1. We developed a multi-year insect emergence survey for the monitoring and detection of invasive non-native species at two urban arboreta in Boston, Massachusetts and New York City, New York. Arborists pruned and sequestered pieces of these trees for up to 2 years inside emergence containers.
2. Host material was sampled from 117 trees comprising 67 species from the two sites. From these samples, 15 370 beetles were identified from all families, including 246 buprestids (21 species), 822 cerambycids (29 species) and 8825 scolytines (46 species).
3. Individual emergence chambers employed two collection methods: phototaxis toward an attached collection cup and sweeping barrel contents following the sequestration period. Sweeping resulted in many species not collected from cups.
4. We documented 17 new state records for Massachusetts and New York and 143 new host associations for buprestids, cerambycids and scolytines, including 22 new host associations of non-native beetles on native host trees and 51 new host associations of native beetles on non-native hosts.
5. One buprestid species, not native to North America yet new to science, Agrilus sp. 9895, was discovered. The combination of new state records, new host associations and new species detections illustrates how this survey method can be effective and beneficial for detection purposes.

利用城市树木园检测本地和非本地木栖甲虫

1. 我们在马萨诸塞州波士顿和纽约市的两个城市树木园开展了一项多年期昆虫出现调查，以监测和检测入侵的非本地物种。树木学家在出苗容器中修剪和隔离这些树木长达 2 年。
2. 宿主材料是从这两个地点的 117 棵树中取样的，包括 67 种树种。从这些样本中，共鉴定出各科甲虫15 370只，其中牛甲虫246只（21种）、天牛科822只（29种）和scolytines 8825只（46种）。
3. 单个出射室采用两种收集方法：趋光性朝向附加的收集杯和在隔离期后清扫桶内的内容物。清扫导致许多物种没有从杯子中收集。
4. 我们记录了马萨诸塞州和纽约州的 17 个新州记录以及 143 个新的 buprestids、cerambycids 和scolytines 寄主协会，包括 22 个新的本地寄主树上的非本地甲虫寄主协会和 51 个本地甲虫在非本地寄主上的新寄主协会.
5. 一种 buprestid 物种，不是原产于北美但对科学来说是新的，Agrilus sp。9895，被发现。新状态记录、新宿主关联和新物种检测的结合说明了这种调查方法如何有效且有益于检测目的。
