Wagner Gonzaga Gonçalves,Kenner Morais Fernandes,Marcelo Silva Barcellos,Fernanda Pereira da Silva,Marcos Jorge de Magalhães-Júnior,José Cola Zanuncio,Gustavo Ferreira Martins,José Eduardo Serrão +7 more
TL;DR: The characterization of the midgut of B. morio supported an ecto-endoperitrophic circulation, contributing to a better understanding of the digestive process in this bee.
Journal ArticleDOI
Testes and Spermatozoa as Characters for Distinguishing Two Ant Species of the Genus Neoponera (Hymenoptera: Formicidae)
Marcelo Silva Barcellos,Luiza Carla Barbosa Martins,Jamile Fernanda Silva Cossolin,José Eduardo Serrão,Jacques H. C. Delabie,José Lino-Neto +5 more
