Abstract

"The soybean tentiform leafminer, Macrosaccus morrise/la (Fitch) (Lepidoptera: Gracillariidae), has recently emerged as a new pest of soybean, Glycine max (L.) Merrill (Fabales: Fabaceae), in the United States. This oligophagous microlepidopteran is native to North America and was historically restricted to two legume species, American hogpeanut,Amphicarpaea bracteata (L.) Fernald (Fabales: Fabaceae), and slickseed fuzzybean, Strophostyles leiosperma (Torr. &A. Gray) Piper (Fabales: Fabaceae). The first detection of M. morrise/la feeding on soybeans occurred in Qyebec, Canada, in 2016. New detections have been documented in commercial soybean fields in Minnesota, South Dakota, North Dakota, Iowa, and Nebraska. In 2025, M morrise/la was confirmed for the first time feeding on soybeans in Cooper County, Missouri." -- first page
