Description of a bilateral gynandromorph in Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) from Brazil

Abstract

ABSTRACT A bilateral gynandromorph of Spodoptera frugiperda was reported for the first time from Minas Gerais State, Brazil. The specimen with this trait was found among the progeny of a laboratory rearing population and exhibited dimorphism in the antennae, wings, head, thorax, and abdomen. It had a male left side and a female right side. Both the external and internal genitalia were typically those of a male.
