The microlepidoptera Bedellia somnulentella is a pest insect of Ipomoea batatas leaves, with the first report in South America, in the city of Diamantina, Minas Gerais state, Brazil, in 2018. The mining caterpillars of B. somnulentella cause damage to the leaf mesophyll of the host plant, Ipomoea batatas, an important crop which contributes to overcoming world food insecurity with high nutritional value. The objective of this work is to register the occurrence of B. somnulentella in I. batatas in the cities of Lavras and Salinas, located, respectively, in the southern and northern regions of Minas Gerais state, Brazil. The individuals of B. somnulentella were observed in field areas of the Universidade Federal de Lavras (21° 14′ S, 44° 58′ W, at an elevation of 919 masl) in Lavras and at the Instituto Federal do Norte de Minas Gerais (15° 27′ S, 44° 22′ W, at an elevation of 474 masl) in the city of Salinas. in production sites of the northeastern region These records increase the knowledge concerning the geographic distribution of this pest in the country and indicate the importance of developing strategic studies for pest contingency plans and integrated pest management (IPM). To monitor B. somnulentella in I. batatas, it is necessary to accompany the expansion of this pest in other regions, especially in the maof Brazil, a warmer region, and the southern states, with a milder climate.

微鳞翅目Bedellia somnulentella是巴西番薯叶的害虫，2018年在南美首次报告于巴西米纳斯吉拉斯州的迪亚曼蒂纳市。B。somnulentella的采食毛毛虫会破坏巴西的叶肉。寄主植物番薯番薯（Ipomoea batatas）是一种重要作物，它以高营养价值有助于克服世界粮食不安全状况。这项工作的目的是要注册的发生B. somnulentella在甘薯在拉夫拉斯和萨利纳斯，分别位于两个城市，在米纳斯吉拉斯州，巴西南部和北部地区。B. somnulentella的个体在拉夫拉斯联邦大学和北米纳斯吉拉斯州联邦研究所（南纬15°27′，萨利纳斯（Salinas）市海拔44°22′W，海拔474 masl。在东北地区的生产现场中，这些记录增加了对该国有害生物地理分布的了解，并表明了开展针对有害生物应急计划和有害生物综合治理（IPM）的战略研究的重要性。为了监测棉铃虫中的B. somnulentella ，有必要在其他地区，特别是在巴西的黑毛病，温暖的地区和南部各州，气候温和的情况下，伴随这种有害生物的扩散。
