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.

 

Sumario

Bedellia somnulentella (Zeller) (Lepidoptera: Bedelliidae) es una plaga especialista de Convolvulaceae. Los daños a las plantas hospederas ocurren durante la fase larval, minando hojas jóvenes y maduras. Este articulo, es el primer reporte de B. sommulentella en territorio brasileño. Esta plaga fue observada en hojas jóvenes y maduras de Ipomoea patatas (L.) (Solanales: Convolvulaceae) en Diamantina, Minas Gerais, Brasil. El insecto transforma las hojas com la presencia de minas que mudan el color de la hoja a marrón amarillenta, reduciendo el área fotosintética. La presencia de B. sommulentella en Brasil hace necesaria su inclusión en programas de monitoreo de plagas en cultivos de papa dulce.
