储藏产品病虫害造成的收获后损失对全球粮食保障和安全构成严重威胁。在仓储害虫中，由于缺乏关于其造成的数量和质量损失的重要证据，过去被忽视。自过去几年以来，它们的经济重要性已被全球许多研究人员认识到。已发表的报告建议，应将该害虫视为对全球粮食保障和安全的新风险。在美国、澳大利亚、英国、巴西、印度尼西亚、中国、印度和巴基斯坦都发现了寄生在储藏谷物上的粘虫。目前已鉴定出的储粮害虫约有16种。豆荚通常喜欢有真菌生长的被侵染的籽粒，但能够挖出受损或破裂的未受感染的谷粒的软胚乳。它们捕食造成的经济损失与虫害强度和种群数量成正比。据报道，这种害虫还会给人类带来健康问题。本文从害虫的经济意义出发，对其系统发育、分布、生物生态学、管理和害虫现状等方面进行了综述。
Post-harvest losses caused by stored product pests are posing serious threats to global food security and safety. Among the storage pests, psocids were ignored in the past due to unavailability of the significant evidence regarding quantitative and qualitative losses caused by them. Their economic importance has been recognized by many researchers around the globe since the last few years. The published reports suggest that the pest be recognized as a new risk for global food security and safety. Psocids have been found infesting stored grains in the USA, Australia, UK, Brazil, Indonesia, China, India and Pakistan. About sixteen species of psocids have been identified and listed as pests of stored grains. Psocids generally prefer infested kernels having some fungal growth, but are capable of excavating the soft endosperm of damaged or cracked uninfected grains. Economic losses due to their feeding are directly proportional to the intensity of infestation and their population. The pest has also been reported to cause health problems in humans. Keeping the economic importance of psocids in view, their phylogeny, distribution, bio-ecology, management and pest status have been reviewed in this paper.
