Walker 1858)(鳞翅目:夜蛾科),是美国中南部地区对大豆(Glycine max (L.) Merr.)危害最大的害虫之一,在美国、巴西和阿根廷还会给棉花、向日葵、番茄和烟草作物造成重大经济损失。美国南部地区的大豆产量占全国总产量的15.5%,2022年因无脊椎动物害虫造成的产量损失为5.8%,即109万吨。随着豆夜蛾对杀虫剂的抗性不断增强,缺乏替代防治策略成为一个严重问题。关于该害虫的害虫地位、分布、基于信息素的引诱剂配方、杀虫剂及抗性机制、寄主植物抗性机制以及用于控制大豆和其他作物中这种害虫的分子工具,已有大量研究报道。然而,尚无全面综述总结和讨论这些关于豆夜蛾和大豆的研究。目前豆夜蛾的管理策略仍然严重依赖化学杀虫剂和转基因作物。相比之下,需要采用综合害虫管理(IPM)策略以有效且环保的方式控制该害虫。本综述审视并综合了关于豆夜蛾作为大豆及其他重要作物的主要害虫的文献,突出了在生态相互作用、寄主植物防御和防治策略方面的最新进展,识别了信息空白,从而为进一步研究该害虫指明了方向。
