The invasive larger grain borer, Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae), originating from Meso-America, is a devastating stored product pest of maize (Zea mays L.) and cassava (Manihot esculenta). This species can destroy up to 40% of stored maize within four months. Despite four decades of research, P. truncatus has spread throughout Africa, while decimating maize and cassava production. Given the continuing problems with P. truncatus, the likelihood for its continued range expansion under climate change, and its status as a species of concern in many countries, the objective of this review was to provide an updated and comprehensive freely accessible record of the distribution and spread, biology, development, and ecology, host preferences, chemical ecology, detection, and monitoring, and management of P. truncatus. We conducted a search of the literature from 1911 to 2021 using Google Scholar and Web of Science to find all papers related to key search terms. We found that P. truncatus has been recorded in 36 countries across the globe, including 21 now in Africa. A recent predictive model found that the insect has been limited to tropical and subtropical regions but could likely spread to temperate regions as temperatures rise with climate change. Conspecifics respond to their two component, male-produced aggregation pheromone early after eclosion, but quickly switch to other cues as older adults. At close-range, P. truncatus may use food cues, but host volatiles are not involved in long-range host finding of commodities. Research on managing P. truncatus has mostly focused on chemical control to the detriment of other tactics, with the most promising tactic likely to be the different hermetic storage technologies. Many outstanding areas of basic behavior and ecology remain to be assessed for P. truncatus. We highlight specific areas that should be prioritized for further work in order to better manage and reduce the impact of this invasive insect pest.

侵入性较大的螟螟Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae) 起源于中美洲，是玉米( Zea mays L.) 和木薯( Manihot esculenta )的毁灭性贮藏害虫。该物种可以在四个月内破坏多达 40% 的储存玉米。尽管进行了四年的研究，P. truncatus已经蔓延到整个非洲，同时减少了玉米和木薯的产量。鉴于P. truncatus的持续问题，其在气候变化下持续范围扩大的可能性，以及其在许多国家作为受关注物种的地位，本次审查的目的是提供分布和传播、生物学、发展和P. truncatus 的生态学、寄主偏好、化学生态学、检测、监测和管理。我们使用 Google Scholar 和 Web of Science 对 1911 年至 2021 年的文献进行了搜索，以查找与关键搜索词相关的所有论文。我们发现P. truncatus已在全球 36 个国家/地区进行了记录，其中 21 个现在在非洲。最近的一个预测模型发现，这种昆虫仅限于热带和亚热带地区，但随着气温随着气候变化而上升，它可能会扩散到温带地区。同种动物在羽化后早期对它们的两个组成部分做出反应，雄性产生的聚集信息素，但随着年龄的增长，它们很快就会转向其他线索。在近距离，P. truncatus可能使用食物线索，但宿主挥发物不参与商品的远距离宿主发现。蒺藜防治研究主要专注于化学控制而损害其他策略，最有前途的策略可能是不同的密封存储技术。P. truncatus的基本行为和生态学的许多突出领域仍有待评估。我们强调了应优先开展进一步工作的特定领域，以便更好地管理和减少这种入侵性害虫的影响。
