From 2012 through 2020, a survey of wheat stem sawfly, Cephus cinctus Norton, was conducted in wheat (Triticum aestivum L.) fields in Eastern Colorado. In 2013, results showed sawfly infestations concentrated in the northern part of the state with only a few highly infested sites, with 38 of the 94 sampled sites having any infestation (five of which had >50% infestation levels). By 2020 sawfly had been found in all eastern counties sampled, and 72 of the 106 sites sampled were found to contain sawfly (11 of which had >50% infestation levels). The spread of this pest across the Colorado wheat-growing region will have lasting economic effects. The information gathered from this and future surveys will inform wheat variety development and aid in management decisions made by growers across the state.
从 2012 年到 2020 年，在科罗拉多州东部的麦田里对小麦茎蜂（Cephus cinctus Norton）进行了调查。2013 年的结果表明，茎蜂的侵扰集中在该州的北部，只有少数几个高度侵扰的地点，在 94 个抽样地点中有 38 个（其中 5 个的侵扰水平超过 50%）有任何侵扰。到 2020 年，已在所有东部抽样县发现了茎蜂，在抽样的 106 个地点中有 72 个（其中 11 个的侵扰水平超过 50%）发现了茎蜂。这种害虫在科罗拉多州小麦种植区的蔓延将产生持久的经济影响。从这次和未来的调查中收集到的信息将有助于小麦品种的开发，并为该州的种植者做出管理决策提供帮助。
