(Stål) and (Fabricius) are two exotic invasive pests that have invaded the United States in recent years. can damage various fruits, vegetables, and field crops, such as soybean and corn, while only attacks soybean and kudzu, a weed species. They are currently found in southeastern states and threaten soybean and other crops grown in the region. This study evaluated the seasonal abundance of . and . in soybeans in 2016 and 2017 in two counties in the central region of Tennessee, where both species had either a few sightings or none that were recorded when this research was being planned. Lures and sweep sampling were used to monitor . , and sweep sampling was used to monitor . . was first detected in samples in late July. Their numbers increased in early to mid-September, reached the economic threshold in late Sept, and then started to decline. was first detected in mid to late July, increased their populations in September, but did not reach the economic threshold and declined mid-October. Our results showed the seasonal abundances of . and . and their establishment in the central region of Tennessee.
(斯塔尔)和(法布里修斯)是近年来入侵美国的两种外来入侵害虫。(斯塔尔)会损害各种水果、蔬菜和大田作物,如大豆和玉米,而(法布里修斯)只攻击大豆和杂草葛藤。它们目前在东南部各州被发现,并威胁到该地区种植的大豆和其他作物。本研究评估了2016年和2017年田纳西州中部两个县大豆中(斯塔尔)和(法布里修斯)的季节性丰度。在规划本研究时,这两个物种在这两个县要么只有少数几次目击记录,要么没有记录。使用诱捕器和扫网采样来监测(斯塔尔),并使用扫网采样来监测(法布里修斯)。(斯塔尔)于7月下旬首次在样本中被检测到。它们的数量在9月初至中旬增加,在9月底达到经济阈值,然后开始下降。(法布里修斯)于7月中旬至下旬首次被检测到,其种群数量在9月增加,但未达到经济阈值,并在10月中旬下降。我们的结果显示了(斯塔尔)和(法布里修斯)在田纳西州中部的季节性丰度及其定殖情况。
