Over the last decade, the Allegheny National Forest (ANF) in the USA has experienced issues with the regeneration of black cherry (). This study was conducted to investigate the effects of silvicultural treatment on the insect communities that may affect black cherry pollination and regeneration. We conducted a 2-year study to compare the abundance, richness, and diversity of insects in unmanaged, shelterwood seed-tree, and shelterwood clear-cut stands. Using pan traps, we sampled insects at the ground level and in the canopies of flowering mature black cherry trees. The results of this study showed significant increases in the abundance of insects captured in shelterwood seed-tree stands and in species richness and diversity of insects captured in the canopy of black cherry in shelterwood removal stands, indicating that silvicultural treatment affected the insect community significantly. The dominant insect order was Diptera (true flies, 72.91%, n = 12,668), and (Diptera: Hybotidae) was the dominant species comprising 33% of all insects found in the canopy of flowering black cherry. The findings in this study could help land managers in managing black cherry for its pollination and natural regeneration.
在过去十年中，美国阿勒格尼国家森林（ANF）的黑樱桃更新出现了问题。本研究旨在调查森林经营措施对可能影响黑樱桃授粉和更新的昆虫群落的影响。我们进行了一项为期两年的研究，比较了未经营、择伐留母树和择伐皆伐林分中昆虫的数量、丰富度和多样性。我们使用诱虫盘在地面和开花成熟黑樱桃树的树冠层采集昆虫样本。这项研究的结果表明，择伐留母树林分中捕获的昆虫数量显著增加，择伐皆伐林分中黑樱桃树冠层捕获的昆虫物种丰富度和多样性显著增加，这表明森林经营措施对昆虫群落有显著影响。优势昆虫目为双翅目（实蝇，72.91%，n = 12668），（双翅目：舞虻科）是优势物种，占开花黑樱桃树冠层发现的所有昆虫的33%。本研究的结果有助于土地管理者管理黑樱桃的授粉和自然更新。
