Abstract

First record of the sweet potato pest Bedellia somnulentella (Lepidoptera: Bedelliidae) in Brazil.

Abstract

Bedellia somnulentella (Zeller) (Lepidoptera: Bedelliidae) is a specialist Convolvulaceae pest. Its larvae damage host plants by mining young and mature leaves. This is the first report of B. somnulentella in the Brazilian territory. This pest was observed on young and mature Ipomoea batatas (L.) (Solanales: Convolvulaceae) leaves in Diamantina, Minas Gerais State, Brazil. This insect alters the leaf appearance due to its mines, changing the leaf color to yellowish-brown, which reduces the photosynthetic area. The presence of B. somnulentella in Brazil makes it necessary to include this insect in pest monitoring programs in sweet potato plantations.
