Abstract
Bedellia somnulentella Zeller, 1847 (Lepidoptera: Bedelliidae), a global pest of the sweet potato Ipomoea batatas, was recorded in Brazil, but morphological information on the sexual dimorphism of this insect is scarce. The objective was to evaluate morphological characters of sexual dimorphism of B. somnulentella pupae and adults. External structures with sexual dimorphism were not detected in the last abdominal segments of B. somnulentella pupae. The females of this insect are heavier, which could be a distinctive sex characteristic. A pair of frenulum on the hind wings of females and only one on those of males, in addition to elongated cerci and bipartite genitalia in the latter and smaller cerci involving the last abdominal segment and an ovipositor in females, differentiate sexes of B. somnulentella.
期刊介绍:
Neotropical Entomology is a bimonthly journal, edited by the Sociedade Entomológica do Brasil (Entomological Society of Brazil) that publishes original articles produced by Brazilian and international experts in several subspecialties of entomology. These include bionomics, systematics, morphology, physiology, behavior, ecology, biological control, crop protection and acarology.
