松锯蝇（膜翅目：松锯蝇科）是一种爆发性食草动物，分布在北美东部。Diprionidae科至少包含140种，对针叶树构成最持久的威胁，因为种群爆发可导致广泛的落叶。由于一些物种比其他物种更容易发生大规模、破坏性的暴发，物种鉴定对有效管理至关重要。虽然现有的分类钥匙主要基于成虫的内部形态，但在物种水平上，幼虫颜色特征、地理位置、越冬策略、寄主植物和卵模式等物种间的实质性差异可以用于诊断。本研究重点研究了分布于北美东部的Pinaceae-feeding Diprioninae亚科，该亚科共有25种。我们描述了Diprioninae的一般生物学，生命周期和宿主利用生态学，重点是在这个亚科中这些性状之间的变化。此外，我们还提供了物种鉴定工具，包括利用外部诊断特征的分类钥匙。最后，我们讨论了可用的管理策略。
Pine sawflies (Hymenoptera: Diprionidae) are eruptive herbivores found throughout eastern North America. The Diprionidae family, which contains at least 140 species, constitutes the most persistent threat to conifers as population outbreaks can cause widespread defoliation. Because some species are more prone to large, destructive outbreaks than others, species identification is critical to effective management. Although existing taxonomic keys are primarily based on internal adult morphology, substantial variation among species in larval color traits, geographic location, overwintering strategy, host plant, and egg patterns can be diagnostic at the species level. Here, we focus on the Pinaceae-feeding subfamily Diprioninae, of which there are 25 species in eastern North America. We describe the general biology, life cycle, and host-use ecology of Diprioninae, with an emphasis on the variation among these traits within this subfamily. In addition, we provide tools for species identification, including a taxonomic key that utilizes external diagnostic characteristics. Finally, we discuss available management strategies.
