Abstract

The non-native wood-boring and symbiotic fungus-culturing Xylosandrus germanus (Blandford) was first reported in New York apple orchards in 2013. Trapping surveys have been conducted annually since to assist growers in timely applications of preventative control measures. In 2021, a similar-looking introduced species, Anisandrus maiche (Kurentsov), was identified in traps in west central New York. Anisandrus maiche was first recorded in 2005 in Pennsylvania but its history in New York was unclear due to potential misidentification. We collected and identified ambrosia beetles using ethanol-baited bottle traps in 2022 and 2023 in New York at 2 commercial apple orchards near Lake Ontario and 2 cider apple orchards in the lower Finger Lakes district. Traps were placed in a forest interior, the forest edge, and the orchard edge at each site. Xylosandrus germanus was trapped from mid-April into early October; it was abundant in the Lake Ontario region but less so in the Finger Lakes. In contrast, counts of A. maiche were very high in the Finger Lakes but extremely low near Lake Ontario. It was trapped from late-May to mid-September. Most other bark and ambrosia beetle species were uncommon. Captures of X. germanus and A. maiche were generally highest in the forest interior and declined toward the orchard edge, but each species was usually present in traps across habitats at the same time. Thus, the practice of trapping at forest edges should continue. Both species can potentially infest stressed trees, including in orchards, throughout the growing season.

纽约地区和生境对德国木沙蝇和马氏木沙蝇(鞘翅目:瓢虫科)丰度的影响
2013年,在纽约苹果园首次报道了非本地蛀木和共生真菌培养Xylosandrus germanus (Blandford)。此后每年进行诱捕调查,以协助种植者及时采取预防控制措施。2021年,在纽约中西部的陷阱中发现了一种类似的引进物种,Anisandrus maiche (Kurentsov)。2005年,人们在宾夕法尼亚州首次记录到大头蛇,但由于可能被误认,它在纽约的历史并不清楚。我们于2022年和2023年在纽约安大略湖附近的2个商业苹果园和手指湖区的2个苹果果园使用乙醇诱捕器收集并鉴定了ambrosia甲虫。在每个地点的森林内部、森林边缘和果园边缘放置陷阱。4月中旬至10月上旬捕获德国木沙鼠;它在安大略湖地区是丰富的,但在芬格湖较少。相比之下,芬格湖的maiche数量非常高,而安大略湖附近的maiche数量非常低。它从5月下旬被困到9月中旬。大多数其他树皮和凤仙花甲虫种类是罕见的。日耳曼小蠊和麦切小蠊的捕获量总体上以林内最高,向果园边缘下降,但两种小蠊通常同时在不同生境的陷阱中出现。因此,在森林边缘诱捕的做法应该继续下去。在整个生长季节,这两种真菌都有可能侵扰受胁迫的树木,包括果园。
